Bioceramics are materials which include alumina, zirconia, bioactive glass, glass ceramics, hydroxyapatite, resorbable calcium phosphates. They have been used in dentistry as root repair materials, bony defects repair, apical filling material, perforation repair and help in tissue regeneration. They have certain advantages like biocompatibility, non toxicity, dimensional stability and bio-inertness. They have a structural similarity to Hydroxyapatite, an intrinsic osteo conductive activity and have an ability to induce regenerative responses in the human body.This review focuses on an overview of Bioceramics, classification and their advantages and also gave a detailed insight into individual bioceramic materials currently used in the fields of endodontics.
