Objectives To evaluate the effect of sodium hypochlorite ( N a OC l) on biofilms, colour stability (Δ E ) and surface roughness ( R a) of complete dentures and patient acceptability. Background Denture cleansers should be able to reduce the accumulation of biofilms without affecting the acrylic resin properties. Patient satisfaction is important to maintaining their daily use. Materials and methods Fifteen participants were instructed to keep their dentures immersed daily in a 0.5% N a OC l solution for 3 min over 90 days. Swabs were taken from dentures and inoculated on CHROM agar and blood agar. The number of colony‐forming units (cfu) was counted after a 48‐h incubation period. Δ E was assessed using the CIE L *a*b* system. Ra was measured using a profilometer. Patient acceptability was checked based on their degree of satisfaction. Cell counts, Δ E and R a were analysed using anova , F riedman's and K ruskal– W allis tests, respectively (α = 0.05). Results A significant reduction in the total number of microorganisms ( p = 0.001) and C andida spp. was noticed. No significant differences were found for Δ E ( p = 0.68) and for R a ( p = 0.47). The level of the patient satisfaction increased throughout the follow‐up period. Conclusion The 0.5% N a OC l solution was effective in reducing microorganisms without significant changes in colour or roughness of denture resin. The participants reported satisfaction with the cleaning results.
