[Modification of the filling margin by ultrasonics].
On 117 extracted teeth the border closure of polished fillings with various materials was examined after exposure to the action of ultrasound. The estimation of the depth of roughening in the area of the border of the filling was achieved with the help of the Förster profilograph. In addition we present the results obtained by the REM technique. It was shown that the least damage of the border closure was in teeth filled with composites.
