Comparative Evaluation of the Effect of Radiation on the Marginal Adaptation of Different Composite Restorative Materials: An In Vitro Study.

Researchers compared how four composite restorative materials responded to therapeutic radiation by measuring marginal gaps before and after exposing restored teeth to 70 Gy. All materials showed increased marginal gaps after radiation, with ormocer performing best and bulk-fill composite performing worst.
