초록
상악 견치가 매복 시에 종종 인접 전치 치근의 치근흡수가 나타난다. 심각한 전치의 치근 흡수는 치아의 장기적인 예후를 불량하게하기도 한다. 이 연구의 목적은 3차원 영상을 이용하여 상악 견치에 의한 전치의 치근 흡수를 관찰하고 관련된 요인을 분석하는 것이다. 연구 대상자는 상악 견치 매복을 가진 65명의 어린이로 총 88개의 치아에 대해 65개의 cone-beam computed tomography 영상을분석하였다. 그 결과, 상악 견치의 치근 발달 정도와 치근단공의 폐쇄 및 치관의 근원심적인 위치가 중절치의 치근흡수와 유의한 관계를 나타내였다. 측절치의 치근 흡수 여부는 환아의 성별, 나이, 상악 견치의 협설 위치, 수직적 위치에 영향을 받았다. 상악 견치 치배의 확장은 중절치와 측절치의 치근 흡수 여부와 유의한 관계가 없어, 치배의 확장이 치근 흡수에 직접적인 역할을 하지 않는 것으로나타났다. 상악 견치의 매복 시에 전치의 치근 흡수는 예측하기 어렵기 때문에, 3차원 영상을 이용한 조기 진단이 필요하다.
Abstract
Root resorption of the permanent maxillary incisors can occur due to ectopic eruption of the permanent canines. Severe root resorption threatens the long-term survival of the affected incisors. The aim of the present study was to identify risk factors for root resorption of the maxillary incisors associated with impacted maxillary canines. In the present study, we retrospectively analyzed the Cone-Beam Computed Tomography (CBCT) scans of 65 children and adolescents with ectopically erupting maxillary canines (total of 88 impacted canines). Root resorption of central incisors was significantly associated with the mesiodistal position and root development of the adjacent canine. Root resorption of lateral incisors was significantly associated with sex, age, and the buccolingual and vertical position of the adjacent canine. However, enlargement of the dental follicle was not significantly associated with root resorption of adjacent incisors. Although incisor resorption is difficult to diagnose and predict, our findings suggest that changes in the dental follicles of the erupting maxillary canines do not cause resorption of the adjacent permanent incisors. CBCT should be utilized to ensure early diagnosis of impacted canines and precise evaluation of incisor root resorption.
