Background and Aims: Temporomandibular joint disorders (TMDs) are one of the most common causes of the patient's referral to dental clinics. Considering the role of related factors in its creation, the purpose of this study was to investigate the relative frequency of factors related to temporomandibular disorders in patients aged 20 to 50 years referred to dental clinics in Isfahan in 1397.
Materials and Methods: In this descriptive and analytical study, 324 patients referred to Isfahan dental clinics in 1397 were randomly included. Factors related to TMD and demographic factors of patients were recorded with clinical examination by a trained dentist and self-declaration of patients in the data collection form. The frequency and relevance were analysed by SPSS 22 software and chi-square, fisher and logistic regression statistic tests.
Results: At least one of the TMD related factors was present in 40.7% of the subjects, which the most common factors related to TMD was posterior edentulousness (49.7%). History of jaw dislocation was more common in men (P=0.014) and the frequency of posterior edentulousness was more common in in women (P=0.003). As the age increased, the frequency of posterior edentulousness (P=0.000) and earache (P=0.009) increased. The frequency of posterior edentulousness was higher in housekeepers (P=0.000), the frequency of earache was higher in employees (P=0.005) and the history of jaw dislocation was higher in self-employed persons (P=0.047).
Conclusion: The high prevalence of TMD and related factors, such as a history of jaw dislocation, posterior edentulousness, earache, and clenching, requires attention to be identified and treat these problems.
