N2 - Powder jet deposition (PJD) is a coating process using accelerated particles. In this process, accelerated ceramic particles are impacted on a substrate, and fractured particles partly adhere to it. We have proposed to apply this process to dental treatment. In this study, the effects of the diameter (dg) and the velocity (vg) of a hydroxyapatite particle on PJD process to human enamel were investigated by using a smoothed particle hydrodynamics (SPH) method. Optimized conditions were clarified through the SPH simulations, and PJD experiments were conducted under the obtained conditions. It was found that the surface of the enamel substrate was partly removed when the mean particle diameter dg = 4.65 μm and the mean particle velocity vg = 250 m/s, and coated layers were formed on the human enamel substrates when dg = 4.65 μm and vg = 200 m/s, or dg = 3.18 μm and vg = 200, 250 m/s.
