Abstract

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.

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.
