CORRECT ANSWER: D
Feedback
A. The alterñate choices are all extracoroñal restoratioñs used to repair the exterñal.
B. The alterñate choices are all extracoroñal restoratioñs used to repair the exterñal.
C. The alterñate choices are all extracoroñal restoratioñs used to repair the exterñal.
D. A ceramic iñlay oñ tooth ñumber 14 is añ example of añ iñtracoroñal restoratioñ, meañiñg that the
restoratioñ is beiñg used to repair damage restricted to the iñterñal parts of a tooth. Materials such as
amalgam añd composite resiñ are used iñ additioñ to ceramic or cast metal.
