“…Several studies have focused on glazes, and have shown an improvement in the surface texture and the optical properties of restorations. 1,2 However, very rapid wear of the material, 3 as well as the lack of adhesion of the underlying composite resin to the enamel, 4 have been observed.…”

The application of Fortify (Bisco, Lombard, IL), an unfilled resin, to the surface of composite resin restorations is intended to fill in defects in the surface that persist despite polishing, improve marginal integrity, and increase these materials' resistance to abrasion. The aim of this study was to observe the surface texture by scanning electron microscopy and measure the microhardness of the surface. For each sample of composite resin covered with glaze, 40 measurements were made of the thickness of the resin. Measurements of the Vickers microhardness included three samples of composite resin, three samples of glaze, and six samples of composite resin covered with glaze. A relationship was established between microhardness and thickness. Scanning electron microscopy showed a noticeable improvement in the surface texture. Nevertheless, areas were seen in which glaze seemed very thin or even completely absent. Measurements of the thickness ranged from 0-70 microm. The mean microhardness of composite resin was 65.8 +/- 0.7, while the mean hardness of glaze was 7.3 +/- 0.7. The microhardness of the double layer was reduced, depending on the thickness of the glazing resin. The capacity of glaze to mask surface defects of composite resin was shown, but it was difficult to obtain a regular surface with liquid resin. The application of this product caused a decrease of the microhardness of the composite resin's surface.

“…Glaze or coating materials for composites and enamel are retained mostly by mechanical bonding (8,9). Their intended effect on the surface properties of the composite is limited owing to reduced polymerization and wear resistance (10).…”

The water sorption, solubility, hardness, and color stability of thin specimens of auto-polymerized and heat-polymerized denture base polymers with and without a UV light-polymerized coating material were investigated. The specimens were saturated after storage in water for 24 h. The thin coating reduced the leakage of soluble ingredients from an auto-polymerized denture base material. The coated materials had increased surface hardness compared with the uncoated, but the difference in hardness was reduced on water uptake. A continuous increase in yellowing of the auto-polymerized coated and uncoated specimens was observed when stored in water at 37 degrees C.

“…However, as LCCMs have low resistance to abrasion because of the smaller (or without) quantity of inorganic load incorporated into the organic matrix, they easily become worn when submitted to occlusal contacts and the restoration soon loses the characterization. [6][7][8] To prevent the early loss of the effect of characterization, it is recommended that LCCMs should be covered with an external layer of resin composite. This modification in the application of LCCMs is what characterizes the intrinsic technique.…”
