A vertical, zero-degree angulation is used for exposure of which occlusal radiograph?
a. Maxillary posterior topographical
b. Mandibular anterior topographical
c. Mandibular posterior topographical
d. Mandibular cross-sectional
d. The patient's head position is such that the occlusal plane is perpendicular to the plane of the floor when exposing a mandibular cross-sectional radiograph. In other words, the patient should be reclined and the chin tipped upward. In this position, the vertical angulation will most likely be set at 0 degrees, allowing the x-rays to strike the image receptor perpendicularly.
