Registration Number
NCT05006209

Brief Summary

A hundred asymptomatic molar teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in two visits (TV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 48 months

Detailed Description

The aim of the study was to evaluate the 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. 100 asymptomatic molar teeth with periapical lesions were treated using engine-driven nickel-titanium (NiTi) instrumentation with 2.5% sodium hypochlorite (NaOCl) and 5% ethylenediaminetetraacetic acid (EDTA) as irrigants. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% chlorhexidine (CHX) before obturation. The other teeth were treated in two visits (TV), 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 48 months. Changes in apical bone density indicating radiographic healing were evaluated.

One visit root canal treatment with CHXOne visit root canal treatmentThe teeth were treated in one-visit (OV) 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.
Two visit root canal treatment with CHTwo visit root canal treatmentThe teeth were treated in two visit (TV) root canal treatment. After completion of root canal instrumentation, calcium hydroxide (CH) 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.
Primary Outcome Measures
NameTimeMethod
Changes in the size and the PAI score of the periapical lesion48 months

The rate of radiographic healing of the periapical lesion. Follow-up visits were performed for all patients in order to evaluate radiographic status. Changes in apical bone density indicating radiographic healing was assessed using Periapical Index (PAI)(Orstavik 1986) as the scoring system.

Clinical healing according to presence of clinical symptoms48 months

All patients were called for follow up visits. The clinical healing was determined by examining clinical symptoms including presence of pain, tenderness to percussion and palpation, presence of sinus tract or swelling, and mobility.If one of these symptoms occurs, it is considered as failure..
