- OBJECTIVES: To assess the success rate of spontaneous space closure after extraction of the first permanent molar (FPM) in the maxilla and the mandible, and to identify the factors that make spontaneous space closure most favorable in each.MATERIALS AND METHODS: A retrospective records-based cohort study was conducted through a search of the database of the Public Dental Service, Stockholm County Council, Stockholm, for young adults born between 2000 and 2001, who underwent extraction of one or more FPM between 2006 and 2016. A total of 995 extracted teeth were identified, of which 203 teeth in 155 patients met the inclusion criteria.RESULTS: Of the 203 extracted teeth, 166 (81.8%) did not receive any orthodontic treatment. The success rate for space closure in orthodontically treated patients was 91.9%. The success rate for spontaneous space closure was 84.3%. All unsuccessful spontaneous space closure in the maxilla occurred in patients older than 12 years. The dental developmental stage of the second permanent molar (SPM) had a statistically significant association with spontaneous space closure in the mandible (P < .001).CONCLUSIONS: The success rate of spontaneous space closure was high (84.3%) and was higher in the maxilla (94.1%) than the mandible (74.1%). Age at time of extraction and dental developmental stage of the SPM were significant factors for successful spontaneous space closure in the maxilla and mandible, respectively.

Do Different Maxillary Expansion Appliances Influence the Outcomes of the Treatment?
- 2018
-
In: European Journal of Orthodontics. - : Oxford University Press. - 0141-5387 .- 1460-2210. ; 40:1, s. 97-106
-
Research review (peer-reviewed)abstract
- Background and objectives: There is no consensus in the literature regarding which rapid maxillary expansion (RME) design or activation rate benefits the patients the most. Therefore, the primary aim of this systematic review was to see whether there is a difference in the skeletal and dentoalveolar effects of different RME appliances in children and growing adolescents. The secondary aim was to see whether these effects are different when using different activation protocols for these appliances. Data collection and analysis: The search was done in three databases (PubMed, Cochrane Library, and Web of Science). The following inclusion criteria were used: randomized controlled trial, prospective controlled studies, 15 or more patients in each study, human subjects up to 18 years of age, and RME effects had to be assessed by computed tomography/cone beam computed tomography. Study appraisal and synthesis methods: Quality of the methodology was classified according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines as high, moderate, or low. Results: The search resulted in 145 titles and abstracts; 109 of them were excluded based on pre-established criteria. Thirty-six full-text articles were assessed for eligibility and 18 of which satisfied the inclusion criteria. Finally, seven articles were deemed eligible for full inclusion and revealed that all appliances and protocols showed significant expansion in the mid-palatal suture. No evidence was found for the cause of dental tipping. Limitations: In this systematic review, having different age groups in each study and using different anatomical landmarks and outcome measures for assessing the skeletal and dental effects made it difficult to conduct a meta-analysis. Conclusions: There is moderate evidence that all designs produce significant expansion at the mid-palatal suture. However, lack of studies comparing appliances and protocols has been found. Finally, no evidence-based conclusions could be drawn about the appliance effect on teeth tipping.

- OBJECTIVE: and P-CPQ, and to evaluate the impact on agreement of oral health including malocclusion and background characteristics (dental fear, family situation, gender of informant).MATERIAL AND METHODS: and P-CPQ separately in connection with a clinical examination.RESULTS: The participants comprised 247 child-parent pairs: 116 (47%) boys, 131 (53%) girls, 166 (67%) mothers and 81 (33%) fathers. The agreement between the child and parental ratings of the children's OHRQoL was low, with an ICC of 0.22 (95% CI: 0.04-0.37) for the total scale.CONCLUSIONS: There was a low agreement between children's and parents' answers. For best care, it is advisable to consider perceptions of both children and parents because they can complement each other in estimating the child's OHRQoL.

Malocclusions and quality of life : cross-sectional and longitudinal studies in children
- 2015
-
Doctoral thesis (other academic/artistic)abstract
- There are few longitudinal studies of the prevalence of malocclusionsand possible self-correction of malocclusions during the developmentof the dentition. Early intervention might be unnecessary if self-correction of the malocclusion occurs during the transition from theprimary to the permanent dentition. Most studies are cross-sectionaland in those of longitudinal design, the results are inconsistent anddifficult to interpret.Malocclusions may or may not influence the quality of life inchildren and adolescents. Thus, evaluations of the influence ofdifferent malocclusions on quality of life will certainly underpin abroader understanding and knowledge about how malocclusionsaffect the daily life of young patients. This information may also beimportant when it comes to assessing the most appropriate time forstarting orthodontic treatment, not only from a professional pointof view, but also, most importantly, from the patients’ perspective.The overall aim of this thesis was therefore to evaluate theprevalence of malocclusions, and to document changes occurringduring the development of the dentition, from the primary dentitionstage at age 3, through the mixed dentition at age 7, to the earlypermanent dentition at age 11.5 years. Further aims were to reviewthe current state of knowledge about the impact of malocclusionson oral health related quality of life (OHRQoL) and to investigatehow malocclusions affect the quality of life in a cohort of children,aged 11.5 years, whose dental care is provided by the Swedish PublicDental Service.

Malocclusions in children at 3 and 7 years of age : a longitudinal study
- 2013
-
In: European Journal of Orthodontics. - : Oxford University Press. - 0141-5387 .- 1460-2210. ; 35:1, s. 131-137
-
Journal article (peer-reviewed)abstract
- The aim of this longitudinal study was to compare the prevalence of malocclusion at ages 3 and 7 years in a sample of children, exploring the hypothesis that prevalence of malocclusion is higher at 3 than at 7 years of age and may be influenced by sucking habits. The study sample comprised 386 children (199 girls and 187 boys), aged 3 years at study start, sourced from three Public Dental Service clinics in Sweden. Malocclusion was diagnosed by clinical examination, using a specific protocol. Data on allergy, traumatic injuries, sucking habits, and breathing pattern including nocturnal breathing disturbances were obtained by means of a questionnaire answered by child and parent in conjunction with the initial and final clinical examination. The overall prevalence of malocclusion decreased significantly, from 70 to 58% (P < 0.0001): predominantly anterior open bite, excessive overjet, and Class III malocclusion. Although high rates of spontaneous correction were also noted for deep bite, Class II malocclusion and posterior and anterior crossbites, new cases developed at almost the same rate; thus, the prevalence was unchanged at the end of the observation period. Anterior open bite and posterior crossbite were the only conditions showing significant associations with sucking habits. The results confirm the hypothesis of higher prevalence of malocclusion at 3 years of age and clearly support the strategy of deferring orthodontic correction of malocclusion until the mixed dentition stage.

Oral health-related quality-of-life among children in Swedish dental care : The impact from malocclusions or orthodontic treatment need
- 2016
-
In: Acta Odontologica Scandinavica. - : Taylor & Francis. - 0001-6357 .- 1502-3850. ; 74:2, s. 127-133

Journal article (peer-reviewed)abstract
- Objectives: To describe oral health-related quality-of-life (OHRQoL) and the impact of malocclusions or orthodontic treatment need in a cohort of children in Swedish dental care, using the Swedish version of the Child Perceptions Questionnaire-Impact Short Form (CPQ(11-14)-ISF:16).Subjects and methods: Two hundred and fifty-seven children (mean age = 11.5 years, SD = 0.8, range = 9.8-13.5 years) completed the CPQ(11-14)-ISF:16 in conjunction with a clinical examination. In addition to malocclusions and orthodontic treatment need (based on the Index of Orthodontic Treatment Need-Dental Health Component), possible confounders (caries, enamel defects, dental trauma, headache and socio-economic markers) were recorded. Children also rated their own dental fear on the Children's Fear Survey Schedule-Dental Sub-scale (CFSS-DS).Results: The mean total CPQ(11-14)-ISF:16 score was 9.31. The logistic regression analyses revealed an impact of orthodontic treatment need on OHRQoL (CPQ), but no clear association between higher severity and higher impact on OHRQoL was seen. Dental fear and headache appeared to discriminate for poorer OHRQoL. No impact from caries, enamel defects, dental trauma, or socio-economic markers was revealed.Conclusions: This cohort of children reported good self-perceived OHRQoL. Effects on OHRQoL from malocclusions or orthodontic treatment need were limited and inconsistent. Dental fear and headache were found to be more distinct impact factors on OHRQoL than were malocclusions or orthodontic treatment need.

Journal article (peer-reviewed)abstract
- Objective: To follow a group of children from primary to early permanent dentition and determine the prevalence, self-correction, and new development of malocclusions; the need for orthodontic treatment; and the possible influences of habits, breathing disturbances, and allergies.Materials and Methods: Two hundred and seventy-seven children were followed at 3, 7, and 11.5 years of age. Malocclusions and orthodontic treatment need were determined by clinical examinations. Data on sucking habits, breathing disturbances, allergies, dental trauma, and orthodontic treatments were collected from a questionnaire and dental records.Results: Malocclusions were found in 71% of participants at 3 years of age, 56% at 7 years of age, and 71% at 11.5 years of age. Self-correction was noted for anterior open bite, sagittal malocclusions, and posterior crossbite, while deep bite developed. A high number of contact point displacements and spacings contributed to the prevalence of malocclusion rate of 71% at 11.5 years. Severe or extreme orthodontic treatment need was apparent in 22%. Habits, allergies, or breathing disturbances found at 3 years of age had no associations with malocclusions at 11.5 years of age.Conclusions: This sample revealed a significant percentage of malocclusions and orthodontic treatment need. A substantial number of self-corrections and establishment of new malocclusions occurred during the transition from primary to early permanent dentition.

In: Swedish Dental Journal. - : Swedish Dental Association. - 0347-9994. ; 34:1, s. 35-42
-
Journal article (peer-reviewed)abstract
- The aim of the present study was to evaluate the prevalence of malocclusion traits and sucking habits among 3-year-old children. A sample of 457 3-year-old children (234 girls and 223 boys) was obtained from three Public Dental Health clinics in Orebro County Council, Sweden. Data from clinical examination and a questionnaire were used to determine malocclusion traits, sucking habits, snoring and breathing pattern including nocturnal breathing disturbances. The results showed that 70% had one or more malocclusion traits at 3 years of age. The most common malocclusion traits were anterior open bite (50%), Class II occlusion (26%), increased overjet (23%) and posterior crossbite (19%). The prevalence of sucking habit was 66% and dummy sucking was dominating and in connection with more malocclusion traits than finger/thumb sucking. A significant association was found between the sucking habits and the most prevalent malocclusions, anterior open bite, Class II occlusion, increased overjet and posterior crossbite. In conclusion, the prevalence of malocclusion traits in 3-year-old children was high. Sucking habits was highly prevalent and dummy sucking resulted in more malocclusion traits than finger/thumb sucking did.

Research review (peer-reviewed)abstract
- Background: Among child and adolescent patients, persistent but untreated malocclusions may or may not have psychological and social impacts on the individual's quality of life. Objectives: To gain knowledge of malocclusions and its impact on oral health-related quality of life (OHRQOL), we conducted a systematic review of quantitative studies for evidence regarding the influence of malocclusions on OHRQOL in children and adolescents. Materials and methods: Five databases (MEDLINE via PubMed, EMBASE, Psychinfo, CINAHL, and the Cochrane Library) were searched using specified indexing terms. The following inclusion criteria were used: child or adolescent study population; healthy study participants without syndromes such as cleft lip/palate or severe illness; no previous or ongoing orthodontic treatment among participants; a focus on malocclusions and quality of life; controlled or subgrouped according to malocclusions/no malocclusions; malocclusions and/or orthodontic treatment need assessed by professionals using standardized measures; self-assessed OHRQOL estimated using validated questionnaire instruments; full-text articles written in English or Scandinavian languages. Quality of evidence was classified according to GRADE guidelines as high, moderate, or low. Results: The search produced 1142 titles and abstracts. Based on pre-established criteria, the full-text versions of 70 articles were obtained, 22 of which satisfied the inclusion criteria. After data extraction and interpretation, six publications were deemed eligible for full inclusion. All six were of cross-sectional design, and the quality of evidence was high in four cases and moderate in the remaining two. The four studies with a high level of quality reported that anterior malocclusion had a negative impact on OHRQOL, and the two with a moderate level of quality reported that increased orthodontic treatment need had a negative impact on OHRQOL. Conclusion: The scientific evidence was considered strong since four studies with high level of quality reported that malocclusions have negative effects on OHRQOL, predominantly in the dimensions of emotional and social wellbeing.
