The resultant film provides an image of the whole length of the tooth and surrounding bone.In a substantial number of cases, a periapical radiograph is used to visualize only one tooth, with a large area of the film being unnecessary. Importance of Radiography in Endodontics .
Cases referred to endodontic surgery for the first time and cases referred to repeated endodontic surgery were joined in one sample. If the file is seen trespassing the apex by more than two millimeters, a new radiograph with an adjusted measurement should be taken before proceeding with canal enlargement.An angulated radiograph can be taken if more than one canal per root is suspected (Clark technique).

1995 jul 8; 179(1):35-6. Endodontics: Principles And Practice Edition 4, Illustrated Elsevier Health Sciences, 20092. Initially, a nonsurgical root canal treatment on tooth No. On periapical radiographs, roots are often superimposed upon one another and require separation for proper identification. Review.11.
Radiographic bone loss is not evident until there is significant erosion of the cortical plateClinicians must be trained to radiographically identify normal anatomical landmarks as well as anatomical variations that can mimic pathosis and to be aware that considerable distortion of radiographic images can occur when irradiation geometry is not idealAs previously stated, it may be necessary to take more than one radiograph in order to obtain maximum diagnostic information. With careful positioning of the (narrower) film and thoughtful beam angulation the first image is exposed, the film is then turned so that the unexposed side is adjacent to the tooth and a second exposure taken at a different angulation. 2007 oct; 40(10):818-30.
On many occasions, and particularly when using the bisecting angle technique, superimposition of the zygomatic process of the maxilla over the root apices of molar teeth occurs, resulting in the characteristic arch-like radiopacity which hinders radiographic interpretation.
In addition when using the bisecting angle technique the vertical orientation of the receptor is dictated by the local anatomy. This final radiograph will be the one that the clinician uses to assess healing during follow up appointments.The same principles used for diagnostic and postoperative radiographs apply to recall radiographs. In general, the degree of horizontal angulation change necessary to achieve a clear image will depend on the separation of the roots; the more parallel the roots (closer), the greater the alteration should be, whilst roots with a considerable divergence will require only a modest degree of horizontal angulation modification.The three roots of a maxillary molar are normally visible on the standard view. PARMA G (1956) Röntgenographie in der zähne und der keifer.
Radiographs provide a lasting chronicle of endodontic successes and failures. 1961.5. Radiographs are important for the dentist to identify structures harbouring disease, as well as during the progression of the treatment, as these are not visible to the naked eye.
