- Epidemiological data reveal that the prevalence of dental caries in western countries has decreased in recent decades. The aim of this study was to investigate how dentists and dental hygienists assess dental caries lesions in bite-wing radiographs between 1983 and 2003. All dentists and dental hygienists in Public Dental Health in Uppsala County were offered to take part in the study. The participants assessed manifest and initial caries lesions in eight bite-wing radiographs from three patients individually. An X-ray viewer and binoculars were used. The assessments were repeated in the same radiographs every five years, a total of five times, between 1983 and 2003. In the different test occasions 80-103 dentists and 11-48 dental hygienists participated. The registration of dental caries changed between 1983 and 2003. The number of manifest lesions registered by dentists decreased between 1983 and 1988, but were stable after 1988. Dental hygienists showed no changes in the registration of manifest lesions during the study. Initial lesions registered by dentists and dental hygienists increased between 1988 and 1998. Assessments of initial caries lesions displayed a wider range than manifest lesions. Increasing age and more years in the profession resulted in fewer registered initial caries lesions. Dental hygienists had a tendency to register less caries than dentists. In conclusion, the result of the study indicate that inclusion of initial caries lesions in epidemiological reports should lead to a reduction in reliability. The changes in assessments of manifest caries lesions that took place in the 19805s should be considered when epidemiological data are evaluated.

- Oral mucoceles can be divided in two different forms, extravasation and retention cysts. The aim of this study was to identify the frequency of each form, sex- and age distribution, location, recurrences, referent and the differences between the two forms. A total of three-hundred-five cases were retrieved from the Department of Oral Pathology at the Institution of Odontology, The Sahlgrenska Academy at Göteborg University between 1993 and 2003. Seven referrals were disregarded because there was insufficient information, leaving 298 cases for this study. In relation to other studies, our study investigated a larger number of cases. Extravasation cysts were the most common type (258 cases). There was a slight predominance among women (55%) and the most frequent location was the lower lip (71%). 84% occurred between the ages of 0 and 40 years with peak incidence in the second decade (34%). 62% of the referrals came from specialists, 28% from general practitioners, and 10% from the Department of Oral Medicine. Retention cysts were not found as frequently as extravasation cysts (40 cases) and the occurrence in women was also a bit higher (58%). We found a more even distribution regarding age and location. The most common locations were floor of the mouth (25%), cheek (20%), and lower lip (18%). They occurred more often between the ages of 11 and 30 (31%), and between 50 and 80 (50%). 75% of the referrals came from specialists, 15% from general practitioners,and 10% from the Department of Oral Medicine. Recurrences were unusual for both cyst types. 17 cases of extravasation cysts were reported as recurrences and one case of retention cyst.

Impaired jaw function and eating difficulties in Whiplash-associated disorders
- 2008
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 32:4, s. 171-177
-
Tidskriftsartikel (refereegranskat)abstract
- Eating requires mouth opening, biting, chewing and swallowing and should be performed without dysfunction or pain. Previous studies have shown that jaw opening-closing movements are the result of coordinated activation of both jaw and neck muscles, with simultaneous movements in the temporomandibular, atlanto-occipital and cervical spine joints. Consequently, it can be assumed that pain or dysfunction in any of the three joint systems involved could impair jaw activities. In fact, recent findings support this hypothesis by showing an association between neck injury and reduced amplitudes, speed and coordination of integrated jaw-neck movements. This study investigated the possible association between neck injury and disturbed eating behaviour. Fifty Whiplash-associated disorders (WAD) patients with pain and dysfunction in the jaw-face region and 50 healthy age- and sex-matched controls without any history of neck injury participated in the study. All participants were assessed by a questionnaire, which contained 26 items about eating behaviour, jaw pain and dysfunction. For the WAD group there were significant differences in jaw pain and dysfunction and eating behaviour before and after the accident, but no significant differences between WAD before and healthy. The healthy and the WAD group before the accident reported no or few symptoms. The WAD patients after the accident reported pain and dysfunction during mouth opening, biting, chewing, swallowing and yawning and felt fatigue, stiffness and numbness in the jaw-face region. In addition, a majority also reported avoiding tough food, big pieces of food, and taking breaks during meals. Altogether, these observations suggest an association between neck injury and disturbed jaw function and therefore impaired eating behaviour. A clinical implication is that examination of jaw function should be recommended as part of the assessment and rehabilitation of WAD patients.

Tidskriftsartikel (refereegranskat)abstract
- In 1999 a new law in Sweden granted people receiving a certain level of supportive care from the community the right to receive a free, in-home oral health assessment. Subsequent appraisal has disclosed that far from all eligible people, especially those living at home, have undergone such an assessment. Of fundamental importance to the success of this scheme is the active involvement of case managers in identifying those who are eligible for assessment. The aim of this study was to investigate case managers' knowledge of and attitudes to the oral health of their clients and the initiatives they take to ensure that dependent elderly and disabled persons living at home have access to oral health care. In qualitative in-depth interviews, 24 case managers from three Swedish counties were questioned about their perceptions of oral health care for their clients. The transcribed text was analysed by manifest and latent qualitative content analysis. The manifest analysis was based on the three content areas knowledge, attitudes and initiatives. During this process a theme emerged which disclosed the case managers' perceptions of their role in oral health care among elderly and disabled persons, a latent analysis. The case managers' age, education, experience and breadth of responsibilities varied. Their knowledge of the 1999 law was limited. In general there were no procedures in place to ensure that the oral assessments were undertaken and that records were kept. The case managers considered that they should not be responsible, although they could not suggest a more appropriate instance. The potential role of regular oral health assessment in prevention of oral diseases was not discussed at all in the interviews. The current systems for monitoring oral health are tailored primarily to institutionalised care. In future many more dependent people will continue to live at home with support from community home care assistants and relatives. It is important that oral health care activities, as well as research, are modified accordingly.

Morphology and chemical composition of dentin in permanent first molars with the diagnose MIH.
- 2007
-
Ingår i: Swedish dental journal. - 0347-9994. ; 31:4, s. 155-64
-
Tidskriftsartikel (refereegranskat)abstract
- The purpose of this investigation was to study the morphology and distribution of some inorganic elements in dentin in first permanent molars from children with Molar-Incisor Hypomineralization (MIH). Sixty four tooth sections from thirty two children were examined in polarized light. Fifteen representative sections were selected for SEM/XRMA analysis; 5 were used for SEM analysis and 10 for XRMA analysis. No morphological changes in the dentin were revealed in polarized light microscopy (PLM). However, in all but two sections interglobular dentin was found. The SEM analyzes confirmed the findings of the PLM with no structural changes to be found in the dentin. The XRMA results showed a difference in the concentration of elements between dentin below normal and dentin below carious or hypomineralized enamel. Elements related to organic matter appeared with higher values in dentin below hypomineralized and carious enamel. The morphological and chemical findings in dentin below hypomineralized enamel imply that the odontoblasts are not affected in cases of MIH, but may be affected by hypocalcemia, reflected by the presence of interglobular dentin.

Dental digital radiography : a survey of quality aspects
- 2005
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 29:2, s. 81-87
-
Tidskriftsartikel (refereegranskat)abstract
- The aim was to evaluate the experiences of Swedish general dental practitioners (GDPs) with digital radiography and their opinion on the same, particularly regarding quality issues. A letter was sent to all GDPs in private care in Region Skåne, Sweden, asking whether they used digital radiography (n=513). The response rate was 79%. The number of private GDPs who replied that they used digital radiography was 106. The Public Dental Service in Region Skåne listed 33 GDPs who worked with digital radiography. Based on these answers, a questionnaire was sent to the GDPs working with digital radiography (n=139). The questionnaire comprised 27 questions about the dentists, the system of intra-oral digital radiography, and the GDPs’ experiences of and opinions on issues regarding image quality and quality control. The response rate to the questionnaire was 94%. Almost all, 92%, worked with charge-coupled device (CCD) and complementary metal oxide semiconductor (CMOS) sensors. Most GDPs were satisfied with their digital radiographic system. The majority (65%) experienced problems. Detector failure and trouble with the software were common. The GDPs wrote that they used lower exposure times in digital radiography than traditional film radiography. The estimated reduction in exposure time was said to be between 51% and 75%. Thirtyfive per cent continued to use film parallel with digital radiography. The answers indicated that less than half of the equipment (40%) underwent quality control. Quality controls, when conducted, were undertaken once or twice a year, mainly by technicians from the companies that had sold the digital equipment. Based on the results of the questionnaire, there seems to be a need to improve the maintenance and the quality of digital radiography. It is also important that the GDPs become more aware of the problems that can occur when a new technique is introduced and that they develop the skills to handle these problems.

Can orthodontic treatment improve mastication? A controlled, prospective and longitudinal study
- 2009
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 33:2, s. 59-65

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To prospectively and longitudinally evaluate the self-perceived masticatory ability and the tested masticatory efficiency in orthodontically treated and untreated groups. DESIGN: Prospective observational cohort. SUBJECTS AND METHODS: Three groups of age matched adolescent girls were included. Sixty-five Class II subjects received orthodontic treatment fixed appliance treatment (Orthodontic group), 58 subjects were orthodontically untreated (Class II group) and 60 subjects had a normal occlusion (Normal group).The self-perceived masticatory ability was assessed on a visual analogue scale while the masticatory efficiency was evaluated with a masticatory efficiency test using round silicon tablets. Registrations were performed at the start and after two years when all subjects in the Orthodontic group had finished orthodontic treatment. RESULTS: Over the two-year period the self-perceived masticatory ability increased significantly in the Orthodontic group. After treatment, the Orthodontic group perceived their masticatory ability as high as the Normal group did. The masticatory efficiency increased significantly, during the two years, in all three groups. However,the normal occlusion group presented a significantly better masticatory efficiency than both the Orthodontic group and the Class II group on both registrations. CONCLUSIONS: Orthodontic treatment was beneficial for the self-perceived masticatory ability. The masticatory efficiency increases with age during adolescence. Normal occlusion subjects had a better masticatory efficiency than subjects with orthodontically treated as well as untreated Class II malocclusion.

Chlorhexidine-containing Glass Ionomer Cement. A Clinical Investigation on the Fissure Caries Inhibiting Effect in First Permanent Molars
- 2005
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 29:3, s. 89-96
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Glass ionomer cement with addition of chlorhexidine used as a varnish on tooth surfaces has been shown to reduce the number of inter-proximal mutans streptococci (ms). The effect of a single application of such a varnish containing 2.5% chlorhexidine on occlusal caries development of the first permanent molars on 6-year-old children in a high caries incidence area was investigated. The children were examined according to WHO criteria and 262 children with 2 caries free contralateral molars were selected for treatment. Salivary ms samples were collected using the Strip-mutans (SM) method. After brushing the occlusal surfaces with a toothbrush and pumice in water slurry, rinsing and drying with a cotton roll, glass ionomer cement containing chlorhexidine (GI-CHX) and glass ionomer (GI) were applied randomly with a micro brush and the varnish was covered with occlusal wax. At baseline, the mean defs was 18.18 and DMFS was 0.25 and after one year 18.24 and 0.83 respectively. The salivary ms scores were high or very high (SM 2 and 3) in 85.6% at baseline. At the one-year follow up, the GI-CHX and GI materials could not be detected in the fissures. Also, a large number of fissure sealants had been placed in the molars outside the study protocol; thus 4% of the GI-CHX and GI, and 70% of the untreated were sealed at year one. Overall, there was no significant difference between the caries-reducing effect of GI-CHX and GI, but a trend towards a higher effect was seen for GI-CHX. Excluding the sealed molars the reduction was 74% in the GI-CHX-group, and 71% in the GI-group. Conclusion: Addition of 2.5% chlorhexidine to glass ionomer did not seem to increase the caries-reducing effect of the varnish in this high caries incidence population.

Oral health of individuals aged 3-80 years in Jönköping, Sweden during 30 years (1973-2003) : I. Review of findings on dental care habits and knowledge of oral health
- 2005
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 29:4, s. 125-138

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present study was to compare data on dental care habits and knowledge of oral health in four cross-sectional epidemiological studies carried out in 1973,1983,1993, and 2003. The 1973 study constituted a random sample of 1,000 individuals evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, and 70 years. The same age groups with addition of a group of 80-year-olds were included in the 1983, 1993 and 2003 studies, which comprised 1,104, 1,078, and 987 individuals, respectively. A questionnaire about dental care habits and knowledge of oral health was used in connection with a clinical and radiographic examination. The same questions were used in all the four studies. An addition to the 1993 and 2003 investigations were questions concerning ethnic background. In 2003 approximately 90-95 per cent of all individuals were visiting the dentist on a regular basis every or every second year. The 30- and 40-yea r-olds, however, did not visit a dentist as regularly in 2003 as in 1993. In these age groups 21-24 per cent of the individuals, respectively, reported that they had not visited a dentist in the last 2 years. Almost all children 3-15 years old received their dental care within the Public Dental Service (PDS). During the period 1973-2003 an increase in percentage of individuals aged 20-50 years treated by the PDS was seen compared to private practice, while among 60-80 year-olds there were only minor changes. Most so-year-olds and older received their dental care by private practitioners. About 70-80 per cent of all adults in 2003 were enrolled in a recall system on the dentist's initiative while in 1973 most appointments were based on the patient's own initiative. The number of individuals who were frightened, 5-17 per cent, or felt discomfort at the prospect of an appointment with the dentist was more or less the same during the whole period. The knowledge of the etiology of dental diseases did not changed much between 1973 and 2003. The frequency of toothbrushing increased since 1973 and in 2003 more than 90 per cent of all individuals brushed their teeth twice or once a day. The use of dental floss and toothpicks decreased in 2003 compared to 1983 and 1993. Almost all individuals in 2003 used fluoride toothpaste. It was obvious that the dental team constituted the main source of dental health information. For the age groups 20 and 30 years information from friends and relatives was also important. In the age groups 3-20 years up to 45 per cent of the individuals were consuming soft drinks every day or several times a week.
