[Methods of roentgenologic study comprehension for appreciation of root canal obturation quality].

Comparison of methods comprehension was done with intraoral roentgenography, orthopantomography (OPG), cone-beam computer tomography (CBCT) on the devices with optical amplifier of roentgenologic image (OARI) and sensor resolution (SR) 2 pair of lines per mm and without OARI with SR 2.5 pair of lines per mm. There were used extracted earlier teeth with adequate root canal obturation.

[Planning and performing surgical stage of dental implantation in difficult clinical cases based on computer modeling].

Clinical experience of preoperative computer modeling of dental implant intervention is described. By studying the ergonomics and the accuracy a proper stereolithography guide is selected. This method allows performing a complex preoperative virtual study of dental implants placement depending on future prosthodontics restoration in difficult clinical cases.

[Endodontic treatment quality analysis according to the computer tomography data].

Endodontic treatment quality of different teeth groups was analysed according to computer tomography data. 1000 dental root canals of 521 teeth of 115 patients of different age groups were studied. The study results testified to low level of endodontic treatment quality.

[Perfection of dental root canals X-Ray study (lab-clinical study)].

Results of the study testified to the fact that on intraoral X-Ray pictures and orthopantomograms the structure of root canals of all teeth groups were not reflected objectively. The errors of methodical techniques led to considerable loss of their diagnostic comprehension. Conus computer tomography (CCTG) in comparison with spiral computer tomography was more informative and significant method for topographic study of root canals of different teeth groups determinant lower doses of patient's irradiation.

[X-ray manifestations of maxillary cavitary masses].

The paper deals with the X-ray manifestations of different maxillary pathological processes accompanied by the cavitary symptom. Analysis of X-ray films of different types in 250 patients has indicated that the nature of cavitary mass can be determined in many cases.
