In order to define a current set of Korean children norm with mixed dentition, following study was done.
The subjects were 102 healthy dentition contestants(48boys, 54girls) Standardized lateral head roentgenograms were taken, and Ricketts analysis was done. Results were as follows
1. Length of anterior cranial base, posterior facial height, corpus length were longer in male than in female(p(0.05), and Porion was located posteriorly in male than in female(p(0.01).
2. Through facial depth, Pogonion of male was more forwardly positioned (p(0.05), mandible was significantly steeper in female, and maxillary anterior teeth were significantly tipped forward in male(p(0.05).
3. Variables such as length of anterior cranial base, upper molar position (p(0.01) and corpus length(p(0.05) were significantly changed by age.
4. Maxillary height, facial depth, mandibular plane angle, convexity were changed by age, but not significantly(p)0.05).
