Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The ____ technique is accomplished by placing the receptor as close to the tooth as possible. The central ray of the x-ray beam should be directed perpendicular to an imaginary line that divides the angle formed by the long axis of the tooth and the plane of the image receptor
A
Bitewing technique
B
Bisecting Angle Technique
C
paralleling technique
D
None of the above
Explanation: 

Detailed explanation-1: -The bisecting angle technique is accomplished by placing the receptor as close to the tooth as possible. The central ray of the x-ray beam should be directed perpendicular to an imaginary line that bisects or divides the angle formed by the long axis of the tooth and the plane of the image receptor.

Detailed explanation-2: -The parallel technique is defined as the parallelism between the object to be studied and the plane of the film while the central axis of the X-ray is perpendicularly adjusted to both planes. Unfortunately, it is much easier to get a perpendicular position of the X-ray central axis to the film than to the object.

Detailed explanation-3: -There are two types of techniques used for periapical radiographs: bisecting angle, and paralleling. The bisecting technique may have to be used for patients unable to accommodate the film positioning device used in the paralleling technique.

Detailed explanation-4: -Two types of exposure techniques may be used for intraoral periapical radiography: the paralleling and the bisecting angle technique (Figures 1 and 2). With the paralleling technique, the tooth and the sensor are both kept on a parallel planes.
