Comparative anatomic study of mandibular growth in rats after bilateral resections of superficial masseter, posterior temporal, and anterior digastric muscles
J. Lifshitz
Bilateral resections of the superficial masseter, posterior temporal, and
anterior digastric muscles of rats were done to determine their effects on
mandibular growth. The macroscopic findings support the functional matrix
theory of mandibular growth. The analysis of body weight and the
statistical two-way analysis of variance done suggest that malnutrition was
the main factor that caused the mandibles of rats in the experimental
groups of remain undersized.
