Temporomandibular disorders (TMDs) are currently viewed as a family of related pain conditions in the craniofacial muscles, temporomandibular joint, and associated structures. The etiology and pathophysiology of pain is still far from being known, but several important neurobiological aspects have emerged in the last decade. This article reviews the present knowledge on three clinically relevant topics in TMD: referred pain mechanisms, somatosensory changes, and sensory-motor integration in the craniofacial region. It is proposed that the synthesis of this information from systematic studies in experimental animals and healthy human volunteers together with controlled clinical trials in well-defined patient populations is an essential prerequisite in order to advance the diagnostic procedure and management of TMD pain.
