Microstructural and elemental characterization of novel bioactive glass bioceramic sealer using Fourier transform infrared and X-ray diffraction analysis.

Abstract

Introduction: The success of endodontic therapy is primarily determined by effective root canal obturation and complete bacterial eradication. Recently, bioceramic sealers have gained significant attention in root canal treatments due to their bioactive and biocompatible properties. This study aims to characterize a novel bioactive glass-based bioceramic sealer, utilizing X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy to evaluate its bioactivity and hydroxyapatite-forming potential.

Methodology: Characterization of the material involved XRD to identify crystalline phases, while FTIR was employed to detect functional groups. The synthesized powder was sieved and pressed into discs for FTIR analysis, with XRD analysis conducted on the sieved powder.

Results: XRD analysis revealed nanoscale crystalline features, indicating a complex multiphase composition. FTIR identified silicate networks, hydroxyl groups, and carbonate species, supporting the material's bioactivity and its potential to form hydroxyapatite.

Conclusion: The bioactive glass-based bioceramic sealer shows strong potential for dental and orthopedic use. Its nanoscale crystalline structure and silicate network enhance bioactivity and mechanical strength, while hydroxyl and carbonate groups promote tissue integration and hydroxyapatite formation. Further in vivo and in vitro studies are needed to confirm its clinical effectiveness.
