Association between temporomandibular disorders with clinical and sociodemographic features: An observational study.

Background: Temporomandibular disorders (TMD) are the most common orofacial impairment, but the relevance of certain clinical features in TMD is not clear.

Objective: The main objective of this study was to analyse if temporomandibular disorders (TMD) are associated with sociodemographic (eg age, height, weight, body mass index and gender), psychological (eg anxiety and depression) and clinical features (eg use of dental splints, orthodontics, retainers, bruxism, sleep disturbance, familiar prior history of TMD and dental occlusion).

Methods: An observational study was conducted to calculate the correlation of TMD, as assessed with DC/TMD criteria, with sociodemographic, psychological and clinical features on 59 voluntary subjects with TMD (n = 45) and without TMD (n = 14).
