Context: Reduction of the bacterial populations to levels compatible with periradicular tissue healing is the primary microbiological goal of the endodontic treatment of teeth with apical periodontitis. The number of visits required to treat teeth with apical periodontitis represents one of the most debatable issues in endodontics. Objectives: The objective of this study was to compare and evaluate the clinical and radiographic outcome of single- versus two-visit pulpectomy treatment in primary teeth with apical periodontitis at the end of 6-month healing period. Settings and Design: A parallel group, double-blind, randomized controlled trial was carried out in 64 children aged 4-8 years. Nonvital primary teeth with apical periodontitis with enough coronal structure were selected. Sixty-four children were assigned randomly into two groups (32 children each) by block randomization, and allocation concealment was done with closed envelop method. Methods and Materials: Group I underwent single-visit pulpectomy followed by obturation with zinc oxide eugenol (ZOE). Group II underwent conventional two-visit pulpectomy with intracanal calcium hydroxide, followed by obturation with ZOE. Postoperative clinical and radiographic evaluation was carried out at 1, 3, and 6 months after the end of the treatment. Statistical Analysis Used: The data were analyzed by Wilcoxon's signed rank test, Mann-Whitney U-test, and Friedman test. Results: There was no statistically significant difference in clinical and radiographic outcomes in both the groups at the end of 6-month healing period. Conclusion: Single-visit pulpectomy can be considered as a viable option for the treatment of primary teeth with apical periodontitis.
