Temporomandibular disorders are musculoskeletal conditions characterized by facial pain and impaired temporomandibular joint function, limited mouth opening, joint and muscular pain, and noises during mandibular movements are some of the most common symptoms. The most frequent cause of temporomandibular joint dysfunction is internal derangement (ID), which refers to an alteration in the normal pathways of motion of the joint that largely involves the function of the articular disc, therefore, these alterations have been also referred to as disc derangement. Arthrocentesis is a minimally invasive technique, less expensive than surgical treatment. Adhesions are released after arthrocentesis of the upper joint space under sufficient hydraulic pressure. Intra-articular ozone gas injection is used as conservative treatment modalities for ID of the temporomandibular as it possesses anti-inflammatory, analgesic effects, enhancement the host defense mechanism and accelerates the healing process of the damaged cells.
