초록

유치열기의 3급 부정교합은 조기 치료가 추천되지만 정확한 진단이 쉽지 않다. 3급 부정교합의 골격성 특성과 치아 발육상태 사이에 연관성이 있다면 골격성 3급 부정교합의 감별 진단을 위한 평가 항목으로 치아성숙도가 활용될 수 있을 것이다. 본 연구는 유치열기의 골격성 혹은 비골격성 3급 부정교합으로 진단받은 환아를 대상으로 치아 석회화도 및 제 1대구치의 맹출률을 비교, 분석하여 상하악의 치아성숙도 차이가 유치열기 3급 부정교합의 감별 진단시 평가 항목으로 사용될 수 있는지 알아보기 위한 목적으로 시행되었다. 전치부 반대교합을 주소로 부산대학교 치과병원 소아치과에 내원한 유치열기 아동 중 비골격성 3급 부정교합군 18명과 골격성 3급 부정교합군 34명을 연구대상으로 선정하였다. 파노라마 방사선사진상에서 치령 및 제1대구치 맹출률을 비교, 분석하여 다음과 같은 결과를 얻었다. 골격 및 성별에 따른 역령과 치령의 차이는 존재하지 않았으며, 두 군 모두 역령에 비해 치령이 높게 나타났다(p < 0.05). 비골격성군과 골격성군의 상하악 맹출률의 차이는 각각 16.53%, 18.91%로 통계학적으로 유의한 차이를 보여(p < 0.05), 3급 부정교합의 감별 진단을 위한 평가 항목으로서 제1대구치 치아성숙도의 활용 가능성을 시사한다.

Early treatment is recommended for class III malocclusion in the primary dentition, though it is difficult to diagnose correctly. It was recommended dental maturation can possibly be used to make a differential diagnosis of skeletal class III malocclusion. This study aimed to compare dental maturation of first molars in children with skeletal or non-skeletal class III malocclusion in the primary dentition and to determine if dental maturation could be used to make a differential diagnosis of class III malocclusion. Among the children visiting the department of pediatric dentistry in Pusan National University Dental Hospital for anterior crossbite in the primary dentition, 18 were categorized into the non-skeletal class III malocclusion and 34 into the skeletal class III malocclusion. Panoramic radiographs were used to make comparative analysis of dental age and the eruption rate of the first molars. The following results were obtained. No difference was found between chronologic and dental age by the skeletal features or gender, with the latter being older than the former (p < 0.05). The discrepancies in eruption rate of first molars were significantly different between skeletal (18.91%) and non-skeletal groups (16.53%) (p < 0.05). This result implies that maturation of the first molars might be used to make a differential diagnosis of class III malocclusion.
