RESUMEN
Candida species and microbial plaque on the tissue fitting surface of a maxillary complete denture and the palatal mucosa are the chief etiologic agent in the development and maintenance of denture stomatitis [Santarpia et al., 1988]. Denture stomatitis is a multifactorial condition associated with the wearing of a removable prosthesis. Predisposing factors include trauma [Bastiaan, 1976], candida infection [Budtz-Jorgensen and Bertram, 1970] [Renner et al., 1979] bacterial infection [Van Reenen, 1973] [Budtz-Jorgensen et al., 1983] and denture wearing habits [Etting, 1975] Candida albicans organism is part of the normal oral flora of healthy dentate adults [Young et al., 1951] as well as edentulous persons [Budtz-Jorgensen et al., 1975]. The change of candida albicans from commensalism to a pathogen in denture wearers is most probably due to alteration in the oral environment of the host rather than the alteration of the yeast itself [Young et al., 1951]The chief method of prevention and treatment of denture stomatitis is aimed at the : Ielimination of yeast and bacterial species from the denture tissue-fitting surface and denture supporting mucosa by means of an effective denture and oral hygiene cleansing regimen[Augsbruger and Elahi 1982] [Palenikand Miller, 1984]. However, a completely effective denture hygiene program for the treatment of denture stomatitis has not yet been developed [Santarpia et al., 1988]. This study was conducted to determine the level of candida albicans growth on: 1- Heat polymerized resin and auto polymerized resin bases non vacuum mixed 2-Heat polymerized resin and autopolymerized resin bases vacuum mixed 3- Trial VLC resin base
