.....Well I don't have to wait '3 years' for this kind of treatment. Matter of fact, anyone can cheaply do it in their own home now. I just ordered a Streamlight Stylus Pen Light in both red and blue LED light from Amazon. This will be used in combination with peroxide irrigation. A scientific article on the web, shows that this method WORKS:
An antibacterial synergic effect between blue light and H2O2 was observed. The mechanism of the phototoxic effect on S. mutans was basically a photochemical process, in which ROS were involved. Application of such light in combination with H2O2 to an infected tooth could be an alternative to or serve as an additional minimally invasive antibacterial treatment.
