Only limited evidence on the use of photodynamic therapy in root canal disinfection


Photodynamic therapy (PDT) has been suggested as a potential adjunctive aid to disinfection of the root canal. In principle, it uses a nontoxic photosensitizer that is selectively absorbed in a target tissue and a low-intensity light source. Upon photo-induced activation of the photosensitizer, in the presence of oxygen, a series of reactions produce free radicals [read the full story…]
