“…These results are in agreement with other studies that showed the highest shear bond strength values with a totaletch technique [25,26]. When applying self-etching adhesives, it was shown that additional or extended etching on sound dentin did not improve the tensile bond strength [27].…”

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.

“…Previous studies report assessments of wetting of adhered surfaces according to contact angles 23,24) , and the surface-free energy of a solid (γs) reportedly reflects dispersion (γs d ), polarity (γs p ), and hydrogen-bonding (γs h ) forces 25) . Whereas dispersion forces represent London interactions between apolar molecules, polar (non-dispersion) forces include electrostatic, metallic, and dipolar interactions.…”

(AB, Bisco) were used in this study. Bovine dentin surfaces were air polished with glycine or sodium bicarbonate powders prior to the bonding procedure, and resin pastes were bonded to the dentin surface using universal adhesives. SBSs were determined after 24-h storage in distilled water at 37°C. Surface-free energy was then determined by measuring contact angles using three test liquids on dentin surfaces. Significantly lower SBSs were observed for dentin that was air-powder polished and surface-free energies were concomitantly lowered. This study indicated that air-powder polishing influences SBSs and surface-free energies. However, glycine powder produced smaller changes in these surface parameters than sodium bicarbonate.

“…8 Etch-and-rinse adhesives require a separate step of etching, which is usually performed with 30-40% phosphoric acid. 25,26 In etch-and-rinse adhesive systems, the quality of the created bond is greatly influenced by the duration of the etching process and by the amount of dentin surface moisture following rinsing of the etching acid and prior to resin infiltration. In the present study, the total-etch adhesives, XP Bond and Adper Single Bond 2, showed greater bond strengths to moist dentin when compared to the other self-etch adhesives, Adper Easy One and Xeno V. This finding is in agreement with studies conducted by Susin 27 : and Cardoso and others.…”

The bond strengths of adhesive systems are affected by the amount of moisture on the bonding surface of the tooth. SUMMARYThis study compared the tensile bond strengths of different adhesive systems to different dentinal substrate conditions. The adhesive systems used were Adper Single Bond 2 total etch, XP Bond total etch, and two all-inone adhesives, Adper Easy One and Xeno V. Ninety-six intact human premolars extracted on periodontal or orthodontic grounds were collected and stored in 0.9% physiologic saline for less than four weeks. Teeth were carefully cleaned to remove the soft tissue remnants. The occlusal surfaces were ground until the level of the dentinoenamel junction, exposing superficial dentin using a low-speed diamond disc. A standard smear layer was produced by wet sanding the dentin surface with 600-grit silicon carbide sandpaper for 40 seconds. The 96 specimens were embedded in autopolymerizing acrylic resin and divided into four groups of 24 each based on the dentin bonding agents used. Each group consisted of 24 specimens, which were further divided into two subgroups of 12 specimens each, moist dentin and dentin air-dried for 10 seconds. The regions of interest for adhesion were demarcated in each sample using adhesive tape, with a 4-mm-diameter hole isolating the peripheral region, and each adhesive system was employed. Four adhesive systems, two total etch and two self-etching adhesive, were applied to different dentinal substrates as per the manufacturers' instructions. Following the adhesive application, the specimens were restored with composite material using a metallic mold measuring 5 mm in diameter and 5 mm in height to keep the material in cylindrical form and were light cured per manufacturers' instructions. After being stored for 24 hours in distilled water at room temperature, the specimens were thermocycled for 550 cycles at temperatures ranging from 58C to 608C with a dwell Mithra N.
