1. Rely XTM U200 versus Rely XTM ARC: uma comparação da resistência à microtração
Resumo Introdução Os cimentos resinosos são extensivamente utilizados na fixação de restaurações indiretas de cerâmica e cerômero, sendo classificados em duas categorias: os cimentos resinosos convencionais, que não apresentam uma adesão inerente à estrutura dental e requerem o uso de um sistema adesivo e os cimentos resinosos autoadesivos, que

2. Microtensile bond strength of CAD/CAM materials to dentin under different adhesive strategies
Abstract: The present study aimed to evaluate the microtensile bond strength (μTBS) of novel computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials to dentin using different adhesive strategies. Thirty-two crowns were milled using CAD/CAM materials (Vita Mark II as control, Vita Suprinity, Vita Enamic and Lava Ultimate) and luted

3. Correlation between clinical performance and degree of conversion of resin cements: a literature review
AbstractResin-based cements have been frequently employed in clinical practice to lute indirect restorations. However, there are numerous factors that may compromise the clinical performance of those cements. The aim of this literature review is to present and discuss some of the clinical factors that may affect the performance of current resin-based luting

4. Effects of coronal substrates and water storage on the microhardness of a resin cement used for luting ceramic crowns
Composite resin and metallic posts are the materials most employed for reconstruction of teeth presenting partial or total destruction of crowns. Resin-based cements have been widely used for cementation of ceramic crowns. The success of cementation depends on the achievement of adequate cement curing. Objectives: To evaluate the microhardness of Variolink

5. Influence of Er,Cr: YSGG laser on bond strength of self-adhesive resin cement
The purpose of this study was to investigate the bond strength of fiber post previously laser treated root canals. Forty single-rooted bovine teeth were endodontically treated, randomly and equally divided into two main groups according to the type of pretreatment: G1: 2.5% NaOCl (control group); and G2: Er,Cr:YSGG laser. Each group was further subdivided in

6. 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

7. Effect of reduced exposure times on the cytotoxicity of resin luting cements cured by high-power led
OBJECTIVE: Applications of resin luting agents and high-power light-emitting diodes (LED) light-curing units (LCUs) have increased considerably over the last few years. However, it is not clear whether the effect of reduced exposure time on cytotoxicity of such products have adequate biocompatibility to meet clinical success. This study aimed at assessing th

9. Dureza Knoop e resistência da união de cimentos resinosos após a fixação de pinos de fibra em diferentes condições técnicas e regiões da raiz / Knoop hardness and bond strength of resin cements after fixing fiber posts in different technical conditions and regions of root
The objective of this study was to evaluate the bond strength through the push-out test and Knoop microhardness of resin cements after fixation of fiber posts, in the manners conventional, with a flared root and with composite resin relined post, according to root area. From the 60 bovine incisor roots, forty were weakened with diamond bur #4137, and all wer

10. A critical analysis of the degree of conversion of resin-based luting cements
OBJECTIVE: This study analyzed the degree of conversion (DC%) of four resin-based cements (All Ceram, Enforce, Rely X ARC and Variolink II) activated by two modes (chemical and dual), and evaluated the decrease of DC% in the dual mode promoted by the interposition of a 2.0-mm-thick IPS Empress 2 disc. MATERIAL AND METHODS: In the chemical activation, the res

11. Análise da resistência de união, nanoinfiltração e características ultramorfológicas das interfaces de união resina-dentina produzidas por cimentos auto-adesivos ao longo do tempo.
This study evaluated the effects of a peripheral enamel bond on the long-term microtensile bond strength (μTBS) and nanoleakage in resin-dentin interfaces produced by self-adhesive and conventional resin cements. Five self-adhesive cements [RelyX-Unicem(UN), RelyX-U100(UC), GCem(GC), Maxcem(MC), Set(SET)] and 2 conventional resin cements, one that uses
