Abstract: A dental treatment apparatus includes a holder, a high-frequency signal generation circuit, a detector, and a control circuit. The holder holds an electrode placed at a dental treatment site. A power supply energizes the electrode with a high-frequency current. A detector detects a current value which energizes the electrode. A control circuit causes, based on the current value detected by detector, the power supply to control a current value of the high-frequency current which energizes the electrode.

Abstract: In a medical system, a medical device includes a first display that displays a figure or a character corresponding to data relevant to medical treatment performed in the medical device, and a first controller that causes the first display to display the figure or the character corresponding to the data and that, when the data satisfies conditions for notification of a warning, causes the medical device to emit a first warning. A remote control device includes a second display that displays the figure or the character corresponding to the data, and a second controller that causes the second display to display the figure or the character corresponding to the data and that, when the data satisfies the conditions for notification of the warning, causes the remote control device to emit a second warning that is different than the first warning.

Abstract: A dental treatment apparatus includes a holder, a power supply, root canal length measurement circuitry, and control circuitry. The holder holds an electrode placed in a root canal. The power supply energizes file with a high-frequency current. The root canal length measurement circuitry electrically measures a position of a distal end of electrode in the root canal. The control circuitry causes, in accordance with information on the position of the distal end of the electrode measured by root canal length measurement circuitry, the power supply to control a current value of the high-frequency current which energizes the electrode.
