title: Evaluation of masticatory function before and after treatment in patients with craniomandibular disorders.
abstract: The masticatory function was evaluated in 12 patients with signs and symptoms of craniomandibular disorders of mainly muscular origin. Palpation of the masticatory muscles and measurements of occlusal force endurance, on a submaximal level with visual feedback, and of masticatory efficiency were performed before and after treatment. Significant changes occurred between the two measurements. Of a total of 10 masticatory muscles, 8 were sensitive to palpation before treatment and 2 after treatment. Occlusal force endurance increased from 92.5 seconds before treatment to 132 seconds after treatment, and masticatory efficiency increased from 54% to 65%, respectively. It is concluded that the masticatory muscle function of these patients is compromised and that treatment had a positive effect on the masticatory function.
