An abnormality determination device for a dental handpiece, the abnormality determination device including: an electrical current output unit configured to supply, to a drive motor attached to the dental handpiece, a test electrical current in a no-load state, the test electrical current being smaller than a no-load electrical current at a rotational speed of the dental handpiece during a normal treatment in the no-load state; a rotational speed detector configured to detect a rotational speed of the drive motor in a state where the test electrical current is supplied; a processor configured to compare the rotational speed detected by the rotational speed detector with a threshold rotational speed; and an abnormality detector configured to determine abnormality that the dental handpiece is abnormal if the rotational speed detected by the rotational speed detector is smaller than the threshold rotational speed.
An abnormality determination device for a dental handpiece, the abnormality determination device comprising:
An abnormality determination method for a dental handpiece, the method comprising:
A non-transitory computer-readable storage medium storing a program executable by a computer of an abnormality determination device for a dental handpiece, the program, when executed by the computer, causing the abnormality determination device to perform:
