title: Adherence of oral streptococci to composite resin of varying surface roughness.
abstract: The adherence of oral bacteria to composite resins plays an important role in the development of secondary caries. The present study deals with the adherence to composite resin having various surface roughness of S.oralis, which is frequently isolated from composite resin squares attached to maxillary first molars. available commercial resin was used in this experiment. In vitro bacterial adhesion test was carried out under a sucrose independent conditions. The surface roughness values of each specimen ranged between 0.2 micron and 3.0 microns. No relationship was observed between the surface roughness values and bacterial adhesion because S. oralis adhered firmly to the filler particles of all composite resin surfaces.
