초록
목적: 근관 치료에 사용된 실러의 양과, 재치료용 NiTi 파일이 근관충전재의 제거 효율에 미치는 영향을 알아보고자 하였다. 연구 재료 및 방법: 발거된 소구치 중 단일 근관을 가지는 치아를 대상으로 하였다. #40/.06까지 근관 형성을 한 후, 무작위로 4 그룹으로 분류하였다. 근관충전재 중 실러가 차지하는 양을 다르게 하기 위해 그룹 별로 .06 taper 또는 .04 taper 거타퍼차를 칼슘실리케이트 실러인 Ceraseal과 함께 사용하여 single-cone 충전법으로 충전하였다. 그룹 별로 재치료용 NiTi 파일로는 ProTaper Universal Retreatment system (PTUR) 또는 Hyflex Remover (HR)를 사용하였다. 충전재 제거에 걸린 시간, 치근단 방출 잔사량, 근관 내의 충전재 잔존량을 측정하고 비교하였다. 결과: 근관치료에 사용된 실러의 양은 충전재 제거 효율에 영향을 미치지 않았다. HR 그룹은 PTUR 그룹보다 빠르게 충전재를 제거하였다. 치근단 방출 잔사량과 근관충전재 잔존량은 재치료용 NiTi 파일의 종류에 따라 유의한 차이를 보이지 않았다. 결론: 근관치료에 사용된 실러의 양은 제거 효율에 유의한 영향을 미치지 않았다. HR는 기존의 PTUR보다 빠르게 충전재를 제거했으며, 다른 제거 효율은 차이가 없었다.
Abstract
Purpose: The efficacy of the amount of sealer in the root canal and two retreatment NiTi file systems in removing filling materials. Materials and Methods: Extracted premolars with a single root canal were selected for this study. After access opening and root canal preparation up to size #40/.06, the specimens were randomly divided into four groups. Gutta percha (GP) tapers of .06 or .04 were used for each group and filled using a single-cone filling technique with CeraSeal, a calcium silicate-based sealer. Each group was retreated either using the ProTaper Universal Retreatment System (PTUR) or the Hyflex Remover (HR). The time taken to remove the filling material, the amounts of apically extruded debris, and canal cleanliness were measured and compared. Results: The amount of sealer did not affect the efficiency when removing the filling materials. However, the filling material was removed faster in the HR group than in the PTUR group. Two types of NiTi files showed similar retreatment effects in the amounts of apically extruded debris and in the degree of canal cleanliness. Conclusion: The amount of sealer in canal filling had no significant effect on retreatability. Retreatment with HR removed filling materials is faster than PTUR. There was no difference in other removal efficiencies according to the type of retreatment NiTi file.
