Description
Summary:	Background and purpose: The present study assessed the incidence of Temporomandibular Disorders (TMD) and its relationship with demographic variables, previous orthodontic treatment, and mandibular mobility in patients attending Sari Dental School. Materials and methods: In this cross-sectional study, 68 individuals were randomly selected. Data were obtained by interviewing the patients and clinical examinations. The relation between TMD and other variables was then analyzed applying Chi-square test and exact fisher test in SPSS V22. Results: TMD was found in 75% (n=51), including 35.3% of men and 64.7% of women. Among these, 14 had previously received orthodontic treatment, 34 had a monthly salary of less than one million tomans ($30), and 49 were city dwellers. Maximum mouth opening was 44.52±7 mm in patients without TMD (P= 0.84). People without TMD had greater maximal lateral mandibular movement to the right (P= 0.2) and left (P= 0.84), but this was not statistically significant. Conclusion: A history of orthodontic treatment can contribute to the development of TMD. Nevertheless, good financial status helps in benefiting from more follow-up treatments and decreases the incidence and progression of TMD, although this was not significantly correlated with other variables.
