The 1998 study used to challenge the common belief that dental composites primarily shrink toward the curing light. The researchers discovered that:
: The resulting "polymerization shrinkage stress" can lead to enamel cracks, post-operative sensitivity, and gaps that allow for secondary cavities.
: Shrinkage creates complex stress fields. Paradoxically, some "incremental" filling techniques (placing material in layers) can actually increase tooth deformation compared to a single "bulk" fill. Download versluis1998 pdf

: The direction of shrinkage is actually determined more by the bonding between the composite and the tooth and the shape of the cavity rather than the position of the light.
