High Frequency Treatment by New Type of Electricity Scalpel

Abstract

In the 1920s, electric scalpel was developed by W.T.Bovie. From then on it is indispensable to medical Surgery for 90 years. Now we applied new type electric scalpel to dental treatment and locate (call) it high frequency treatment. Applying the weak current, narrow point causes the highest heat by electrical resistance ; the other point diffuses electrical current. Then we can use it safely in a way that turn on high-frequency current of clotted wave pattern fitfully to teeth and gingival. I report using this Joule heat is useful to pulpectomy and root casual treatment and periodontal treatment.
