Bioceramics are ceramic materials specifically designed for medical and dental use. Bioceramics are materials composed of nanosphere particles of tricalcium silicate, tantalum pentoxide, dicalcium silicate, alumina and zirconia, bioactive glass, calcium silicates, hydroxyapatite. These materials presents biocompatibility, bioactivity, resistance to leakage, sealing ability and biomineralization activity. The presence of calcium silicate in these materials can reduce inflammation and induce tissue repair.The advent of bioceramics materials increases the possibility of reparative and regenerative processes in dentistry, and more precisely, in endodontics.
