Comparison of moist and dry heat penetration through orofacial tissues.

Application of superficial moist heat has been shown to have a beneficial effect on Temporomandibular Disorder (TMD) symptoms and is often recommended for patients with this disorder. A review of the literature shows that few studies have compared the effects of moist to dry heat. Throughout this study, moist and dry heat were applied through a commercial heating pad alternately for 20 minute intervals.
