• Radiopacity of Dental Materials.

抄録

Radiopacity of prosthetic dental materials especially used in the coronal area was determined, and the values were compared with those of enamel and dentin. Radiographs of the 2 mm thick specimens were taken together with tooth slices on aluminum step wedges. Radiographic density of the specimens were measured by means of a densitometer and expressed in terms of the equivalent thickness of aluminum. The results showed that the materials containing metal oxide and metallic compound exhibited high radiopacity values, whereas polymer-based materials with low filler content showed very low radiopacity values. A radiopacity value greater than enamel may be desirable for detection of materials or for their distinction from the tooth structure on the dental radiograph.
