6.2 Shrinkage
Volumetric shrinkage (%)
Pre- and post-curing composite resin densities were measured and the polymerization shrinkage
calculated accordingly

Shrinkage stress
Figure 28: Shrinkage stress test with universal testing machine
the sample was light-cured for 40 seconds from the underside using a G-light 11mm fiber rod,
then light-cured for 20 seconds from above. the setting shrinkage stress was measured for 20
minutes and the highest figure reached was recorded as the shrinkage stress.

the volumetric shrinkage was measured
following iSO Draft Date: 2007-07-10
(Dentistry - Polymerization shrinkage of
filling materials) specifications.
this study demonstrated that
the volumetric shrinkage of
G-ænial is within the average
of the tested composites.
