14. Light curing resin cements containing iodonium salts promote suitable apical bonding of posts to radicular dentin
Abstract The aim of this study was to analyze the efficiency of experimental light-curing resin cements (ERCs) with a ternary photo-initiator system containing diphenyliodonium hexafluorphosphate (DPI) and different amines on retention of glass-fiber posts to dentin (GFP). ERCs formulations: a 1:1 mass ratio of 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phen

16. The effect of hydrofluoric acid and resin cement formulation on the bond strength to lithium disilicate ceramic
Abstract To investigate how the hydrofluoric acid (HF) concentrations applied to a lithium disilicate glass-ceramic (EMX) affects the surface morphology and microtensile bond strength (μTBS) of ceramics to dentin, using light-cured resin cements with or without UDMA. Sixty-three EMX square ceramic blocks were etched for 20 seconds using different HF concent

17. Effect of Dentin Preparation Mode on the Bond Strength Between Human Dentin and Different Resin Cements
Resumo O objetivo deste estudo foi avaliar a influência de diferentes modos de preparação da dentina nas características da smear layer (SL), da camada híbrida (CH) e na resistência de união à microtração (RUµT) à dentina com dois cimentos resinosos. A dentina oclusal de 120 terceiros molares humanos foi exposta. Os dentes foram divididos em 4 gr

18. Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review
Abstract The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review invo

19. Push-out bond strength of different tricalcium silicate-based filling materials to root dentin
Abstract: The aim of this study was to evaluate the bond strength of different triccalcium silicate cements to retrograde cavity using a push out test. Thirty maxillary central incisors were shaped using #80 hand files and sectioned transversally. Root slices were obtained from the apical 4 mm after eliminating the apical extremity. The specimens were embedd

20. Evaluation of long-term bond strength and selected properties of self-adhesive resin cements
Abstract This study evaluated the shear bond strength (SBS) of self-adhesive resin cements (SARCs) to dentin and their physical-chemical properties. Five commercial SARCs were evaluated [SmartCem®2 – DENTSPLY (SC2); BisCem® – Bisco (BC); SeT PP® − SDI (SeT); Relyx U100® – 3M ESPE (U100) and YCEM® SA - Yller (YCEM)]. The SARCs were evaluated for

21. Influence of Photoinitiator on Accelerated Artificial Aging and Bond Strength of Experimental Resin Cements
Resumo O objetivo deste estudo foi avaliar in vitro o efeito do fotoiniciador fenilpropanodiona (PPD), isoladamente ou em associação com a CQ, sobre a estabilidade de cor de cimentos resinosos fotoativados e sua resistência de união adesiva à cerâmica, por teste de microcisalhamento. Foram utilizados 4 cimentos resinosos, sendo um comercial (RelyX Vene

22. 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

23. 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

24. Evaluation in vivo of biocompatibility of differents resin-modified cements for bonding orthodontic bands
ABSTRACT The focus of this study was to test the hypothesis that there would be no difference between the biocompatibility of resin-modified glass ionomer cements. Sixty male Wistar rats were selected and divided into four groups: Control Group; Crosslink Group; RMO Group and Transbond Group. The materials were inserted into rat subcutaneous tissue. After ti
