Temporomandibular joint disorders (TMDs) are familiar yet difficult to diagnose in routine practice due to the complexity of the joint and its surrounding structures. The symptoms usually associated with TMDs present with pain, joint sounds such as click or crepitus, difficulty during mastication, reduced mouth opening are some of the many presentations. Definite diagnosis of the TMDs can be challenging as the patients present with varying symptoms. These disorders of the joint can vary from a simple disc displacement to complex pathologies.
