Failing to record the incisal or occlusal edges of the teeth on a periapical radiograph most likely results from an error made in which of the following steps?
A) Placement of the image receptor
B) Horizontal angulation
C) Vertical angulation
D) Centering the x-ray beam

Question

Quizplus · Accepted Answer

Vertical angulation is the angle between the long axis of the tooth and the plane of the image receptor. The incisal or occlusal edges of the teeth must be captured on a periapical radiograph by adjusting the vertical angulation. If the vertical angulation is incorrect, the incisal or occlusal edges may not be visible on the radiograph. Placement of the image receptor, horizontal angulation, and centering the x-ray beam are important for proper radiographic technique, but do not directly affect the visibility of the incisal or occlusal edges.
