“…Recently, bonding interfaces that uses selfadhesive resin cement expressed promising bond results (Bitter et al, 2014;Mohammadi et al, 2013). Resin-based cement appears to have low shrinkage, leading to a better intimate contact of the resin cement with the root canal walls (Aleisa et al, 2013;Goes et al, 2013).…”

“…The achievement of reliable bonding of posts to root canal dentin is still a challenge (Aleisa, Al-Dwairi, Alghabban, & Goodacre, 2013;Bitter, Gläser, Neumann, Blunck, & Frankenberger, 2014;Oliveira, Ramalho, Ogliari, & Moraes, 2011). The weak link of this bonding is at the dentin/resin-based cement interface after luting a fiber posts to root canal (Bitter, Paris, Mueller, Neumann, & Kielbassa, 2009;Goes et al, 2013;Mohammadi et al, 2013;Zhang et al, 2008).…”

This study evaluated the effect of Er,Cr:YSGG laser on the root canal dentin after luting a fiber post. Twenty-four bovine teeth roots were prepared using NiTi instruments and filled with Sealer 26 and gutta-percha. Post spaces were prepared and roots were distributed according to dentin treatment (n = 8): 2.5%NaOCl (group control), Er,Cr:YSGG laser (1.5 W, 20 Hz, 20 s) (group test 1) or 2.5%NaOCl + Er,Cr:YSGG laser (group test 2). Fiber posts were luted using adhesive cement (Rely X U200, 3M) and roots were prepared to confocal laser scanning microscopy (CLSM) and scanning electron microscope (SEM). The morphology of interface, thickness of cement, and the gaps and tags were analyzed. Non-parametrical data for thickness of cement were submitted to Friedman and Kruskall-Wallis tests (α = 0.05) and parametrical data for gaps to ANOVA (α = 0.05). CLSM of the cement thickness and gaps revealed no significant difference in surface treatment (NaOCl, Er,Cr:YSGG laser and NaOCl + Er,Cr:YSGG laser) (p > .05) and canal thirds (cervical, middle, and apical) (p > 0.05). SEM showed tags and a residual layer of cement adhered to dentin, mainly in laser-irradiated specimens. The pretreatment of root canal with Er,Cr:YSGG laser previously to luting the fiber post with a self-adhesive cement did not influence the cement thickness and gaps but affected the dentin interaction.

“…Conventional resin cements, in association with etch-and-rinse or self-etch adhesive systems, are typically used for luting posts. However, multiple steps application techniques are complex and sensitive, and can compromise the quality of the union, especially in the deeper areas of the root canal [2][3][4].…”

“…They do not require etching of the post space dentine or the use of adhesive systems [2][3][4]. The bond strength of self-adhesive cements appears to be superior to that of conventional cements, and does not vary according to the depth of the canal [5].…”

Objective: To evaluate the effect of two insertion techniques of self-adhesive dual resin cement on the bond strength of fiberglass posts in different portions of the root. The homogeneity of the cement layer along the root canal was also evaluated. Material and Methods: The root canals of 28 bovine teeth were instrumented, filled, and 14mm-space was prepared for luting fiberglass posts (Reforpost #3, Angelus), maintaining 4mm of apical sealing. The roots were randomly allocated into two groups according to the cement insertion technique (n=14): Lentulo Drill (Dentsply/Maillefer) or Centrix syringe (Dentsply). The posts were fixed with self-adhesive resin cement (RelyX U200, 3M ESPE). After 7 days, the roots were cross-sectioned to obtain three 1.0-mm-thick samples of each third of the space prepared for the post. Two samples of each third were subjected to push-out test (0.5 mm/min; 200N) and the third specimen was used for the analysis of cementation layer homogeneity. Images of specimens (40x magnification) were assessed and classified by two calibrated examiners (Kappa = 0.87) according to the presence or absence of voids and misfit. Data were analyzed by two-way ANOVA and Pearson Chi-Square test. Results: There was no statistically significant effect of insertion technique (p=0.278) or post-space thirds (p = 0.521) on bond strength of fiberglass posts. Chi-Square test showed that cement insertion with the Lentulo drill produced more cement voids than Centrix syringe (p = 0.023). Conclusion: The cement insertion technique did not influence bond strength of fiberglass posts in bovine root dentin. The use of Centrix syringe for cement insertion is preferred since it produced more homogenous cement layer.

“…24,25 Resin cements are reported to provide adequate post-dentin bond strength, which may be increased when self-adhesive resin cements are used. 26,27 Despite the increasing use of clear-colored and lightconductive fiber posts, few longitudinal studies of this type of restoration have been performed, particularly over the medium and long term. [19][20][21][28][29][30] Ferrari et al 19 analyzed different types of carbon and quartz fiber posts and demonstrated a low failure rate of 3.2% at 6 years, with no failures due to root fracture.…”
