The linear shrinkage of composites was 0.33-1.41%. Shrinkage was lowest for the silorane-based (P90) composite, and highest for the flowable Z350 composite.
The new instrument was able to measure the true linear shrinkage of composites in real time without sensitivity to the specimen preparation and geometry.
Number in parenthesis is standard deviation.
Calculated volume shrinkage = 3× measured linear shrinkage.
