Three extrinsic characterizations (2\u00a0mm thick) were applied to the 3D\u2010printed resin specimens: one regular\u2010viscosity (RV) and two low\u2010viscosity (LV49, LV30), and light\u2010cured. The heat\u2010polymerized resin group (STG) was fabricated and characterized using a compression\u2010molding technique. Color coordinates and color stability (\u0394<jats:italic>E<\/jats:italic><jats:sub>00<\/jats:sub>) were measured using a colorimeter; surface roughness (<jats:italic>R<\/jats:italic><jats:sub>a<\/jats:sub>) was assessed using an optical profilometer; and microbial adhesion (<jats:italic>Candida albicans<\/jats:italic>, log CFU\/mL) was evaluated before and after 20,000 brushing cycles. Color and roughness data were analyzed using the Kruskal\u2013Wallis test and the Wilcoxon signed\u2010rank test, while microbial adhesion was analyzed using one\u2010way ANOVA followed by Tukey's post hoc test (<jats:italic>\u03b1<\/jats:italic>\u00a0=\u00a00.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>STG and LV49 exhibited greater color changes than did LV30 (<jats:italic>p<\/jats:italic> &lt; 0.05), but all groups remained within clinically acceptable limits (\u0394<jats:italic>E<\/jats:italic><jats:sub>00<\/jats:sub> \u2264 2.25).
