Abstract
The effect of a glazing compound to seal composite resins in an effort to prevent microleakage and enhance the durability of composite restorations has been investigated. The adhesive properties of the glazing compound in vivo was determined by restoring 40 permanent teeth with a commercially available composite resin. The restorations were covered with a thin layer of glazing compound extending 1.5-2mm on surrounding etched enamel. Clinical evaluations were to be performed at 3 month intervals. It was observed however that most of the restorations had lost the glazing compound after 3 months. In vitro investigations illustrated that the adhesive layer covered the composite restoration in less than 50% of the cases, and that they displayed an uncovered cavosurface angle with glazing compound interspersed along the surface. Scanning electron microscopy provided a reliable understanding of the enamel-sealant composite interface, and as a consequence a reliable way of determining the retention of the sealant from a mechanical standpoint.
