36-Month Clinical Evaluation of a Universal Adhesive

One hundred sixty‐five NCCLs in 35 patients (13 female, 22 male) with at least 3 lesions were included in this study. Three groups were formed according to adhesive strategies used (n=55): selective‐etch mode; etch‐and‐rinse mode (ER); or self‐etch (SE) mode of a universal adhesive, Single Bond Universal. The same nanofilled resin composite, Filtek Ultimate was used for all restorations by a single operator. The restorations were evaluated by two calibrated examiners at baseline and at 6‐, 12‐, 18‐, 24‐ and 36‐ months in accordance with the modified USPHS criteria. The Chi‐square test was used for intergroup, the Cochran Q test was used for intragroup comparison.
