[The diagnostic value of oblique technique for periapical radiography and its usefulness in endodontic treatment].

The applicability of the intraoral X-rays in the oblique projection during the endodontic treatment is described in this study. The rules concerning the positioning of the X-ray tube, intraoral film and the examined tooth, necessary to obtain images in mesial and distal oblique projections are discussed. The usefulness of the aforementioned projections in visualizing the anatomy, anomalies as well as periapical changes of the dental roots and canals during the endodontic treatment is presented.
