Correct endodontic treatments will be produced if the quality control of intra-operatory dental roentgengraphic displays an adequate periapical coverage. The degree of anatomic accuracy of Rx images depends on correct technical procedure which includes exposure, angulation, object-film and focal-film distance. According to many Authors only the paralleling extended-distance technique provides the minimum of dimensional distortion.
