Abstract
In order to investigate the possibility of using a cervical vertebral maturation indicator as a mandibular growth indicator, the relationship of cervical vertebral maturation and mandibular & body height growth changes was assessed in biennial serial lateral cephalometric raadiographs of eighteen korean male and fourteen korean female while they were 8.5 to 185 years old.
The following results were obtained.
1. It was a reliable method to evaluate skeletal maturation by using cervical vertebrae.
2. In general, cervical vertebral maturation stages of females were higher than those of males at the same age and there were significant differences in statistics at the age of 105, 14.5.
3. The age of a female at the same cervical vertebral maturation stage were earlier than that of a male.
4 In the case of males, significant Ar-Gn increases were found between stage 3 and 4,5 Ar-Go increases between stage 4 and 5.
5. In the case of females, significant S-Gn and Ar-Gn increases´, were found between stage 3 and 4.
6. Significant body height increases were found between stage 3 and 4 in both sexes.
7. The peak velocity of body height and mandibular length was observed between cervical vertebral maturation stage 3 and
4 in botli series. .
8. The relationship between- inandibular & body height changes and specific maturation stage of cervical vertebra was found, therfore using a cervical vertebral maturation indicator as mandibular growth indicator is quite within realms of possibility.
