FotoSan® treatment is an antimicrobial treatment usinge red light (630 nm) and a photosensitizer called toluidine blue (TBO). Briefly what happens is tha the red light activates the TBO killing bacteria with no side effects on human cells.
I have used FlashMax since it was introduced to the market in 2007. It is strong and efficient and I do not have to sit and wait and wait. The composites are well cured deeper and harder compared to all the other lights we have in the office.
