The mTBS values of each group were registered 24 h and one year after adhesive system application and resin composite block build-up (n=30). Data were analyzed by the t-test (p<0.05). <strong>Results</strong>: When both adhesive systems were compared, there was no statistically significant difference when they were applied following wet bonding (p>0.05). However, the dry bonding reduced μTBS values of the Adper Single Bond 2 adhesive (p<0.05). Regarding storage time, both groups presented similar μTBS values at 24 h and one year (p>0.05). <strong>Conclusions</strong>: Therefore, the Scotchbond Universal Adhesive can be applied to dry or wet dentin without compromising the etch-and-rinse bonding quality and the durability of the restorations.</p>}, journal={Brazilian Journal of Oral Sciences}, author={Leite, Maria Luísa de Alencar e Silva and Charamba, Caroline de Farias and Lima, Renally Bezerra Wanderley e and Meireles, Sônia Saeger and Duarte, Rosângela Marques and Andrade, Ana Karina Maciel de}, year={2020}, month={Mar.}, pages={e201662} }
