Normal masticatory function of girls and young women: mandibular masticatory movements

Mandibular masticatory movements were evaluated in a sample of young girls and women given gum to chew for 20 seconds. The study evaluated the timing and the excursions of the four phases of the masticatory cycle. The study was made to determine age-related differences during each phase of the cycle or in the mandibular excursions during the phases.
