Bisecting and Paralleling Techn. Flashcards
One of the advantages of the Bisecting Technique is:
Can be used when a patient has a shallow palate
In taking a periapical radiograph using the bisecting technique, the x-ray beam was not centered on the film packet. The resulting film shows:
Cone cut
According to the basic principles of the paralleling technique, the film is placed in the mouth____ to the long axis of the tooth being radiographed, and the central ray of the x-ray beam is directed ______ to the film long axis of the tooth.
Parallel; perpendicular
When using the Bisecting Technique what is the relationship b/w the imaginary bisector and the central ray?
The central ray is perpendicular to the imaginary bisector
A periapical film must show:
The crown and the apex of the tooth
One of the advantages of the parallel technique is:
Simple and easy to use
When the bisecting technique is used, which of the following angles is bisected?
The angle formed by the receptor and the long axis of the tooth
What factor affects forshortening and elongation of a tooth image on the film while using the Bisecting Technique?
Vertical angle
A small (short) object-receptor distance will increase magnification of the tooth image? T or F?
False
When using the Parallel Technique the film and the ____ should be as parallel as possible
long axis of the tooth
