The present Invention Patent refers to the caries removal procedure through the cavity preparation with rotary equipment of ultra-low rotation, increasing significantly the work precision, specially on the micro-mechanical approach of the treated tissue, showing many advantages over the traditional micro-mechanics, between them: it is extremely less traumatic, with selective tissue protection, much lower pulp exposure risk and/or crack formation during the mechanical preparation, lack of contaminated spray in the working place and much lower possibility of patients feel pain or stress during the procedure, since there is practically no irritant noise, vibration and no needing to use anesthetics in most cases, all this due to the extremely low speed applied, focusing the use of the Ultra-Low Rotation on the deteriorated dentin tissue (with lower micro-mechanics resistance and low sensitivity) that normally is found very infected mostly by obligate anaerobic bacteria.
