Abstract : [ABSTRACT] We assessed the efficacy of disinfection using free radicals. The effects of different disinfection methods on poly (methyl methacrylate) (PMMA) were also investigated. PMMA was either untreated, or was disinfected with 70% alcohol, 5% sodium hypochlorite, or free-radical producing matter. The degradation of the surface of PMMA after disinfection with sodium hypochlorite was similar to that observed for the untreated surface. Thus, the use of free radicals did not change the surface roughness. Furthermore, the strength of each tested material showed trends similar to those observed for surface roughness. These findings suggest that free radicals may be used for disinfection in future. In addition, free radicals do not harm the environment because they are chemical-free.
