Abstract
Dental implant failure is commonly associated
to dental plaque formation. This problem starts with bacterial
colonization on implant surface upon implantation.
Early colonizers (such as Streptococcus sanguinis) play a
key role on that process, because they attach directly to the
surface and facilitate adhesion of later colonizers. Surface
treatments have been focused to improve osseointegration,
where shot-blasting is one of the most used. However the
effects on bacterial adhesion on that sort of surfaces have
not been elucidated at all. A methodological procedure to
test bacterial adherence to titanium shot-blasted surfaces
(alumina and silicon carbide) by quantifying bacterial
detached cells per area unit, was performed. In parallel, the
surface properties of samples (i.e., roughness and surface
energy), were analyzed in order to assess the relationship
between surface treatment and bacterial adhesion. Rather
than roughness, surface energy correlated to physicochemical
properties of shot-blasted particles appears as
critical factors for S. sanguinis adherence to titanium
surfaces.
