This review of effect of microwave disinfection on the dimensional stability of denture base acrylic resins included 7 in-vitro studies. A wide range of microwave disinfection protocols were used with the reviewers specifying two protocols that may be safe. However because of the heterogeneity and the small number of studies included these finding should be considered cautiously.

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…]
