following materials varies the MOST?
A. Amalgam
B. Soft tissue
C. Composite
D. Acrylic
E. Gold
The correct answer is C. Composite.
The radiographic density of composites
varies the most because the manufacturers
may place a different amount of barium
salts or other opaque filling materials.
Metals like amalgam and gold appear with
a standard amount of radiopacity.
Acrylic typically does not possess any
opaquers, and therefore is usually totally
radiolucent.
Soft tissue is fairly radiolucent.
