The Temporomandibular joint is the joint between the Temporal bone and the Mandible. It is a Ginglymodiarthroidal joint. It is related with some of the controversial and complex disorders. Under an identical situation, one person's TMJ may appear to worsen while another's doesn't. When the degenerative changes start in the TMJ, the pathology often leads to functional and morphological deformities. The usual pathology is non-inflammatory and characterized by abrasion of articular cartilage with thickening. This is followed by secondary inflammatory changes. The degenerative changes occur because of dysfunctional remodelling due to a decreased host adaptive capacity of the articulating surfaces or functional overloading of the joint. Thus, understanding the pathophysiology of the TMJ disorders is important for understanding the etiology, diagnosis, and treatment of TMJ. This paper reviews the factors associated with functional overloading of the joint and the clinical, radiographic and Biochemical findings important in the diagnosis of the Temporomandibular joint disorders.
