초록

이 실험의 목적은 EndoVac®과 EndoActivator®를 이용한 근관세척시 근관 내 접종된 Enterococcus faecalis의 제거 효율을 기존의 irrigation needle을 이용한 방법과 비교 평가하고자 함이다. 발거된 70개의 단근치를 사용하였으며.04 taper ProFile #40까지 근관형성 후 치아를 멸균하고 근관에 E. faecalis를 접종하고 배양하였다. 치아는 근관세척 방법에 따라 20개씩 3개의 실험군과 2개의 대조군으로 나누었다. 2.5% 차아염소산나트륨을 사용하여 근관세척 시행후 일차 표본을 채취하였고, 다시 근관 내에 배양액을 채우고 24시간 동안 배양 후 이차 표본을 채취하였다. 표본은 colony forming units (CFU) 값을 얻기 위해 BHI agar plate에 배양하였다. 일차 표본 결과에서는 모든 실험치아 중 기존의 근관세척 방법을 이용한 하나의 근관에서 양성 배양을 보였다. 이차 표본 결과에서는 EndoVac® 실험군에서 가 장 적은 양성 배양을 보였으며, 기존의 근관세척 방법과 비교시 통계적으로 유의한 차이를 보였다. 실험 결과에 따르면 EndoVac은 근관 내 접종된 E. faecalis의 제거에 있어 기존의 근관세척 방법보다 더 좋은 효율을 보였다.

Abstract

The aim of this study was to evaluate endodontic irrigation methods with EndoVac® and EndoActivator® in the elimination of Enterococcus faecalis from the root canals. Extracted 70 human single-rooted teeth were used. The canals were instrumented by a crown-down technique with .04 taper ProFile to ISO size 40. After the teeth were autoclaved, the canals were inoculated with E. faecalis and incubated for 48 h. The teeth were randomly divided into three experimental groups of 20 teeth each according to canal irrigation methods and two control groups as follows: group 1 - EndoVac®; group 2 - EndoActivator®; group 3 - Conventional needle irrigation method. After canal irrigation using 2.5% NaOCl, first samples (S1) were taken using sterile paper point. And the canals were filled with sterile brain heart infusion (BHI) broth and incubated for 24 h, then second samples (S2) were taken. The samples were cultured on BHI agar plate to determine the numbers of colony forming units (CFU). In first sampling (S1), only one canal of conventional method among the all experimental groups was positive cultured. In second sampling (S2), EndoVac® group showed the least positive culture numbers of E. faecalis. There was statistically significant difference between the EndoVac® and conventional needle irrigation methods in the mean value of Log CFU. According to the results of this study, EndoVac® showed better efficacy than conventional needle irrigation method in the elimination of E. faecalis from the root canal.
