[The adhesiveness and surface quality of 3 different filling materials studied by means of the Hommel tester and REM films].
Three different filling materials (amalgam, composite resin [Adaptic], and silicate) were studied in terms of their adhesion, surface quality, and hardness. Using REM films, the different cleft widths between filling and tooth were demonstrated. The narrowest fissure width was observed with composite resin fillings. The Hommel tester showed that surface roughness with amalgam and composite resin could be significantly smoothed by polishing; the silicate fillings could not be polished as easily. The mean for surface hardness, measured according to Brinell, is somewhat higher for silicate; the means for composite resin and amalgam surface hardness are the same.
