Tensile Bond Strength and Curing Gap Formation of a Dentin Bonding Resin

Abstract: Tensile bond strength and contraction gap tests were carried out using a new dentin bonding resin in association with various dentin conditioning and priming materials in vitro. For the tensile bond test, significant differences were found between the nonconditioned and conditioned dentin, and the primed and non-primed dentin surfaces. The strongest bond was obtained using a combination of phosphoric acid conditioning and priming with HEMA in glutaraldehyde at 151.3kgf/cm2. Gap test results showed the presence… Show more

“…Polymerization shrinkage cannot be avoided, and the development of adhesive systems involves a constant battle against this problem. Polymerization shrinkage induces contraction stress in the polymerized resin composite, which could weaken the adhesion at the compositedentin interface [4][5][6][7][8][9] . Many factors affect polymerization shrinkage: size of restoration, C-factor of cavity, and filling technique(incremental or bulk) .…”

“…However, polymerization of the resin matrix phase causes the monomer to shrink when converted to polymer. In three-dimensional cavity preparations, resin shrinkage stress leads to gap formation between the filling material and cavity walls [1][2][3] . Such gaps and subsequent microleakage may cause postoperative sensitivity 4) and secondary caries 5) .…”

“…É sabido que a união entre resina e dentina criada pelos adesivos hidrofílicos contemporâneos deteriora-se com o tempo (ARMSTRONG; KELLER; BOYER, 2001;BURROW et al, 1996;De MUNCK et al, 2003;YU, 1995), ocorrendo a hidrólise e degradação da interface de união entre o material restaurador e a dentina (BURROW et al, 1993;Van MEERBEEK et al, 1999) PERDIGAO et al, 1997).…”
