INTRODUCTION: There has been an increased interest in the influence of denture adhesives on Candida albicans growth in denture wearers. AIMS AND OBJECTIVES: To compare the mean colony count and pH of Candida cultures grown in the presence of acrylic resin plates treated with two forms of a denture adhesive. DESIGN: A quasi-experimental design. METHODS: Two of three groups of 30 acrylic resin specimens were treated separately with two forms of a denture adhesive. The remaining group was left untreated. Ten specimens from each group were incubated for 6 hours, 24 hours and 48 hours following the addition of a diluted strain of Candida albicans. The number of colonies and pH of the culture media were recorded over three measurement occasions and analysed. RESULTS: Plates from the two forms of a denture adhesive had no colonies in the countable range in contrast to plates from the control group. The study found significant mean differences in pH values over three measurement occasions as well as significant group differences in terms of how the means vary over time. However, the results showed a significant time x treatment group interaction. CONCLUSIONS: Both forms of the denture adhesive tested inhibited the growth of candida.
