Hydroxyapatite-based Bioceramic Dental Inserts as Dentin Substitute

Abstract

Tooth caries presents one of the most common diseases worldwide, and its treatment involves removal of the decayed tooth structure, and the cavity restoration using restorative dental materials. Resin based composites (RBCs) are the most commonly used restorative material in practice owing to their great aesthetic appearance allowing the clinicians to adapt the nuance of the restoration to the patient’s tooth color. However, the RBCs harden by the polymerization of monomers that leads to the polymerization shrinkage of the restoration, leaving the micro-gaps at the teeth-restorations interface which allows the secondary caries formation.
