DEVELOPMENT OF METHODS FOR EVALUATION OF ROTATING DENTAL DIAMOND ABRASIVE INSTRUMENTS

摘要

A continuing program of research on the cutting characteristics of rotating dental instruments has been conducted at the Dental Research Laboratory of the National Bureau of Standards. This project has included studies of the cutting effectiveness of diamond instruments. There has been a widespread tendency toward the increased use of these instruments as a result of the higher handpiece rotational speeds now available to the dental profession. Recent work (1, 2) has indicated that diamond abrasive instruments operate more efficiently than steel or carbide burs in the removal of tooth enamel. Ingraham's work (3) provides a more efficient method for the rapid removal of hard tooth structures by means of modern instrumentation.
