Assessing the cutting efficiency of dental diamond burs

Article Abstract:

There appear to be little or no differences between the cutting abilities of disposable diamond burs compared with conventional sterilizable burs. Researchers used a laboratory simulation to evaluate 10 samples of 16 types of burs from 9 manufacturers. Twelve of the burs were disposable. Using a standard handpiece, ten consecutive grooves were cut with each bur in a piece of glass ceramic surface. The surface was weighed after each cut to measure how much material was removed. Three of the four conventional burs removed less material in cuts 6 through 10 compared with cuts one through five due to clogging. The same was true for 8 of 12 of the disposable burs. Medium-grit disposable burs had similar cutting efficiencies to medium-grit conventional burs.

Dental cutting: the historical development of diamond burs

Article Abstract:

The diamond dental bur was first manufactured in 1897 but its modern incarnation did not appear until 1932. At that time, a German industrialist developed a method for bonding small diamond pieces onto stainless steel. The bur did not become widely accepted until the introduction of the high-speed drill in 1957. The diamond chips are bonded to a stainless steel tip that is inserted into the drill. Diamond burs are allegedly more resistant to wear and last longer. The burs must be thoroughly cleaned and sterilized between use and a disposable bur has been developed.

Enhanced dental cutting through chemomechanical effects

Article Abstract:

Adding small amounts of mouthwash to the water coolant spray in a dental drill can increase the cutting rate two or three times. The mouthwash reduces surface tension, and can improve cutting rates using both carbide and diamond burs.
