Abstract

Molar-incisor malformation (MIM) is a newly reported dental anomaly with molar root deformity and incisor crown defects. MIM-affected teeth may cause severe pain with no apparent tooth caries. Since the affected molars clinically appear normal, radiographs are recommended for accurate diagnosis on the first visit. Since MIM-affected patients are in mixed dentition, timely and appropriate interventions are needed to avoid unnecessary pain and complicated clinical issues. This report was written to describe two patients who had MIM in early mixed dentition and report their 2-year follow-ups.

대구치-절치 형태이상(MIM)은 비교적 최근에 보고되고 있는 치아의 형태 이상으로, 주로 제1대구치의 치근, 제2유구치의 치근, 상악 중절치의 치관에 형태이상이 나타난다. MIM을 일으키는 원인에 대해서는 아직 정확하게 밝혀진 바가 없으나, 공통적으로, 조산을 포함한 생 후 1 - 2년 이내에 발생한 의학적 병력을 가진다. MIM에 영향을 받은 제1대구치는 임상적으로 정상적인 치관 형태를 가지므로, 정확한 진단을 위해서는 방사선학적 검사가 꼭 필요하다. 주로 대구치 부위의 극심한 통증과 붓기를 주소로 내원하여 발견되는 경우가 많으며, 염증이 심하지 않고, 치근의 형태 이상이 비교적 양호한 경우에는 근관치료를 시도해 볼 수 있다. 그러나 치근주위 염증이 상당히 진행되어 광범위한 치조골 소실이 관찰되는 경우 발치가 불가피하다. 발치를 해야 하는 경우에는 발치 시기와 제3대구치의 존재 여부를 고려해야 하며, 추후 안정적인 교합을 위해서 적절한 공간 관리와 장기적인 계획이 필요하다. MIM 환자들은 혼합치열기에 있으므로, 정확한 진단과 시기에 맞는 적절한 치료가 중요하다. 이번 증례에서는 두 명의 MIM 어린이의 치료과정과 치료 후 2년의 경과에 대하여 보고하는 바이다.
