The bond strength of endodontic sealers to root dentine exposed to different gutta-percha solvents

Aim To evaluate the effects of various gutta‐percha solvents on the push‐out bond strength of several root canal sealers on root dentine. Methodology The root canals of 210 single‐rooted human teeth were prepared with the ProTaper System (Dentsply Maillefer, Ballaigues, Switzerland) up to a master a...

Summary:Aim To evaluate the effects of various gutta‐percha solvents on the push‐out bond strength of several root canal sealers on root dentine. Methodology The root canals of 210 single‐rooted human teeth were prepared with the ProTaper System (Dentsply Maillefer, Ballaigues, Switzerland) up to a master apical file size of F4, and the following variables evaluated for bond strength: solvent type (chloroform, eucalyptol and orange oil), time (2 and 5 min), sealer type (AH Plus, MTA Fillapex and Sealapex) and root thirds (coronal, middle and apical). After canal filling, three 1‐mm‐thick slices were obtained from each root sample, and the bond strength of the test materials was measured using a push‐out test set‐up at a cross‐head speed of 1 mm min−1. The data were analysed using four‐way factorial anova (P = 0.05). Results Bond strength was significantly affected by solvent type and time (P
