“…[6][7][8] However, all alterations compromise the penetration of the bonding agents into dentin, impairing hybrid layer formation, even after acid etching. [9][10][11] Collagen removal by sodium hypochlorite 12,13 after irradiation could promote better conditions for bonding, because collagen fibrils are altered by laser irradiation, not allowing the diffusion of monomers into the demineralized intertubular dentin. The additional and extended etching time 14 could result in more dissolution of altered hydroxyapatite, enhancing the penetration of adhesive monomers.…”

“…Consequently, this technical possibility was the initial step for the establishment of esthetic restorations with improved marginal integrity and bond strength [5][6][7] . The presence of a conditioned dentin zone where occurs the polymeric infiltration has also been demonstrated in classic studies 3,8,9 and other more recent investigations has focused the importance of the polymer-dentin interdiffusion zone in the adhesive restorations with dental composites [10][11][12] . This zone is characterized by the diffusion of different adhesive systems through inter and peritubular dentin, improving the marginal sealing and the bond strength between dental polymer and tooth 3,13 .…”

This study evaluated an alternative method for thermal cycling test on the microleakage and bond strength of the polymer-dentin bond. For the microleakage test the cavities were restored with a TEGDMA+UDMA+bis-EMA composite polymer light cured for 20 s. Samples were immersed in 2% methylene blue solution for 2 h and sectioned. Microleakage scores were submitted to Kruskal-Wallis test. For the shear bond strength test the adhesive was applied to dentin, photoactivated for 10 s and the composite polymer incrementally photoactivated. Samples were submitted to shear bond strength test in a machine with a cross-head speed of 0.5 mm/min and data were submitted to ANOVA and Tukey's test. Studied groups were: 1 -without thermocycling; 2 -thermocycled at 5 °C and 55 °C with intermediate bath at 37 °C; 3 -thermocycled at 5 °C and 37 °C; 4 -thermocycled at 37 °C and 55 °C; 5 -thermocycled at 5 °C and 55 °C (traditional test). Cold baths promoted greater microleakage when compared to control and hot bath, whereas control and hot bath were similar. Cold baths presented significant lower shear bond strength than those submitted to hot bath and control. It was concluded that the alternative method for thermal cycling test showed that cold temperatures increased the microleakage and decreased the bond strength of the polymeric adhesive.

“…Luting procedures were performed in a warm room at 37°C. 20 The inlays were luted either with a self-adhesive resin cement (RelyXUnicem 2 ® Clicker, 3M ESPE) or a self-etch resin cement (Multilink ® Automix, Ivoclar-Vivadent). The luting agent used on the buccal or lingual surface was randomly chosen by draw.…”

“…[17][18][19] An established hybridization is typically observed with the use of total-etch or self-etch cements, whereas more superficial physical interactions and possible involvement of chemical reactions between the material and dental hard tissues have been found with self-adhesive cements. 13 Micromorphological analyses of adhesive interfaces, performed either between the tooth and adhesive systems [20][21][22] or between the tooth and resin cements, 23,24 have made important contributions to the correct use of adhesive materials, with the aim of improved bonding efficiency and durability. More recently, micro-Raman spectroscopy (MRS) has been used as an alternative method to the traditional morphological imaging techniques for examining the adhesive interface.…”

Abstract. This study analyzed the diffusion of two resin luting agents (resin cements) into dentin, with the aim of presenting an analytical method for estimating the thickness of the diffusion zone. Class V cavities were prepared in the buccal and lingual surfaces of molars (n ¼ 9). Indirect composite inlays were luted into the cavities with either a self-adhesive or a self-etch resin cement. The teeth were sectioned bucco-lingually and the cementdentin interface was analyzed by using micro-Raman spectroscopy (MRS) and scanning electron microscopy. Evolution of peak intensities of the Raman bands, collected from the functional groups corresponding to the resin monomer (C─O─C, 1113 cm −1 ) present in the cements, and the mineral content (P─O, 961 cm −1 ) in dentin were sigmoid shaped functions. A Boltzmann function (BF) was then fitted to the peaks encountered at 1113 cm −1 to estimate the resin cement diffusion into dentin. The BF identified a resin cement-dentin diffusion zone of 1.8 AE 0.4 μm for the self-adhesive cement and 2.5 AE 0.3 μm for the self-etch cement. This analysis allowed the authors to estimate the diffusion of the resin cements into the dentin. Fitting the MRS data to the BF contributed to and is relevant for future studies of the adhesive interface. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
