Abstract
The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); and a controller. The driving unit drives the cutting tool so as to be switchable between first driving in which the cutting tool is driven clockwise and second driving in which the cutting tool is driven counterclockwise. When a rotation direction in which the cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to the normal rotation is defined as reverse rotation, the controller sets the first driving as driving for the normal rotation when a first cutting tool rotated clockwise is held on the head unit, and sets the second driving as the driving for the normal rotation when a second cutting tool rotated counterclockwise is held on the head unit.
