Материал и методы. Изучены тест-объекты (фантомы), содержащие различные группы зубов, позволяющие проводить рентгенологическое исследование в одинаковом положении. Методы исследования: МСКТ, конусно-лучевая-компьютерная томография (КЛКТ), КЛКТ с высоким разрешением (ВР) и микрокомпьютерная томография. Результаты. При сравнительной оценке методов исследования индекс превышения значений микрокомпьютерной томографии составил от 2 до 16 раз, преобладая над другими рентгенологическими томографическими методиками. Методики сравнения достоверно не отличаются друг от друга в точности определения объема. Выводы. Величина превышения была наибольшей для КЛКТ, затем по величине превышения следовало сравнение с МСКТ, наименьшим превышение оказалось для КЛКТ-ВР.</p></abstract><trans-abstract xml:lang="en"><p>The aim: to study the accuracy of various radiographic tomographic techniques in the evaluation of the volume of the root canal. Materials and methods. Test objects (phantoms) containing various groups of teeth, allowing to carry out X-ray examination in the same position were studied. The research methods: multislice computed tomography, cone-beam computed tomography, cone-beam computed tomography with high resolution and microcomputer tomography. Results. The index values exceeding microcomputer tomography ranged from 2 to 16 times dominating over other radiological tomographic techniques at a comparative assessment of methods of research. Comparison methodology was not significantly different from each other in the accuracy of the determination of volume. Conclusion. The excess was greatest for CBCT, then the excess should compare with MSCT, the smallest excess proved to CBCT-HR.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>МСКТ</kwd><kwd>КЛКТ</kwd><kwd>микро-КТ</kwd><kwd>зубы</kwd><kwd>корневые каналы</kwd><kwd>MSCT</kwd><kwd>CBCT</kwd><kwd>micro-CT</kwd><kwd>teeth</kwd><kwd>root canal</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Swain M.V., Xue J.
