Objective:To evaluate the effect of Vitapex in root canal therapy (RCT) for infected permanent teeth.Methods:159 permanent teeth with chronic periapical periodontitis were treated by RCT, and the canals were filled with Vitapex (in 54 teeth),ZOE (in 52 teeth) and ZOE plus iodoform (in 53 teeth) respectively.The effects were evaluated by clinical and radiological observation.Results:The ratio (%) of apical tissue reaction in 3 days following RCT in the group of Vitapex,ZOE and ZOE plus iodoform was 14.8,59.6 and 50.9 (P0.05) respectively.Conclusion:Vitapex is effective in the treatment of infected root canals.
