The cause of TMD is very complex, as shown by the combination of psychosomatic, physiological, anatomical, postural and genetic factors, changing the balance between the basic entities of the stomatognathic system; which are occlusion, masticatory muscles and the joint.15 Pullinger and Seligman reported that low correlation exist between occlusion and TMDs.
The angles estimate the height of the coronoid and condylar processes respect to the dentary and therefore the orientation of the masticatory muscles (Emerson & Radinsky, 1980).
The results of this study showed that of all the masticatory muscles, the most severe pain at palpation was related to masseter, followed by the temporalis muscle.
