Abstract: A root canal treatment instrument 100 continues drive of a cutting tool 5 in forward rotation drive until reaching 180 degrees, and when a load applied to the cutting tool 5 is equal to or greater than a reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 90 degrees. In the root canal treatment instrument 100, when a cumulative amount of rotation is equal to or greater than a reference amount of rotation, change to a drive pattern is made, forward rotation drive is continued until reaching 90 degrees, and when a load applied to the cutting tool 5 is equal to or greater than the reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 180 degrees.

Abstract: The A root canal treatment apparatus includes: a handpiece configured to hold a cutting tool in a head in a drivable manner; a motor driver and a micromotor configured to drive the cutting tool; a root canal length measurement circuit; and a control portion. The root canal length measurement circuit is configured to electrically detect a position of a tip end of the cutting tool in a root canal, using the cutting tool as a measuring electrode. The control portion is configured to perform drive for reversely rotating the cutting tool by a predetermined set angle (180 degrees) when the position of the tip end of the cutting tool detected by the root canal length measurement circuit reaches a predetermined set position, and then, stopping rotation.

Abstract: A dental treatment apparatus includes: a handpiece including a head that holds a cutting tool; a drive unit capable of performing forward rotation driving for rotating the cutting tool held at the head in a cutting direction, and reverse rotation driving for rotating the cutting tool held at the head in a non-cutting direction; an operation receiving unit that receives an operation of an operator; and a controller that controls the drive unit that drives the cutting tool, according to the operation received by the operation receiving unit. Only when a prescribed condition is satisfied, the controller sets the operation received by the operation receiving unit as an operation to drive the cutting tool by reverse rotation driving, or as an operation to drive the cutting tool by twist driving by which the forward rotation driving and the reverse rotation driving are alternately performed.
