Variations in the design of #330 dental burs.
This evaluation consisted of a photographic evaluation of eight brands of commercially available #330 burs; comparisons were made to the standard as set by Dr Miles Markley. They were also evaluated as to their meeting ADA Specification No 23 for dental burs. In a second portion of the study, the burs were used to prepare channels in extracted teeth, and the pattern produced was evaluated. The results indicate that there is a great difference in the shape of the burs produced by the various manufacturers, as there was in the pattern they produced in preparing tooth structure.
