Abstract
The invention relates to a process for the effective removal of both hard and soft decay using micro air abrasion dentistry. The process uses a composition which is treated to make it biologically inactive. It comprises at least 95% alumina of a certain particle size distribution and is optimized to remove both hard and soft decay, including carious enamel, carious dentin, stains, calculus, materia alba, organic plug, glass ionomer, composites, resin restoratives, cementum and spent amalgam. Over 50% of the abrasive has particle sizes ranging from 15 to 45.mu. with an average particle size of 27.5.mu.. Other unique features of the abrasive include the addition of color and flavor agents to detect the presence of caries and increase patient enjoyment, respectively.
