This study aimed to determine the influence of surface roughness (Ra), surface free energy (SFE), saliva, and bacteria on Candida adhesion to denture materials. The Ra and SFE of 2 acrylic resin specimens and 2 denture liner specimens were measured and assayed in a flow chamber for bacteria culture perfusion plus Candida albicans or C glabrata cultures. Adhesion was determined by counting under light microscopy. Candida adhesion showed significant differences depending on the factors involved. The overall colonization was significantly decreased by saliva and influenced by bacteria. Candida adhesion was strongly affected by Ra, saliva, and bacteria, but not by SFE.
本研究旨在确定表面粗糙度（Ra）、表面自由能（SFE）、唾液和细菌对念珠菌黏附于义齿材料的影响。对2个丙烯酸树脂标本和2个义齿衬垫标本的Ra和SFE进行了测量，并在流动腔中进行细菌培养灌注以及白色念珠菌或光滑念珠菌培养的测定。通过光学显微镜计数来确定黏附情况。念珠菌的黏附因相关因素的不同而存在显著差异。唾液可显著减少总体定植，且念珠菌黏附受细菌影响。念珠菌的黏附受到Ra、唾液和细菌的强烈影响，但不受SFE的影响。
