2-YEAR CLINICAL-EVALUATION OF DENTIN BONDING SYSTEMS

Purpose: To clinically evaluate dentin bonding systems. Materials and Methods: Eighty Class V carious lesions were prepared and restored wit h four different adhesive systems: Clearfil Liner Bond/Clearfil Photo Anterior, Scotchbond Multi-Purpose/Silux Plus, Syntac/Heliomolar, and Gluma 2000/Pekalux. All restorations were evaluated at baseline, after 1 year and 2 years using the USPHS criteria. Results: No significant difference was noticed between the tested materials after 1 year. Howe ver, the 2-year results revealed that the restorations of Groups 1 and 2 were superior to restorations of Groups 3 and 4. Adhesive systems t hat remove the smear layer and have a substantial lining function perf ormed better than those that only modify the smear layer.
