Comparative characteristics of the morphological structure of teeth in children with I and III types of osteogenesis imperfecta (in vitro)
Relevance. Osteogenesis imperfecta is a rare hereditary disease of the connective tissue and the skeleton caused by incomplete mineralization of the bony tissue and hard dental tissue of the primary and permanent dentition. The most common oral manifestations of osteogenesis imperfecta are polymorphism, anodontia, impairment of amelogenesis and dentinogenesis. Function and esthetics are impaired in hereditary amelognenesis imperfecta and dentinogenesis imperfecta.Materials and methods. 36 children aged from 4 to 6 years with different types of osteogenesis imperfecta were examined in the clinic of the department of pediatric dentistry of the Clinical Center for Maxillofacial and Plastic Surgery and Dentistry. Morphological structure of the dental samples was studied for the first time ever using scanning electron microscopy.Results. Characteristic changes were detected by the clinical and X-ray examination. The article presents for the first time the comparison of deciduous hard dental tissue morphology in children with different types of osteogenesis imperfecta studied by the scanning electron microscopy (in vitro).Conclusions. The received data are of primary importance for prognosis and strategy of the dental treatment in children with different types of osteogenesis imperfecta.
