# The image of the coronoid process of the mandible often appears in periapical x-rays of:
A. The incisor region of the mandible
B. The molar region of the mandible
C. The incisor region of the maxilla
D. The molar region of the maxilla



The correct answer is D. The molar region of the maxilla.

As the mouth is opened, the coronoid process moves forward, and therefore it comes into  view
most often when the mouth is opened to its fullest extent at the time the exposure is made.
It is evidenced by a tapered or triangular radiopacity, which may be seen below, or in some instances superimposed on the molar teeth and maxilla.

The coronoid process appears as a triangular-shaped radiopacity.
