Abstract :
Using the plasma generated inside the root canal rather than the afterglow of the plasma will significantly improve the inactivation efficiency. In this paper, images of three kinds of atmospheric-pressure low-temperature plasma devices driven by different power supplies in the tooth root canal are reported. The images of an R-needle device driven by a dc power supply inside the root canal using different gases (He, Ar, and surrounding air) are also presented.
