Bacterial adhesion on different dental material surfaces

1. Klemen Bohinc, Faculty of Helth Sciences, University of Ljubljana, Slovenia, Slovenia

In my presentation I will consider the bacterial adhesion on different
dental material surfaces like amalgam, Chromasit, Cr-Co alloy, two types
of ceramics, resin-based composite, Au-Pt alloy, and tooth. All surfaces
were characterized by measuring surface roughness, surface
hydrophobicity and zeta potential. We consider the adhesion of
Streptococcus mutans which is a primary colonizing bacterium in the oral
cavity and most important cause for caries. Bacteria attached to the
dental surfaces were fixed and examined with a scanning electron
microscopy. From micrographs the bacterial adhesion rate was determined.
We showed that the bacterial adhesion rate on amalgam and Chromasit was
extremely low. On contrary on both alloys and ceramics the bacterial
adhesion rate increased substantially, the greater adhesion rate was
measured on tooth surfaces.
