The aim of this study is to compare the occurrence of pain applying different materials of root canal therapy in vital teeth.
288 vital teeth were divided into 4 groups, Cortisomol sealer+gutta-percha and Vitapex+gutta-percha were used respectively in 2 groups of one time method; while Cortisomol sealer+gutta-percha and Vitapex+gutta-percha were used after 24-48 hours drainage in the other 2 groups. The occurrence of pain after 1 week was recorded.
In all treated teeth,the occurrence rate of self-healing pain after root canal therapy was 22.6%, the occurrence rate of non-self-healing was 2.08%; in the groups of one time method,the occurrence rate of pain using Cortisomol was lower than the group using Vitapex with significant difference(P<0.01); while in the groups of root canal filling after drainage,the occurrence of self-healing pain in the group using Cortisomol was lower than the group of using Vitapex without significant difference(P>0.05);the pain occurred within 72 hours in most of the teeth.
Root canal treatment applying Cortisomol sealer+gutta-percha can decrease the rate of pain occurrence after root canal filling.
本研究旨在比较在活髓牙根管治疗中应用不同材料时疼痛的发生率。
将288颗活髓牙分为4组，其中2组采用一次法分别使用Cortisomol封闭剂+牙胶尖和Vitapex+牙胶尖；另外2组在引流24 - 48小时后使用Cortisomol封闭剂+牙胶尖和Vitapex+牙胶尖。记录1周后疼痛的发生情况。
在所有治疗牙齿中，根管治疗后自愈性疼痛发生率为22.6%，非自愈性发生率为2.08%；在一次法组中，使用Cortisomol的疼痛发生率低于使用Vitapex的组，差异有统计学意义（P<0.01）；而在引流后根管充填组中，使用Cortisomol的组自愈性疼痛发生率低于使用Vitapex的组，但差异无统计学意义（P>0.05）；大多数牙齿的疼痛在72小时内发生。
应用Cortisomol封闭剂+牙胶尖进行根管治疗可降低根管充填后疼痛的发生率。
