Detailed explanation-1: -As previously discussed, the paralleling technique is the most accurate intraoral radiographic technique, meeting four of the five principles of accurate image projection. The paralleling technique does not allow for an as short as possible object-to-receptor distance (Principle Three) as desired.

Detailed explanation-2: -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.

Detailed explanation-3: -The paralleling technique is the most commonly used technique for exposing periapical and bitewing radiographs because it creates the most accurate representation of a tooth image. It refers to the receptor being positioned parallel to the full length (long axis) of the tooth being radiographed.

Detailed explanation-4: -Variables of Intraoral Imaging There are four variables involved in acquiring radiographic images: horizontal angulation, vertical angulation, sensor placement, and head position.
