“…It has been reported that dental prostheses are often contaminated with microorganisms and can serve as the primary source in the cycle of cross infection within dental laboratories. The polishing of dentures without previous disinfection can lead to a high level of transfer of microorganisms to dental personnel, polishing instruments, and the new dentures …”

“…The polishing of dentures without previous disinfection can lead to a high level of transfer of microorganisms to dental personnel, polishing instruments, and the new dentures. 35,36 With populations living longer, health management and disease prevention become increasingly important. Since the impact of oral status on systemic health is well established, better understanding of dental treatment effects on oral microflora and bacterial colonization should be a major concern of modern dentistry.…”

The biocompatibility, relatively low cost and excellent aesthetic appearance of polymer Poly(methyl methacrylate) (PMMA) makes it the material of choice for fabricating partially and complete dentures. Nowadays the emerging 3D printing technique imposed itself as reliable solution for obtaining dental devices. However, extensive usage of such technique is still limited due to the materials available. Despite PMMA's drawbacks, mainly related to bacterial contamination, wear and mechanical failures, composite polymeric matrix has issued high interest lately. An important improvement in basic material properties have been achieved due to the inclusion of nanosystems, either nanoparticles or nanotubes. The newly shown versatility of reinforced PMMA sustains it as the best alternative for stereolithography (3D printing) technique. This paper highlights the improvements of PMMA by adding different type of nanofillers. Therefore, prospective randomized clinical in vivo studies with the use of biocompatible tested modified filled PMMA and modern technologies should be performed.

“…The potential risk of contamination with the aerosols and pathogens exists during all dental procedures encompassing trimming, finishing, and polishing, so there is a need for appropriate disinfection techniques which act efficiently on a broad spectrum of microorganisms and are cost-effective, rapid and safe for human's health. [2][3][4][5] The disinfection of the dental impressions is strongly recommended by the health policymakers such as the Centre for Disease Control (CDC), the American Dental Association (ADA) and the British Dental Association (BDA) to prevent the possible transmission of infectious diseases and cross-contamination. [6][7][8] Although guidelines for sterilization and disinfection have been established by these organizations, investigations have shown that proper practice is not always followed.…”

Antimicrobial Activity of Cold Plasma Treatment on Acrylic Denture Bases: An In Vitro Evaluation

et al. 2019

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 60% 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, 30 maxillary complete dentures were used as the microbial source. Dentures were randomly divided into 3 groups: (1) cold plasma treatment for 30 seconds, (2) cold plasma for 60 seconds, (3) 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 48 hours incubation at 37°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.
