Abstract

The objective of this study was to determine the cutting power of diamond burs obtained by the HFCVD deposition process. Diamond was deposited on the active part of each of a series of 10 commonly used Tungsten Carbide (WC) commercial burs. The quality of the section was compared with sections made by commonly used commercial burs, employing fresh human molars and a standard device [1]. Both burs and sections were analysed by using SEM and EDX techniques. The quality and tension of the deposited diamond coatings were analyzed by Raman Spectroscopy. The optimal thickness of the diamond coating which provided the best durability and finish of the sections was determined by comparative observations of results.
