Internal adaptation of resin composites at two configurations: Influence of polymerization shrinkage and stress

Highlights • Internal adaptation in a high C-factor cavity was inferior to that in a low C-factor cavity for both conventional and bulk-filled composites. • Internal adaptation, polymerization shrinkage, and stress were different among composite resin materials. • Polymerization stress under the com...

Description
Summary:Highlights • Internal adaptation in a high C-factor cavity was inferior to that in a low C-factor cavity for both conventional and bulk-filled composites. • Internal adaptation, polymerization shrinkage, and stress were different among composite resin materials. • Polymerization stress under the compliance-allowed condition showed significant correlations with internal adaptations in high and low C-factor cavities. • Polymerization stress under the zero-compliance condition did not show a significant correlation with internal adaptation in the low C-factor cavity.
