Resumen
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) The aims of this study were to evaluate the ultimate tensile strength (UTS) and elastic modulus (E) of adhesives, and primer/adhesive mixtures after aging for 6 months in water or oil; and to compare silver uptake patterns under the TEM. A one-step self-etching adhesive (One-up Bond F: OB), two two-step self-etching primers (SE Bond: SE and Protect Bond: CP), and two etch-and-rinse systems (Single Bond: SB and Prime&Bond NT: PB) were used. Bonding and primer solutions of self-etching systems were also mixed (SE+P and CP+P). Most adhesives presented decreased UTS after water-storage. Similar or increased UTS was observed after oil storage. Except for SB, E values did not change after water-storage, but they increased after storage in oil. OB, CP+P and SE+P presented more silver uptake. The effects of water-storage were material-dependent, and significantly, affected the mechanical properties and silver uptake patterns of adhesives. 29 6 697 705 Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) National Institute of Dental and Craniofacial Research, Bethesda, MD [DE016116] Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) CAPES [BEX2462/03-6] National Institute of Dental and Craniofacial Research, Bethesda, MD [DE016116]
