Abstract
Abstract An in vitro study involving 66 single–rooted human teeth was performed. The teeth were divided into 3 groups: control group, root canals instrumented and irrigated with distilled water; experimental group A, root canals instrumented and irrigated with 15% EDTA; and experimental group B, root canals instrumented and irrigated with 5% sodium hypochlorite. All canals were filled with laterally condensed gutta‐percha and Diaket® A. Radiographs were taken mesiodistally and buccolingually and the number of lateral canals filled in the various teeth was counted. The group treated with 15% EDTA showed a significantly larger number of filled lateral canals than the groups irrigated with distilled water or sodium hypochlorite.
