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.
Claims12
A dental treatment apparatus that energizes root canals to be treated with a high-frequency current, the dental treatment apparatus comprising:
- a holder configured to hold an electrode inserted into a root canal;
- a power supply configured to energize the electrode with the high-frequency current;
- a detector configured to detect a current value flowing through the electrode which energizes the electrode;
- and
- controller circuitry configured to cause, the power supply to energize the electrode with a current having a preliminary current for the root canal, and a current value of the preliminary current being less than a minimum current value of a predetermined range and based on the current value of the preliminary current flowing through the electrode detected by the detector, the power supply is further configured to control the current to be a current value of the high-frequency current energizing the electrode to be within the predetermined range for root canal treatment or a time period where the electrode is energized with the high-frequency current having the current value within the predetermined range.
A method for controlling a dental treatment apparatus that energizes root canals to be treated including a holder that holds an electrode inserted into a root canal, a power supply that energizes the electrode with a high-frequency current, a detector that detects a current value flowing through the electrode which energizes the electrode, and controller circuitry that causes the power supply to control a current value of the high-frequency current which energizes the electrode, the method comprising:
- detecting, by the detector, a current value of a current having a preliminary current which energizes the electrode for the root canal and a current value of the preliminary current being less than a minimum current value of a predetermined range;
- and
- controlling, by the controller circuitry, based on the current value of the preliminary current flowing through the electrode detected by the detector, the current value of the high-frequency current which energizes the electrode to be within the predetermined range for root canal treatment and/or a time period where the electrode is energized with the high-frequency current having the current value within the predetermined range by controlling the power supply.
