Plasma Bleaching 'Having a Whiter Future'

Tooth bleaching has become a popular aesthetic service in dentistry. Hydrogen peroxide is a widely used bleaching material that is effective and safe. In office systems use 30%-40% H202 and a high intensity light source. Application of light source might enhance bleaching by heating the H202 but has some potential complications.Plasma is the fourth state of matter also known as "Ionized Gas" and has potential biomedical applications because it is non thermal and nontoxic and can be realized in simple hand-held device. Room temperature plasma can be used for tooth bleaching with much better results and has an edge over the potential complications with the conventional in office techniques. Thus a combination of plasma treatment and H202 gels are being considered as an effective method of tooth bleaching.This poster presents plasma bleaching as the recent bleaching technique with better results on the safer side.
