The objective of this multi-centric, double-blind, randomized clinical trial was to evaluate the clinical performance of a new universal adhesive system (Futurabond U, Voco GbmH, Germany) when applied with different application strategies over a period of six months. For this, 200 restorations were performed on non-carious cervical lesions using the adhesive Futurabond U in the four adhesive strategies (n=50 per group): self-etch without previous conditioner (SEE); self-etch associated with selective enamel etching (SET); etch-and-rinse with dry dentin (ERDry) and; etch-and-rinse with wet dentin (ERWet). After the use of the adhesive system, the cavities were restored with Admira Fusion composite resin (Voco GmbH). After 6 months of clinical performance, these restorations were evaluated according to FDI criteria in the following items: retention/fracture, marginal adaptation, marginal staining, postoperative sensitivity and caries recurrence. Seven restorations were lost/fractured after six months of clinical evaluation (2 in the SEE group, 1 in the SET group, 1 in the ERDry group, and 3 in the ERWet group). The retention rates for six months (95% confidence interval) were 96% (86%-98%) for the SEE group, 98% (89%-99%) for the SET group, 98% (89%-99%) for the ERDry group and 94% (83%-97%) for the ERWet group, with no statistical difference identified between any pair of groups (p> 0.05). Twenty-four restorations presented small marginal adaptation defects at the six-months evaluation recall, and all of them were considered clinically acceptable. The clinical performance of the universal adhesive Futurabond U associated to Admira Fusion unidoses resin composite was found to be promise after 6-month of clinical evaluation when applied in noncarious cervical lesions and it was not depending on the bonding strategy employed.
