| Research Abstract |
This study examined the preferred chewing side with comparison to the anterior disc displacement(ADD) of temporomandibular joint(TMJ) and the movement of mandibular incisal point(MMIP) in chewing soft and hard foods. In subjects without ADD of TMJ, a laterality of MMIP was not observed in chewing soft and hard foods. In subjects with unilateral ADD of TMJ, unbalanced MMIP was observed in chewing hard food. Moreover a laterality of MMIP could be assumed to be with correspondence to a side of ADD.
