Evaluation of the effect of new generation denture base materials aged in artificial saliva at different pH levels on surface roughness and Candida albicans adhesion

Aging at different pH values caused surface changes in denture base materials and differences in C. albicans adhesion. Although there is an increase in surface roughness in all groups, these values are lower than the plaque accumulation threshold. The highest C. albicans adhesion was observed in heat-cured PMMA samples. Considering both roughness values and Candida adhesions, it is concluded that the new generation denture base materials are suitable for clinical use and should be widely used.
