This research work is presented as a quantitative analysis of wear generated on spherical diamond dental burs. To reproduce the clinical conditions in the most precise manner, a laboratory experiment was designed, in which burs from two different manufacturers were compared, each of them being used during 30-minute intervals in cavity preparations on extracted dental pieces. The change in mass and in the outer profile of each bur was quantified. In addition, by means of microscopic analysis, the different wear mechanisms involved during the use of the burs were observed and described. Finally, a comparison was made between the burs’ wear rate and unit price.
