The plasma endodontic treatment device treats infected tooth pulp, easing pain and swelling by removing damaged tissue and filling the space. It creates plasma discharge between two separate electrodes, using tiny currents to clear inflamed material, disinfect, and stop bleeding in the root canal. The device manages power well by changing the gap and voltage of electrodes to avoid excess current. It also has an LED display that shows energy strength through colors, letting users easily check and set the power level.
