PERIAPICAL RADIOGRAPHIC TECHNIQUES DURING ENDODONTIC DIAGNOSIS AND TREATMENT

The objective of this article is to describe various radiographic proj ections which can be used during endodontic therapy, Changes to the an gulation of the X-ray beam in relation to the teeth and film can help diagnosis and treatment by producing images which provide additional i nformation not always visible on radiographs taken with standard angul ations. For example, changes in angulation can be useful to determine the number and curvature of roots and canals, to identify superimposed roots and to distinguish between anatomical landmarks and apical path ology. Although use of such techniques increases the diagnostic yield of films, it must be appreciated Chat such views lead to images that a re less distinct because of inherent image distortion, Nevertheless, u se of the various techniques during endodontics can provide substantia l benefit for clinicians in their daily practice.
