The high incidence rate and wide range of musculoskeletal pathologies determine the improvement of the diagnostic process. Late diagnosis leads to complications, which in turn increase the percentage of disability. Therefore, the search for the most informative method with the least radiation load on the patient remains an urgent problem for radiologists. Cone beam computed tomography (CBCT) is a modern and promising technique that has already found wide application in dentistry and otorhinolaryngology. Among the advantages of CBCT are: three-dimensional image; high spatial resolution; low radiation dose. Thanks to technical improvements in equipment and the introduction of new image processing protocols, it has become possible to expand the indications for conducting the researches, including the researches based on imaging of the upper and lower extremities. Based on the results of a CBCT study, we can evaluate: the shape and contour of the bone; solution of continuity of the bone and malposition of bone fragments; the structure of bone tissue and the pathological processes occurring in it (destruction, osteoporosis, osteosclerosis); joint congruence and changes in articular surfaces surrounding soft tissues. Therefore, CBCT can be introduced into the diagnostic process of bones and joints diseases. The use of this technique will find wide application in traumatology and orthopedics (fractures, dislocations, post-traumatic deformities, aseptic necrosis, osteoarthritis), rheumatology (rheumatoid arthritis, polyarthropathy, juvenile arthritis, gout), surgery (osteomyelitis), oncology (benign and malignant bone tumors) both in the adult population and in pediatric practice. This paper presents a review of the literature, which examines the degree of development of the issue of using CBCT and describes study protocols and protocols for processing the obtained images in the diagnosis of musculoskeletal diseases.

The article presents the results of studying the degree of mineralization of the peripulpal dentin in healthy children and in children with osteogenesis imperfecta according to the data of cone beam computed tomography. In teeth with malformations of heavy tissue tissues, in particular with imperfect osteogenesis, pathological changes are noted in the special enamel and dentin involved in teeth and root canals. The study of the observed characteristics of the distribution of peripulpal dentin in dangerous intact teeth and teeth with malformations of hard dental tissues is of great interest. Subject. Of the study is the degree of mineralization of the peripulpal dentin in permanent intact teeth in healthy children and in children with osteogenesis imperfecta. Objectives. The degree of mineralization of periculpar dentin in children with osteogenesis imperfecta and in healthy peers in permanent intact teeth according to cone-beam computed tomography. Methodology. The study was performed at the Department of Pediatric Dentistry and at the Department of Radiation Diagnostics of the Moscow State Medical University named after A.I. Evdokimov in the Department of X-ray and Radiation Diagnostics of the CCCHLPHIS Clinic of the Moscow State Medical University named after A.I. Evdokimov. The study involved 22 patients aged 7 to 14 years. Results. In the group of children with imperfect osteogenesis in permanent molars with completed root formation, obliteration of the tooth cavity and wide root canals are noted. In the group of healthy children with permanent intact molars, no expansion of the tooth cavity and root canals was noted, no signs of root canal obliteration were detected. The average density of dentin in permanent molars in the group of healthy children is significantly higher than in children suffering from osteogenesis imperfecta. Conclusions. Cone-beam computed tomography is an objective method of visualizing the teeth of both jaws, which allows with minimal radiation load and high accuracy to determine the density of periculpar dentin in permanent teeth in children in one study. Pronounced violations of the mineralization of hard tissues of teeth in children with osteogenesis imperfecta and require further study as the child grows up at the stages of dental rehabilitation.
