the shear bond strength to dentine increased after thermocycling for G-ænial Bond and decreased
for all the hema containing adhesives.
it is hypothesized that the presence of hema in the composition leads to water sorption and
degradation of the bonding layer during thermocycling. Thanks to its HEMA-free composition,
G-ænial Bond is expected to provide a long-term, durable bond both and dentine and
