Prepubertal growth of mandibular prognathism.
This study deals with an analysis of the growth changes of the face associated with mandibular prognathism during a period before puberty. The investigation was based on two groups of Japanese girls--an experimental group of eighteen girls and a control group of twenty-two. Each set of serial lateral cephalometric roentgenograms consisted of a 4-year series from the ages of 7 to 10 years. Analysis was done on the annual size attainment of several facial components of the two groups. The results indicate that growth in cases of mandibular prognathism showed an incremental change similar to that of the normal group before the pubertal period.
