Intratubular Sealer Penetration: Scanning Electron Microscopy Associated with Cathodoluminescence Analysis

The aim of the study was to compare the ability of three endodontic sealers, Endofill (END), AH Plus (AHP), and Sealer Plus BC (SPB), to penetrate dentinal tubules.Forty-five human teeth, single-rooted and previously instrumented mandibular premolars, were randomly divided into three experimental groups (As for PP%, AHP and SPB were similar (SPB showed satisfactory performance in penetrating dentinal tubules, being similar to AHP, and superior to END.Greater penetration of sealer into the dentinal tubules may increase the chance of successful endodontic treatment.
