Radiographic images of teeth and restorations were used to evaluate the radiopacity of 11 light-cured posterior composite resins. The radiopacity of these composite resins provided enough variation on radiographs so that clinicians distinguished the images of the restoration from adjacent tooth structure.
牙齿和修复体的X光影像被用于评估11种光固化后牙复合树脂的射线不透性。这些复合树脂的射线不透性在X光片上提供了足够的差异，以便临床医生区分修复体与相邻牙齿结构的影像。
