Treatment of Warts by DBD Plasma

Abstract

In the current investigation, DBD plasma was developed to treat warts caused by HPV in five patients. This plasma is non-thermal and cold plasma and does not damage tissues or temperature-sensitive materials. Its temperature after contact with the surface of warts does not exceed the surrounding surface temperature at ten degrees Celsius when fixed to it for thirty seconds, and to avoid pain, the plasma must be removed. This plasma works with alternating voltages in the form of a sinusoidal wave whose value is about 10 kV from top to top, and its frequency is 28 kHz. The five patients were treated for seven sessions; the interval between one session and another was one week. At different exposure times, it was five minutes for the first and twenty-five minutes for the fifth patient, with a time difference of five minutes. Before and after the treatment, pictures were taken with a cell phone camera to see what effect the plasma had. The treatment showed similar results, as the warts of the five patients disappeared after the seventh session. From this, we conclude that exposure time is not the main factor in treatment, as the shortest time can be adopted. Moreover, the treatment of warts with plasma is possible.
