A mouth opening index for patients with temporomandibular disorders.
Limitation of mouth opening is an important sign of temporomandibular disorders. It is usually measured linearly from the incisal edge of the maxillary incisors to the incisal edge of the mandibular incisors. This measurement has been queried. A new measure of mouth opening, the opening index is suggested. It was shown that the mean opening index differs for groups of patients with a myogenous or arthrogenous temporomandibular joint problem.
