Abstract

A roentgenocephalometric study was made from 365 subjects, that consist of 162 males, 203 females with normal occlusion, acceptable profile and no history of orthodontic and prosthodontic treatment. The results of this study were obtained as follows: 1. The tables of standards from the measurements by age, sex group were made. 2. All linear measurements of skeletal pattern in male were greater than in females. 3. The Bjork's sum was reduced gradually by aging in group I
