What is paralleling technique in dental radiography?
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..
