Full mouth survey
All of these are the functions of film holder when taking intraoral xray EXCEPT
it facilitates aligning the xray cone with the film in both horizontal and vertical planes
increases accuracy and reduces the need for unnecessary retakes
it provides comfort to the patient
it is known as aiming ring
Choose the correct name for line A and B
A. Perpendicular line
B. Long axis of tooth

B. Imaginary bisecting line
............................... technique is used when the film cannot be placed parallel to the long axis of the tooth due to anatomical interference.
Perpendicular
Paralleling
Bisecting
Imaginary
