Biocermaics in endodontics

Abstract

Bioceramics are materials which comprise alumina, bioglass, glass ceramics, zirconia, hydroxyapatite and other calcium phosphates. They have been used in dental field as bone filling materials, root repair materials, root-end filling materials, and as endodontic sealers. They have certain advantages as being biological compatible, inert, non-toxicity, dimensionally stable. They have a similarity to the natural minerals part hydroxyapatite which is the main component of hard dental tissues. Bioceramics are characterized by osteoconductive activity bioactivity. In endodontics, they can be generally classified into calcium phosphate; tricalcium; hydroxyapatite based; calcium silicate based or mixtures of both calcium silicate and phosphates. The shift from previously established bioceramics to newly advance formulations is too slow, and there is an urgent demand to boost clinical research.
