AB : The purpose of this study was to obtain the cephalometric maxillofacial soft tissue measurements and to define the differences that exist between male and female on the soft tissue profile who had normal occlusion in mixed dentitions. For the object of this study, cephalometric radiographs were obtained from the centric occlusion with the relaxed lip p osition.
Copper filter was designed to obtain both hard and soft tissue structure on the same film. The subjects consist of 100 male and 100 female from 8 to 12.4 years with the normal occlusion and acceptable profiles.
The author measured facial depth, vertical height from the cephalometric soft tissue profiles in the mixed dentitions. The significant test was performed to compare male with females.
The following results were obtained from the study
1. In facial convexity, much more larger female than that of male.
2. Inclination of the lip posture was more larger in maxilla (male) and in female more larger in the mandible.
3. The thickness of soft tissue was thicker in male, the height of nose was more prominent in female.
4. There were no significant differences in both sexes.
