Abstract
Using a powder-jet-deposition process, a thick hydroxyapatite (HAp) film can be created on a human tooth surface. Two different types of HAp particles, calcinated at 1,200 and 1,300°C, were used. The HAp particle was mixed with nitrogen as the carrier gas to form an aerosol flow and then accelerated and blasted from the nozzle onto the enamel substrate at room temperature and atmospheric pressure. HAp particles in the deposited film were tightly packed. There was no gap between the HAp film and the enamel substrate. The bonding strength of the HAp film is almost the same as the composite resin on the enamel.
