“…The solution reacts with the calcium ions in dentin and forms water soluble calcium chelates. 24 Irrigation using EDTA increased the push-out bond strength when BisCem was used, but reduced the retention of posts luted with Unicem. The distinct results observed for these two materials may be related to their distinct viscosity and, as a consequence, different bonding mechanisms.…”

The aim of this study was to evaluate the effect of treating intraradicular dentin with irrigating solutions on the retention of glassfiber posts luted with self-adhesive resin cement. Bovine incisors were endodontically treated, and 9-mm-deep postholes were prepared. Before inserting the cement, the root canals were irrigated with various solutions: 11.5% polyacrylic acid for 30 s, 17% EDTA for 60 s, or 5% NaOCl for 60 s, respectively. Irrigation with distilled water was used in the control group. After all specimens had been rinsed with distilled water, the excess moisture was removed and the posts were luted using either BisCem (Bisco) or RelyX Unicem clicker (3M ESPE). Seven days after luting, the specimens were sectioned transversally into 1-mm-thick slices, which were submitted to push-out testing on a mechanical testing machine. Bond strength data (n = 6 per group) were analyzed by twoway ANOVA and Student-Newman-Keuls' test (α = 0.05). For Unicem, EDTA showed lower bond strength than the other solutions, which had similar results. For BisCem, EDTA showed higher bond strength than the other treatments, while application of NaOCl yielded higher bond strength than polyacrylic acid whereas the control group had intermediate results. In conclusion, irrigating root canals before insertion of selfadhesive resin cements, especially EDTA, might interfere with retention of the fiber posts.

“…19 However, this combined irrigation regimen can lead to erosion of the dentin surface. 20 Further, exposure of root dentin to EDTA for extended periods may decrease the modulus of elasticity and the flexure strength of dentin. 21 Such decrease may adversely affect the physical and mechanical properties of dentin, and eventually increase the risk for root fracture.…”

Effect of endodontic chelating solutions on the bond strength of endodontic sealers

et al. 2015

The purpose of this in vitro study was to evaluate the effect of various chelating solutions on the radicular push-out bond strength of calcium silicate-based and resin-based root canal sealers. Root canals of freshly-extracted single-rooted teeth (n = 80) were instrumented by using rotary instruments. The specimens were randomly divided into 4 groups according to the chelating solutions being tested: (1) 17% ethylenediaminetetraacetic acid (EDTA); (2) 9% etidronic acid; (3) 1% peracetic acid (PAA); and (4) distilled water (control). In each group, the roots were further assigned into 2 subgroups according to the sealer used: (1) an epoxy resin-based sealer (AH Plus) and (2) a calcium silicate-based sealer (iRoot SP). Four 1 mm-thick sections were obtained from the coronal aspect of each root (n = 40 slices/group). Push-out bond strength test was performed at a crosshead speed of 1 mm/min., and the bond strength data were analyzed statistically with two-way analysis of variance (ANOVA) with Bonferroni's post hoc test (p < 0.05). Failure modes were assessed quantitatively under a stereomicroscope. Irrespective of the irrigation regimens, iRoot SP exhibited significantly higher push-out bond strength values than AH Plus (p < 0.05). For both the sealers, the use of chelating solutions increased the bond strength, but to levels that were not significantly greater than their respective controls (p > 0.05). iRoot SP showed higher resistance to dislocation than AH Plus. Final irrigation with 17% EDTA, 9% Etidronic acid, and 1% PAA did not improve the bond strength of AH Plus and iRoot SP to radicular dentin.

“…A study that examined the effect of EDTA and the combination of EDTA and NaOCl on dentin in elderly and young patients showed that it is necessary to avoid prolonged exposure of old dentin to the combination of those irrigants, to reduce the risk of excessive erosion and demineralization. Both irrigants led to an increased brittleness of already sclerotic root dentin, and consequently increased the incidence of cracks during the functional loading of the root (80).…”

“…Chelating agents significantly reduce the micro hardness and pressure resistance of dentin, and this effect is most pronounced when EDTA is used as an irrigant, either alone or in combination with 2.5% NaOCl (80).…”
