Abstract

Abstract: PURPOSE: To investigate the prevalence of temporomandibular disorders (TMD) in undergraduates of Xinjiang Medical University and analyse its possible risk factors. METHODS: A sample of 700 medical students included 244 males and 456 females was selected from Xinjiang Medical University and underwent examination of temporomandibular joint, questionnaire survey. Their average age was 20.08±1.457 years. Prevalence of TMD was analyzed, and the possible risk factors associated with the disease were identified by logistic regression analysis with SPSS17.0 software package. RESULTS: The prevalence of TMD was 42.40% in this population. There was no difference between different ethnics. Chewing-side preference, bruxism,orthodontic treatment,tooth extraction,psychological factors,anterior overjet, posterior scissors-bite were the main risk factors which increased the occurrence of TMD. CONCLUSIONS: Poor oral habits, psychological factors and malocclusion were related to the development of TMD.

Key words: Temporomandibular disorders, Occlusal factors, Scissors-bite, Psychological factors, Bruxism
