The purpose of this study was to investigate the relationship of the development of
teeth and the bone maturity of hand-wrist during pubertal growth period in Korean.
The subjects used in this study were 295 children(male 147, female 148), ranging from 8
to 16 years of age, with good general health, none of whom had received orthodontic
therapy. Panoramic radiographs and hand-wrist radiographs were used to evaluate to
stage of teeth development and the bone maturity of hand-wrist and their relationship.
The results were as follows ;
1. In bone maturity of hand-wrist, a definite trend toward acceleration among females
was evident, and in tooth maturation, a definite trend toward acceleration among females
was evident in upper and lower canines.
2. In stage 3 of bone maturity of hand-wrist(onset of pubertal growth), the percentage
distribution of developmental stage G in lower canine was the most high(77%). The two
os of the above were highly coincided with each other.
3. In spite of variety in correlation between teeth development and bone maturity of
hand-wrist, there was the relatively close correlation in the lower first premolar in
male(R=0.57) and the lower second premolar in female(R-0.73).
4. There was the highly close relationship between chronologic age and bone maturity
of hand-wrist(R=0.82 in male, R=0.84 in female). However the correlation between
chronologic age and teeth maturation was low, and different among various
teeth(R=0.11-0.52).
