[In vitro studies on a new fissure sealant (Concise Resin)].

The use of Concise resin--belonging to the Concise Enamel Bond System--is reported by the sealing of fissures of the premolars and molars under in vitro circumstances. On the basis of the gained results by polarisationmicroscopic and light microscopic examination of the marginal closure of the materials and his placement in the fissures, it looks suitable for using under in vivo circumstances too.
