Candidiasis is common in denture wearers. Candida albicans is a type of yeast that is common member of the human gut flora. Infection of denture materials with Candida albicans is common and contributes to denture stomatitis.  Thus, this study is being carried out to find which denture is more susceptible to candidal growth and to find a material that is better to maintain by denture wearers.The aim of the study was to compare the growth of Candida albicans in permanent denture base materials such as heat cure resin and permanent self cure resin.In the present experimental study, 10 square shaped (10 × 10 × 1 mm) heat cure and self cure resin acrylic plates were prepared (5 samples for each group). The specimens were kept in a flask containing physiological serum (NaCl 0.85%), sterilized in an autoclave at 121oC for 15 minutes and incubated at 4oC for further adherence testing. The resin specimens were immersed in distilled water in order to promote the maximum water sorption to prevent, when in culture, the occurrence of distortion and the release of residual monomer after polymerization.Candida albicans were grown and cultured in experimental heat and self cure resins and the slide count and serial dilutional test were done .The growth of Candida albicans was more in permanent self cure resin when compared to conventional heat cure resin.There was a statistically significant difference between the levels of colonization of Candida albicans between the test groups (P<.05The growth of Candida albicans was seen more in permanent self cure resin plates than heat cure resin plates. Thus, even though permanent self cure resin plates are easier to process, conventional heat cure resin is less susceptible to Candidal growth and easier to maintain by denture wearers.
