The recommended vertical angulation for exposing a maxillary canine periapical radiograph using the bisecting technique is

A) +20 degrees.
B) +30 degrees.
C) +40 degrees.
D) +45 degrees.

D
Explanation: A) To obtain a radiograph with an accurate representation of the maxillary canine, the central ray of the x-ray beam should be directed toward the imaginary bisector between the long axis of the canine and the plane of the image receptor in the vertical dimension at +45 degrees.
