Research Abstract

This study aimed to create a thick hydroxyapatite (HA) film on the surface of a human tooth via a powder jet deposition (PJD) device for dental handpieces, and to examine the microstructural and mechanical properties of the HA film. The HA particles in the deposited film were densely packed, and the three-dimensional microstructure and the rough surface of the HA film were unchanged after thermal cycling. There were also no significant differences in the hardness and the bonding strength between the HA film before and after thermal cycling.
