Comparative evaluation of retreatability of three different bioceramic sealers using xylene in root canal retreatment - An cone-beam computed tomography analysis.

Aims: The study aimed to evaluate and compare the efficacy of xylene in dissolving newer bioceramic sealers versus an epoxy resin-based sealer during endodontic retreatment.

Subjects And Methods: Comparing AH Plus to gutta-percha (GP) and CeraSeal (Meta Biomed), Prashanti Bioceramic Sealer, and MTA-Fillapex (Angelus), a total of 72 ( = 18) extracted human permanent teeth with a single root and a single canal were prepared to size F3 and obturated. The ProTaper Universal Retreatment technology was then used to retreat the canals.

Comparative evaluation of removal of oil-based calcium hydroxide intracanal medicaments with two calcium chelators: An cone-beam computed tomography volumetric analysis.

Background: Intracanal medicament (ICM) eliminates remaining bacteria and their toxins that were not removed by chemomechanical preparation during endodontic treatment.

Aim: The aim of this study was to compare and evaluate the removal of ozonated oil-based, silicone oil-based, and distilled water-based ICM with two calcium chelators, i.e.
