Abstract
To evaluate the clinical performance of a universal adhesive system (Futurabond U, Voco) when applied following different adhesive strategies in non-carious cervical lesions (NCCLs) after 5 years. Fifty participants were included. Futurabond U (Voco) was applied in NCCLs using four adhesive strategies (n=50 each): only self-etch (SE); selective enamel etching+self-etch (SET+SE); etch-and-rinse with dry dentin (ERD); and etch-and-rinse with wet dentin (ERW). All cavities were restored with Admira Fusion composite resin (Voco). Restorations were evaluated after 1, 3, and 5 years using the World Federation criteria (FDI) and the modified United States Public Health Service (USPHS) criteria. After 5 years, retention rates were 81% (65.8-90.5) for SE, 87% (73.2-94.4) for SET+SE, 84% (69.6-92.6) for ERD, and 78% (63.6-88.9) for ERW (p>0.05). Thirty-five restorations were considered to have minor discrepancies in marginal adaptation at the 5-year recall (14 for SE, 9 for SET+SE, 6 for ERD, and 6 for ERW; p>0.05). Sixteen restorations were detected as a minor marginal discoloration (6 for SE, 4 for SET+SE, 1 for ERD, and 5 for ERW; p>0.05) and one restoration showed a recurrence of caries (1 for ERW; p>0.05) at the 5-year recall. No restorations showed postoperative sensitivity after 5 years. NCCLs restorations using a universal adhesive showed satisfactory clinical performance after 5 years, regardless of the adhesive strategy.
