Comparison between differently synthesized hydroxyapatite composites for dentistry applications

Abstract

Hydroxyapatite and its composites have applied in several biomedical applications as a bioceramic. This research used to examine chemical and structural suitability of newly synthesized Eppawala hydroxyapatite composite varieties as dental filling material, by comparing and contrasting them with human tooth as well as commercially available glass ionomer cement (GIC), used in dentistry applications. Commercially available 2-hydroxyethyl methacrylate monomer used to reinforce solid state sintered and sol gel synthesized hydroxyapatite ceramic to prepare its composites and their physical, chemical properties were compared. Results show there is a close similarity between synthesized products and human tooth while credenting high thermal stability, good crystalline, and porous properties than the commercial product. Finally, study concluded newly synthesized composites can be applied directly as a substitution for human tooth while having different properties from each other.
