Clinical behavior of universal adhesives in non-carious cerv
This randomized, double-blind clinical trial, evaluated the behavior of two universal adhesives used in the etch-and-rinse (ER) or self-etch (SE) approach in non-carious cervical lesions (NCCLs). Two hundred and eleven NCCLs were selected in 54 participants and randomly allocated into four experimental groups: Scotchbond Universal Adhesive – SBU (3M Oral Care) and Prime & Bond Elect – PB (Dentsply Sirona) used in ER and SE modes. Two trained operators placed all resin composite restorations (Filtek Z250, 3M Oral Care). Restorations were evaluated at baseline and after 6 months using both FDI and USPHS modified criteria by a blinded calibrated examiner. Kruskal-Wallis and Mann-Whitney U non-parametric tests were used to compare the restoration failures among experimental groups.

Statistically significant differences were found among groups regarding failures. PB-SE presented more failures than other experimental groups. No significant difference was found between any other pair of groups (p>0.05).

The etch and rinse approach affected the clinical performance of Prime and Bond Elect. For this material, the self-etch approach generated lower criteria scores after a six-month follow-up. The bonding strategy did not influence Scotchbond Universal Adhesive clinical performance. (RBR-2GQMVF)

The clinical behavior of mild universal adhesive Prime & Bond Elect depends on the bonding strategy. The etch-and-rinse approach is recommended for this adhesive system. Scotchbond Universal Adhesive can be used in both bonding strategies without impairing clinical performance.
