Which of the following is correct regarding polymerization shrinkage of composite resin restorations?

Question

Quizplus · Accepted Answer

Recent research indicates that the composite resin material does not shrink toward the light.Chemical-cured composites cure toward the center of the bulk of the material,and light-cured materials have this tendency but are also influenced by the cavity shape and size,with minimal influence by the location of the light.When composite is placed and cured in a preparation that has two opposing walls,the shrinking composite will stress the bonds to the two walls and may end up pulling away from one of the walls.The greater the resin content of the composite,the greater is the shrinkage.Therefore microfills and flowables shrink more than hybrids.
