[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. According to the results of the study the image received with the help of CBCT with high SR let have the biggest information volume about filling quality of root canal and root canal structure peculiarities that testified to pro of the method over CBCT with OARI. The most widespread in the practice methods of intraoral roentgenography and orthopantomography not in all cases reflected reliably the root canal obturation degree.
