Photodynamic Disinfection of Dentures

چکیده
Photodynamic disinfection is a new method for cleaning dentures of edentulous patients. It is based on the photochemical action of a photoactive dye (photosensitizer), activated by proper light in the presence of oxygen. The mechanism of photosensitization directs the generation of reactive oxygen species that destroy the pathogens. A pilot study of photodynamic disinfection of dentures was carried out. Four different photosensitizers susceptible to red light were used for the investigation. Results showed that photodynamic disinfection is an effective method for inactivation of pathogens on dentures as a part of prevention of cross-contamination in dental office. It also can be used as a part of the therapy of denture stomatitis.

INTRODUCTION Photodynamic therapy is a topical treatment of pathogens that involves the use of a photoactive dye (photosensitizer), which is non-toxic when not exposed to light and activated by light of a specific wavelength in the presence of oxygen. The highly cytotoxic oxygen species generated by the induced photophysical processes inactivate the pathogenic cells. The PURPOSE of this study w...

متن کاملEvaluation of Photodynamic Therapy with 660 nm Diode Laser and Different Concentrations of Methylene Blue on Candida Albicans growth on Denture(laboratory study)
Background and Aim: Candida has an important role in denture-dependent stomatitis. The use of lasers and light-absorbing materials to act against this fungus has been suggested in some studies. In this study, the antifungal effects of 660 nm diode laser with different concentrations of methylene blue as a light absorbing agent against Candida albicans grown on dentures was investigated. Materia...

Commonly used irrigants do not always eradicate the entire microbial flora in infected root canals. Therefore, several other strategies, such as photodynamic therapy (PDT) have been developed. Photoactivated disinfection is based on the interaction of a photosensitive antibacterial agent and a light source. It uses a nontoxic dye named photosensitizer (PS) and low-intensity visible light. In ox...
