    摘要： The present invention has an object of providing a root canal treating display device, a root canal treating unit, and a dental image display method that minimize a healthy area of a tooth to be cut and guide a cutting tool to a desired root canal R in a root canal treatment. A root canal treating display device includes a three-dimensional information storage unit 15a that stores three-dimensional information including information on a root canal R of teeth, the three-dimensional information being acquired by an X-ray CT image capturing device 60; a target tooth specification operation unit 12a that specifies the tooth as a target of interest; a tooth image processing unit 11a that creates a tooth image I of the tooth; a monitor 13 that displays the tooth image I; and a root canal extension direction processing unit 11b that creates a root canal extension direction image Id showing a root canal extension direction along the root canal R of the tooth based on the three-dimensional information, and displays the root canal extension direction image Id on the monitor 13 as overlapping, and in correspondence with, the tooth image I.

    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).
