Elongation error results from which of the following?
A) Excessive vertical angulation using the bisecting technique
B) Excessive vertical angulation using the paralleling technique
C) Inadequate vertical angulation using the bisecting technique
D) Inadequate vertical angulation using the paralleling technique

Question

Quizplus · Accepted Answer

Inadequate vertical angulation using the bisecting technique can cause elongation error, as the image produced will appear longer than the actual tooth due to the x-ray beam being directed too shallowly. Excessive vertical angulation using either the bisecting or paralleling technique can cause foreshortening error, where the image appears shorter than the actual tooth.
