The purpose of this study was to obtain roentgenocephalmetric norms of the Korean
mixed dentition children which are used in the occlusal guidance treatment.
The 121 subjects(57 males and 64 females) were consisted of mixed dentition children
who showed up in Department of Pediatric Dentistry Seoul National University Hospital
from June 1990 till February 1993 3nd contestants of the Heathy Dentition Contest in
1992 and 1993.
The subjects had normal profiles and occlusions without severe carious lesions or
missing teeth.
Following results were obtained from Sassouni, Ricketts and McNamara analysis ;
1. Norms and standard deviations of the children were obtained.
2. ANS, upper incisor, pogonion, upper 1st molar and gonion were located posterior to
their reference arcs and point B was located anterior to its reference arc.
3. Lower anterior facial height was longer than upper anterior facial height and upper
posterior facial height was longer than lower posterior facial height.
Mandibular corpus length was longer than anterior cranial base length.
4. Anterior cranial length was longer in male(p<0.05) and mandibular corpus length
was longer in male than in those of female(p<0.01).
Portion was located more posterior in male than in those of female(p<0.05)
5. Effective mandibular length and lower anterior facial height were longer in male
than in those of female(p<0.005).
Effective midfacial length was longer in male than in those of female(p<0.05).
