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

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 (alpha = 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.

Automated summary

The study indicates a relationship between degenerative temporomandibular joint diseases (DJDs) and sleep and emotional disturbance. The presence of pain and stress significantly predicted poor sleep quality.
