title: Radiography in endodontics.
abstract: In endodontics, the paralleling technique has a geometrical advantage over the bisecting angle technique and results in radiographs with less distortion. Distortion is undesirable for endodontic radiography as it can significantly alter the apparent position of an endodontic instrument relative to the root apex. However, there are instances where the bisecting angle is preferable, and consideration should be given to this technique to improve the image quality when it is used.
