[The influence of the chemo-mechanical removal of the smear-layer and the use of a dentin adhesive on microleakage of composite resin restorations]. / Influencia de la remoción químico-mecánica del "smear-layer" y la presencia de un adhesivo dentinario en la microfiltración de restauraciones de resina compuesta.

We present an "in vitro" study of microfiltration in composite resin restorations with a perimetral seal placed totally in cement. We compare the sealing capability of a dentin adhesive (ScotchBond I) used in two ways: habitual, without conditioning dentin and conditioning it by means of the Caridex system. This produced no increasing of sealing capability under the study conditions.
