The recommended vertical angulation for exposing a mandibular canine periapical radiograph using the bisecting technique is:
A) -10 degrees
B) -15 degrees
C) -20 degrees
D) -5 degrees

Question

Quizplus · Accepted Answer

The recommended vertical angulation for mandibular canine periapical radiographs using the bisecting technique is -20 degrees. This is due to the position of the mandibular canines being more inferior in the mouth compared to other teeth. The bisecting technique aims to provide a more accurate representation of the tooth by bisecting the angle between the tooth and the plane of the film. Therefore, a steeper vertical angle of -20 degrees is necessary to position the film closer to the tooth and reduce distortion. Choices A, B, and D are not correct as they are outside the recommended range for mandibular canines using the bisecting technique.
