The everyday use of standard X-ray studies, such as intraoral radiography, less frequently orthopantomography, permits detailed characterization of the anatomic characteristics of dentin, which are required to plan an endodontic treatment policy for permanent teeth in adolescents and young people. The application of dental volume tomography (DVT) evidence will make it possible to objectify criteria for the level of formation of tooth root dentins and their mineralization levels, by further developing the principles of planning and endodontic treatment, which consider anatomic characteristics. The purpose of the investigation was to study the informative value of DVT during endodontic treatment for permanent teeth in adolescents and young people. One hundred and ninety-five DVT scans, 195 orthopantomograms, and 300 radio images, which were made in 159 patients aged 12 to 24 years (a study group) and 36 patients aged 25-30 years (a control group), were examined. Analyzing DVT evidence yielded the mean threshold values for an apical foramen width of 0.62 to 0.66 mm and an apical root dentin density of 1390 to 1410 units, which were characteristic of formed permanent teeth. An endodontic treatment policy was chosen according to which range the values of apical foramen widths and dentin densities were within. The study of DTV values has indicated that this technique is of more informative value than others and may be recommended for its extensive use as a first-line method. |
