Abstract

Pre-eruptive intracoronal resorption (PEIR) is a rare radiolucent lesion often located within the dentin and adjacent to the dentin-enamel junction, underneath the occlusal aspect of the crowns of unerupted teeth. The treatment approaches for these lesions involved with unerupted teeth have been known as to be relatively simple; depending on the extent of resorption, follow-up or restoration can be performed after surgical exposure. However, once the tooth is exposed to the oral cavity after eruption, it becomes highly vulnerable to the development of carious lesions. Thus, immediate intervention is required in such cases; failure to address it may result in the need for more complex treatments including endodontic therapy. The aim of this case report was to describe the characteristics of PEIR and the clinical management of the impacted immature permanent teeth diagnosed with PEIR.

맹출 전 치관 내 흡수(pre-eruptive intracoronal resorption; PEIR)는 미맹출치 치관의 법랑상아경계하방에 위치한 방사선 투과상의 흔치 않은 병소이다. 맹출 전 치아에서의 PEIR은, 흡수 진행속도에 따라 외과적 노출술 후 수복 혹은 지속적 관찰로 치료가능하다. 하지만 맹출 후에는 우식 병소 발달의 위험이 높아 임상가의 대처가 늦을 경우 근관치료 등을 포함하는 심화된 수복치료를 진행하여야 한다. 본 증례는 어린이에서 PEIR로 인해 감염된 미성숙 영구치의 임상적 특징 및 치료에 관하여 보고하고자 한다.
