Fermit had significantly less polymerization shrinkage than the other resin-based temporary filling materials. Fermit (0.22 %) < Spacer (0.38 %) < Quicks (0.64 %), Provifil (0.67 %), Clip (0.67 %)
Resin-based temporary filling materials showed 0.43 - 1.1 % expansion in 7 days.
Fermit showed the greatest leakage, while Quicks exhibited the least leakage.
There are no correlation between polymerization shrinkage or hygroscopic expansion and microleakage of resin-based temporary filling materials.
