[Quality of marginal sealing of Evicrol fillings when using dental adhesives in vitro].

Abstract

The quality of the marginal sealing of fillings made from Evicrol in vitro was investigated by means of a couloured indicator. The close adherence of the composite filing to the surface of the tooth was ensured by the by micro retention treatment of the marginal enamel and different dentin adhesives. The thermal strain of filling materials and their combination with the tooth, corresponding roughly to conditions in the oral cavity, was modelled by cyclic temperature changes using a special apparatus designed by the authors.
