AGE CHANGES OF THE MANDIBULAR ANGLE IN CHINESE / 解剖学报

ABSTRACT

Age changes of the mandibular angle of 406 Chinese specimens were studied. It is concluded that the mandibular angle decreases from the childhood to the adult, but there is no remarkable change at old age. The mean angle of the female is 2.9?to 5.3?larger than in the male. The angle on both sides is not equal in 90% of cases, and the difference reaches 3～10?in roughly 40% of cases. The changes of the angle are related to the function of the mastication and the growth of the mandible.
