Effect of Different Disinfecting Agents on Dental Impressions Contaminated with Candida albicans

Introduction: This research was carried out to compare the effects of 0.525% and 5.25% NaOCl, 2% H2O2, and 16-mg/mL propolis on additional silicone impression materials contaminated with Candida albicans at 5- and 10-minute exposure times, to evaluate the hypotheses of this study that propolis can b...

Materials and methods: A total of 122 silicone impressions were prepared. Two samples were considered the negative controls, and the rest were contaminated with C. albicans fungal species and disinfected with 0.525% NaOCl, 5.25% NaOCl, 2% H2O2, 16-mg/mL propolis, and 96% ethyl alcohol for 5 and 10 minutes (10 samples for each interval in each group). The data were analyzed with Kruskal–Wallis and Mann–Whitney U tests in all the groups at 5- and 10-minute intervals. Results: All the disinfecting agents significantly decreased C. albicans colony counts at both intervals compared to the control groups (P = 0.00). The differences in the disinfecting effects were significant between the four study groups (P = 0.00). The most significant effects were related to NaOCl at both intervals and concentrations and 2% H2O2 at the 10-minute interval (P = 0.001), followed by 2% H2O2 at the 5-minute interval and propolis (P = 0.001). Concerning propolis (P = 0.001) and 2% H2O2 (P = 0.004), the effect of exposure time was significant. Conclusion: All the disinfecting agents in the present study can be used to disinfect impressions contaminated with C. albicans; however, concerning propolis, although it resulted in significant decreases in C. albicans colony counts, the elimination of the remaining colonies was ineffective.Masoumeh AslanimehrFatemeh GholamiSiavash TorbatiShima AalaeiWolters Kluwer Medknow Publicationsarticle candida albicans disinfectionhydrogen peroxidepropolissodium hypochloriteDentistryRK1-715ENDental Hypotheses, Vol 12, Iss 3, Pp 139-143 (2021)
