简要总结
Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in multiple visits (MV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 24 months.
详细描述
The aim of the study was to evaluate postoperative pain and radiographic evidence of periapical healing in teeth with apical periodontitis treated in a single visit with an additional final irrigation using 2% chlorhexidine and to compare the results with conventional multiple-visit root canal treatment (RCT) with an intracanal calcium hydroxide dressing as a control group. Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated by a single operator using the step-back technique with manual instrumentation with 2.5% sodium hypochlorite (NaOCl) and 5% ethylenediaminetetraacetic acid (EDTA) as irrigants. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% chlorhexidine (CHX) before obturation. The other teeth were treated in multiple visits (MV), after completion of root canal instrumentation calcium hydroxide paste was placed into the root canal and root canal obturation was performed in second visit. All patients were recalled and investigated clinically and radiographically for 24 months. Postoperative pain at 24-48 hours and changes in apical bone density indicating radiographic healing were evaluated statistically using the Mann-Whitney U-test followed by the Friedman and the Wilcoxon tests (α=.05).

研究组 & 干预措施
Multiple visit root canal treatment
The teeth were treated in multiple visit (MV) root canal treatment. After completion of root canal instrumentation, calcium hydroxide paste was placed into the root canal. In second visit, all root canals were irrigated with 5% EDTA followed by 2.5% NaOCl before obturation.
干预措施: Calcium hydroxide (Other)
Single visit root canal treatment
The teeth were treated in single-visit (SV) root canal treatment. Final root canal irrigation was performed with 5% EDTA, followed by 2.5% NaOCl and received an additional final rinse with 2% CHX before obturation.
干预措施: NaOCl (Other)
Single visit root canal treatment
The teeth were treated in single-visit (SV) root canal treatment. Final root canal irrigation was performed with 5% EDTA, followed by 2.5% NaOCl and received an additional final rinse with 2% CHX before obturation.
干预措施: CHX (Other)
Multiple visit root canal treatment

结局指标
主要结局
The rate of radiographic healing of the periapical lesion
时间窗: 6,12 and 24 months
Follow-up visits were performed after 6, 12 and 24 months for all patients in order to evaluate radiographic status. Changes in apical bone density indicating radiographic healing was assessed by the periapical index (PAI).
次要结局
- The level of postoperative pain(24 hours and 48 hours)
