Objective:
The aim of this study is to compare the occurrence of pain applying different materials of root canal therapy in vital teeth.
Methods:
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.
Results:
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.
Conclusion:
Root canal treatment applying Cortisomol sealer+gutta-percha can decrease the rate of pain occurrence after root canal filling.
