Evaluation of the retreatability of bioceramic root canal sealers with various formulations in simulated grooves.

ABSTRACT:

Background

Bioceramic sealers are increasingly used due to their favorable properties, but their strong bonding to dentin complicates retreatment procedure. In addition, canal irregularities such as isthmuses make the complete removal of filling materials more challenging.

Aim

This study aimed to evaluate the retreatability of five bioceramic sealers (BioRoot RCS, Bio-C Sealer, CeraSeal, Endoseal MTA, and AH Plus Bioceramic Sealer) using passive ultrasonic irrigation.

Materials and methods

Sixty human mandibular premolars with straight canals were prepared to size 40/0.04 taper. After longitudinal splitting, standardized grooves were created. The root canals were subsequently obturated using the single cone technique and stored at 37 °C with 100% humidity for 21 days.
