Abstract

Pre-eruptive intracoronal resorption (PEIR) is a developmental defect in the crown of a pre-eruptive tooth. The purpose of this study was to investigate the relationship between the size of the pre-eruptive buccal pit radiolucency, which is suspected as PEIR on a panoramic radiography, and the need for restoration after the eruption of a mandibular first molar. The experimental group included 35 mandibular first molars, in which lesions requiring definite restoration were observed during eruption. The control group consisted of 64 sound mandibular first molars after eruption. The sex, age, tooth position, tooth formation stage, size of the pre-eruptive buccal pit radiolucency, and restoration methods in the experimental group and control group were examined. Compared with the control group, the experimental group showed a statistically significant difference in the size of the buccal pit before eruption. The buccal pit size for predicting the need for restoration was further examined by receiver operating characteristic curve analyses, and the area under the curve was $0.813{\pm}0.047$. If radiolucency is observed at the buccal pit of the mandibular first molar before eruption, periodic observations and post-eruption examinations are required.

Pre-eruptive intracoronal resorption (PEIR)은 맹출 전 치아의 치관 내에서 나타나는 발달 상의 결함을 의미한다. 본 연구의 목적은 파노라마 방사선 사진의 미맹출 하악 제1대구치 협측 소와에서 PEIR로 의심되는 방사선 투과상과 맹출 중인 하악 제1대구치에서 협측소와의 수복 필요성과의 관계를 조사하는 것이다. 실험군은 맹출 중일 때 협측 소와에 한정된 수복이 필요한 병소가 관찰되었던 35개의 하악 제1대구치를 대상으로 하였고, 대조군은 맹출 후 건전했던 하악 제1대구치 64개를 포함하였다. 실험군은 대조군에 비하여 맹출 전 파노라마 방사선 사진에서 측정된 협측 소와의 크기가 통계적으로 유의하게 컸다. 실험군 내에서 성별, 나이, 치아형성단계, 수복 방법에 따른 협측 소와 크기의 유의한 차이는 없었다. Receiver operating characteristic 커브를 그렸을 때, 커브 아래 면적이 $0.813{\pm}0.047$으로 방사선 사진 상의 협측 소와 크기를 근거로 수복 필요성을 예측했을 때 중등도의 정확성을 보였다. 파노라마 방사선 사진에서 맹출 전 하악 제1대구치의 협측 소와 부위에서 방사선 투과상이 관찰되는 경우 임상적으로 PEIR을 의심하고 주기적인 관찰과 맹출 후 검사가 필요할 수 있다.
