Adequate denture hygiene is important to patient's oral health maintenance in particular because of Candida albicans, responsible for the development of denture stomatitis. The aim of this study is to conduct a randomized controlled trial seeking for the best hygiene protocols to be used in removable denture wearers. The null hypothesis tested is that there will be no difference among the denture hygiene protocols tested.

| Amount of biofilm formed on the denture | Biofilm will be measured on the denture using photographs and microbial counts (baseline and after 14 days of use of one of the four hygiene protocols) after using one of the tested denture hygiene protocols. The four tested protocols (NaOCl, chlorhexidine, sodium bicarbonate, water) will be compared to see which one leads to a better hygiene of the denture. | 14 days |
