“…24 PAA solution contains and liberates acetic acid, which is a weak chelating agent, but can reduce the smear layer as effective as EDTA. 23 The results of this study necessitates rejection of the null hypothesis, because the debonding values obtained after PAA treatment were statistically similar to those of EDTA-treated specimens.…”

“…22 Hence, the use of alternative chelating solutions with less or no detrimental effect on root dentin would be most desirable. 23 Among several decalcifying agents available, PAA appears to be a potential alternative to EDTA to dissolve the smear layer and disinfect the root canal system. 23,24 A previous study has shown that 1% PAA had similar effect against Enterococcus faecalis compared with NaOCl and chlorhexidine.…”

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.

“…An antimicrobial effect and a modification or dissolution of the smear layer is desired. The application of chlorhexidine or sodium hypochlorite to prepared dentin surfaces has been suggested for this purpose [10]; however previous results have shown that these solutions are not capable of completely removing the smear layer present after cavity preparation [11,12]. Furthermore, these solutions may be less than ideal in combination with adhesive techniques because of their hampering effect on bond strength [13][14][15].…”

“…Furthermore, these solutions may be less than ideal in combination with adhesive techniques because of their hampering effect on bond strength [13][14][15]. To ensure bacterial elimination in dentinal tubules, the smear layer must be removed by a strong chelator or an acid [11]. Treating dentin and enamel with acid or acid-containing liquids is widely used for routine bonding procedures.…”

Influence of dentin and enamel pretreatment with acidic sulfur compounds on adhesive performance

Objective: This study tested the potential hampering effects of acidic sulfur compounds (ASC) containing hydroxybenzene sulfonic acid, hydroxymethoxybenzene sulfonic acid and sulfuric acid, prior to self-etch and etchand-rinse bonding procedures on enamel and dentin. According to the manufacturer, ASC should be applied after cavity preparation and prior to application of a primer in order to reduce the remaining biofilm in the preparation cavity. Despite promoted marketing, data on the investigated liquid are almost completely lacking. Material and Methods: One-hundred-and-fifty-two extracted mandibular bovine incisors were embedded and polished to expose either enamel (E) or dentin (D). Then, specimenswere randomly divided and conditioned as follows (n=12/group): ASC and consecutive phosphoric acid application (E1/D1), ASC (E2/D2; E5/D5), phosphoric acid (E3/D3) and no conditioning (E4/D4; E6/D6). Groups were then treated with either Optibond FL® (etch-and-rinse; 1-4) or Clearfil SE Bond® (self-etch; 5-6).Hollow acrylic cylinders were bonded with a hybrid composite resin (Filtek Supreme XTE®) to the specimens and the shear bond strength was measured (1mm/min). In addition, failure types were assessed. Descriptive statistics and statistical analyses were performed with one-way ANOVA followed by the Scheffé post-hoc test. Results:For enamel, the highest shear bond strengths values were obtained applying routine bonding procedures (23.5 ± 5.6 MPa for etch-and-rinse and 26.0 ± 6.0 MPa for selfetch respectively). In contrast, dentin pre-treatment with a combination of ASC and phosphoric acid led to the highest shear-bond values (22.8 ± 4.1 MPa). Conclusion:This study shows that ASC prior to dental restoration placement cannot be recommended for etch-and-rinse procedures on enamel, but is appropriate for dentin without interfering with routine bonding procedures. Clinical Relevance:The application of acidic sulfur compounds prior to adhesive restoration placement should be restricted to dentin only as it may negatively influence shear bond strength on sound enamel.

Effects of ethylenediaminetetraacetic, etidronic and peracetic acid irrigation on human root dentine and the smear layer

Abstract: The decalcifying agents under investigation were all able to remove or prevent a smear layer. However, they eroded the dentine wall differently.
