- Biofilms are formed in the dental unit waterlines, which leads to unacceptable high levels of bacteria in the water used for dental treatment. Public Dental Health in Vastra Gotaland, Sweden, decided in 2010 to install water cleaning systems in all dental units. This report shows the effect of this water-cleaning program comprising 841 dental units. The 841 dental units in 111 clinics in the Public Dental Health Service of Vastra Gotaland region participated in the study. 50 ml water was sampled from the air-water syringe after 2-3 hrs of use and were analyzed for the number of fast-growing,(2 days incubation) and slow-growing (7 days incubation) bacteria calculated as colony forming units (CFU) per ml. Approved water quality was set to <100 CFU/ml according to the recommendations from the Board of Health and Wellfare (Socialstyrelsen). Altogether 77.3% of the dental units reached approved levels, which was considerable higher than the 25.2% that were approved in a similar study at FTV in the city of Goteborg 4 years earlier when no water cleaning systems Were installed. Further, 474 dental units using the Alpron/Bilpron weekend system 83.4% were approved, 136 units using Unit Clean system 87.5% were approved and 15 using the Sterilox system all reached below loo CFU/ml. The 199 dental units with inbuilt cleanings systems by the manufacturers based on hydrogen peroxide only 56.3% were approved. A number of 45 (22.6%) showed very high levels (>10 000 CFU/ml) indicating serious problems with the practical procedures or installation of the systems that needs further attention. The study showed generally improved conditions of the water in the dental units after the introduction of water cleaning systems in the clinics of Public Dental Health Service of Vastra Gotaland Region, Sweden although the problem still remains in many units.

Tidskriftsartikel (refereegranskat)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.

Micro-topography of dental enamel and root cementum.
- 2009
-
Ingår i: Swedish dental journal. - 0347-9994. ; 33:1, s. 41-8
-
Tidskriftsartikel (refereegranskat)abstract
- The focus for the present study was to characterise dental enamel and cementum at the cervical region of healthy teeth by use of interferometry. The effect of a protein-dissolving enzyme, used for cleaning (Neutrase) on the surface topography, was also evaluated. Knowledge about the normal variation of surface topography of natural teeth is limited. In the design of artificial surfaces, intended to replace the function of lost biological surfaces, detailed knowledge of the latter is therefore of great importance. Nine health caries free premolars were used. The root cementum of three teeth was used for evaluation of Neutrase on the surface. On the six remaining teeth, the differences between the surface textures of enamel and root cementum were evaluated using 3D Interferometry. No statistical significant effect of Neutrase was identified. A significant difference between enamel and root cementum concerning surface topography using the different 3D parameters was recorded. When comparing values from the literature, the topography of artificial materials used in dentistry show similarities with the topography of the enamel and root cementum surfaces evaluated.

- 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 impact of oral health on quality of life is one aspect when it comes to understanding the significance of oral health. The aim of this sudy was to analyse the self-reported oral discomfort and clincial status of individuals reporting oral problems never/very seldom affexting quality of life during the last year and compar ehem with individuals who reported oral problems hardly ever/occasiaonally or often/very often during the same period. The study comprised a stratified random sample of 515 individuals who lived in four parishes in the City of Jönköping, Sweden, and tyrned 20, 30, 40, 50, 60, 70 and 80 years of age in 2003. The impact of oral health on quality of life was examined using the OHIP-14 questionnaire. The individuals were also examined clinically and radiographically. Of the participants, 21 % reorted no experience of impaired quality of life and 20 % of the indivudals reported that they had expperienced impaires quality of life often or very often during the last year. The highest frequency of oral problems was found among individuals aged 20 and 80 years. Subjective symptoms, such as grinding/clenching and headache, were found among 20- and 30-year-olds. Edentulous individuals with many missing teeth, individuals with severe periodontal disease or subjective dry mouth answered that they experienced problems accordning to the OHIP-14 often or very often. A number of individuals, young and old, had thus experienced subjective or clinically verified oral conditions associated with a negative experience of quality of life. This complementary information will provide a deeper understanding of the importance of oral health in the population.

Tidskriftsartikel (refereegranskat)abstract
- Sjukdomar och medicinska tillstånd definieras vanligen genom att ett antal kriterier uppfylls och en individ bedöms som frisk från sjukdom när dessa kriterier inte längre föreligger, ofta efter en definierad tidsperiod. Incidens och prevalens mellan olika sjukdomar kan därför ofta jämföras. I longitudinella studier definieras dental karies ofta som förändringar i medeltal av ett index, vanligen DMFT/S. Karies är en livsstilssjukdom som går att bota, men symtomen på kariessjukdom är oftast persisterande vilket innebär att ett sådant index inte redovisar hur många individer som är sjuka under en viss period eller hur många som är botade från själva kariessjukdomen under samma tid utan istället redovisar en livstidsprevalens. Syftet med denna studie var att beräkna karies incidens och karies prevalens utgående från begreppen årsprevalens, kumulativ incidens och incidenstalet (incidensraten). Definition på karies hämtades från ICD-10 (KO2.1) som beskriver diagnosen för karies in i dentin. Som definition på att vara frisk (botad) från kariessjukdom användes en definierad tidsperiod på tre år utan att ny dentinkaries registrerats. Studiepopulationen var 423 individer och bestod av alla 12-åringar i Örebro län, år 1990, och som under sex år deltog i samtliga årliga recall-undersökningar (1990–1995). Av dessa hade 210 dentinkaries (definierat som ICD K02.1) någon gång under de tre åren 1990–1992 medan 213 inte uppvisade dentinkaries någon gång under samma tidsperiod. Under den efterföljande perioden 1993–1995 blev 17 % av de sjuka barnen friska från karies. Av de friska barnen insjuknade 38 individer vilket ger en årlig prevalens av 12 %. Karies hade en incidens rate av 134 fall per 1000 manår (13 %) och en kumulativ incidens på 15 % för ett år, 17 % för två år och slutligen 18% för tre år. Vår definition av den tid som krävs (3 år) för att kunna avgöra om en tidigare sjuk individ kan bedömas som frisk från karies kan i framtiden behöva justeras och fler studier i olika åldrar och populationer behövs för att ytterligare belysa problemställningen. Studien visar på relativt dåligt resultat när det gäller att bota kariessjukdom då endast 17 % av de sjuka blev friskförklarade under en period på tre år. Likaledes är resultaten av preventionen nedslående då hela 12 % av individerna i den friska gruppen blev sjuka. Resultatet bör dock tolkas med försiktighet med tanke på det begränsade antal barn som ingick i studien och risker för selektionsbias mellan grupperna. Under dessa år hade dock individuella kallelseintervall utifrån ett riskperspektiv inte införts hos Folktandvården Örebro utan orsaken till att barn inte kallades årligen berodde vanligtvis på resursbrist hos vårdgivaren. Denna metod att rapportera karies i longitudinella material och därmed definiera karies på individnivå ersätter inte traditionella metoder för att mäta kariesincidens och kariesprevalens. Metoden ger dock en ökad information avseende det antal individer som faktiskt är sjuka i karies. Ett sådant förfaringssätt medför stora fördelar ur planeringssynpunkt för tandvården då fokus blir individer och inte medeltal av ytor eller tänder, och möjliggör dessutom jämförelser mellan dem som faktiskt är sjuka i karies med dem som diagnostiserats med andra sjukdomar.

Treatment Outcome of Headache After Occlusal Appliance Therapy in a Randomised Controlled Trial Among Patients with Temporomandibular Disorders of Mainly Arthrogenous Origin
- 2002
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 26:3, s. 115-124

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate headaches before and after treatment with a stabilisation appliance and a control appliance in a randomised controlled trial in patients having temporomandibular disorders (TMD) of mainly arthrogenous origin. The effect of treatment was evaluated both in a short and in long-term perspective. 60 patients (mean age 30 years) with TMD of mainly arthrogenous origin were studied. The patients were selected from patients referred for treatment of TMD during a 3-year period to the Department of Stomathognathic Physiology, Faculty of Odontology, Malmo University. The 60 patients included in the study were randomly assigned to a treatment (T) or a control (C) group. The study was performed as a randomised controlled trial including evaluation of treatment effect on tension-type headache after 10 weeks, 6 and 12 months. At the 10 weeks follow-up, the patients who reported a negative treatment outcome and/or discomfort associated with the use of the appliances had their appliances readjusted. Patients who demanded further treatment received a stabilisation appliance (21 patients from the C-group), creating a new mixed (M) group. All the 60 patients reported frequency of headache from rarely up to daily at the start of the study. In the T-group 76% and in the C-group 83% of the patients reported headache at least once a week or more before treatment. At the 10 weeks follow-up, a statistically significant difference was found regarding headache several times a week or more between the T- and C-groups and within the T-group. At the 6 months follow-up, a statistically significant reduction was found in headache several times a week or more in the T- and M-groups. The number of patients with headache once a week or more decreased significantly in the T- and M-groups at the 12 months follow-up. We conclude that the stabilisation appliance seems to have an effect on the frequency of tension-type headache both in a short and in a long-term perspective in patients with TMD of mainly arthrogenous origin.

Ingår i: Swedish Dental Journal. - 0347-9994. ; 35:3, s. 111-121
-
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.
