Chemical composition differences and clinical advantages of bioceramic sealers in contemporary endodontic therapy
Keywords:
Bioceramic sealers, calcium silicate, endodontic obturation, bioactivity, biocompatibility, ion release, antimicrobial effect, dimensional stability, radiopacity.Abstract
Bioceramic sealers have emerged as a transformative development in contemporary endodontic therapy due to their favorable physicochemical properties, bioactivity, and clinical performance. This scientific article aims to analyze the chemical composition of various bioceramic sealers and to evaluate their clinical advantages compared with conventional epoxy resin– and zinc oxide–eugenol–based sealers. The study is grounded in theoretical analysis and interpretation of data derived from published experimental investigations, clinical trials, and dissertation research. Particular emphasis is placed on calcium silicate–based formulations, hydration reactions, ion release mechanisms, antimicrobial properties, dimensional stability, and interaction with periapical tissues. Statistical data from reported studies indicate higher long-term success rates and improved periapical healing outcomes when bioceramic sealers are used in conjunction with modern obturation techniques. Differences in chemical composition—including tricalcium silicate, dicalcium silicate, calcium phosphate monobasic, zirconium oxide, and tantalum oxide—are examined in relation to setting kinetics, radiopacity, solubility, and biological response. The findings support the growing preference for bioceramic sealers as a biologically oriented and clinically reliable material class in endodontic practice.
