“…The tomographic section thickness was 1 mm, the reconstruction step -1 mm, the rotation step -1 mm, the reconstruction mode was set as BONE and STDN (standard) [7,21,30,32]. The radiological density of the mandibular bone was examined based on mathematical reconstruction of the attenuation coefficients expressed in Hounsfield units (HU) [10,18,20,26,29,35]. The areas for the investigation we selected included the mandibular body at the second molar and the mandibular angle (C. Ulm, 2009).…”

This article focuses on issues related to bone tissue diagnostics in children with type I diabetes (different length of disease history). The results of densitometry with automatic calculation of the Z-criterion, allowed evaluating the bone tissue mineral density in the lumbar spine. The quantitative and qualitative specifics of the jaw bone tissue were based on orthopantomography and cone-beam computed tomography. The mineral and bone metabolism status was studied based on the laboratory-test data (total calcium, ionized calcium, phosphorus, alkaline phosphatase, calcitonin, osteocalcin, parathyroid hormone, 25 OH vitamin D, β-CrossLaps). The earlier stages of the disease were found to feature an increase in the bone tissue remodeling rate along with escalating bone formation intensity. The children with a long history of type 1 diabetes revealed slower bone remodeling with bone resorption dominating over bone formation, as well as a significant decrease in the mineral density with the bone tissue structure demonstrating the dominance of the criteria like within the expected age norm and low mineral density with respect to the average age norm. K E y w o r d s-type 1 diabetes, osteodensitometry, conebeam computed tomography, orthopantomography, bone metabolism. I n t R o D U C t I o n The results of epidemiological studies carried out by the International Diabetes Federation in more than one hundred countries all over the world in the past forty years showed that type 1 diabetes is the leading condition among endocrine pathologies in children, and the current trend points at a steady increase in the incidence. These data served the basis for adopting regulatory and legal international acts aimed at combating type 1 diabetes in children (St. Vincent

“…Currently, the orthodontic treatment planning is done reasoning from the position of the upper incisors, and not the molars or the lower jaw incisors. Given that, when planning mechanical teeth shift, some clinicians recommend placing the incisors in an ideal position to further restore the occlusal match of the remaining teeth [27][28][29][30].…”

Aim. To determine the link between the clinical and radiological torque of the medial incisors in cases with physiological occlusion. Materials and methods. A measurement of the clinical torque values was performed (whereas the torque is defined as the deviation of the tooth crown vestibular surface from the occlusal plane) in 98 people with physiological occlusion and a full set of permanent teeth. When measuring the clinical incisor torque, three methods were employed. The first method allowed studying teeth torque in relation to the occlusal plane on the cast jaw models using the ArcoZet equipment (by Scheu Dental GmbH). The second method implied using a modified protractor, where the moving part was oriented in relation to the occlusal plane. The third method we used involved analyzing data from teleradiography and cone-beam tomograms obtained with the PaX-i3D SC digital panoramic X-ray unit (VATECH Global), which were marked with linear and angular reference points. The patients were divided into three groups depending on the incisors location: Group 1 included patients with the mesotrusive incisors location; Group 2 were patients with physiological protrusion of the incisors and a decrease in the interincisal angle, with Group 3 including patients with physiological retrusion of incisors. Results. Regardless of the type of dental arches and the vestibular lingual inclination of the incisors, the average difference between the clinical and the radiological incisor torque values is 26°, which can be used in clinical orthodontics to develop a treatment tactics and its effectiveness in people with various gnathic and dental types as well as with various dental arches. Conclusion. All methods used for measuring the teeth inclination angles in the vestibular lingual direction can be employed both in the applied and in the clinical aspect. Identifying the permanent teeth torque through cast models of dentition morphometry and through using special equipment, takes a lot of effort, time, at the same time being subject to potential measurement errors. The methods implying analysis of cone-beam computed tomography images feature high-tech reliance, precision, whereas the reproductive capacity and interpretation of the results allows using the available angular and linear parameters for evaluating the effectiveness of the respective orthodontic procedures through all the stages of treatment

“…Recently, patients have been taking significantly higher interest in restoring the aesthetic and functional standards [1][2][3][4][5]. A significant technological breakthrough as well as the introduction of advanced reliable techniques in orthodontics offer us newer opportunities and prospects in diagnosing and treating dentofacial anomalies [6][7][8][9][10].…”

This work reveals the analysis outcomes for craniometric and morphometric parameters of the temporomandibular joints and incisal dentofacial segments obtained through studying 157 computer tomograms and lateral skull teleradiographies from people with physiological occlusion of permanent teeth in the first mature age period. Detailed investigation of the spatial arrangement of the craniofacial structures allowed developing, substantiating and testing a method of computer tomograms combination of the mandibular joint and dentofacial segments of the mandibular and maxillary medial incisors with head teleradiographies in the lateral projection. This algorithm allowed increasing the measurements reliability (linear, angular) in the sagittal plane, identifying the degree of complexity and justifying the choice of tactics for the planned treatment, describing the facial skull growth type (horizontal, vertical and neutral), as well as evaluating the effectiveness of orthodontic treatment at all stages.
