Abstract

This study aimed to investigate the correlation between maxillary canine's dental maturity and skeletal maturity of growing children. Cephalometric radiographs, hand-wrist radiographs and panoramic radiographs of 299 children aged 6 - 17 years were analyzed to measure the cervical vertebral maturation stages (CVMS), skeletal maturity indicators (SMI) and Demirjian index (DI). Spearman correlation test was used to analyze the correlation between dental maturity and skeletal maturity. There was significant positive correlation between the DI and CVMS in both boys and girls (p = 0.000). Similarly positive correlation was found between the DI and SMI (p = 0.000). The results of this study suggest that the dental maturity of maxillary canine can be used as auxiliary maturity indicator in growing children.

이 연구는 성장기 아동의 방사선 사진을 이용하여 상악 견치의 치아 성숙도와 골격적 성숙도를 평가하고, 상악 견치의 치아 성숙도와 골격적 성숙도 사이의 연관성을 알아보고자 하였다. 치아 성숙도는 Demirjian index (DI)를 이용하였고, 골격적 성숙도는 cervical vertebral maturation stages (CVMS)와 skeletal maturity indicators (SMI)를 이용하여 각각 경추골 성숙도와 수완부골 성숙도를 평가하였다. 그 결과, 남녀 모두 상악 견치의 DI와 CVMS 및 SMI 사이에서 유의하게 높은 상관관계를 나타냈다(p = 0.000). 이 연구를 통하여 상악 견치를 이용한 치아 성숙도 평가는 성장기 아동의 골격적 성숙도를 평가하는 보조적 수단으로 사용될 수 있음을 확인하였다.
