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. |
