Efficacy of New Bioceramic Materials in Root Canal Obturation.

Background: The efficacy of root canal obturation is crucial for the long-term success of endodontic treatments. Recently, bioceramic materials have gained attention due to their superior biological and physical properties compared to traditional materials.

Materials And Methods: In this study, 60 extracted human teeth with single canals were randomly divided into three groups ( = 20) based on the obturation material used: Group A (EndoSequence BC Sealer), Group B (BioRoot RCS), and Group C (Conventional Gutta-Percha with AH Plus Sealer).

Comparative Evaluation of Smear Layer and Debris on the Canal Walls prepared with a Combination of Hand and Rotary ProTaper Technique using Scanning Electron Microscope.

Introduction: The effect of smear layer and debris on the success rate of endodontic treatment has not yet been definitely determined. So the present study was aimed to evaluate the amount of smear layer and debris on the canal walls prepared with a combination of hand and rotary ProTaper technique using NaOCl and ethylenediaminetetraacetic acid (EDTA) alternately as root canal irrigants using scanning electron microscope (SEM).

Materials And Methods: Eighty intact freshly extracted human permanent mandibular premolar teeth were collected and randomly divided equally into four groups.
