Root canal retreatment

Details and patient eligibility

About

A hundred previously root canal treated asymptomatic single-rooted teeth with periapical lesions were treated in single versus multiple visit root canal retreatment. Half of the teeth were randomly assigned to the one-visit (OV) group. The other teeth were treated in two visits (TV). All patients were recalled and investigated clinically and radiographically for 24 months.

Full description

The aim of the study was to evaluate the radiographic evidence of periapical healing in previously root canal treated teeth with apical periodontitis treated in a single visit and to compare the results with conventional two-visit root canal treatment .100 asymptomatic single rooted teeth with periapical lesions were included. The root canal filling material was removed and reinstrumentation was performed using hand files 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. 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 24 months. Changes in apical bone density indicating radiographic healing were evaluated.

100 participants in 2 patient groups

One visit root canal retreatment

Active Comparator group

Description:

The teeth were treated in one-visit (OV) root canal retreatment. 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.

Treatment:

Other: One visit root canal retreatment

Two visit root canal retreatment

Active Comparator group

Description:

The teeth were treated in two visit (TV) root canal retreatment. 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.

Treatment:

Other: Two visit root canal retreatment
