[en] Only two roentgenography methods (periapical and occlusion) are used for production of dental roentgenograms. Periapical survey must be used only for revealing state of bone tissue around tooth root tops. In parodontology it is necessary to use occlusion survey. Perfection of the methods and improvement of quality of tooth roentgenograpms demand to change the design of native dental X-ray unit: elongation of its tube, increase of radiator power. Introduction of orthopantomography as basis method of roengenography in stomatology is the most radical decision of methodological problems. Orthopantomography is replaced by intra- and extra-oral roentgenography of teeth and jaws
