Influence of selective enamel etching on the bonding effectiveness of a new "all-in-one" adhesive.
OBJECTIVE
To evaluate in vitro the all-in-one adhesive G-Bond Plus/G-aenial Bond (GBP), used according to the selective enamel etching (SEE) technique, compared to Optibond FL, an etch-and-rinse adhesive tested as control (C).


METHODS
133 molars provided specimens for enamel and dentin shear bond strength (SBS) testing, microleakage measurements in class 5 restorations, and scanning electron microscope observations of demineralization patterns produced by GBP and 37% phosphoric acid (PA).


RESULTS
On enamel: C displayed the highest SBS. PA etching significantly increased enamel SBS of GBP. No statistically significant difference in SBS was noted among the bonding procedures on dentin. On both substrates, C revealed the most satisfactory seal. PA pre-etching did not significantly affect the sealing ability of GBP on either substrate.
