1. Influence of activation mode, fatigue, and ceramic interposition on resin cements’ diametral tensile strength
Abstract This study evaluated the influence of activation modes, on Diametral Tensile Strength (DTS) of dual cured resin cements subjected to a Mechanical Fatigue test (MF). Four dual-cured resin cements (RelyX UNICEM [U], RelyX ARC [A], ENFORCE [E] and Nexus 2 [N]) were activated by three different curing modes as follows: Self-Curing (SC), Dual Cure activa

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. 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

4. Swelling of self-adhesive resin cement increases long-term push-out bond strength of fiber post to dentin
Abstract Aim: To evaluate the long-term post push-out bond strength to dentin, water sorption, solubility and swelling of conventional and self-adhesive dual-cure resin cements. Methods: Forty-eight bovine roots were prepared for fiber post cementation with RelyX ARC and RelyX U100. According to resin cement and storage time (24 h and 6 months), 4 groups

5. Influence of 2% chlorhexidine on pH, calcium release and setting time of a resinous MTA-based root-end filling material
The addition of chlorhexidine (CHX) to a resinous experimental Mineral Trioxide Aggregate (E-MTA) based root-end filling material is an alternative to boost its antimicrobial activity. However, the influence of chlorhexidine on the properties of this material is unclear. The aim of this study was to evaluate the influence of 2% chlorhexidine on the pH, calci

6. Effects of layering technique on the shade of resin overlays and the microhardness of dual cure resin cement
The purpose of this study was to assess the color of layered resin overlays and to test the early microhardness of dual cure resin cement (DCRC) light cured through the layered resin overlays. Resin overlays of 1.5 mm thickness were fabricated with the A3 shade of Z350 (Group 1L), the A3B and A3E shades of Supreme XT (Group 2L), and the A3, E3, and T1 shades

7. Avaliação da influência do tipo de cerâmica e protocolo de ativação no grau de conversão de cimentos resinosos por meio da espectroscopia Raman / Evaluation of the ceramic type and curing protocol on the degree conversion of resin cements used to lute full ceramic crowns by Raman spectroscopy
É crescente a aplicação dos cimentos à base de resina em próteses em cerâmica por exibirem propriedades estéticas e biomecânicas superiores aos cimentos convencionais. O presente estudo teve por objetivo avaliar o grau de conversão (GC) de quatro cimentos resinosos, sendo um com modo de polimerização físico (ChoiceTM 2/Bisco Inc), 2 com modo de p

9. 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

10. 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°

11. Conventional dual-cure versus self-adhesive resin cements in dentin bond integrity
During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. OBJECTIVE: this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) an

12. 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
