근관치료는 치아우식증이나 외상 등으로 인해 손상된 치아의 기능을 회복시키고 원래의 형태를 유지시켜주는 치료이다. 따라서 그 치료 과정에는 치수 및 치근단조직을 손상시키고 통증을 유발하는 세균 감염이나화학적, 물리적 자극을 제거하는 술식이 필수적이며,이러한 과정을 통해 통증이 사라지고 치료전에 존재하던 치근단 병소가 치유되는 것이 주기적인 관찰 과정에서 확인되면 그 치료는 성공적이라고 할 수 있다. 이는치근 성장이 완성되기전 손상을 입어 치근단 병소가 생기고 치수가 괴사되는 미성숙 영구치에서도 동일하게적용되는데 이런 경우 근첨형성술 (apexification)을수십년간 통상적으로 적용해 왔는데 최근에는 근관치료에도 재생의 개념이 도입되어 단지 치근단 병소의 치유만을 치료의 목적으로 하는 것이 아니라 치근의 재생까지도 기대하고 치료하는 경우가 증가하게 되었다1~3). 치근발육의 목적이면 apexogenesis와 같은 개념이아닌가 하고 생각할 수 있지만 apexogenesis는 근첨형성술을 시행한 다음 우연하게 근단부의 완성이 확인되는 경우인 반면 Regenerative endodontic procedure (REP)라고 불리는 재생술식은 치근의 정상적인 발육을 예상하고 적극적으로 치료에 개입하는치료과정이라고 할 수 있다. 따라서 본 논문은 REP를시행하는 rationale와 REP 술식과 REP에 사용되는MTA (mineral trioxide aggregate)의 올바른 적용방법을 확인하여 손상받은 미성숙 영구치 근관치료에 재생술식이 올바르게 적용되도록 하는 것이 그 목적이다.
