Abstract
A dental treatment apparatus includes a holder, a power supply, root canal length measurement circuitry, and control circuitry. The holder holds an electrode placed in a root canal. The power supply energizes file with a high-frequency current. The root canal length measurement circuitry electrically measures a position of a distal end of electrode in the root canal. The control circuitry causes, in accordance with information on the position of the distal end of the electrode measured by root canal length measurement circuitry, the power supply to control a current value of the high-frequency current which energizes the electrode.
