Dentin Sealing and Bond Strength Evaluation of Hema-Free and Multi-Mode Adhesiv...
Bacelar-Sá,Renata; Giannini,Marcelo; Ambrosano,Glaucia Maria Bovi; Bedran-Russo,Ana KarinaAbstract This study evaluated the effect of dentin biomodification on the bond strength (BS) and sealing ability (SA) of HEMA-free and multi-mode adhesives after 24 h and 6 months of water storage. Four adhesives were tested: two multi-mode (Scotchbond Universal - SU, and Prime & Bond Elect - PB) and two HEMA-free (All-Bond 3 - AB, and G-Aenial - GA). Human third molars were selected and dentin was treated with...
Radiant exposure effects on physical properties of methacrylate - and silorane-...
Catelan,Anderson; Kawano,Yoshio; Santos,Paulo Henrique dos; Ambrosano,Gláucia Maria Bovi; Bedran-Russo,Ana Karina; Aguiar,Flávio Henrique BaggioAIM: To evaluate the effect of different radiant exposures on the degree of conversion (DC), Knoop hardness number (KHN), plasticization (P), water sorption (WS), and solubility (S) of different monomer resin-based composites. METHODS: Circular specimens (5 x 2 mm) were manufactured from methacrylate and silorane composite resins, and light-cured at 19.8, 27.8, 39.6, and 55.6 J/cm2, using second-generation LED ...
Impact of light-curing time and aging on dentin bond strength of methacrylate- ...
Catelan,Anderson; Soares,Giulliana Panfiglio; Bedran-Russo,Ana Karina; Lima,Débora Alves Nunes Leite; Marchi,Giselle MariaAIM: To evaluate the impact of different light-curing times on dentin microtensile bond strength of two restorative systems after 24 h and 6 months of water storage. METHODS: Standardized Class II preparations were performed in 56 freshly-extracted human molars (n = 7), restored with methacrylate- or silorane-based restorative systems, and light-cured using a light-emitting diode at 1390 mW/cm2 by the recommend...
