Webbiofilm matrix and multilayer biofilm formation (Kierek & Watnick, 2003). The second step in biofilm formation requires the cell to form at least a semipermanent association with the surface. This step is frequently referred to as the ‘attachment phase’. Many authors have broken this down into a reversible and an irreversible phase, but with WebApr 10, 2024 · The aim of this study was to evaluate the adhesion and biofilm formation of Candida albicans (C. albicans) on conventionally fabricated, milled, and 3D-printed denture base resin materials in order to determine the susceptibility of denture contamination during clinical use.
