A LONGITUDINAL STUDY OF KOREAN CHILDREN'S PROFILE CHANCE IN RELATION WITH
MANDIBULAR GROWTH PATTERN

(Directed by prof. Young Kyu Ryu,D.D.5.,Ph.D.)
Vertical and horizontal growth occur in the craniofacial complex which ensues
continuous changes in facial morphology, until the end of active growth period.
Longitudinal study for individual is essential, in the research on growth and
development, however, the difficulties in obtaining long term subjects in Korea,
the research has been limited.
The author analyzed the cephalometric roentgenogrems of 43 boys and 47 girls
taken from the ages 6 to 10.
The subjects were divided into 3 groups according to SN-MP angle and 2 groups
according to genial angle.
In this longitudinal study,21 variables were measured.
The obtained results were as follows:
1. SN-MP angle and gonial angle had no significant changes in each group with
age.
2. With age, facial convexity of hard tissue decreased in all groups, facial
angle of hard tissue increased in low SN-MP angle group, but facial convexity of
soft tissue had no significant changes in all groups with age.
3. In comparison of high SN-MP angle group and low SN-MP angle group, the former
had greater facial convexity and smaller facial angle than the latter.
4. SN-MP angle and the ratio of posterior dental height to anterior dental height
had reverse correlation in all groups.
5. High gonial angle group revealed larger SN-MP angle, anterior dental heights
facial convexity, but smaller mandibular length, and the ratio of posterior dental
height to anterior dental height compared with low gonial angle group.restrictio
