I am in total agreement with Dr. Weisman’s comments. While I did not elaborate on the subject in my article, I feel strongly about the potential for damage to both vital and nonvital teeth when cutting with high-speed handpieces. The potential for damage is related not only to the concentricity of the hand-piece and bur, but also to the generation of heat and drying of tooth structure.

Cutting tooth structure with high revolutions per minute without adequate water spray produces tremendous potential for fracture, both from vibration and drying. Even when the greatest care is taken to avoid such damage, we need to examine teeth, both vital and nonvital, after cutting with high speed to determine whether any iatrogenic fracture has occurred. Dr. Weisman’s comments are well-taken.
