Beschreibung
Zusammenfassung:	A dental treatment apparatus (10) includes a file holder (13), a high-frequency signal generation circuit (19), a root canal length measurement circuit (23), and a control circuit (21). File holder (13) holds a file (11) placed in a root canal. High-frequency signal generation circuit (19) energizes file (11) with a high-frequency current. Root canal length measurement circuit (23) electrically measures a position of a distal end of file (11) in the root canal. Control circuit (21) causes, in accordance with information on the position of the distal end of file (11) measured by root canal length measurement circuit (23), the high-frequency signal generation circuit (19) to control a current value of the high-frequency current with which file (11) is energized.
