Influence of water storage time on the bond strength of etch-and-rinse and self-etching adhesive systems

Abstract

The purpose of this study was to evaluate comparatively the shear bond strength (SBS) of etch-and-rinse (Adper Scotch Bond Multi Purpose--ASBMP and Adper Single Bond 2--ASB2) and self-etching (AdheSe--AD and Adper Prompt--AP) adhesive systems after short- and long-term water storage. Eighty bovine teeth were randomly assigned to 4 groups (n=20, 10 teeth for 24 h and 10 for 6 months). After surface treatment, composite resin cylinders were made with Tetric Ceram using a bisected metallic matrix. The specimens were stored in distilled water at 37 degrees C for either 24 h or 6 months. After these periods, shear strength was assessed in a universal testing machine (0.5 mm/min). Data were submitted to ANOVA and F test at 5% significance level. Mean SBSs (MPa) for ASBMP (10.03 +/- 3.78) and ASB2 (6.10 +/- 2.67) showed no statistically significant differences (p>0.05) between times. The self-etching systems did not differ significantly from each other within the 24-h period, but significant difference was found for AD (1.37 +/- 0.64) after 6 months of water storage. In conclusion, the tested etch-and-rinse systems had a better performance in terms of bond durability over time than the self-etching systems.

Dentin bond strength of two resin-ceramic computer-aided design/computer-aided manufacturing (CAD/CAM) materials and five cements after six months storage

“…Whereas the SBS of RelyX Ultimate after 24 h storage was not significantly different from the SBS of PANAVIA F2.0 or Variolink II, the SBS of RelyX Ultimate increased during storage and was significantly higher than the SBS of any other adhesive resin cement after six months. This increase in SBS is somehow in contradiction with previous studies investigating bond strength of "self-etch" adhesive systems in combination with resin composites/cements 12,13) . It may be that the storage condition applied in the present study (i.e.…”

Effect of Type of Surface Treatment and Adhesive System on Shear Bond Strength of Composite Resin to a Non-Precious Metal Alloy

“…The current study assessed the micro-shear bond strength of four adhesive systems for intraoral repair of metal-ceramic restorations with two surface treatment methods to enhance the bond of composite to non-precious metal alloy. No significant difference was observed among the [13,14]. In our study, combination of sandblasting and Z-Prime Plus was much more effective than alloy primer and Monobond Plus.…”

Dentin-composite bond strength measurement using the Brazilian disk test

“…Overall, however, results remain contradictory. For example, Dantas et al (27) found the shear bond strength of two total-etch systems (Single Bond 2 and Multipurpose) to be significantly higher than that of two self-etching systems after 24 hours of water storage. Similar results were found by Mcleod et al (28) when evaluating the influence of the C-factor on shear bond strength.…”
