- The aim was to study the prevalence and distribution of number of teeth, number of intact and decayed teeth and prevalence and distribution of removable dentures and periodontal disease over 25 years 1983-2008. Two cross-sectional studies (EpiWux) were performed in the County of Dalarna, Sweden in 1983 and 2008. In the 1983 study a random sample of 1012 individuals were invited to participate in this epidemiological and clinical study and 1440 individuals in 2008. A total number of 1695 individuals, stratified into geographical areas (rural and urban areas), in the age groups 35, 50,65 and 75 answered a questionnaire and were also clinically and radiographically examined. The number of edentulous individuals decreased from 15% in 1983 to 3 % in 2008. Number of teeth increased from 22.7 in 1983 to 24.2 in 2008 and decayed surfaces per tooth showed a three-time reduction over this period of time. As a consequence of better oral status the prevalence of complete removable dentures in both jaws decreased from 15 % in 1983 to 2 % in 2008. Individuals with moderate periodontitis decreased from 45 % in 1983 to 16 % in 2008. Conclusion: Covering a period of 25 years the present study can report dramatic improvements in all aspects of dental status that were investigated. This is encouraging for dental care professionals, but will not necessarily lead to less demand for dental care in the future as the population is aging with a substantial increase in number of teeth.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to compare the quality of fixed partial dentures (FPDs) made in a Chinese dental laboratory with corresponding FPDs made in Swedish dental laboratories. Twenty-one patients were fitted with FPDs between March 2007 and December 2008. Single crowns and prostheses of up to seven units were made. All dentures, gold and CoCr alloys covered with ceramic, were produced in duplicate: one by a dental technician in China and the other by a dental technician in Sweden. The dentures were blind-tested with regard to marginal integrity, anatomic form and color, approximal and occlusal contacts, and time taken for adjustments. The composition of dentures was analyzed, and the material used, framework weight, compliance of the laboratories, and costs (material and labour) were recorded. There was no difference in the quality of marginal integrity, anatomic form, color, approximal and occlusal contacts, or in the time taken for adjustments. The bridge frameworks made in China were thinner and lighter (p<0.01) than those made in Sweden. Three FPDs from China showed elastic deformation when tested clinically and were considered too thin for clinical use. In 11 out of 14 orders from the Chinese laboratory, the gold alloy specified was not delivered and the cobalt-chromium alloy contained small amounts (0.19%) of nickel.The prostheses with gold-alloy frameworks from China cost 47% of those from Sweden (p<0.01) and those with cobalt/chromium frameworks 44% (p<0.01). In conclusion, the quality of the FPDs made in Sweden and China was comparable, with the exception of the dimension of the Chinese bridges, which in some cases was considered too weak. The gold alloy ordered from the Chinese laboratory was often not the alloy delivered and the CoCr alloy contained small amounts of nickel. FPDs from China cost less than half the price of those from Sweden.

Self-estimated oral and general health are related and associated with clinically investigated dental health
- 2011
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 35:4, s. 169-176
-
Tidskriftsartikel (refereegranskat)abstract
- The aim was to investigate whether the self-estimation of oral and general health is correlated and related to clinical parameters for dental health. Furthermore, to investigate the influence of socioeconomic factors on the self-assessment of oral and general health. During 2007 a dental health survey was performed in the Community of Gavle located in central Sweden.1,224 subjects randomized from the general population of Gavle (adult population 75, 000) were invited to participate. Seven hundred and forty-eight individuals answered a questionnaire regarding their health and 373 of these subjects participated in a dental examination. Self-estimated oral and general health was correlated (p<0.0001, r= 0.35) and individuals who perceived their oral health as bad had more decayed surfaces, surfaces with secondary caries,fewer teeth and more bleeding on probing than those with good estimated oral health (p<0.017 for all). In a logistic regression analysis with self-estimated oral health as the dependent variable was related to, the independent variables NT, DFT, self-estimated general health and age were related to self-estimated oral health, but not to income or educational level. However, subjects with low disposable income and low education level had significantly more clinical caries and fewer teeth than subjects with high income or a high educational level. Conclusions: In the present study, self-estimation of oral and general health was correlated and related to some clinical oral parameters. Subjects in the low socioeconomic group had worse dental health and a tendency to underestimate their need of dental care.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to measure patient-reported outcomes of caries prophylaxis and to compare them with previously documented efforts in dental offices. A questionnaire was mailed to 134 caries active (CA)and 40 caries inactive (CI) adult patients treated at a Swedish public dental service clinic. The overall response rate was 69%. The questionnaire included items regarding patient perceived caries prophylaxis in relation to:1) treatment and recommendations given by the dental personnel, 2) performed self-care and 3) perceived and expected effects. The responses were studied for their association to clinical data, extracted retrospectively from the patients' dental records. The mean follow up time was >16 years. Information about caries prophylaxis (p=0.01 and recommendations for self-care (p=0.04) were given more often to the CA group than to the CI group. Supplementary examinations and recommendations of self-care risk treatments were more frequent in the CA group (p<0.001). CA patients also made more frequent extra efforts at home to avoid caries by changing their eating habits (p<0.001), improving their oral hygiene (p=0.04) and using extra fluoride (p=0.00l). In the CA group, 60% did not consider that the extra prophylaxis efforts had made them caries inactive, and 40% were not satisfied with the outcome. Most patients (>90%) hoped that the outcome of caries prophylactics would be a reduced number of cavities. The patient-perceived experiences of caries prophylaxis-were in concordance with dental records. Both the dentists and the caries active middle-aged Swedish adults were aware of the need for extra prophylaxis. The caries active patients perceived having made extra home care efforts, but had not experienced that they had become free from caries.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- The aims of this study were to evaluate treatment outcome with activator-headgear combinations carried out by general dental practitioners, overall costs, long-term stability and patients' satisfaction with treatment outcome. Patients who were recommended to start treatment in 2006 were included in this study (n = 97). Inclusion criteria were: Class II Division 1 with at least half a cusp width distal molar relationship, overjet ≥ 6 mm and presence of dental records. Data were collected, pre-treatment, post-treatment and 3 years after treatment for those with favorable outcome. Patients at follow-up completed a questionnaire about satisfaction with treatment outcome, perceived pain and discomfort during treatment, and subjective need for additional treatment. Eighty-five patients were analyzed, 52 boys and 33 girls (mean age 11.2 years SD 1.39). Thirty-five patients had successful treatment outcome, 15 partially successful and 35 had an unsuccessful outcome. Total costs for all 85 patients amounted to SEK 1 405 000 including both direct and indirect costs. Thirty-eight patients participated in the 3-year follow-up. Treatment outcomes were then categorized as successful in 28 patients, partially successful in 9 patients and 1 patient was judged as unsuccessful. Median values on VAS (0-100) for overall satisfaction with treatment and treatment outcome were high, 78 and 84 respectively. Median value for perceived pain and discomfort during treatment was 42. Just over half of the patients had a favorable treatment outcome. Patients with favorable outcome were stable over time and satisfied with treatment.

Tobacco habits among teenagers in the city of Göteborg, Sweden, and possible association with dental caries.
- 1991
-
Ingår i: Swedish dental journal. - 0347-9994. ; 15:3, s. 117-23
-
Tidskriftsartikel (refereegranskat)abstract
- Frome nine dental clinics within the Public Dental Service in the City of Göteborg, 2145 patients aged 14 to 19 answered a questionnaire concerning their tobacco habits. Tobacco was used in some form by 27 per cent of the patients and use increased with age. Smoking was more common among girls than among boys: 24 and 12 per cent, respectively. The statistical analyses showed that smoking as a habit and an increased number of cigarettes smoked per day are positively correlated with increases in the number of decayed, missing and filled teeth and the number of initially decayed proximal surfaces. Further, all caries epidemiological data were significantly higher among patients with tobacco habits compared to non-users. It can be concluded that there is a correlation between the tobacco habit and increased caries prevalence. However, dietary and oral habits have to be further elucidated before any definite conclusions can be made regarding the effect of the tobacco habit per se on the development of caries.

Tidskriftsartikel (refereegranskat)abstract
- The responses of cell types in peri-implant tissues to cobalt-chrome and titanium were studied in vitro. Cylinders were made from both a cobalt-chrome alloy and commercially pure titanium (length 6 mm, diameter 7.9 mm). Plastic tubes were placed over the cylinders to create cell culture wells, in which human epithelial cells or mouse fibroblasts were cultivated. Cell viability was studied using the Alamar Blue method. The surface structure of two samples of each material was analyzed with optical interferometry. The morphology of cells grown on cylinders of each material was studied with scanning electronic microscopy. Epithelial cells and fibroblasts in the titanium group were more viable than those in the cobalt-chrome group (p = 0.001 and p = 0.000, respectively). The titanium surfaces had a greater height deviation (S(a), p = 0.027) but were less dense (S(ds), p = 0.044) than the cobalt-chrome group. The scanning electronic microscopy revealed no major deviations from normal cell morphology. Within the limitations of the present study, the findings indicate that epithelial cells as well as fibroblasts have a stronger negative response to cobalt-chrome alloy than to titanium. We suggest that these differences can be explained only bythe material per se and not by the minor differences in surface structure. Further and clinical studies are needed to confirm the significance of these findings.

Dentists and eating disorders - knowledge, attitudes, management and experience
- 2009
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 33:1, s. 1-9
-
Tidskriftsartikel (refereegranskat)abstract
- The aims of the present study were to explore the level of knowledge and attitudes among dentists in relation to patients with eating disorders (ED) and evaluate the extent to which patients with ED are identified and/or treated in the dental setting. A postal questionnaire was constructed and sent to all dentists (n=367) in two Swedish counties during November 200S. The questionnaire comprised 29 questions or statements in the following categories: demographics, general knowledge of ED and its oral consequences, experience of and attitudes towards patients with ED and interaction within the health care system,for example, referrals and treatment options regarding this patient group. The response rate was 70% (n=258). Perceived knowledge about ED was most commonly obtained from media sources, namely newspapers, television, etc. Few dentists knew that there existed specialized referral units for ED patients in their county. The majority of dentists stated that they had seen only a few such patients during their practice. Even though the perceived level of general knowledge about ED among female dentists appeared to be better than among male dentists,they also found it more difficult to inform the patient/relatives about their suspicion of the condition. Female dentists referred to specialists significantly more frequently than did males. Eighty-six percent of responders reported that they needed more training in dental management of patients with ED. Knowledge and clinical experience of dentists as regards patients with ED were found to be low. The level of education in this area needs to be improved, which would have the potential to encourage dentists to become more involved in secondary and tertiary prevention and management of ED.
