Setting reaction of new bioceramic root canal sealers

Abstract

Objective: This study aimed to evaluate setting reaction and the time of three bioceramics (Endosequence, iRoot-SP, and Smartpastebio) compared with glass ionomer (ActiV-GP) root canal sealers. Materials and methods: Setting reaction was tested using Fourier Transform Infrared Spectroscopy and X-ray Diffraction; setting time was measured using a Vicat needle. Results: Three-bioceramic sealers composed of calcium hydroxide, calcium phosphate, calcium silicate, silicon oxide, and zirconium oxide. During their setting, calcite and calcium phosphate silicate were detected. Their setting took longer time than ActiV-GP that have aluminum polyacrylate and calcium phosphate silicate in set mass. Conclusions: Bioceramic sealers took longer time to set than expected.
