Objective: To determine the adherence of Candida albicans to polyamide and acrylic resins. Materials and Methods: In this experimental in vitro study 12 dental prostheses were made, 6 acrylic partial dentures which were elaborated under the heat-curing technique and 6 prosthesis made of polyamide by injection; 2 mm samples with irregular borders were taken from different areas of the prosthesis for analysis and variables such as temperature, heating time, polishing time, material used to shine, presence of porosities, accessory and abrasive used to remove excess were evaluated; the samples were held in distilled water for two days to remove the monomer excess and then they were incubated in a Candida albicans suspension strain ATCC 10231 and evaluated by scanning electron microscopy (SEM). Results: Porosities, cracks, blastospore and pseudohyphae were observed on the resins made from acrylic. The same results were observed on the samples made from polyamide to a lesser extent. Conclusion: Adhesion was found on the 12 samples evaluated. A statistically significant association was found between polishing type and abrasive type with a value of (p < 0.05).
