Brief Summary:
This clinical study identified the Candida species from the palate and complete dentures of edentulous individuals with prostheses-related stomatitis (PRS) and evaluated the effect of disinfectant solutions for denture hygiene on Candida spp. Sixty participants were randomly assigned in 04 parallel groups (n = 15); They were oriented to brush their prostheses and the palate 3 times a day and immerse them in saline solution (C-control), 0.25% Sodium hypochlorite (HS0.25%), 10% Ricinus communis (RC10%) or 0.5% Chloramine T (CT 0.5%) for 20 minutes. Biofilm samples were collected from the prostheses and palate in the baseline, after 7 and 37 days of use of the solutions and seeded in CHROMagar Candida medium. After incubation period, the presumptive identification, incidence verification and quantification of Candida species growth (CFU count) were performed. To quantify biofilm with software ImageTool 3.0, the inner surface was disclosed (1% neutral red) and photographed at the end of each period. The Candidiasis remission was assessed by scores before and after the use of solutions by palate's phographs. Descriptive analyzes were used for the identification and incidence of Candida spp. Kruskal-Wallis and Friedman tests, with stepwise step-down post-test for cell growth; ANOVA and Tukey for biofilm removal; Frequency of scores for evolution of inflammation. Level of significance was 95%. The most incident species were C. albicans, followed by C. tropicalis, C. glabrata and C. krusei. HS 0.25% reduced the incidence of the three species on the prostheses and palate in the periods of 7 and 37 days; CT 0.5% promoted reduction of Candida spp. only in dentures. R. communis decreased the incidence of C. tropicalis in both collection sites. For CFU counts, HS 0.25% and CT 0.5% caused significant reduction. For biofilm removal, HS0.25% was the most effective (9.75 ± 12.6) and RC10% (15.92 ± 14.8) intermediate. All groups decreased protheses-related stomatitis. HS0.25% has potential for clinical use as total denture disinfectants. RC10% and CT0.5% require further studies to be indicated as alternative solutions.
