What was done
This is a narrative review describing the mechanisms and factors influencing polymerization shrinkage stresses in direct light-cured dental composite resins, along with their clinical consequences and strategies for management.
What was found
The abstract provides no numerical data. It reports that polymerization shrinkage generates stress within the restorative material and at the interface, causing marginal failure, staining, secondary caries, restoration displacement, tooth fracture, and postoperative sensitivity.
Why it matters
It outlines how composite polymerization stress compromises restorative margins and highlights the necessity of clinical management strategies to improve restoration longevity.
Limits
This is an unsystematic narrative overview without described search criteria, study selection methods, or statistical synthesis. The abstract contains no primary human data or comparative outcome measurements.
