Valutazione della capacità di taglio di tre punte diamantate a diversa granulometria nella preparazione protesica di elementi dentari

This in vitro trial has produced results that disagree with the data obtained by the few previous studies of comparable methodological approach and interest topic. Indeed, in the literature some trials demonstrate no relationship between diamond grain size and cutting ability of rotating instruments. Other studies show a reduced grinding power expressed by the medium grain size diamond points compared to coarser abrasive burs, especially during prolonged or repeated use. The studies disagreement in this field should stimulate further trials preferably by means of clinical rather than in vitro procedures.
