Orofacial pain and tooth wear in swedish adults : cross-sectional studies in southern Sweden

Aim. The present licentiate thesis investigated the prevalence of TMDpainand related factors, the prevalence and severity of tooth wear, andthe etiology and factors related to tooth wear in adults in southern Sweden.Methods. The methods used included a questionnaire, history, clinical examination,intraoral photographs, and saliva sample. In Paper I, twoscreening questions for TMD pain were used to query a study samplecomprising 6123 questionnaire participants about their pain experience.In Paper II, a clinical examination and intraoral photographs helped determinethe presence and severity of tooth wear. Information from a questionnaire,patient histories, and participant saliva samples were analyzedregarding tooth wear-related factors. The study sample comprised 831 individuals.Results. Paper I found a prevalence of TMD pain once a week or moreoften in 11% of the study sample. Related factors were female gender,subjects under 50 years of age, weekly headache, self-reports of poor generalhealth, impaired oral health-related quality of life, and tooth wear.Paper II showed tooth wear in all individuals. Attrition, the most commontooth wear, was found in over 90% of the study sample. Signs of erosionwere found in almost 80% of the individuals. Men had more tooth wearthan women, but none of the factors that were investigated as related factorsdiffered between the genders. Only some of the individuals, includingthe group with severe tooth wear reported having received information about tooth wear from their clinician. Participants reported receiving informationabout tooth wear due to extensive tooth brushing more thanabout erosion.Conclusions. Paper I found a prevalence of TMD pain in 11% of the studysample. In Paper II, attrition was found in over 90% of the study sample.Almost 80% of the individuals exhibited signs of erosion. Only a few reportedhaving received information about tooth wear due to erosion fromtheir clinician

TMD-pain among adults in the county of Scania, Sweden

Objectives: This study evaluates the prevalence of TMD-pain in adults in the county of Scania, in the south of Sweden. Methods: A questionnaire was in 2006 mailed to a randomized selected sample of 10 000 individuals in the county of Scania. If the individuals answered yes to one or both of following questions, the subject was classified as having TMD-pain (1) “ Do you have pain in your temples, face, jaw joint or jaws once a week or more?” and (2) “Do you have pain when you open your mouth wide or chew once a week or more?”. The questions have previously shown high validity and reliability for TMD-pain among adolescents. Results: 6123 individuals answered the questionnaire. 1210 individuals (20.4 %) reported TMD-pain. Mean age was 47 years, with a female-male ratio of 7:5. A higher prevalence of TMD-pain was found for the ages 20-59 with the highest figure for the ages between 20 and 29 years. TMD-pain was reported by 19–21 % of individuals born in Sweden or another Nordic country compared to 32 % of the individuals not born in the Nordic countries. Length of education was not related to TMD-pain. A higher prevalence of reported TMD-pain was found for individuals being unemployed, retired or were on sick leave compared to other occupations. Among individuals living with a partner, 19% reported TMD-pain compared to 23% among those living alone and 27% with another family situation. Conclusion: The study found a high prevalence (20.4 %) of TMD-pain among adults in the county of Scania. Highest prevalence (32%) was found among adults not born in a Nordic country

TMD-pain among adults in the county of Scania

Introduction: The prevalence of TMD has been shown in epidemiological studies to be 10-15 % and it is most often women in their 20-40´s, but also men, children and elderly have TMD. The most common reason for seeking care for TMD seems to be pain. In a recently published meta-analysis of the epidemiological literature the need for TMD treatment was estimated to be about 15 % among adults. Objectives: This study evaluates the prevalence of TMD-pain in adults in the county of Scania. Methods: A questionnaire was 2006 mailed to a randomized selected sample of 10000 individuals in the county of Scania. If the subjects answered yes to one or both of following questions, the subject was classified as having TMD-pain (1) “ Do you have pain in your temples, face, jaw joint or jaws once a week or more?” and (2) “Do you have pain when you open your mouth wide or chew once a week or more?”. Results: 6123 subjects (64%) answered the questionnaire. 1210 subjects (20,4 %) reported TMD-pain. Mean age was 47 years, with a female-male ratio of 7:5. A higher prevalence of TMD-pain was found for the ages 20-59 with the highest figure for the ages between 20 and 29 years. TMD-pain was reported by 19–21 % of subjects born in Sweden or another Nordic country compared to 32 % of the subjects born in another country. Length of education was not related TMD-pain.
