Detailed explanation-1: -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-2: -Which describes the relationship between the receptor and the long axis of the tooth in the paralleling technique? b. The receptor is placed away from the tooth and toward the middle of the oral cavity.
Detailed explanation-3: -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.
