Excessive vertical angulation when using the paralleling technique results in
A) cutting off incisal/occlusal edges.
B) cutting off the apices.
C) foreshortened images of the teeth.
D) elongated images of the teeth.
A
Explanation: A) When the vertical angulation is excessive (greater than perpendicular to the recording plane of the image receptor), the incisal or occlusal edges of the teeth will most likely be cut off.
B) When the vertical angulation is excessive (greater than perpendicular to the recording plane of the image receptor), the incisal or occlusal edges of the teeth will most likely be cut off.
C) When the vertical angulation is excessive (greater than perpendicular to the recording plane of the image receptor), the incisal or occlusal edges of the teeth will most likely be cut off.
D) When the vertical angulation is excessive (greater than perpendicular to the recording plane of the image receptor), the incisal or occlusal edges of the teeth will most likely be cut off.
