“…According to Hiraishi et al 3 , through the microscopic observation of the treated dentin surface and the measurement of its permeability, it is possible to establish that the ED primer 2.0 is able to provide a moderate demineralization with dissolution of the layer and smear plugs. In 2007, Al-Assaf et al 11 showed that the extent of demineralization provided by this material is 51.99% of the dentin and the thickness of the hybrid layer is 0,95μm.…”

“…The free radical polymerization can be initiated by exposure to visible light or redox mechanism. There is also an acid-base reaction between the metal ions of the non-silanized glass particles fluorine aluminum silicate and the phosphate radical of methacrylate generated by the water produced during the neutralization reaction of the phosphate monomer, that is important for its long-term stability regarding bond strength to dentin 11 .…”

ObjectiveThe aim of this study was to evaluate, in vitro, the union stability of resin cements to the dental substract through microtensile bond strength (µTBS) analysis and scanning electron microscopy (SEM). G6 = 11.01 (A) and after 1 year: G1 = 9.75 (A), G2 = 11.73 (A); G3 = 20.10 (B); G5 = 6.80 (A); G6 = 21.09 (B). All G4 group presented pretest failures. Methods Fifty /Kuraray without pre-treatment and G6-Multilink Sprint/Ivoclar-Vivadent which were adhered to its respective indirect resin composite restoration, (G1-Clearfil AP-X/Kuraray; G2-Filtek Z350/3M ESPE; G3-Gradia Direct X™/GC; G4-Aelite™/ Bisco; G5-Clearfil AP-X/ Kuraray; G6-Tetric Ceram/ Ivoclar-Vivadent). The resin blocks were cemented and the sticks were obtained by tooth, with an area of adhesive interface of 0,8mm² (±0,2). Results The mean values, submitted to Mann-Whitney and Kruskal-Wallis tests (α = 5%) were in MPa after 24 hours: G1 = 9.66 (A), G2 = 13.37 (A); G3 = 15.89 (A); G5 = 4.18 (B); ConclusionDuring the one year period, with the exception of BisCem, the self-adhesive resin cements were a favorable alternative for the adhesive cementation, standing out among these, the G-Cem and Multilink Sprint.

“…2,3,[5][6][7][8][9] The acidic monomers bond to the hydroxyapatite (calcium) of the smear layer, dentin or enamel, creating a link between the ionized phosphoric acid and the network material. 10 On the other hand, self-adhesive cements were unable to demineralize/dissolve the smear layer completely; no decalcification/infiltration of dentin and no hybrid layer and/or resin tag formation was detectable at the bonded interfaces. 11 Many studies have evaluated the performance of immediate dentin bond strength resin cements.…”

The purpose of this study was to evaluate the effects of long-term storage on the microtensile bond strength (µTBS) to dentin of two self-adhesive and three multi-step resin cements. Two self-adhesive cements RelyX U100 (U100) and seT PP (SET), and 3 multi-step resin cements, one using 2-step etch-and-rinse adhesive AllCem (ALC), and two conventional resin cements with self-etching primer Panavia F (PAN) and Multilink (MULT) were used. Human molars were restored (n=5), sectioned and subjected to the μTBS test after 24 h and 6 months. Fractured specimens were examined by stereomicroscope and SEM. The µTBS were analyzed by one-way ANOVA and Tukey test (α=0.05). ANOVA revealed a difference between groups (p<0.0001). All multi-step resin cements ALC, MULT and PAN showed statistically similar bond strength values that were higher than those of the U100 and SET groups. The bond strength value of ALC, MULT and PAN decreases significantly after 6 months. The majority of the failures were adhesive for all the groups. The µTBS produced by the self-adhesive cements were significantly lower than those observed for multi-step luting agents. Regardless of the numbers of steps of resin cements, the storage time reduces µTBS values to dentin only to multi-step luting agents.

“…Two groups of adhesive resin cements widely used consist of a multiple-step technique and self-adhesive dual-cured luting agent, with significant difference in pre-treatment the of root canal 15 . A multiple-step technique is more sensitive and needs more clinical time; whereas, self-adhesive dual-cured luting agents require no pre-treatment 16 , and the bonding process between tooth and fiber post consists of a chemical reaction between phosphate methacrylates and hydroxyapatite 17 .…”

ResumoIntrodução: O correto uso de pinos de fibra de vidro em dentes tratados endodonticamente é essencial para o sucesso clínico do tratamento restaurador. Objetivo: Esse estudo avaliou a resistência ao cisalhamento por extrusão (push-out) em pinos de fibra de vidro reembasados (R) ou não reembasados (NR), cimentados com cimento resinoso auto-adesivo [RelyX TM U100 (U100)] e cimento resinoso convencional [RelyX TM ARC (ARC)]. Material e método: Sessenta dentes humanos unirradiculares foram tratados endodonticamente e divididos nos grupos ARC-NR; U100-NR; ARC-R; U100-R. Os dentes foram seccionados nos terços cervical, médio e apical para serem submetidos ao teste de cisalhamento por extrusão (push-out). A resistência de união foi analisada pelo teste de Friedman; os tipos de cimento e de pinos foram comparados pelo teste de Mann Whitney. O padrão de falhas foi avaliado com câmera digital através de imagens em 200x de ampliação e foi classificado como falhas adesivas (na interface cimento/dentina ou cimento/pino), coesivas (cimento ou pino), e mistas. Resultado: No grupo ARC-NR, os valores de resistência de união foram maiores no terço cervical; os grupos U100-NR e ARC-R foram semelhantes entre os terços. No grupo U100-R, os valores de resistência de união foram semelhantes nos terços cervical e médio, e houve menor valor no terço apical. Para pinos de fibra de vidro não reembasados, a média mais alta dos valores de resistência de união foi com cimento resinoso auto-adesivo. Considera-se ainda que os pinos reembasados com cimento resinoso convencional tiveram camada de cimento mais forte em comparação com os pinos de fibra não reembasados. Conclusão: A técnica do pino reembasado foi eficiente no grupo ARC-R. Os grupos ARC-NR e U100-R mostraram melhor resistência de união na região cervical das paredes do canal radicular. As principais falhas foram adesivas na interface cimento-pino.Descritores: Colagem dentária; materiais dentários; dentina; técnica para retentor intrarradicular; resistência ao cisalhamento. AbstractIntroduction: The correct use of glass fiber posts in endodontically treated teeth is essential for the clinical success of restorative treatment. Objective: This study evaluated the push-out shear bond strength of relined (R) or non-relined (NR) glass fiber posts, cemented with self-adhesive resin cement [RelyX TM U100 (U100)] and conventional resin cement [RelyX TM ARC (ARC)]. Material and method: Sixty human single-rooted teeth were endodontically treated and divided into ARC-NR; U100-NR; ARC-R; U100-R groups. The teeth were sectioned into cervical, middle and apical thirds, and subjected to the push-out test. Bond strength was analyzed by the Friedman test; cement and post types were compared by the Mann Whitney test. The pattern of failures was evaluated with digital camera through images at 200x magnification, and was classified as adhesive (at the cement/dentin or cement/post interface), cohesive (cement or post), and mixed failures. Result: In ARC-NR, bond strength values were higher in the ce...
