  • Patent number: 12329438
    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.

  • Publication number: 20230173268
    Abstract: A treatment device that shortens the time period until healing is determined even when a bone defect or a root apex lesion is generated in an apical area. The treatment device includes a file holder, a high-frequency signal generating circuit, and a control circuit. The file holder holds a file to be located in the site to be treated. The high-frequency signal generating circuit passes a high frequency current through the file. The control circuit controls a frequency of the high frequency current to be passed through the file from the high-frequency signal generating circuit. The control circuit controls the frequency of the high frequency current to be passed through the file within a range of 1.001 MHz to 11.700 MHz.
