4.2 Why self-etching on dentine?
Etching of dentine does not give any additional benefit for bond strength, as demonstrated
by the independent studies below.
• Microtensile bond strength tested by Professor B. van Meerbeek at the KUL, Leuven, Belgium

leuven, Belgium, 2010
the results of this test show that there is no statistical difference in the microtensile bond strength
to dentin whether using G-ænial Bond in the self etch or in the etch-and-rinse mode.
• Shear Bond strength tests with both self-etch and etch-and-rinse techniques by Professor M.
Degrange† at the university of Paris Descartes, France

no statistical differences were found between the two techniques (self-etch and etch-and-rinse)
when using G-ænial Bond.
In conclusion, the results of these two studies prove that there is no added value in etching
dentine when using G-ænial Bond.
