Background: Dental composite resins - reinforced polymers - are types of synthetic resins that are used in dentistry as restorative material or adhesives. The effect of curing-light intensity on free volume sizes of 4 commercial dental composites has been studied by means of the well-known positron annihilation lifetime spectroscopy technique.
Objectives: The aim of the study was to compare the photosensitivity of 4 commercial dimethacrylate-based dental composites.
