13. 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

14. Influence of the interposition of ceramic spacers on the degree of conversion and the hardness of resin cements
This study evaluated: I) the effect of photo-activation through ceramics on the degree of conversion (DC) and on the Knoop hardness (KHN) of light- and dual-cured resin cements; and II) two different protocols for obtaining the spectra of uncured materials, to determine the DC of a dual-cured resin cement. Thin films of cements were photo-activated through c

15. Effects of cement-curing mode and light-curing unit on the bond durability of ceramic cemented to dentin
The aim of this study was to evaluate the effects of different light-curing units and resin cement curing types on the bond durability of a feldspathic ceramic bonded to dentin. The crowns of 40 human molars were sectioned, exposing the dentin. Forty ceramic blocks of VITA VM7 were produced according to the manufacturer's recommendations. The ceramic surface

16. Do blood contamination and haemostatic agents affect microtensile bond strength of dual cured resin cement to dentin?
Objective The purpose of this study was to evaluate the effects of blood contamination and haemostatic agents such as Ankaferd Blood Stopper (ABS) and hydrogen peroxide (H2O2) on the microtensile bond strength between dual cured resin cement-dentin interface. Material and Methods Twelve pressed lithium disilicate glass ceramics were luted to flat occlusal

17. INFLUÊNCIA DE DIFERENTES TRANSLUCIDEZ DAS CERÂMICAS SOBRE O GRAU DE CONVERSÃO E MICRODUREZA DE UM CIMENTO RESINOSO DUAL / Influence of different ceramic translucency on the degree of conversion and microhardness of dual resin cement
The proposition of this study was to evaluate the influence of different ceramic translucency on the degree of conversion and Knoop microhardness of dual resin cement. It was made 150 samples of the resin cement dual cured Variolink II (shade A3; 5 mm in diameter and 1 mm thick) were created with interposing ceramic discs with 8 mm in diameter and 1.5 mm thi

18. Influence of remaining coronal structure and finish line on the fracture strength of roots restored with metallic posts
The purpose of this study was to evaluate the fracture strength of roots that were prosthetically restored with metallic posts with or without any remaining coronal structure and with different finish lines. Sixty bovine incisors were sectioned below the cementoenamel junction, endodontically treated, and randomly divided into six experimental groups (n = 10

19. 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

20. Light-activation through indirect ceramic restorations: does the overexposure compensate for the attenuation in light intensity during resin cement polymerization?
OBJECTIVES: 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 Medic

21. 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

22. 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

23. Efeito do protocolo de ativação da polimerização e envelhecimento acelerado em algumas propriedades de cimentos resinosos / Effects of polymerization activation protocol and accelerated aging in some resin cements properties
The study aimed to evaluate the effects of curing protocol and accelerated aging on some properties of dual-cure resin cements. Additionally, the effects of different ambient temperature and aging on the working and setting times were investigated when cements were self-cured only. Properties evaluated were degree of conversion as determined by FTIR-ATR spec

24. Effect of thickness of indirect restoration and distance from the light-curing unit tip on the hardness of a dual-cured resin cement
O estudo avaliou a profundidade de polimerização de um cimento resinoso dual, através da dureza Knoop (KHN), ativado em diferentes distâncias e espessuras de compósito resinoso. A dentina bovina foi planificada e embutida em resina, coberta com filme de PVC, onde um molde (0,8 mm x 5 mm) sobreposto foi preenchido com cimento e coberto com outro filme de
