The purpose of this study was to use shear bond strength (SBS) and shear fatigue strength (SFS) testing to determine the influence on dentin bonding of phosphoric acid pre-etching times before the application of self-etch adhesives. Two single-step self-etch universal adhesives [Prime & Bond Elect (EL) and Scotchbond Universal (SU)], a conventional single-step self-etch adhesive [G-aenial Bond (GB)], and a two-step self-etch adhesive [OptiBond XTR (OX)] were used. The SBS and SFS values were…

The influence of different etching modes and etching time periods on micro-shear bond strength of multi-mode universal adhesives on dentin
TLDR
Analysis concluded that phosphoric-acid etching for time periods greater than 5 s significantly reduced the efficacy of bonds when using multi-mode universal adhesives.
Comparison of dentin bond durability of a universal adhesive and two etch-and-rinse adhesive systems
TLDR
Although SB showed relatively stable dentin bond performance under all degradation conditions, SM showed decreased dentin SBS with prolonged degradation, whereas SU did not show any significant decrease in SBS from the baseline under any degradation condition.
Effect of Active Application on Bond Durability of Universal Adhesives.
TLDR
Active application is effective in enhancing the dentin bond durability of universal adhesives with different etching modes and practitioners should select the optimal etching mode and appropriate application method in accordance with the cavity conditions.

Bond strength and adhesive interfacial micromorphology of self-adhesive resin cements: Effect of reduced times of pre-etching
TLDR
Interfacial bond strength and adaptation of SA cements used in this study were improved following addition of enamel/dentin etching step for a short time and this was not exceeded for longer times than 5-second.

TLDR
An etching step prior to the application of the universal adhesives didn’t significantly affect their micro shear bond strength, except for Single bond universal.
The effect of Er:YAG laser irradiation on the bond stability of self-etch adhesives at different dentin depths
TLDR
The effect of laser irradiation on the bond strength of self-etch adhesives may be altered by the dentin depth, as regardless of the applied surface treatment, deep dentin showed significant bond degradation.

TLDR
The data suggest that phosphoric acid pre-etching of ground enamel improves the bonding performance of single-step self-etch adhesives, but these bonding properties do not increase for phosphoric acids pre-etched times over 3 seconds.
Effect of enamel etching time on roughness and bond strength.
TLDR
The current study examined the effect of different enamel conditioning times on surface roughness and bond strength using an etch-and-rinse system and four self-etch adhesives to determine Ra and SBS values, which were significantly greater than all theSelf-etch systems and controls.
Effect of a functional monomer (MDP) on the enamel bond durability of single-step self-etch adhesives.
TLDR
MDP might play an important role in enhancing not only bond strength but also bond durability with respect to repeated subcritical loading after long-term water storage through integrating fatigue testing and long- term water storage.
