ABSTRACT:
AIM: The aim of this survey was to evaluate the prevalence of TMDs. TMDs is a collective term that describes a sub-group of painful oro-facial disorders, involving complaints of pain on the Temperomandibular joint(TMJ) region and fatigue of the cranio-cervicofacial muscles, especially mastication muscles, limitation of mandibular movement and presence of articular clicking. Emotional stress, occlusal interferences, malpositioning or loss of teeth, postural changes, dysfunctions of the masticatory musculature and adjacent structures, extrinsic and intrinsic changes on TMJ structure and/or a combination of such factors are causes of TMDs. TMDs were assessed by three indicators like; clicking, tenderness and reduced jaw mobility (RJM). The tempromandibular joint is a hinge that connects your jaw to the temporal bones of the skull, which is in front of each ear. It lets to move the jaw up and down, side to side while talking, chewing and yawning.
