The aim of this study was to evaluate the 6- and 12-month clinical performance of four adhesion strategies from the same manufacturer (Kerr) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One). The composite resin Filtek Supreme Ultra (3M ESPE) was placed incrementally. The restorations were evaluated at baseline, after 6 months, and after 12 months, using both the FDI and the USPHS-modified criteria. Statistical analyses were performed with Friedman repeated measures, ANOVA by rank, and the McNemar test for significance in each pair (α = 0.05). Six restorations (2 for OFL, 1 for OSP, 2 for XTR, and 1 for AIO) were lost at 12 months (P > 0.05 for both evaluation criteria). Marginal staining was observed in seven restorations using the FDI criteria (P > 0.05) and three restorations using the USPHSmodified criteria (P > 0.05). Eight restorations (2 for OSP, 3 for XTR, and 3 for AIO) were classified as Bravo for marginal adaptation using the USPHSmodified criteria (P > 0.05). However, 62 restorations (14 for OFL, 12 for OSP, 15 for XTR, and 21 for AIO) were classified as Bravo using the FDI criteria (P > 0.05). The four adhesion strategies showed similar clinical retention at 6 and 12 months. The FDI evaluation criteria tend to be more sensitive than the USPHS-modified criteria.
