Background and Aims: Sleep quality may be a predictive factor for temporomandibular disorders (TMD) compared to other risk factors. Patients with TMD may experience quality-of-life problems such as sleep disorders and orofacial pain. Timely diagnosis of TMD can halt its progression in the initial stages and reduce its severity. This study aimed to investigate the frequency and severity of temporomandibular joint disorders and their co-occurrence with sleep quality among dental students in Yazd in 2023.
Materials and Methods: This descriptive study was conducted among 211 students at the Yazd Dental School. The Fonseca and PSQI questionnaires were used to determine the severity of TMD and sleep quality, respectively. Clinical examination was conducted to assess the symptoms of TMD. Additionally, demographic information such as gender, marital status, and place of residence was recorded. The data were analyzed using chi-square and t-tests.
Results: The final analysis was performed on 211 individuals, comprising 118 males (56%) and 93 females (44%). Among all the participants, 204 individuals (83.88%) had at least one symptom of TMD. The participants' most prevalent symptoms were jaw sounds, midline deviation, pain, and mouth opening limitation. There was no significant difference in the frequency of TMD symptoms, jaw sounds, jaw deviation, and limitation in opening, based on gender. Similarly, the prevalence and severity of TMD and their symptoms showed no significant association with residence or marital status (P>0.05). Although, a correlation was observed between the poor sleep quality and the severity of TMD, no association was found between the presence of TMD symptoms and poor sleep quality (P>0.05).
Conclusion: While, the frequency of TMD symptoms did not differ significantly between genders, the severity of TMD and jaw pain was significantly higher among female students. Individuals with poor sleep quality exhibited significantly higher severe degree of TMD.
