초록

이 실험의 목적은 Resilon으로 근관충전된 치아에서 자가산부식전처리제에 따른 치근단 미세누출을 평가하고자 함이다. 70개의 단근치를 사용하였고 .04 Taper ProFile을 사용하여 ISO #40까지 근관성형 하였다. 치아는 근관충전 재료와 자가산부식 전처리제에 따라서 15개씩 4개의 실험군과 5개씩 2개의 대조군으로 나누었다. 실험 치아는 치아 장축에 평행하게 잘라내어 염색액의 최대 침투 길이를 측정하였다. 통계분석은 One-way ANOVA test로 분석하였으며 Scheffe test로 사후검정 하였다. 실험결과 자가산부식전처리제를 사용한 2, 3, 4군 사이에서는 통계적으로 유의한 차이를 나타내지 않았다. 그러나 1군과 4군 사이에서는 통계적으로 유의한 차이가 나타났으며 (p < 0.05), 1군에서 가장 적은 치근단 미세누출을 나타냈다. 이 실험 결과에 따르면 Resilon으로 근관충전을 한 치아는 gutta percha와 $AH26^{(R)}$으로 근관충전한 치아와 비교했을 때 더 좋은 치근단 밀폐를 나타내지 않는다는 결론을 얻었으며, Resilon을 사용하여 근관충전을 한 경우에 자가산부식 전처리제의 차이에 따른 치근단 밀폐효과의 차이를 보이지 않는다는 결론을 얻었다.

The purpose of this study was to compare the apical micro leakage in root canal filled with Resilon by several self-etching primers and methacrylate-based root canal sealer. Seventy single-rooted human teeth were used in this study. The canals were instrumented by a crown-down manner with Gate-Glidden drills and .04 Taper Profile to ISO #40. The teeth were randomly divided into four experimental groups of 15 teeth each according to root canal filling material and self-etching primers and two control groups (positive and negative) of 5 teeth each as follows: group 1 - gutta percha and $AH26^{(R)}$ sealer: group 2 - Resilon, $RealSeal^{TM}$ primer and $RealSeal^{TM}$ sealer: group 3-Resilon, Clearfil SE $Bond^{(R)}$ primer and $RealSeal^{TM}$ sealer group 4-Resilon, $AdheSe^{(R)}$ primer and $RealSeal^{TM}$ sealer. Apical leakage was measured by a maximum length of linear dye penetration of roots sectioned longitudinally by diamond disk. Statistical analysis was performed using the One-way ANOVA followed by Scheffe's test. There were no statistical differences in the mean apical dye penetration among the groups 2, 3 and 4 of self-etching primers. And group 1, 2 and 3 had also no statistical difference in apical dye penetration. But, there was statistical difference between group 1 and 4 (p < 0.05). The group 1 showed the least dye penetration. According to the results of this study, Resilon with self-etching primer was not sealed root canal better than gutta precha with $AH26^{(R)}$ at sealing root canals. And there was no significant difference in apical leakage among the three self-etching primers.
