Background: Although there are a diversity of methods proposed for cleaning complete dentures, there is still no consensus in the literature about which method is most effective for removing biofilm from acrylic resin denture base surfaces. Although chlorhexidine is mostly used, benzoic acid has emerged as an effective method of denture cleansing. This study aimed to examine the efficacy of denture soaks by benzoic acid against the colonization of Candida albicans compared to zordyl (chlorhexidine gluconate 0.2%). Materials and Methods: This is a randomized controlled trial conducted in Al-Azhar University, Assiut Branch, Faculty of Dentistry, in Egypt during a 4-month period. One hundred edentulous patients with complete dentures were assigned into two equal groups, group (1): Fifty patients given instructions to use benzoic acid for immersion of their dentures and they were given the prepared solution for free to be used, while group (2): Fifty patients used zordyl (chlorhexidine gluconate 0.2%) for denture immersion. The dentures were examined four times; before delivery of instructions, 1, 2, and 4 months after initial session of instructions. Results: It was found that household benzoic acid has inhibition effect against C. albicans. The differences in means of C. albicans counts between two groups were nonsignificant before the application of denture soaks, but they begin to be significant after 1 month of the application. The mean differences of C. albicans counts continue to be significant in the 2 nd and 4 th months of follow-up. Conclusion: This study showed that using benzoic acid for denture soak has an inhibition effects against the colonization of C. albicans on the surfaces of dentures more than using zordyl (chlorhexidine gluconate 0.2%).
