두개안 골격형태에 관한 두부방사선학 연구

Lateral cephalometric head film measurements on forty schoolboys and forth-nine schoolgirls with excellent occlusions in Korean were compared with similar measurements on Caucasoids. The following conclusions were obtained. 1. The cranio-facial skeletal pattern of Korean students was measured and compared with Caucasoids. 2. In cranio-facial observation, ANB and SN-Palatal plane was not significant in girls only, Gonial angle and 1 to NA were not significant in girls and boys, compared with Caucasoids. 3. In dentition area observation, the mean posterior dental height (A＋B) and occlusal plane length was not significant in girls only, the mean anterior vertical dimension and P angle was not significant in boys, Q angle was not significant in boys in boys and girls, compared with Caucasoids.
