- Overweight and obesity are increasing as health problems at global level. Dental caries and obesity are both multifactorial diseases and are associated with dietary habits. The aim of the present study was to investigate the relationship between body weight status and caries prevalence in an unselected population followed from pre-school years to young adulthood. The present investigation was designed as a longitudinal analysis of the association between overweight/obesity and dental caries in one population at 3, 6, 15 and 20 years of age. The result shows that adolescents (15 years) and young adults (20 years) who are overweight/obese had a statistically significantly higher caries prevalence than normal-weight young people. At 6 years of age, the odds (OR) of having caries among obese children are 2.5 times higher than the odds for caries among six-year-old children of normal weight (p = 0.04). At 3 years of age, no association between overweight/obesity and caries was found. To conclude, overweight and obese adolescents and young adults had more caries than normal-weight individuals. The present study emphasises the need for multidisciplinary approaches to change the lifestyle factors causing both overweight/obesity and dental caries.

- The study aimed to examine possible time trends in the prevalence of clinical signs indicative of temporomandibular disorder (TMD) in an adult population, to analyse possible associations between TMD signs and associated factors and to estimate the need for TMD treatment. Three independent, stratified and randomly selected samples of around 100 individuals in the age groups of 20, 30, 40, 50, 60 and 70 years participated in the Jönköping studies in 1983,1993 and 2003. The study material consisted of 1,693 subjects who, after answering a questionnaire and being interviewed about the presence of TMD symptoms, were clinically examined in terms of the presence of TMD signs according to the Clinical Dysfunction Index (Di) by Helkimo. Associations between clinical signs and the Di as dependent variables and each of the independent variables of age group, gender, reported bruxism, trauma, self-perceived healthiness and the year of investigation were analysed in binary logistic regression models. Estimates of the need for TMD treatment were based on the presence of a combination of severe symptoms and clinical signs. The prevalence of severely impaired jaw movement capacity, relating to horizontal movements, had increased in 2003. The prevalence of muscle pain and temporomandibular joint pain upon posterior palpation was found to vary statistically significantly between 1993 and 2003. Gender differences were noted in these changes overtime. Female gender, advancing age, awareness of bruxism, self-perceived health impairment and the wearing of complete dentures were associated with TMD signs and a higher degree of clinical dysfunction. The estimated need for TMD treatment increased from 5% in 1983 to 8% in 2003 and was higher in women than in men. In conclusion, the results indicate that the prevalence of some TMD signs and of estimated treatment need increased during the period 1983-2003.

- Use of moist snuff is widespread in Sweden. In 2004 approximately 8oo,ooo Swedes were daily users which corresponds to 22% of the male population and 3% of the female population. The aim of the present study was to evaluate the effect of Swedish moist snuff extract on PDLfibroblast growth and hard tissue production and compare with moist snuff extract from USA. Periodontal ligament cells (PDL-cells) were obtained from 3 healthy subjects (1 female 14 years, 2 males 14 and 17 years) from the root surface of premolars extracted for orthodontic reasons. The cells were isolated from explants and grown in Dulbecco's Modified Eagle's Medium (DMEM) supplemented with 10% fetal calf serum (FBS) and cultivated in 37 degrees C with 5% CO2 in air. Snuff extract in concentrations 0.3%, 1% and 3% (in DMEM with 1% FBS) was tested. Cells from each individual were tested three times, each time in triplicate. Photographs were taken at o and 24 hours with a digital camera and analysed in terms of growth and morphology. Then the cell suspension was frozen and later thawed for examination of the production of alkaline phosphatase after exposure to different snuff concentrations. This in vitro study has shown that PDL cells from 3 different subjects demonstrated a reduced number of cells at exposure to 3% of both Swedish and American snuff extract.The production of alkaline phosphatase after 2 hours was similarly reduced from cells exposed to 3% snuff extract. Further studies have to be made to understand the effect of smokeless tobacco on periodontal tissues. However, from this study can be concluded that smokeless tobacco has biological effects in terms of reduced PDL cell growth and production of alkaline phosphatase

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The use of Swedish oral moist snuff is a widespread habit in Sweden. In 1999, 25% of the adult male population and 3.1% of the female population were users of snuff. The aim of the present study was to evaluate how variations in pH and nicotine concentrations of snuff affect the oral mucosa, clinically and histologically, salivary pH and daily nicotine intake in 20 habitual users of loose snuff. The subjects were studied during use of their usual brand, after 12 weeks use of a snuff with lower pH and after another 12 weeks use of a snuff with both lower pH and lower nicotine concentration. Consumption data, oral soft tissue changes, salivary pH and nicotine intake were meas-ured. Further, biopsies were taken from the central part of the clinically observed lesions and histological changes were analysed. The subjects maintained their snuff consumption during the observation periods. The average salivary pH was higher during snuff use than in the morning. Further, it was higher shortly after the snuff was removed than during snuff use. After having switched to the snuff with both lower pH and lower nicotine concentrations, they showed a significant reduction in daily nicotine intake and developed significantly less pronounced clinical and histological changes. These results indicate that nicotine is one of the substances in snuff that has a biological effect on the oral mucosa. However, there also seems to be a synergistic effect between the pH and nicotine concentration in the snuff.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate whether the revenues cover the costs in a pilot capitation plan, a dental insurance scheme, and to compare this capitation plan (CP) with the original fee-for-service system (FFS), in terms of the amount and type of dental care provided. Data was collected longitudinally over a period of three years from 1,650 CP patients in five risk groups at a test clinic, and from 1,609 (from the test clinic) and 3,434 (from a matched control clinic) FFS patients, in Goteborg, Sweden. The care investigated was the number of total treatments provided and the number of examinations by dentists and dental hygienists, together with preventive, restorative and emergency treatments. The economic outcome was positive from the administrator's perspective, in all risk groups for the three-year period. The amount and type of care provided differed between the payment models, as CP patients received more preventive treatments, less restorative treatments, and more examinations by dental hygienists than the FFS patients. Emergency treatment was performed more often on CP patients, and the difference was due to a higher frequency of such treatments among women in the CP group. The difference between clinics concerning certain treatment measures was sometimes greater than the difference between payment models. The results from this study indicate a net positive economic outcome for the pilot CP system over three years. The payment model and the clinic affiliation had impact on what type and amount of dental care the patients received. This might suggest that the risk of skewed selection and its consequences as well as the influence of clinic-specific practice need further investigation, to ensure economic sustainability in a longer perspective.

- Objective. The aim of the study was to examine the fracture strength of fully anatomical monolithic high translucent Y-TZP, yttria-stabilized tetragonal zirconia polycrystal, crowns and to compare them with monolithic low translucent Y-TZP crowns in different thicknesses. Materials and methods. 80 standardized crowns were made out of a master model resembling a first mandibular molar made in composite material; 40 crowns made of Lava Zirconia by 3M ESPE, a monolithic low translucent Y-TZP material, and 40 crowns made of Lava Plus by 3M ESPE, a monolithic high translucent Y-TZP material. In each group ten crowns of the thicknesses 1.0 mm, 0.7 mm, 0.5 mm and 0.3 mm were made. All crowns underwent thermocycling and preload to simulate aging and normal wear. Finally the specimens were placed in a testing jig and underwent load to fracture. Results. No significant difference was found when comparing the two materials. When comparing the materials in each thickness a significant difference was found in the 0.5 mm group where the high translucent YTZ-P had a higher mean fracture strength value. A significant difference was seen between the different thicknesses within both groups. The strength increased with added thicknesses. Conclusions. The low translucent and high translucent monolithic YTZ-P perform equally well. The use of high translucent monolithic Y-TZP could result in more aesthetic results and the minimal invasive preparation could lead to a reduction in biological complications. This could be beneficial for the patient since the results suggest that even a thin restoration sustains reasonable load in an in vitro environment. Clinical studies are needed to confirm this suggestion.

Use of implant-supported prostheses in edentulous mandibles among prosthodontists in Sweden.
- 2014

Ingår i: Swedish Dental Journal. - 0347-9994. ; 38:4
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to investigate the production of mandibular implant-supported fixed and removable prostheses among prosthodontic specialists in Sweden and to compare the results with findings in a similar study made in 2001 (16). Questionnaires regarding treatment with mandibular implant prostheses during 2011 were sent to all specialists in prosthodontics in Sweden (n = 156, according to available data). A total of 129 questionnaires were received from 129 (83 %) prosthodontists of which 114 were completed. The reported number of treatments with mandibular implant-supported prostheses varied much among the specialists. Fixed implant prostheses were more common than overdentures, but the range was large. Tio (9 %) of the specialists reported no treatment with fixed implant prostheses while 29 (25 %) had not made any implant overdentures during 2011. The most common anchorage system for overdentures in 2011 and in 2001 respectively, was two un-splinted implants with ball attachments or locators The most common reasons for the choice of overdenture treatment in 2011, as well as in 2001, were the reduced cost and the patient’s main wish to improve denture retention. In 2011, 58% of the prosthodontists responded that patients with implant overdentures were as satisfied as those with fixed implant-supported prostheses, whereas 40 % claimed they were less satisfied. Two respondents (2 %) considered that overdenture patients were more satisfied than those with a fixed prosthesis. It can be concluded that the general attitude among Swedish prosthodontists towards implant overdentures has not changed much during the 10-year period between the present and the previous investigation. An overdenture is still a seldom-used option in implant treatment of patients with edentulous mandibles. A fixed implant-supported prosthesis continues to be the preferred option.
