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.
