The aim of this study was to evaluate the adhesion and initial colonization of S. mutans on the surface of novel composite resins during three experimental periods. Biofilms were formed on specimens of Enamel Plus HRI (Hri), FiltekTM Silorane (Si), Tetric EvoCeram® Bulk Fill (Te), KaloreTM (K), and FiltekTM Z250 (Z) (n=4/experimental period). After 4, 8 and 24 hours, the specimens were assessed for bacterial colony forming unit (CFU/mm2) levels and scanned by electron microscopy. All material surfaces showed a similar susceptibility to bacterial adhesion at 4 hours (p>0.05). The amount of microorganisms in the formed biofilms increased at 8 hours for all groups (p 0,05). La cantidad de microorganismos en las biopelículas formadas aumentó a las 8 horas para todos los grupos (p
