Despite the wide use of dental implants, the understanding of the mechanism(s) of bacterial attachment to implant surfaces and of the factors that affect such attachment is limited. In this study, the attachment of oral bacteria--including Streptococcus sanguis, Actinomyces viscosus, and Porphyromonas gingivalis--to titanium (Ti) discs with different surface morphology (smooth, grooved, or rough) was examined by scanning electron microscopy (SEM). The most bacterial attachment was observed on the rough BSA-coated Ti surfaces. The smooth surfaces promoted poor attachment for S. sanguis and A. viscosus. However, P. gingivalis attached equally well to both the smooth and grooved coated Ti surfaces, based on direct cell quantitation and examination with SEM. Cell-surface fimbriae (which may play a role in adhesion) of both A. viscosus and P. gingivalis observed were associated with the Ti surfaces. Ti implant surface characteristics appeared to influence oral bacterial attachment in vitro. The in vitro attachment system has proven its usefulness for future bacterial attachment studies with model implant surfaces.
