Objective: To investigate the prevalence of temporomandibular disorders in Urumqi undergraduates. Methods: A total of 1 223 university students of all ethnic groups from the freshmen to the third grade of five universities in Urumqi were randomly selected for epidemiological investigation of temporomandibular joint disorder. Survey includes general items, review of history, oral health behavior, clinical examination and other four aspects. Statistical analysis SPSS18.0 statistical software, line chi-square test, test level is defined as: If P> 0.05, the difference was not statistically significant; if P <0.05, the difference was statistically significant. Results: The prevalence of temporomandibular disorder was 51.1%, the prevalence rate was 48.91% in males and 53.93% in females, and the prevalence of females was higher than that of males (P <0.05). There was no significant difference between males and females (P = 0.081). The incidence of abnormal jaw group was significantly higher than that of normal jaw group, and the occlusal relationship was not statistically different between TMD group and non-TMD group (P = 0.184). Conclusion: There is a significant difference between TMD group and non-TMD group in caries status, bad habits and mental factors of the first molar.
