Comparison of clinical effect between two different canal filling pastes

Objective To compare the clinical result between two different canal filling paste for curing pulp necrosis and （or） chronic periapical periodontitis. Methods, 164 patients with 198 teeth were divided into experimental group and control group randomly. Root canals of the experimental group were filled with gutta point plus cortisomol paste in a lateral pressure way. Root canals of the control group were filled with gutta percha point plus zinc oxide-engenol paste in a lateral pressure way. The curative effect of the two groups were observed after canal filling. Results The difference of the curative effect was significant between two groups. The curative effect of experimental group was significantly better than that of the control group. Conclusions The use of cortisomol paste for one-time root canal therapy is obviously effective in relieving pain after-operation. Cortisomol paste was worth being applied extensively in clinical practice.
