Документ Optical density of mandible in orthodontic patients(Wydawnictwo Aluna, 2018) Kuroedova, V. D.; Vyzhenko, E. E.; Makarova, A. N.; Stasiuk, A. A.; Куроєдова, Віра Дмитрівна; Виженко, Євгеній Євгенович; Макарова, Олександра Миколаївна; Стасюк, Олексій АнатолійовичIntroduction: The given article is concerned with peculiarities of the change in the bone mineral density of the jaw bones in the dynamics of bone structure growth in the locomotor apparatus of orthodontic patients. The aim of the paper is to carry out a comparative analysis of the mineral density of the bone tissue of the lower jaw (mandible) and the mineral density of the second cervical vertebra (C2) in patients with malocclusion. Materials and methods: 37 computer tomograms of orthodontic patients were studied, which were divided into three age groups according to the periods of the formation of the dentoalveolar system. Measurement of bone density of (second cervical vertebra) C2 was performed in the sagittal projection along the middle of the height of the vertebra. In the mandible, measurements were made on axial sections in the vestibular and oral direction in the region of the alveolar process between the central incisors, between the canine and the first premolar at the mid-root level, in the region of the first molars below the bifurcation level, in the retromolar region and the region of the articular process. Results: The greatest similarity in densitometric parameters of bone density is established between the second cervical vertebrae and the density of the joint head. The most dense site on the lower jaw is the alveolar process between the central incisors, which increases with age from 1274.71 ± 34.7 in group I to 1400.6 ± 7 5 , 5 6 in the III group, these indicators are almost 2-2.5 times higher than the density of C2. Conclusions: Mandible presents irregular density of bone based on optic denstitometry in different areas. Maximal indices of bone density are established in the area of alveolar processes where the jaw is exposed to maximal occlusal loading.Документ Optical density of upper jaw in patients with malocclusion(2017) Kuroedova, V. D.; Vyzhenko, E. E.; Makarova, A. N.; Galych, L. B.; Chicor, T. A.; Куроєдова, Віра Дмитрівна; Виженко, Євгеній Євгенович; Макарова, Олександра Миколаївна; Галич, Людмила Борисівна; Чикор, Тетяна ОлександрівнаIntroduction: The growth and formation of facial skeleton is in interrelation with growth of cervical spine. Computer tomography plays an important role to examine and investigate the density of bony tissue resulting from total increase of osteopenic diseases and diseases of periodontal tissue. The aim of the paper is to compare indices of mineral density of bony tissue of the upper jaw and mineral density of the second cervical vertebra in patients with malocclusion. Materials and Methods: 37 orthodontic patients were involved in the investigation. They were divided into three age groups depending on the period of formation of dentofacial system. Density measurement of bone of the second cervical vertebra was done and also density measurement of upper jaw in the area of alveolar process between central incisors, canines and the first premolar on the level of the middle of roots, in the area of the first molars under the level of bifurcation and in cusp was performed. Results: Optical density of bone of the second cervical vertebra with age increases from 501±61,06 to 587,6±48,81. The densest area on the upper jaw is alveolar process between central incisors, which increases with age from 1045,14±59,81 to 1318±69,28. The least indices of optical density were determined in area of the cusp of the upper jaw: the first group presented 174,21±38,94, and the third one included 338,87±26,91. Conclusions: Densitometry of bony tissue with computer tomography is diagnostically informative and available method for investigation and it can be used for diagnostics of bony tissue condition and for evaluation of orthodontic treatment.Документ Symmetry of elements of temporomandibular joint (TMJ)(2017) Kuroedova, V. D.; Stasiuk, A. A.; Makarova, A. N.; Trofimenko, K. L.; Vyzhenko, E. E.; Куроєдова, Віра Дмитрівна; Стасюк, Олексій Анатолійович; Макарова, Олександра Миколаївна; Трофименко, Катерина Леонідівна; Виженко, Євгеній ЄвгеновичIntroduction: Dysfunction of temporomandibular joint is present in 70-75% of orthodontic patients. Evaluation of TMJ and detailed characteristics of its elements with additional methods of examination in children and adults is necessary for clinical definition of proposed disturbances of the structure and functions of the joint. The aim of the investigation is to study morphological symmetry ofTMJ in patients with dentofacial abnormalities and with dentofacial abnormalities complicated by secondary edentulism. Materials and Methods: 57 patients were involved in the examination. Based on gender principle patients'distribution was almost equal: there were 30 women and 27 men. Cone-beam computerized tomography (CBCT) Galileos (SIRONA DENTAL, Germany) was used to all patients. Results: It was done analysis of parameters (height and length) of right and left heads (condyles) of temporomandibular joint in both groups. Asymmetry of parameters of heads' length in saggital area in patients of the second group was defined. It was proved statistically (left 10,38±0,76, right 8,16±0,78). Conclusions: Increase of asymmetry of length of heads of TMJ in saggital area with age was determined. It can be explained by complication of dentofacial abnormalities and the presence of secondary edentulism. Depending on bite type length of condyle, especially at prognathism (in saggital) area peculiar clinical problems with TMJ can be present due to asymmetry of condyles. The size ofjoint gaps ofTMJ due to the presence of dentofacial abnormalities with age demonstrates compensatory ability and saves its.Документ The study of temporomandibular joint in dentofacial abnormalities using cone beam computed tomography(The New Armenian Medical Journal, 2018) Kuroiedova, V. D.; Stasiuk, A. A.; Vyzhenko, E. E.; Makarova, A. N.; Sokolohorska-Nykina, Yu. K.; Куроєдова, Віра Дмитрівна; Виженко, Євгеній Євгенович; Стасюк, Олексій Анатолійович; Макарова, Олександра Миколаївна; Сокологорська-Никіна, Юлія КостянтинівнаThe article deals with the symmetry of dentofacial abnormality of temporomandibular joint, the position of mandible and rotation edges of temporomandibular joint heads in dentofacial abnormalities. The aim of the investigation is to compare the analysis of temporomandibular joint symmetry, the position of mandible and rotation edges of temporomandibular joint heads in dentofacial abnormalities based on the first and the second type of classification by Angle. The investigation was carried out among 27 patients with dentofacial abnormalities using cone beam computed tomography. The patients were divided into two groups based on types of malocclusion - the first type of occlusion by Angle and the second one by Angle’s classification. While studying the distance from the middle of articular heads on the right and on the left to midline, passing through pterygoid processes of sphenoid bone it was determined that in the second class of Angle’s classification of dentofacial abnormalities, articular heads are situated posteriorly to cranial basis on 2.45-3.47 mm (р<0.005). The difference between the rotation edges of temporomandibular joint heads is more than 5° of the 1st class according to classification and it occurred in 23.08% of patients; the second class occurred in 64.29%. The range of maximal difference of the rotation edge of the 1st class contains 5.2°, and the 2nd class of Angle’s classification includes 15.2°, that determines the severity of dentofacial abnormality of the second classification by Angle. In the second type of Angle’s classification articular heads of temporomandibular joint are situated posteriorly that confirms the pathogenesis of distal bite. Proposed methods of measurement can be used for differential diagnosis of skeletal forms of second type dentofacial abnormalities according to Angle’s classification. With increase of dentofacial abnormality severity, rotation of temporomandibular joint heads also increases. In the second type of Angle’s classification asymmetry of articular heads occurs on the right and left, three times more often in comparison with the first class.
