Abstract:
Abstract Introduction: Cross-contamination between dental office and prosthetic laboratories is of utmost importance. The dental prosthesis could harbor tones of microorganisms harmful to health staff. It has been estimated that more than ۶۰% of the prostheses delivered to clinics from laboratories or vice versa are contaminated with pathogenic microorganisms. Several disinfection methods and chemicals have been proposed for sanitizing prostheses. Cold plasma, or nonthermal plasma, has been introduced as a new method in medical equipment disinfection. The current study aimed to compare the antimicrobial effect of cold plasma and the routinely used alcohol-based impression disinfectant ASEPTOPRINT® on disinfecting dentures.Methods: In this experimental study, ۳۰ maxillary complete dentures were used as the microbial source. Dentures were randomly divided into ۳ groups: (۱) cold plasma treatment for ۳۰ seconds, (۲) cold plasma for ۶۰ seconds, (۳) ASEPTOPRINT® spray. Microbial culturing was taken before and after disinfection in each group on both Blood Agar plates and Soborou Dextrose Agar (SDA) plates. After ۴۸ hours incubation at ۳۷°C, the number of colonies was counted using a digital colony counter and differences between the groups were analyzed.Results: A significant reduction in microbial colonies was observed after using all disinfection methods. ASEPTOPRINT® spray showed more antimicrobial effects comparing to cold plasma.Conclusion: The antimicrobial effect of ASEPTOPRINT® spray solution is more than cold plasma application on both microbial and fungal microorganisms. The time of plasma application was not accompanied by any significant differences in the results. Keywords: Acrylic dentures Disinfection Cold plasma ASEPTOPRINT® spray
