초록

이 논문의 목적은 골 성숙도와 치아의 성숙도를 골격적 부정교합에 따라 관련성을 알아보는 것이다. 6세에서 14세에 이르는 총 192명의 환자(89명의 남자, 103명의 여자)를 대상으로 하였으며 측모 두부 방사선 사진, 파노라마 방사선 사진, 수완부 방사선 사진을 사용하였고 심한 질환을 가진 경우는 제외하였다. 통계는 이분법, chi-square, logistic regression analysis, independent t-test를 사용하여 분석하였다. 견치, 제1대구치, 제2대구치의 석회화는 골 성숙도와 연관성(p < 0.05)을 보였고 또한 골 성숙도가 높은 경우, 여자어린이 일 경우가 11.43배 높았다(p < 0.001). class II 부정교합일 경우, 견치, 제1소구치, 제1대구치, 제2대구치의 치아 석회화 정도가 class III 부정교합자에 비해 높았다(p < 0.05). 치아의 석회화와 골 성숙도의 연관성은 높았으며 class II와 class III 부정교합환자의 치아의 성숙도는 치아에 따라 다른 성숙도를 보였다.

The purpose of this study was to compare skeletal maturity index and dental developmental stages based on skeletal malocclusion. A total of 192 patients (89 male and 103 female) between 6 to 14 years old were selected for this study and underwent cephalograms, panorama radiographs, and hand-wrist radiographs. Any syndromic cases were excluded. Selected clinical parameters were dichotomised for statistical analysis. Chi-square, logistic regression analysis, and independent t-tests were used for the statistical evaluation. Canine, first molar, and second molar calcification were significantly associated with skeletal maturity in the logistic regression model (p < 0.05). In addition, patients who had higher skeletal maturity index were 11.43 times more likely to be female than those who had lower skeletal maturity index (p < 0.001). The patients with skeletal class II malocclusion displayed significantly higher dental developmental stage in canines, first premolars, first molars, and second molars than the patients with class III malocclusion (p < 0.05). The dental developmental stage of the patients was significantly associated with skeletal maturity. In addition, there was a significant difference between class II and class III malocclusion with some types of tooth calcification.
