Comparative Evaluation and Correlation of Pain Pattern in Neck Musculature Observed in Mild, Moderate, and Severe Temporomandibular Joint Disorder Cases as Compared to Non-temporomandibular Joint Disorder Cases.

Introduction Temporomandibular disorder (TMD) is a broad term used to describe several interlinked disorders affecting the temporomandibular joint (TMJ), muscles of the craniofacial region, and associated structures, all of which have common symptoms such as pain and reduced jaw opening. Along with these, extra-craniofacial symptoms may also be present, which need to be assessed for early diagnosis of TMD. Considering the extra-craniofacial symptoms of TMD, this observational study aimed to evaluate the severity of pain in the neck musculature of patients with TMD and correlate it with the severity of the disorder.
