The influence of glazing and polishing on ceramic surface roughness and bacterial adhesion / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the influence of polishing and glazing on ceramic surface roughness and bacterial adhesion to the resulted surfaces.</p><p><b>METHODS</b>The surface of the ceramic plates were tested and analyzed by atomic force microscope. The influence of resulted surface on Streptococcus mutans adhesion were also evaluated.</p><p><b>RESULTS</b>The ceramic surface became much smoother after polishing with diamond paste or self-glazing. A positive correlation between surface roughness and bacterial adhesion were observed. Compared with surfaces polished with rubber-wheel, surfaces polished with diamond paste or self-glazing reduced bacterial adhesion to the surface (P<0.05).</p><p><b>CONCLUSION</b>Polishing with diamond paste could be an alternative to self-glazing on ceramic surface roughness and bacterial adhesion.</p>
