SummaryBackground/Aim: Although there are studies about the antimicrobial activity of silver, there is no study evaluating it as a denture disinfectant. The purpose of this study was to explore the effectiveness of 6 disinfectant solutions (50% vinegar, 100% vinegar, 1% silver nitrate, 2% silver nitrate, %1 sodium hypochlorite, 0,12% chlorhexidine digluconate) in the disinfection of acrylic resin specimens contaminated in vitro by Candida albicans, as measured by residual colony-forming unit (CFU).Material and Methods: 66 pieces of 10mmx2mm acrylic resin disc samples were prepared and incubated in 1x106 cell/ml suspension of C. albicans ATCC 18804 for 24 h (one of them as a control, n=11/group). The specimens were then transferred into tubes containing 10 ml of the tested disinfectants and kept for 10 minutes in the disinfectant. After washing with saline, the specimens were vortexed to remove the microorganisms adhered to the surfaces. Colony counting of the collected microorganisms was performed on Sabouroud dextrose medium using 10−1, 10−2 and 10−3 dilutions. The results were analysed using Kruskal-Wallis and Mann-Whitney U tests (p<0,05).Results: The results showed that 1% sodium hypochlorite, %1 silver nitrate and 2% silver nitrate were the most effective against Candida Albicans (p<0,05), followed by 100% vinegar, 0,12% chlorhexidine digluconate and 50% vinegar (p<0,05).Conclusions: Within the boundaries of this study, we conclude that 1% silver nitrate is a promising alternative disinfectant to 1% sodium hypochlorite and performs better compared to 0,12 % chlorhexidine gluconate, 50% and 100% vinegar.

BACKGROUND Sodium hypochlorite & chlorhexidine are usually employed as endodontic irrigants due to their antimicrobial properties, however, their cytotoxicity & allergenicity issues demand an equally effective but safer irrigant. The purpose of the study was to compare the antimicrobial efficacy of octenidine hydrochloride (OCT), green tea, sodium hypochlorite and chlorhexidine (CHX) at various concentrations against E. faecalis, C. albicans and its mixture. METHODS The study was conducted in Hitkarini Dental College, Jabalpur. Various concentrations of irrigants were prepared. Muller Hinton agar media plates were swabbed with the culture broth of E faecalis ATCC 29212, Candida albicans ATCC 10231 or a mixture of these. Five Whatman paper disks (6 mm), each loaded with experimental concentration of the irrigant, were placed at equal distance on to the plate. The plates were incubated at 370 C for 48 hours. This was done in 6 replicates. The plates were evaluated for clear zone of inhibition measured in mm. RESULTS The diameter readings were analysed using Kruskal Wallis and Mann Whitney U tests. There was a significant difference between the groups against Enterococcus faecalis; candida, & mixed culture (P < 0.01). CONCLUSIONS 5 % Sodium hypochlorite is better than all others whereas 2 % CHX is better than OCT & Green tea. 0.1 % OCT is better than 3 % Green tea. OCT can be used as a contributory irrigant along with NaOCl to achieve antimicrobial advantage.

Antifungal Efficacy

Widely used materials are reported as denture cleansers are peroxide and hypochlorite. Many contradictions on the effectiveness of the commercial peroxide base solution against Candida albicans (C. albicans). Low concentration sodium hypochlorite (0.5%) is used as a household sanitizer. But it is still unknown whether it has an antifungal effect, what is the optimum concentration and contact time to destroy the yeast. The purpose of this study is to examine the antifungal efficacy of commercial peroxide-based soaking solution and low concentration sodium hypochlorite against C. albicans, to determine the optimum concentration and contact time, and at the end, to obtain an effective denture soaking solution which is safe to use, easy to get, affordable and could be used to destroy C. albicans on dentures. The research conducted was an in vitro practical test for surface disinfectant. Sixty plates of acrylic which were already incubated with C. albicans are immersed in peroxide and hypochlorite base soaking solution in different concentration and contact time. The result showed that peroxide base was not effective to C. albicans and hypochlorite base solution can destroy C. albicans in 10 minutes at a concentration of 0,125%. Thus, the use of low concentration sodium hypochlorite as a denture soaking solution can be suggested.
