Study on the craniofacial growth for Japanese school children

Abstract

We investigated the craniofacial growth and development of 120 Japanese elementary school children (60 males and 60 females). The subjects were divided into six groups based on their skeletal facial patterns (Class I, Class II or Class III) and gender. We did statistical calculations on the angular and linear measurements using tracings of head radiographs.
We found that growth at the anterior cranial base was lowest in the Class III 4th graders. However the amount of the anterior growth at the maxillofacial complex in the Class II group was less than in the other groups. The Class Ⅲ group showed more clockwise rotation than the other groups. Increases in the inclination of the upper and lower incisors were seen in all groups. Boys showed more growth change in the craniofacial complex than did the girls.Shika Igaku(J Osaka Odontol Soc) 2003 Jun; 66(2): 183-197.
