“…The most commonly used chemical solution is NaClO, however it can cause deleterious effects to the denture when used at 1% or 0.5% concentrations 4 , 17 , 19 , 20 . Therefore, the assessment of NaClO at lower concentrations, as well as of new chemicals, is needed to help clinicians and patients find more suitable solutions.…”

“…However, it is still necessary to evaluate the adverse effects of 0.25% NaClO and 10% R. communis (S3) on the acrylic resin of the denture. In the literature, only one study evaluated the surface roughness with the same solutions, which demonstrated clinically acceptable values, once they were below of 0.2 μm 4 .…”

“…However, these solutions may adversely affect physical and mechanical properties of the denture 4 , 17 . In addition, the unpleasant taste and odor of NaClO may cause some discomfort for patients, although there aren’t studies that have evaluated the extent of this problem.…”

The development of opportunistic infections due to poor denture hygiene conditions justified the search for effective hygiene protocols for controlling denture biofilm. Objective This study evaluated Ricinus communis and sodium hypochlorite solutions in terms of biofilm removal ability, remission of candidiasis, antimicrobial activity, and participant satisfaction.Material and Methods It was conducted a controlled clinical trial, randomized, double-blind, and crossover. Sixty-four denture wearers with (n=24) and without candidiasis (n=40) were instructed to brush (3 times/day) and immerse their dentures (20 min/day) in different storage solutions (S1 / S2: 0.25% / 0.5% sodium hypochlorite; S3: 10% R. communis; S4: Saline).The trial period for each solution was seven days and a washout period of seven days was used before starting the use of another solution. The variables were analyzed at baseline and after each trial period. The biofilm of inner surfaces of maxillary dentures was disclosed, photographed, and total and dyed areas were measured (Image Tool software). The percentage of biofilm was calculated. Remission of candidiasis was assessed by visual scale and score were attributed. Antimicrobial activity was assessed by the DNA-Checkerboard hybridization method. Patient satisfaction was measured using a questionnaire.Results S1 (4.41±7.98%) and S2 (2.93±5.23%) were more effective then S3 (6.95±10.93%) in biofilm remotion(P<0.0001). All solutions were different from the control (11.07±11.99%). S3 was the most effective solution in remission of candidiasis (50%), followed by S1 (46%). Concerning antimicrobial action, S1/S2 were similar and resulted in the lowest microorganism mean count (P=0.04), followed by S3. No significant differences were found with patient’s satisfaction.Conclusions 10% R. communis and 0.25% sodium hypochlorite were effective in biofilm removal, causing remission of candidiasis and reducing the formation of microbial colonies in denture surfaces. All solutions were approved by patients.

“…However, the useful life of these materials is compromised as a result of changes in physical integrity, surface detail, color, and fungal colonization . These changes can be intensified by the use of hygiene methods, which are essential for denture users, because they promote biofilm removal, assist in the control of oral diseases, and help maintain oral health.…”
