title: [Comparative scanning electron microscopic studies on the width of the marginal cleft of various composites and on the accuracy of reproduction of the clefts with various casting materials].
abstract: Poor results concerning the formation of marginal clefts were obtained with Adaptic and Concise; all composites utilizing the etching technique showed a homogeneous transition between enamel and filling. It should be noted that our findings were taken from extracted teeth 24 hours after the filling. No statement therefore can be made about the long-term behavior of these filling materials in the mouth.
