Abstract
A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.
