Abstract

The purpose of this study was to compare the sealing ability of root canal obturation with or without the use of dentin adhesive system. Forty extracted human teeth with one canal were selected and decoronated. The teeth were divided into two Groups. The obturation procedure of Group 1 was the same as that of Group 2 with the exception of dentin adhesive system. Group 2 were obturated with dentin adhesive system, AH-26, and gutta-percha. After obturation, the teeth were immersed in methylene blue solution for 84 hours. The teeth were sectioned horizontally at 1.5 mm (Level 1), 2.0 mm (Level 2) 2.5 mm (Level 3) from the root apex using a low speed microtome. Distance of dye-penetrated surface and total dentinal surface were measured using SigmaScan Pro 5.0, and the ratio of dye-penetrated distance to the total dentinal distance was analyzed statistically by Mann-Whitney U-test. 1. In both groups, the mean leakage ratio was decreased cervically. 2. At level 1, there was no significant difference between group 1 and group 2 (p > 0.05). 3. At level 2 and 3, group 1 showed significantly higher mean leakage ratio than group 2 (p < 0.05). The results suggest that using dentin adhesive system in root canal obturation procedure reduces the apical microleakage.

이 연구의 목적은 상아질 접착제의 사용 여부에 따른 근관 밀폐효과를 비교 평가하기 위해 40개의 단근치를 근관 성형 후 20개씩 두군으로 나누었다. 1군은 근관 충전시에 상아질 접착제를 사용하지 않았으며 2군은 상아질 접착제를 사용하였다. 근첨에서 1.5 mm (Level 1), 2.0 mm (Level 2), 2.5 mm (Level 3) 떨어진 부위의 평균 누출률을 측정하였다. 1. 두군의 평균 누출률은 치경부로 향하면서 감소하였다. 2. Level 1에서 1군과 2군의 평균 누출률은 차이가 없었다 (p > 0.05) .3. Level 2와 3에서 2군의 평균 누출률은 1군보다 낮았으며, 통계학적으로 유의차를 나타내었다 (p < 0.05) .연구결과 상아질 접착제를 사용하여 근관 충전하는 경우 치근단 누출을 감소시킬 수 있을 것으로 판단된다.
