- Myotonic dystrophy or dystrophia myotonica (DM) is a hereditary neuromuscular multisystem disease with a varying clinical expressivity and severity. The objective of this study was to assess the oral health in children with myotonic dystrophy and to compare it with a control group. Fifty-six DM patients, aged 2.7-18.0 yr, were compared with age- and gender-matched control patients with respect to caries, plaque, and gingivitis. Oral function and signs of temporomandibular dysfunction (TMD) were assessed, and the ability to co-operate in dental treatment was estimated. Questionnaires concerning eating habits, dental care, traumatic injuries to teeth, and orofacial function were also used. The DM patients had significantly more caries, plaque, and gingivitis than did control patients. They had more TMD problems and lower co-operation ability than the healthy control persons. General sedation was frequently needed to carry through dental treatment. DM patients are at risk of caries, gingivitis and TMD problems, and need intensified prophylactic care. Behavior management problems are common.

- AIM: The aim of this longitudinal study was to evaluate changes in oral health, orofacial function, and dental care in children with myotonic dystrophy type 1 (DM1) in comparison with a control group. METHODS: Thirty-six DM1 patients and 33 control patients out of originally 37 in each group were examined on two occasions about 4 years apart. Caries, plaque, and gingivitis were registered, mouth opening capacity assessed and the ability to cooperate in dental treatment estimated. Questionnaires concerning different aspects of oral health and care, symptoms of temporomandibular dysfunction (TMD), and dental trauma were also used. RESULTS: The DM1-patients, in particular the boys, had significantly more caries, plaque, and gingivitis than the control patients on both occasions and the increase in decayed missing or filled permanent teeth (DMFT) and surfaces (DMFS) was significantly larger. They received more dental care and had lower cooperation ability. Mouth opening capacity and increase of it was significantly lower and symptoms of TMD were significantly more frequent. CONCLUSIONS: DM1 patients, as they grow older, have increasing amounts of plaque and risk of caries and gingivitis. They have more TMD problems. Behaviour management problems do not seem to decrease with age. Increased prophylactic care is essential for DM1 patients.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the study was to reduce everyday and dental treatment pain items included in the extended Children's Pain Inventory (CPI), used in a prior study on Swedish children and adolescents. Another aim was to, by means of exploratory factor analysis (EFA), expose hitherto undiscovered dimensions of the CPI pain variables and thus to improve the psychometric properties of CPI. As some pain items are relevant merely to some individuals, a new and more useful questionnaire construction would enhance the internal validity of the instrument in observational surveys. EFA was applied on the extended CPI instrument. 368 children, 8-19 years old, had answered a questionnaire comprising 10 dental and 28 everyday pain variables. These pain items were analysed using a series of sequentially implemented EFA. Interpretations and decisions on the final number of the extracted factors was based on accepted principles; Kaiser's Eigenvalue >1 criterion, inspection of the scree plot and the interpretability of the items loading. The factors were orthogonally rotated using the Varimax method to maximize the amount of variance. Of all tested EFA models in the analysis, a two, three, four, and five factor model surfaced. The interpretability of the factors and their items loading were stepwise examined; the items were modulated and the factors re-evaluated. A four factor pain model emerged as the most interpretable, explaining 79 % of the total variance depicting Eigenvalues >1.014. The factors were named indicating the profile of the content: Factor I cutting trauma to skin/mucosal pain, Factor II head/neck pain, Factor III tenderness/blunt trauma pain, Factor IV oral/dental treatment pain.

- Aim: This was, firstly, to study the occurrence of oral pain and discomfort, using the Dental Discomfort Questionnaire (DDQ), in children and adolescents with intellectual or physical disabilities, compared with controls. Secondly, was to analyse the relationship between pain and discomfort, as measured by the DDQ, and dental health, as well as oral hygiene habits and dietary habits. Methods: The study included 135 children and adolescents (12–18years), registered at the Child and Adolescent Habilitation Unit in Göteborg and Södra Bohuslän, Sweden, and 135 gender- and age-matched controls. The children’s legal guardians completed a questionnaire comprising the DDQ and questions on oral hygiene and dietary habits. Data on dental health were retrieved from dental records. Results: The DDQ total mean score was higher for the study group, compared with the control group, 3.2 (SD 2.9) vs. 1.6 (SD 2.0), respectively (p = 0.001). Furthermore, children and adolescents with a severe intellectual disability had higher total mean DDQ scores than children with a mild intellectual disability, 4.8 (SD 4.2) vs. 2.4 (SD 2.9), respectively (p=0.034), and also higher than children with a physical disability, 2.2 (SD 2.1) (p=0.012). There were no differences in DMFT between children with disabilities and age-matched controls. There was no relationship between the DDQ scores and oral hygiene/dietary habits in children with disabilities. Conclusions: Children and adolescents with intellectual or physical disabilities experienced oral discomfort and pain more often than matched controls. Dental health expressed as DMFT could not be related to the DDQ responses. © 2016, European Academy of Paediatric Dentistry.

- The purpose of this retrospective study (15 years follow-up) was to evaluate the long-term results of treatment to injured teeth following acute trauma. A total of 198 patients with 488 injured teeth were available for analysis. Uncomplicated crown fractures were restored with composite restorations in 106 teeth. 19% of the restorations had been replaced more than 10 times and at the final examination approximately 25% were rated as unacceptable, i.e. needing clinical treatment. Fixed prosthetic therapy had been provided for 106 teeth and endodontic treatment had been provided in 114. Colour changes appearing at late stage suggested obliteration, necrosis or endodontically treated teeth. Anterior composite restorations have been considered acceptable as semi-permanent restorations in patients of early school age (7-15 years), and may have been an advance on what was possible previously, but results of this clinical study suggest that they still do have major shortcomings. There remains a need for a simple, conservative method of restoring aesthetics to fractured and discoloured anterior teeth for clinical use in young patients of late school age.

- Children born extremely preterm often suffer from medical complications that have been shown to affect their oral health as toddlers and school children.The aim of this study was to investigate oral health and possible risk indicators for poor oral health in adolescents born extremely preterm compared with a control group and relate the findings to medical diagnoses at the clinical examination. Also in the same groups, compare the frequency of mineralization disturbances and its relation to postnatal morbidity and treatments. The medical records postnatally,was noted in 45 extremely preterm infants with a gestational age (GA) of <29 weeks, at 12 - 16 years of age and in age and gender matched fullterm controls with 37-43 weeks GA. A dental clinical examination was performed including a salivary examination. Medical diagnoses were noted at the time of the survey. Data from the patient dental records at 3, 6, and 9 years of age was compiled. The findings were related to gestational age, birth weight, neonatal and postnatal medical diagnoses treatments and medical diagnoses at the clinical examination. The result showed that the prevalence of plaque, gingivitis and the occurrence of Streptococcus mutans were higher among adolescents born extremely preterm compared to matched controls, and the saliva secretion was lower in the extremely preterm infants. The frequency of caries did not differ between the groups. Mineralization disturbances were more frequent in the primary dentition and more severe in the permanent dentition among the children born extremely preterm. No association between dental pathology, neonatal and postnatal morbidity and treatments was found. In conclusion, adolescents born extremely preterm have an increased number of risk indicators for a poorer oral outcome compared with the controls and more severe mineralization disturbances. These findings may imply an increased vulnerability for poorer oral health later in life.

- Purpose Amelogenesis imperfecta (AI) is a hereditary condition which affects the composition and structure of enamel in terms of hypoplasia and/or hypomineralization. The condition severely affects patients facing such difficulties as hypersensibility, loss of tooth substance and poor aesthetics. The objective is to perform a systematic review of patient-reported outcome measures (PROMs) in patients with amelogenesis imperfecta. Methods Inclusion criteria were articles written in English, including PROMs from patients with amelogenesis imperfecta. The databases PubMed, Scopus and Web of Science were searched on April 27, 2022, and eligible articles were screened. Exclusion criteria were articles based on proxy reports and single case reports. Results 405 studies were screened in terms of title and abstract, with 31 articles eligible for full-text screening, resulting in a total of 11 articles eligible for inclusion, (articles including 4-82 patients). The content was analyzed, resulting in the outcome divided into seven domains: Oral Health-Related Quality of Life (OHRQoL), Dental fear, Esthetics, Psychosocial factors, Function, Dental hypersensitivity, and Treatment outcome. Conclusion The limited quantity of research on PROMS from patients with AI indicates a significant impact of OHRQoL and daily life. A large variety of approaches have been presented in the articles. Patients report concerns of esthetics, hypersensitivity, function, and a general impact on well-being and social interaction. This highlights the importance for the need of early dental treatment.

- Objectives: This study aimed to further investigate the heterogeneity within the group of children referred for specialist treatment because of dental behavior management problems (DBMP). A specific aim was to evaluate the validity of a previously reported cluster structure in another DBMP study group. Methods: 177 child dental patients, aged 4 to 12 at referral to a specialist pediatric dental clinic in Göteborg, Sweden, were classified into subgroups according to their personal characteristics. Cluster structure was described and compared to previously reported findings in a DBMP study group of same-aged child dental patients in Örebro, Sweden (n=74). Parental assessments of children's dental and general fear, temperament and behavior were made pre-treatment. The children also performed a vocabulary test. Data were analyzed mainly with a person-based approach using sequences of cluster analyses. Results: Classification into five different subgroups was judged the best representation of the Göteborg study group data, while four groups had been defined in Örebro. The new clusters partly paralleled the previous and were labeled (I) Extrovert, outgoing, (II) Highly fearful, multiple problems, (III) Highly fearful, (IV) Moderately fearful, externalizing, impulsive and (V) Moderately fearful, inhibited. Cluster profile II describes severe dental fear and general temperamental and behavioral problems of internalizing as well as externalizing character. Such combined problems were not clearly revealed in the Örebro cluster structure. Conclusion: The contention that children with dental behavior management problems (DBMP) comprise a heterogeneous group was strengthened. Similar, although not identical, clusters of children showing DBMP were identified in this replication study. Apart from different levels of dental fear, varying temperamental and behavioral characteristics need to be taken into consideration to better match treatment for these patients

- The reported skew distribution of caries prevalence in preschool children, with a small group of children with very high caries prevalence, stresses the importance of early identification for prevention. The present study aimed to describe the caries prevalence in a group of Swedish preschool children and to identify caries risk factors in this population. 221 children, 2 to 3 years old, agreed to participate in the study (82%). A standardized questionnaire was used to describe socio-economic factors, dietary and oral hygiene habits and exposure to fluoride. Initial and manifest dental caries was diagnosed and the presence of plaque was visually observed without disclosing solution. Saliva and plaque samples were collected for identification of mutans streptococci (MS). For statistical analysis,the Student's t-test,the Chi-square test and Fisher's exact test were used. The caries prevalence among the 2 to 3 year-olds was 7 and 18 percent respectively. An association between early childhood caries and a number of factors was found e.g. the presence of MS and visible plaque, nocturnal meals, frequent sugar consumption, mothers' state of employment and immigrant background. The Public Dental Health Service has been successful in decreasing the number of children with caries, but the challenge remains to be able to control caries in the high-risk group. The skew distribution, with many children without caries and a smaller group with very high caries prevalence, was confirmed. The study provided insight into various factors, useful for monitoring children at risk of developing early childhood caries.

- Abstract: Aim Identification of potential carious risk criteria, retrospectively at 2 years of age, for developing carious lesions at 3 years of age. Study design Longitudinal observations from 2 until 3 years of age. Cross-sectional observations of two cohorts of 3- year-olds with different approaches. Materials and methods The study group consisted of 78 three- year-olds from a previous study at age 2 years. Clinical examination, diet history, questions regarding breastfeeding and salivary sampling for mutans streptococci (MS) were performed at both ages. The previous study on 124 three-year-olds was used as a control group for comparison of the 3-year-olds in the longitudinal study group. Results The examinations suggested the following risk predictors: carious lesions, frequent intake of selected sugar-containing products, breast feeding at night and MS, which covered all children with lesions at 3 years of age, resulting in a positive predictive value of 32% and a negative predictive value of 100%. The only statistically significant difference between the two groups of 3-year-olds was the reported intake of sugar-containing items. Statistics Student's t-test and chi(2) test, completed by Fischer's exact test. Conclusion The combination of the suggested risk criteria was predictive of carious lesions. In spite of individual parental information, new lesions developed after one year. Based on observations, a more structured and monitored preventive approach is suggested.

- The aim of this study was to in vitro evaluate the micro leakage of a fissure sealant on sound and demineralized enamel using thermo cycling. The effect of the sealing procedure on sound and demineralized enamel were assessed on human premolars that were divided into one Control group and two Test groups. The Control group served as a baseline reference for the subsequent test procedures. The crowns of five teeth were covered with wax leaving three separate windows on the buccal surfaces. The enamel in one window was acid-etched, in the second window demineralized, and in the third window demineralized and subsequently acid-etched. In Test group 1, containing ten teeth, a defined enamel area on the buccal surfaces was acid-etched and sealed. The sealed area and a border of sound enamel around it were subjected to the demineralizing procedure. In Test group 2, a defined enamel window of 13 teeth was demineralized and subsequently etched and sealed. The sealed area and a border of surrounding enamel were subjected to a new cycle of demineralization. The longitudinal, bucco-lingual sections were examined in polarized light. When placed on acid-etched surfaces, the resin adhered firmly to the enamel with no evidence of demineralization or enlargement of previously demineralized areas underneath the sealants.

- Aim To investigate the frequency and reported intensity levels of dental treatment pain and discomfort in children, in conjunction with regular dental visits. Methods The study included 2363 children in four different age cohorts. Data was collected from structured interviews by dental personnel regarding pain experiences or discomfort after treatments, including analgesia, extractions, operative treatments and radiographic examinations. Results One-third of all treatment occasions were experienced as painful and/or causing discomfort. Treatment sessions including analgesia were assessed as painful in 49.7% of occasions, with injection being the most common given reason for pain. Extraction was painful in 62.4% of occasions, with injection as the main reason for pain. Operative treatments were assessed as painful in 38.8% of occasions, with drilling as the most common reason for pain and discomfort. Pain was reported in approximately 19% of all radiographic examinations. Conclusions Injection was the major reason for pain during treatment, including injection and extraction, while drilling was the most common cause of pain during restorative treatment. Dentists should try to minimise the experience of pain and discomfort by using all available measures to perform pain-free and effective dental injections.

- PurposeThe aim of this study was to investigate attitudes and preferred therapy choice for first permanent molars (FPM) with Molar-Incisor Hypomineralization (MIH).MethodsAn online questionnaire was sent out to general dentists (n = 559) working in the Public Dental Service in Region Vastra Gotaland, orthodontists (n = 293), and pediatric dentists (n = 156) (members from each interest association), in Sweden. The questionnaire contained three parts: general questions regarding the respondents, patient cases, and general questions regarding extraction of FPMs with MIH. Statistics were carried out using Chi-squared tests, with a significance level of 5%.ResultsA response rate of 36% was obtained. Orthodontists and pediatric dentists were more prone to extract FPMs with both moderate and severe MIH, compared to general dentists. When restoring FPMs with moderate MIH, resin composite was preferred. Compared to the general dentists, the pediatric dentists were more prone to choose glass-ionomer cement in the FPMs with severe MIH. The most common treatment choice for FPMs with mild MIH was fluoride varnish. "When root furcation is under development of the second permanent molar on radiographs" was chosen as the optimal time for extracting FPMs with severe MIH, and the general dentists based their treatment decisions on recommendations from a pediatric dentist.ConclusionExtraction of FPMs with moderate and severe MIH is considered a therapy of choice among general dentists and specialists, and the preferred time of extraction is before the eruption of the second permanent molar.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To investigate the use of optical coherence tomography (OCT) as a tool to assess general and localised hypomineralisation defects in the enamel. Design and Materials: Ten extracted permanent teeth (four teeth with localised hypomineralisa-tion, four teeth with general hypomineralisation, and two healthy controls) were used in this study. In addition, four participants who underwent OCT served as living controls for the extracted teeth.Methods: The OCT results were compared with clinical photographs, digital radiographs, and polarising microscopy images of tooth sections (considered the gold standard) to determine the method with the most accurate information regarding the extent of enamel disturbances: 1) visibility of enamel disturbance (visible yes/no); if yes, 2) extent of the disturbance in the enamel; and 3) determination of the plausible involvement of the underlying dentin.Results: OCT was more accurate than digital radiography and visual assessment. OCT could provide information about the extent of localised hypomineralised disturbances in the enamel that was comparable to that with polarisation microscopy of the tooth sections.Conclusion: Within the limitations of this pilot study, it can be concluded that OCT is suitable for investigating and evaluating localised hypomineralisation disturbances; however, it is less useful in cases with generalised hypomineralisation of the enamel. In addition, OCT complements radiographic examination of enamel; however, more studies are necessary to elucidate the full extent of the use of OCT in case of hypomineralisation.

- To investigate the predictive ability of individual Caries Risk Assessments (CRA) regarding oral factors supplemented with social factors in relation to caries outcome in preschool children. Furthermore, to assess various models of CRA with oral and social factors included, aiming to identify the most suitable models for different age groups.The design is a retrospective registry-based cohort study. Children visiting the dentists at ages 3 and 6years were included. Data on oral and social factors were obtained from dental records, the Swedish Quality register for caries and periodontitis (SKaPa), and Statistics Sweden (SCB). Various models of CRA were designed, combining oral and social factors. Models were analyzed with univariable associations using simple logistic regression, and the results were presented as odds ratios (ORs). In addition, models were analyzed with area under the receiver operating characteristic (ROC) curve (AUC). Pairwise comparisons were conducted by DeLong's test, with p<0.05 considered significant.Oral factors were the most significant for caries outcome (OR 9.6), followed by social factors: foreign background (OR 4.6), low income (OR 2.83), low education of the mother (OR 2.77), single-parent family (OR 2.11), and having≥3 siblings (OR 1.71), (p<0.01). The predictive ability of CRA improved when models combining oral and social factors were used, compaired to CRA based solely on oral factors (p<0.05). An increase of up to 15% was seen when CRA was conducted closer to the outcome.Models for Caries Risk Assessment including oral and social factors increase the predictive ability. Caries Risk Assessment has limited durability.

- Purpose Molar Incisor Hypomineralization (MIH) are first molars with developmental enamel defects and are common findings in many child populations. The porous nature of MIH enamel and the presence of post-eruptive enamel breakdown leads to the presence of hypersensitivity and pain, which is often the patient's main complaint and can result in dental fear and affect the quality of life. The present review aims to summarise the evidence for the ability of MIH to cause problems, such as dental fear and anxiety (DFA) and to summarise the evidence for a possibly negative impact on the oral health-related quality of life (OHRQoL) of MIH affected children and adolescents, in a systematic review. Method Two searches, (1) MIH AND dental anxiety and (2) MIH AND Quality of life, were performed in MEDLINE/PubMed and Scopus. Selection demands were fulfilling the MIH diagnosis criteria using validated instruments and questionnaires for assessing DFA and OHRQoL, respectively. Results After removing duplicates and articles not fulfilling the selection demands, 6 studies concerning MIH and DFA and 8 studies concerning MIH and OHRQoL remained. Conclusion Children and adolescents with diagnosed MIH did not seem to suffer from increased dental fear and anxiety, but indicated an impaired oral health-related quality of life.

- Aim: To evaluate the ability to recognise different types of developmental defects of enamel (DDE) by a group of general dental staff, trained prior to the comprehensive prevalence study (the BITA study), and to compare their skills to that of an untrained group. To evaluate the validity and reliability of the DDE registrations and MIH diagnoses, 3 years after the BITA study ended. To evaluate the reliability of an MIH diagnose, 3 years after the study ended. Materials and methods: The dental staff from five clinics (n = 43) was given instructions in identifying different types of DDE, according to the mDDE index (FDI in Int Dent J 42:411–426 1992). A test protocol with 24 digital photos of teeth with different DDE was filled out. The dental staff from five other clinics (n = 60), without preceding instructions, also filled out the protocol. Ninety-one patients with reported DDE were clinically re-examined 3 years later by two dentists with certified experience of DDE. Results: When untrained dental staff filled out the test protocol, only 42% of the affected surfaces were correctly assessed, whereas 85% of the dental staff instructed in recognizing DDE made a correct assessment (p < 0.000). The specialists confirmed 73% of the teeth diagnosed with DDE in the BITA study as affected. The agreement in judging the opacities as diffuse or demarcated was 76%. One-fourth of those being judged to be affected by MIH in the BITA-study also showed to be affected by other enamel disturbances. Conclusions: The ability of the untrained dental staff to recognize DDE was insufficient. Instructions, using digital photos, raised the ability considerably. To ensure a correct MIH diagnosis, the patients should be followed until all the permanent teeth have erupted. © 2019, The Author(s).

- To describe the prevalence of different types of developmental defects of the enamel (DDE) in varying age-cohorts and habitations, and to analyse if early trauma to the primary teeth and early subsequent serious health problems were related to DDE in the permanent dentition. Dental fear and anxiety, and aesthetic problems as a consequence of DDE were also investigated. DDE was registered over 5 years annually in three age cohorts (796 children). The DDE index (FDI Commision on Oral Health, Research and Epidemiology, Int Dent J 42:411-426, 1992) was used. Information on diseases in early childhood, trauma to the primary teeth, and dental fear and anxiety were collected. The prevalence of DDE was 33.2% (boys 37.1%, girls 29.3%, p = 0.02). Demarcated opacities (DEO), solely, were the most frequent kind of defect, affecting 18%. Five percent (5%) had diffuse opacities (DIO) and 1% had hypoplasias, whereas 7% had teeth with both DEO and DIO. The most frequently affected teeth of DEO, as well as of DIO, were the first permanent molars and maxillary central incisors. Dental injuries to the primary anterior teeth raised the risk for DDE in the permanent teeth, but early serious health problems did not. Generalised DDE was common (8.4%). The paediatric dentists assessed the DDE in the maxillary anterior teeth as more serious than did the affected children and their parents. Generalised DDE was more frequent than expected, as well as the occurrence of both DEO and DIO in the same individual. The first permanent molars and the upper central incisors were the most affected teeth.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Very little is known about children's everyday pains and dental treatment pains. A child's gender, age, and level of dental anxiety are factors that could interplay with the perception of pain and are thus worth studying. AIM: The objectives of this study were to investigate the frequency and reported intensity levels of children's everyday- and dental-pain experiences, and to study the reported pains in relation to gender, age, and dental anxiety. DESIGN: Three hundred and sixty-eight consecutive patients (8-19 years, mean age 13.5 years) from three different Public Dental Service were recruited. Pain ratings were obtained using McGrath's Children's Pain Inventory list and some additional items. Dental anxiety was estimated by the Dental Anxiety Scale. RESULTS: Most frequently experienced everyday pains were headache and tummy/stomach ache. Among dental treatment events, dental injection was reported to be most often ranked as painful, and more frequently by girls. Both dental and everyday pains were rated higher grouping children with high dental anxiety. CONCLUSIONS: The frequency of pain experiences are the same in Swedish children as in other populations. There is a relation between dental anxiety and the perception of pain.

Tidskriftsartikel (refereegranskat)abstract
- Rasch analysis was used to examine the validity of the Children's Fear Survey Schedule Dental Subscale (CFSS-DS). Data were collected from parents of children in regular dental care (n=240) and from parents of children referred to a specialized pediatric dental clinic (n=200). The Rasch model is a probabilistic model in which estimations are based on the relationship between person ability and item difficulty, and the present study investigated the validity of the CFSS-DS through analysis of person and item fit, dimensionality, ordering of thresholds, local dependency, and differential item functioning. The results show multidimensionality of the original scale, and an adjusted version consisting of six items with good fit to the model is suggested. The adjusted scale makes interval-level analysis possible, and time efficiency and elimination of previously criticized items argue in favor of the adjusted scale.

Tidskriftsartikel (refereegranskat)abstract
- Traumatic injuries to the primary dentition present special problems and the management is often different as compared with the permanent dentition. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialities were included in the task group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care for management of primary teeth injuries. The IADT cannot and does not guarantee favorable outcomes from strict adherence to the guidelines, but believe that their application can maximize the chances of a positive outcome.

Idiopathic resorption of impacted mesiodentes: a radiographic study
- 2015
-

Tidskriftsartikel (refereegranskat)abstract
- Background: Although a large number of mesiodentes are left in situ, only a few are found in radiographs from epidemiological studies of adult populations. This leads to the development of a hypothesis that mesiodentes may be resorbed and disappear over time. The aim of this study was to radiographically investigate the frequency of resorptions and pathologies in relation to mesiodentes left in situ. Methods: The study population consisted of 44 individuals, with 49 mesiodentes left in situ at an early age. The individuals were 18–38years old when re-examined. The inclusion criteria were that the mesiodentes had been diagnosed in childhood and left in situ, and that each individual was over 18years of age at the time of re-examination. Either digital or analogue intraoral radiographs were used at the re-examination and compared with earlier analogue radiographs. Results: Forty-one per cent of the impacted mesiodentes showed resorptions—from limited to nearly complete resorption. No pathologies in connection to the mesiodentes were found. Conclusion: About half of the mesiodentes examined displayed resorption. No pathologies caused by the mesiodentes were recorded

- Aim: To collect prospective information reported by parents regarding dental traumas occurring in children 6months to 4years of age, furthermore, to collect data on complications from the dental records. Methods: The staff from the child health services distributed a questionnaire at the regular health check-up reviews for a number of age groups, i.e., 6, 12, 18, 24, 30, 36, and 42months of age. The parents were to observe and register factors around dental trauma for the following 6-month period. The questionnaires (138) were returned, irrespective of any trauma having occurred or not. If a child was seeing a dentist (emergency visit), the diagnosis of trauma and later complications were collected from the dental records. Results: There were 35 of 138 children experienced trauma (6–47months of age). The half-year incidence of trauma in children 6months to 4.0years of age was between 12 and 48%. A total of 41 traumatic dental injuries (TDIs) were reported. Of these 24 occurred indoors. The most common reason for trauma was falling accidents. In 24 out of the 41 reported TDIs the children were not seen by a dentist in connection with the trauma. The reason was that the parents thought the trauma did not matter. Conclusions: The high incidence of TDIs reported in toddlers in this study indicates that there is an under-reporting of TDIs in previously reported studies. The research design used in the present study has an advantage and should be tested in further studies. © 2018, European Academy of Paediatric Dentistry.

- AimTo investigate general unintentional injuries (GUI) and traumatic dental injuries (TDI) in relation to behavioral and psychosocial strengths and difficulties among Swedish children aged 0-17 years, and to investigate general unintentional injuries in relation to temperament and socioeconomic status among the same children. Subjects and methodsThe study included 2363 children in four different age cohorts aged 3, 7, 11, and 15 years at the study start. Twelve Public Dental Service clinics in Sweden participated, representing different types of demographic areas, both rural and urban. Data were collected from parents and children through an interview, questionnaires, and dental records. ResultsTwenty-four percentage (24%) of the children had experienced a serious general unintentional injury (GUI) at some point during their lifetime up until 3 months prior to the study start. Children who were regarded by their parents as being injured more often than other children also had occasions with general unintentional injuries to a greater extent. Most general unintentional injuries occurred at home. Children with incidents of general unintentional injuries had occasions with TDI to a greater extent than children without general unintentional injury. Children, whose mothers had 11 years of school/education or less, were involved in more general unintentional injuries during the 3-month period prior to the study start, compared to children of mothers with higher education level. ConclusionsChildren with general unintentional injuries had more traumatic dental injuries. Children who were assessed by their parents as being injured more often than other children also had occasions with general unintentional injuries to a greater extent. Temperament, behavioral and psychosocial strengths and difficulties had different impacts at different ages for experiencing a general unintentional injury.

Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim of the study was to identify individual risk factors for traumatic dental injuries (TDI) among Swedish children aged 0-17 years. The studied risk factors were temperamental reactivity of the child, family structure, parent's country of birth, and the socioeconomic status of the family represented by parental education and occupation. Subjects and methods: The study included 2363 children in four different age cohorts at 12 public dental service clinics in Sweden, representing different types of demographic areas, both rural and urban. Data were collected from parents and children through an interview and questionnaires. Results: The more social and active children in the two older age cohorts showed less occasions of TDI. Having one parent/guardian protected the child from dental injury just as well as two parents/guardians. Parents born outside of the Nordic countries showed children with less TDI. Low parental education was related to more occasions of TDI among the children. Conclusions: This study has increased the knowledge on certain individual risk factors for TDI. To prevent dental injuries, information could be given to families and children at risk.

- Abstract BACKGROUND/AIM: To prevent traumatic dental injuries (TDI), there is a need for vital information. This information could be reached using certain specific variables. The aim of this study, therefore, was to investigate TDI in different age groups, their etiology, and differences by gender, in Swedish children aged 0-17 years. SUBJECTS AND METHODS: The study included 2363 children in four different age cohorts from 12 Public Dental Service clinics in Sweden. The design was a 5-year longitudinal study including yearly clinical examinations, retrospective and prospective data compiled from dental records and interviews regarding TDI. RESULTS: The prevalence for TDI was 37.6% (889) with no gender differences. Boys suffered more injuries during the spring and fall compared to girls. The incidence of 2.8% varied between the age groups where preschool children presented the highest incidence. No changes in prevalence for TDI were found for the years included in the study. The most common reason for TDI was Falling (42.1%). The frequencies for the etiological factors varied between the ages. CONCLUSIONS: The TDI prevalence showed to be stable at a high level in spite of great efforts in Sweden and worldwide to reduce it. Knowledge in why, where, and when TDI appears is therefore essential for dental personnel who will work to reduce TDI.

Ingår i: Archives of Oral Biology. - 0003-9969. ; 155
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: This study aims to validate a methodology for analyzing undecalcified, sound dental enamel proteomics using Liquid Chromatography-Mass Spectrometry (LC-MS). The study evaluates various parameters, including the impact of dental root coverage on protein contamination, the efficacy of protease inhibitors during enamel sample preparation, repeatability of LC-MS measurements on dental enamel, and statistical analysis. The study also assesses the effectiveness of combined trypsin and semi-trypsin searches in Mascot for obtaining additional protein identification data. Design: Sound dental enamel was removed using a wet grinding technique, then digested with trypsin and labeled with TMT prior to LC-MS analysis. The resulting proteomes were matched against the Homo sapiens Swissprot Database, with searches in Mascot performed using both trypsin and semitrypsin. Statistical methods were employed to analyze the data. Results: The study found that covering dental roots with composite during dental enamel microdissection is advisable, while using protease inhibition during microdissection may not be fully supported. The proteomic analyses demonstrated statistical repeatability and reliability, with consistent and reproducible proteomic data obtained from healthy dental enamel. Furthermore, employing both trypsin and semitrypsin searches in Mascot provided additional proteomic information. Conclusions: Overall, this study validates a methodology for analyzing undecalcified, sound dental enamel proteomics using LC-MS, and provides insights into various factors that can affect the quality and reliability of proteomic data. These findings have implications for future studies pursuant to understanding the proteomic mechanisms underlying dental enamel formation and other associated processes.

- Purpose The aim of this study was to explore the potential to profile and distinguish varying clinical severity grades of MIH, compared to normal enamel, using proteomics.Methods Liquid chromatography-mass spectrometry analyses were conducted on enamel samples of extracted teeth, from 11 children and adolescents, spanning an age range of 6-18 years. Enamel powder samples were collected from extracted, third molars (n = 3) and first permanent molars diagnosed with MIH (n = 8). The MIH tooth samples were categorized into subgroups based on clinical severity grade. The data were statistically analyzed using ANOVA and Welch's t test.Results Teeth affected by MIH exhibited a diverse array of proteins, each with different functions related to dental enamel, distinguishing them from their normal enamel counterparts. The application of microdissection combined with LC-MS techniques has revealed the potential to discern unique proteomic profiles among MIH-affected teeth, characterized by varying clinical severity grades. Both analyzed MIH groups displayed consistent trends in the presentation of biological processes, including underabundance of proteins primarily associated with cell organization and biogenesis. Furthermore, proteins linked to cell death were overabundant in both MIH groups.Conclusion Proteomics enabled the detection and differentiation of various proteins across different clinical severity grades of MIH.

- This paper is a review of the clinical findings from my thesis "Pulp survival and hard tissue formation subsequent to dental trauma". Traumatic injuries in children and adolescents are a common problem, and the prevalence of such injuries has increased over the last 10-20 years. The purpose of the present investigations was to evaluate the long-term results following uncomplicated crown fractures and luxations involving subsequent pulp canal obliteration. A total of 241 patients with 545 injured teeth were available for clinical examination, of whom 102 answered a questionnaire and were interviewed before oral examination. In addition, 82 permanent incisors presenting with pulp canal obliteration were followed for a period of 7 to 22 years (mean 16 years). The findings showed little pulpal response to crown fracture and subsequent restorative procedures as long as there was no concomitant periodontal injury (15-year follow-up). Approximately every fourth resin composite filling was rated as unacceptable at clinical examination. The interview showed that half of the individuals were dissatisfied with the color and/or anatomic form of the composite restoration. Pulp canal obliteration was found in all luxation categories, and 69% of the teeth demonstrated yellow crown discoloration. According to the survival curve the 20-year pulp survival rate diagnosed radiographically was 84%. Although the risk of pulp necrosis increased with time, routine endodontic intervention of teeth with ongoing pulp canal obliteration of the root canal did not seem justified.

Tidskriftsartikel (refereegranskat)abstract
- Little long-term data are available on the frequency by which pulp canal obliteration (PCO) subsequent to trauma leads to pulp necrosis (PN). In this study, 82 concussed, subluxated, extruded, laterally luxated, and intruded permanent incisors presenting with PCO were followed for a period of 7 to 22 yr (mean 16 yr). At final clinical examination, 51% of the observed teeth responded normally to electric pulp testing (EPT). An additional 40% of the teeth although not responding to EPT were clinically and radiographically within normal limits. Yellow discoloration was a frequent finding. During the observation period, periapical bone lesions suggesting PN developed in seven teeth (8.5%). Twenty-yr pulp survival rate was 84%, as determined from life-table calculations. There was no higher frequency of PN in obliterated teeth subjected to caries, new trauma, orthodontic treatment, or complete crown coverage than intact teeth. Although the incidence of PN in teeth displaying PCO seems to increase over the course of time, prophylactic endodontic intervention on a routine basis does not seem justified.

- The am of this study was to evaluate subjective aspects from questionnaires dealing with dental trauma by applying different computerized inductive techniques within the field of artificial intelligence to questionnaires consisting of descriptive variables and of questions reflecting functional, personal, and social effects of patients' oral situation following dental trauma. As the methodology used is new to many readers in odontologic sciences, a detailed description of both the processes and the terminology is given. Utilizing a neural network as a first step in an analysis of data showed if relations existed in the training set, but the network could not make the relations explicit, so other methods, inductive methods, had to be applied. Inductive methods have the potential constructing rules from a set of examples. The rules combined with domain knowledge can reveal relations between the variables. It can be concluded that the usage of methods based on artificial intelligence can greatly improve explanatory value and make knowledge in databases explicit.

Tidskriftsartikel (refereegranskat)abstract
- Dental trauma in children and adolescents is a common problem, and the prevalence of these injuries has increased in the last 10-20 years. A dental injury should always be considered an emergency and, thus, be treated immediately to relieve pain, facilitate reduction of displaced teeth, reconstruct lost hard tissue, and improve prognosis. Rational therapy depends upon a correct diagnosis, which can be achieved with the aid of various examination techniques. It must be understood that an incomplete examination can lead to inaccurate diagnosis and less successful treatment. Good knowledge of traumatology and models of treatments can also reduce stress and anxiety for both the patient and the dental team. Knowledge-based Systems (KBS) are a practical implementation of Artificial Intelligence. In complex domains which humans find difficult to understand, KBS can assist in making decisions and can also add knowledge. The aim of this paper is to describe the structure of a knowledge-based system for structured examination, diagnosis and therapy for traumatised primary and permanent teeth. A commercially available program was used as developmental tool for the programming (XpertRule, Attar, London, UK). The paper presents a model for a computerised decision support system for traumatology.

- OBJECTIVES: The aim of the present study was to investigate pulp healing responses following crown fracture with and without pulp exposure as well as with and without associated luxation injury and in relation to stage of root development. PATIENT MATERIAL AND METHODS: The long-term prognosis was examined for 455 permanent teeth with crown fractures, 352 (246 with associated luxation injury) without pulpal involvement and 103 (69 with associated luxation injury) with pulp exposures. Initial treatment for all patients was provided by on-call oral surgeons at the emergency service, University Hospital (Rigshospitalet), Copenhagen. In fractures without pulpal involvement, dentin was covered by a hard-setting calcium hydroxide cement (Dycal), marginal enamel acid-etched (phosphoric acid gel), then covered with a temporary crown and bridge material. In the case of pulp exposure, pulp capping or partial pulpotomy was performed. Thereafter treatment was identical to the first group. Patients were then referred to their own dentist for resin composite restoration. RESULTS: Patients were monitored for normal pulp healing or healing complications for up to 17 years after injury (x = 2.3 years, range 0.2-17.0 years, SD + 2.7). Pulp healing was registered and classified into pulp survival with no radiographic change (PS), pulp canal obliteration (PCO) and pulp necrosis (PN). Healing was related to the following clinical factors: stage of root development at the time of injury, associated damage to the periodontium at time of injury (luxation) and time interval from injury until initial treatment. Crown fractures with or without pulp exposure and no concomitant luxation injury showed PS in 99%, PCO in 1% and PN in 0%. Crown fractures with concomitant luxation showed PS in 70%, PCO in 5% and PN in 25%. An associated damage to the periodontal ligament significantly increased the likelihood of pulp necrosis from 0% to 28% (P < 0.001) in teeth with only enamel and dentin exposure and from 0% to 14% (P < 0.001) in teeth with pulp exposure. CONCLUSIONS: In the case of concomitant luxation injuries, the stage of root development played an important role in the risk of pulp necrosis after crown fracture. However, the primary factor related to pulp healing events after crown fracture appears to be compromised pulp circulation due to concomitant luxation injuries.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was to investigate histopathological changes in primary teeth following trauma, and to look for possible correlations between the morphology of pulpal calcification and clinical findings. The material consisted of 123 primary teeth from 98 Danish children aged 9-108 months (mean age 33.5 +/- 19.7 months) at the time of injury. The specimens were analyzed by means of light and scanning and transmission electron microscopy. Data from the clinical investigation and from predetermined ranked parameters from the histological analysis were processed in a computerized inductive analysis program. The results, describing patterns of co-variation, are presented as a decision tree. The most common diagnosis was intrusion luxation (54%). In 41% of all teeth, the degree of obliteration was less than 1/4 of the pulpal lumen. In most cases (79%), no denticles were visible. When present, 80% of the denticles had a bone-like appearance. Tissues occluding the pulpal lumen were either dentin-like (49%), bone-like (19%), or fibrotic (9%). It could be concluded that these varying responses could not be correlated with explicit clinical diagnoses. However, in certain combinations, histological parameters could be correlated to clinical findings.

- The aim of this study was to obtain detailed information about adults who suffered trauma to the teeth as children. A total of 102 patients took part. The patients answered a questionnaire and were interviewed before the oral examination. Thirty-nine per cent of the patients reported dissatisfaction either with the color and/or anatomic form of the traumatized teeth or reconstruction. Most of the individuals did not remember having received any information about prognosis for the traumatized teeth. Twenty-one per cent of the patients remembered pain during treatment, and 25% remembered only the behavior and attitudes of the dental team. It can be concluded that all dental treatment in children with traumatized teeth must be carried out as painlessly as possible, and the dental team should minimize discomfort during the treatment. Good knowledge about traumatology and management can reduce stress and anxiety for both the patient and the dental team.

- Preterm children with very low birth weight suffer from several neonatal and postnatal complications that may affect the mineralization of teeth. Clinical and morphological studies have shown enamel aberrations in teeth from preterm children. In this study, the chemical composition in enamel and dentin was compared in primary teeth from preterm children and full-term children, and the relationship between the chemical composition and the morphological appearance was investigated. Enamel and dentin in 17 exfoliated primary teeth, from 14 children with a gestational age below 29 wk, were investigated and compared with 36 exfoliated primary teeth from full-term children, using X-ray microanalyses (XRMA). In comparison with the teeth from the controls, the teeth from preterm children had a higher relative value of carbon (C), a lower relative value of calcium (Ca), a lower ratio of calcium/phosphorus (Ca/P) and a lower ratio of Ca/C throughout the outer part of the enamel. In dentin, the relative values for P were higher, and Ca/P ratio was lower, at the dentin-pulp junction. The Ca/P ratio indicated normal hydroxyapatite in the crystals in enamel and dentin. The lower ratio of Ca/C in the bulk and outer part of the enamel indicated more porous enamel.

- It has been shown that children born extremely preterm (EPT) often suffer from medical complications and growth restrictions in early childhood. Catchup growth diminishes these effects but the children are known to have lower weight, height, and head circumference as school children. Effects on enamel development have been shown. How this affects the dento-alveolar outcome during adolescence is not known. Forty EPT children with a gestational age (GA) of less than 29 weeks, at 12-16 years of age, and matched healthy controls born at term, with a GA of 37-43 weeks, were examined. Data from the clinical examination, dental casts, and bitewing radiographs were collected and compared. Malocclusion was noted, and dento-alveolar length, width, palatal height, and mesio-distal tooth width were measured. Medical diagnoses, neurological, and neuropsychiatric disturbances were noted at the time of the survey. The two groups were compared with an epidemiological normal reference material. The results showed no differences between the controls and reference material. Angle Class II was the most frequent malocclusion associated with morbidity, neurological, and neuropsychiatric disturbances, followed by deep bite and overjet. Three or more malocclusions were almost twice as common among the EPT children compared with the controls. Significantly smaller incisors, canines, and first molars were found. In summary, the EPT children, during adolescence, had medical aberrations as well as dento-alveolar effects opposed to the healthy children born at term. Dentists should be aware of this and treatment plans should be made in due time.

- BACKGROUND: Preterm children with very low birth weight suffer from several neonatal and post-natal complications that may affect the mineralization of the teeth. Clinical studies have shown enamel aberrations in both dentitions. AIMS: The aims of this study were to describe enamel histo-morphology in primary teeth, and investigate the relationship between medical history and morphological appearance. DESIGN: Dental enamels in 44 exfoliated primary teeth, from 14 children with a gestational age below 29 weeks and with a very low birth weight, were investigated, using polarized light microscopy (POLMI) and under a scanning electron microscope (SEM). RESULTS: The neonatal line was found in 1/3 of the sections located coronally of the crown. In the post-natal enamel, 31 teeth showed a degree of porosity higher than 5% with a varying extension. More than half of the teeth showed one or more increment lines. The SEM analysis confirmed the POLMI findings with irregular prisms covered with a structure-less film. CONCLUSIONS: Enamel from primary teeth of preterm children was found to have a high frequency of mineralization disturbances found in POLMI and SEM. The morphological features of the enamel from preterm children do not reflect the disturbances on general growth and development occurred during the neonatal period.

- The primary teeth start to mineralize in utero and continue development and maturation during the first year of life.The aim of this study was to investigate the concentrations of some elements, C, F, Na, Mg, Cl, K and Sr, by secondary ion mass spectrometry (SIMS) in human primary incisors at different stages of mineralization.The teeth derived from an autopsy material from children who had died in sudden infant death.The buccal enamel of specimens from the ages 1, 2, 3, 4, 6 and 19 months, respectively, was analyzed. It was evident that posteruptive effects play an important role in composition of the outermost parts of the enamel. Before the tooth erupts, the concentrations of the elements vary with the maturation grade of the mineralization in the enamel. Sodium was the element with the highest concentration of the measured elements and chlorine was the element of lowest concentration.The 19 month old specimen, considered as the only mature and erupted tooth, showed to differ from the other specimens.The concentration of fluorine, in the 19 month old specimen's outermost surface, is readily seen higher compared with the other specimens at this depth zone. In the 19 month old specimen the concentration of carbon is lower. Potassium, sodium and chlorine have higher concentrations, in general, in the 19 month old specimen compared with the immature specimens. The thickness of the enamel during mineralization was calculated from data from SIMS.The thickness of the buccal enamel of primary incisors seemed to be fully developed between 3-4 months after birth, reaching a thickness of 350-400 microm.
