Comparison of in vivo and in vitro models to evaluate pulp temperature rise dur...
Runnacles,Patricio; Arrais,Cesar Augusto Galvão; Maucoski,Cristiane; Coelho,Ulisses; De Goes,Mario Fernando; Rueggeberg,Frederick AllenAbstract Objectives: To measure and compare in vivo and in vitro pulp temperature (PT) increase (ΔTEMP) over baseline, physiologic temperature using the same intact upper premolars exposed to the same Polywave® LED curing light. Methodology: After local Ethics Committee approval (#255,945), local anesthesia, rubber dam isolation, small occlusal preparations/minute pulp exposure (n=15) were performed in teeth re...
Silorane- and high filled-based"low-shrinkage" resin composites: shrinkage, fle...
Arrais,Cesar Augusto Galvão; Oliveira,Marcelo Tavares de; Mettenburg,Donald; Rueggeberg,Frederick Allen; Giannini,MarceloThis study compared the volumetric shrinkage (VS), flexural strength (FS) and flexural modulus (FM) properties of the low-shrinkage resin composite Aelite LS (Bisco) to those of Filtek LS (3M ESPE) and two regular dimethacrylate-based resin composites, the microfilled Heliomolar (Ivoclar Vivadent) and the microhybrid Aelite Universal (Bisco). The composites (n = 5) were placed on the Teflon pedestal of a video-...
Light-activation through indirect ceramic restorations: does the overexposure c...
Bueno,Albano Luis Novaes; Arrais,Cesar Augusto Galvão; Jorge,Ana Carolina Tedesco; Reis,Andre Figueiredo; Amaral,Cristiane MarioteOBJECTIVES: This study evaluated the effects of light exposure through simulated indirect ceramic restorations (SICR) on hardness (KHN) of dual-cured resin cements (RCs), immediately after light-activation and 24 h later. MATERIAL AND METHODS: Three dual-cured RCs were evaluated: Eco-Link (Ivoclar Vivadent), Rely X ARC (3M ESPE), and Panavia F (Kuraray Medical Inc.). The RCs were manipulated in accordance to th...
Degree of conversion of adhesive systems light-cured by LED and halogen light
Arrais,Cesar Augusto Galvão; Pontes,Fenelon Martinho; Santos,Luis Presley Serejo dos; Leite,Edson Roberto; Giannini,MarceloThis study evaluated the effect of blue light emitting diode (LED) and quartz tungsten halogen (QTH) on the degree of conversion (DC) of an etch-and-rinse Single Bond adhesive system (SB) and a mixture composed of primer solution and resin bond from Clearfil SE Bond self-etching adhesive system (CB) using Fourier transform infrared analysis (FTIR). Adhesives were applied to potassium bromide pellet surfaces and...
