QUALITY CONTROL OF A METALLIC DENTAL BUR WITH A DIAMOND COATING

During operation, sterilization and disinfection, the surface working part of dental burs deteriorates. In this study a commercial metallic dental bur with extra coarse gradation (177-250 µ of ceramic em-bankment), made of a stainless steel were covered with a nickel-diamond composite was examined. The working part of the tool is round-end taper shaped and is intended for crown and bridge prepara-tion. Analysis of microstructure was carried out using Jeol JSM-6610 LV scanning electron micro-scope with EDX analyzer. After 3 months of operation, the bur can be used for further work in the dental surgery.
