2. Influence of curing protocol and ceramic composition on the degree of conversion of resin cement
Abstract Due to increasing of aesthetic demand, ceramic crowns are widely used in different situations. However, to obtain long-term prognosis of restorations, a good conversion of resin cement is necessary. Objective: To evaluate the degree of conversion (DC) of one light-cure and two dual-cure resin cements under a simulated clinical cementation of cerami

3. Comparing depth-dependent curing radiant exposure and time of curing of regular and flow bulk-fill composites
Abstract The effect of restoration depth on the curing time of a conventional and two bulk-fill composite resins by measuring microhardness and the respective radiosity of the bottom surface of the specimen was investigated. 1-, 3- and 5-mm thick washers were filled with Surefil SDR Flow–U (SDR), Tetric EvoCeram Bulk Fill-IVA (TEC) or Esthet-X HD–B1 (EHD

5. The Influence of a Translucent Fiberglass Post on the Polymerization of Dual Cure Resin Cement Analyzed by Electron Paramagnetic Resonance
AbstractElectron Paramagnetic Resonance (EPR) was used as an alternative method to study the conversion degree of dual cure resin cement and verify the influence of prefabricated translucent fiberglass post on the dual cure resin cement polymerization at different restoration points. The post cementation of White Post DC (FGM, Joinville, SC, Brasil) was simu

6. Effects of curing protocol and storage time on the micro-hardness of resin cements used to lute fiber-reinforced resin posts
OBJECTIVES: To determine the micro-hardness profile of two dual cure resin cements (RelyX - U100®, 3M-eSPe and Panavia F 2.0®, Kuraray) used for cementing fiberreinforced resin posts (Fibrekor® - Jeneric Pentron) under three different curing protocols and two water storage times. MATERIAL AND METHODS: Sixty 16mm long bovine incisor roots were endodontical

7. Effect of pre-heated dual-cured resin cements on the bond strength of indirect restorations to dentin
This study evaluated the effects of resin luting agents (LA) polymerized using increased temperature on the in vitro microtensile bond strength (mTBS) of indirect restorations to dentin. The occlusal dentin surfaces of 40 human third molars were exposed and flattened. The teeth were assigned to 8 groups (n = 5) according to the LA temperature (25°C o r 50°

8. ENTRE AS INTERFACES DAS RACIONALIDADES DA SAÚDE: Por que terapia floral? / BETWEEN THE INTERFACES OF THE RATIONALITIES OF HEALTH: Why floral therapy?
Western science, today, is science that has been instituted and comes in the first place, with characteristics such as objectivity, measurement and Cartesianism. This study brings to light, in a way, an old debate about what science is. And, behind that backdrop, reveals itself the central question: what reasons have led some doctors, immersed in the biomedi

9. Effect of irradiation times on the polymerization depth of contemporary fissure sealants with different opacities
The aim of this study was to evaluate the depth of curing of 10 contemporary blue light-activated dental flowable materials at several opacities, influenced by different irradiation times using FT-IR spectroscopy. Fifty-five specimens (n = 5) with a 5-mm diameter and 1-mm thickness of translucent (Opallis Flow T), yellowed (Master Flow A2; Opallis Flow A2; N

10. Pre-heated dual-cured resin cements: analysis of the degree of conversion and ultimate tensile strength
This study evaluated the degree of conversion (DC) and ultimate tensile strength (UTS) of dual-cured resin cements heated to 50º C prior to and during polymerization. Disc- and hourglass-shaped specimens of Rely X ARC (RX) and Variolink II (VII) were obtained using addition silicon molds. The products were manipulated at 25º C or 50º C and were subjected

11. Effect of curing mode on the hardness of dual-cured composite resin core build-up materials
This study evaluated the Knoop Hardness (KHN) values of two dual-cured composite resin core build-up materials and one resin cement exposed to different curing conditions. Two dual-cured core build-up composite resins (LuxaCore®-Dual, DMG; and FluoroCore®2, Dentsply Caulk), and one dual-cured resin cement (Rely X ARC, 3M ESPE) were used in the present stud

12. Dual-curing, self-adhesive resin cement: influence of the polymerization modes on the degree of conversion and microhardness
RelyX TM Unicem, dual-curing self-adhesive resin cement, was tested in order to evaluate the degree of conversion (DC) and Vickers microhardness (VMH). The specimens were prepared into 4 groups (GR). For GR1, the specimens were irradiated with 500 mW.cm-2 during 20 seconds while for GR3 the same intensity was used but the irradiation time was 40 seconds. The
