The remineralization of sites of incomplete resin infiltration in acid-etched dental tissue was analyzed. Unexposed, buccal class V preparations with enamel cavosurface margins were performed in 16 human premolars scheduled for orthodontic extraction, under a protocol approved by the ethical committee. Incompletely infiltrated regions within the acid-etched dentin were identified by extensive silver deposition zones from unstained, undermineralized sections, over-dried, and over-etched gropus. Collagem fibrils without the protection of adhesive resin, storage in oral environment, could be digested by enzymes as metalloproteinases (MMP). The used adhesive system was unable to infiltrate completely into demineralized dentin.
