초록
치근파절은 치아 외상에서 드문 경우로 주로 상악 전치부에서 발생하며, 영구치 외상의 0.5 - 7%에 불과하다. 방사선학적 진단을 통해 수평 치근 파절로 진단된 경우 주변치아에 스플린트하고 경과를 관찰하면서 치관부 파절편의 치수괴사가 발생한 경우 근관 치료를 시행한다. 이 때 칼슘하이드록사이드나 mineral trioxide aggregate (MTA)를 사용할 수 있으며, 본 증례에서는 수평 치근 파절이 발생한 상악 중절치를 MTA로 충전하고 4년간 follow-up하였고, 4년의 follow-up 기간 동안 임상적인 후유증이나 상실 없이 치아를 유지할 수 있었다.
Abstract
Root fracture is a rare case of dental trauma, occurring mainly in the maxillary anterior teeth, and comprise only 0.5 - 7% of traumas affecting permanent tooth. When a horizontal root fracture is diagnosed through radiological examinations, a splint is placed on the adjacent teeth and the progress is observed. If pulp necrosis of the fractured coronal fragment occurs, root canal treatment is performed. Calcium hydroxide or mineral trioxide aggregate (MTA) can be used at this time. In this case report, a maxillary central incisor with a horizontal root fracture was filled with MTA and followed up for 4 years. The tooth was maintained without any clinical symptoms or loss during the 4-year follow-up period.
