Abstract

 The aim of the present study was to evaluate the efficiency of Photodynamic method as a disinfection procedure to the Prosthetic Dentistry. The conventional cleansing procedures were applied in comparison. Second generation photosensitizers from the group of phthalocyanines were synthesized and applied for photodynamic studies of inactivation of pathogenic microorganisms associated with dental impressions. The results showed that Photodynamic disinfection (PDD) can be successfully applied for the samples of dental impressions contaminated experimentally and especially the samples of humans origins. PDD as a new procedure was more efficient and competitive to the conventional disinfections of impressions.
