Degenerative temporomandibular joint diseases and their relation with sleep and emotional disturbance.

ABSTRACT

OBJECTIVE: The relation of degenerative temporomandibular joint (TMJ) diseases (DJDs) with sleep and emotional disturbance were investigated. METHODS: CBCT examination of patients (n = 358) with DC/TMD-defined intra-articular temporomandibular disorders was performed and stratified into NN no DJD and no arthralgia; NA no DJD with arthralgia; TO osteoarthrosis; and TR osteoarthritis. Sleep and emotional disturbance were assessed with the Pittsburgh Sleep Quality Index (PSQI) and Depression Anxiety Stress Scale-21 (DASS-21). Data were evaluated using non-parametric and multivariate logistic regression analyses (α = 0.05). RESULTS: Distributions of NN, NA, TO, and TR groups were 23.2%, 27.1%,19.0%, and 30.7%, respectively. No significant differences in total-PSQI/DASS scores were detected among the four groups. The presence of pain and stress predicted poor quality sleep with odds ratios of 10.75 and 1.07, accordingly. CONCLUSION: Sleep quality was affected more by arthralgia and stress than the presence of TMJ DJDs.
