Air abrasion works on the principle of kinetic energy and utilizes alumina particles to abrade the surface. Alumina particles are effective in cutting but could be toxic if inhaled. Therefore this book explains a study in which bioactive glasses were used to successfully replace alumina in the air abrasion system. These bioactive glasses were hard enough to cut cavities in teeth and were also able to form apatite in vitro. Dental researchers can utilize the knowledge from this book to replace alumina in the air abrasion system by the bioactive glasses which are more useful and dental...
