不同根管充填技术对椭圆形根管的根尖封闭效果
A comparison of apical sealing ability of different root canal obturation techniques in oval root canals
摘要
Abstract
Objective To investigate the effect of different root canal obturation techniques on apical sealing in oval root canals. Methods 120 recently extracted human premolars with single oval canal were randomly divided into 6 groups, including single point obturation, warm gutta percha vertical condensation, cold lateral condensation obtura-tion method combined with different root canal sealers (iRoot SP or AH-Plus). There're six groups in total, including sin-gle point iRoot group, warm gutta percha iRoot group, cold gutta percha iRoot group, single point AH group, warm gutta percha AH group, cold gutta percha AH group. Results Root depth of dye penetration in warm gutta percha iRoot group and warm gutta percha AH group were significantly lower than group single point iRoot group and single point AH group (P<0.05), and root depth of dye penetration of warm gutta percha iRoot group, cold gutta percha iRoot group was less than warm gutta percha AH group, cold gutta percha group (P<0.05), but there was no statistic difference be-tween other groups (P > 0.05). Conclusion In root canal treatment, warm gutta-percha condensation technology can make the oval canal root achieve better sealing effect, using iRoot SP is better than using AH-Plus.关键词
