Abstract
A dental treatment apparatus is a dental treatment apparatus that energizes a dental treatment site such as a root canal with a high-frequency current. Included are a holder that holds an electrode placed at the dental treatment site, a power supply that energizes the electrode with the high-frequency current, and control circuitry that causes, during the energization operation, the power supply to provide stop period where the energization of the electrode with the high-frequency current is stopped between single energization period and next single energization period.
Claims14
A dental treatment apparatus that energizes a dental treatment site with a high-frequency current, the dental treatment apparatus comprising:
- a holder configured to hold an electrode placed at the dental treatment site;
- a power supply configured to energize the electrode with the high-frequency current;
- and
- controller circuitry configured to:
- cause, during energization operation, the power supply to provide a stop period where energization of the electrode with the high-frequency current is stopped between a single energization period and a next single energization period, and
- cause the power supply to provide a plurality of continuous energization periods in the single energization period and to interpose a pause period where the energization of the electrode with the high-frequency current is paused between two adjacent continuous energization periods,
- wherein the pause period is shorter than the continuous energization period, and the stop period is more than twice the continuous energization period.
