Abstract
Objective: To investigate the clinical effects of Cortisomol paste in the treatment of chronic periapical periodontitis with concomitant sinus and compare it with those of ZnO iodoform paste.Methods: 160 cases of chronic periapical periodontitis with concomitant sinus were chosen,and randomly divided into experimental group(Cortisomol paste) 80 cases,the control group(zinc oxide iodoform paste) 80 cases.The complete periapical curettage was done under local anesthesia in the sinus opening,and the lesions areas was rinsed with 3% hydrogen peroxide saline by turns.The iodoform bandage strip was placed in the sinus when necessary.Then the root canal fillings were competed gutta percha point with Cortisomol paste(the experimental group) or zinc oxide iodoform paste(the control group).Results: 87.5% of patients had no discomfort in the experimental group,while 37.5% in the control group at 7 day after the treatment(P0.05).After 1-year continuous observation,the long-term effect rate of the experimental group was no higher than that of the control group.Conclusion: The Cortisomol paste for the treatment of chronic periapical periodontitis with concomitant sinus is effective and reliable.
