뇌병변 환아에서 외상성 손상을 받은 미성숙 영구치의 치험례

Abstract

저자는 뇌병변 장애와 보행장애로 반복적인 외상성 치아손상을 받은 환아의 치료를 시행하였다. 최근 실활된 미성숙 영구치의 계속된 치근 형성을 위해 재생적 근관치료 술식이 많이 시도되어 성공적인 결과를 보이고 있다. 하지만 장애로 인해 반복적인 외상의 위험을 가진 환아에서 치수조직의 재생 보다는 치근단형성술을 통한 치근단의 폐쇄와 근관 충전이 비용과 장기적인 예후의 측면에서 유리한 치료방법이 될 수 있음을 확인하였다. Traumatic dental injury (TDI) is a common problem in children and adolescent. The prevalence of dental trauma among children with disability as compared to healthy children. The TDI of an immature permanent tooth can lead to the loss of pulp vitality and arrested root development. Traditionally, the treatment of choice for necrotic immature tooth is apexification, which is induction of hard tissue barrier at the apex to produce more favorable conditions for conventional root canal filling. This case report describes the treatment of a necrotic immature permanent central incisor with complicated crown fracture. The patient had multiple disabilities (cerebral palsy, congenital heart disease, developmental delay, and gait disturbance) and suffered from She was suffered from repetitive traumatic injury. Apexification and resin restoration was performed under general anesthesia, and favorable clinical results were achieved.
