The introduction of bioceramic materials has revolutionized modern endodontics by offering superior biocompatibility, bioactivity, sealing ability, and regenerative potential compared with conventional endodontic materials. These materials have become increasingly important in root canal obturation, perforation repair, apexification, pulp capping, regenerative endodontic procedures, and endodontic surgery. Bioceramics interact favorably with biological tissues, promoting hard tissue formation and enhancing periapical healing. This review evaluates the composition, classification, properties, clinical applications, advantages, limitations, and future developments of bioceramic materials in endodontic treatment. Current evidence suggests that bioceramic materials significantly improve treatment outcomes by enhancing sealing efficacy, reducing bacterial leakage, and supporting tissue regeneration. Continued advancements in nanotechnology, regenerative medicine, and bioactive materials are expected to further expand the role of bioceramics in endodontic practice.
