摘要： A dental treating apparatus according to the present invention includes: a hand piece (1); a head unit (2); a driving unit (13); a resistor (13d) for load detection; a load comparing unit (110); and a control unit (11). The hand piece (1) drivably holds a cutting tool (5) on the head unit (2). The driving unit (13) drives the cutting tool (5) in a normal rotation direction or in a reverse rotation direction. The resistor (13d) for load detection detects a load applied to the cutting tool (5). The load comparing unit (110) compares the detected load and a reference load each time driving for rotating the cutting tool (5) in the reverse rotation direction by a predetermined rotation angle is performed. The control unit (11) controls the driving unit (13) based on a result of comparison by the load comparing unit (110).

摘要： A dental treating apparatus according to the present invention includes: a hand piece (1); a head unit (2); a driving unit (13); a control unit (11); a load specifying unit (13d); and a load comparing unit (110). The hand piece (1) drivably holds a cutting tool (5) on the head unit (2). The driving unit (13) drives the cutting tool (5) in a normal rotation direction or in a reverse rotation direction. The load comparing unit (110) compares a load detected by the load specifying unit (13d) and a reference load. During a normal rotation period until driving for rotating the cutting tool (5) in the normal rotation direction by the driving unit (13) satisfies a predetermined first condition, the control unit (11) maintains a rotation direction of the cutting tool (5) in the normal rotation direction, and when a result of comparison by the load comparing unit (110) attains a predetermined result during the normal rotation period, the control unit (11) controls the rotation direction of the cutting tool (5) to the reverse rotation direction.
