The structure and prevalence of dento-maxillary anomalies and deformations in adolescents with hereditarily caused pathology

Abstract

The high frequency of connective tissue dysplasia (CTD) in the pediatric population, its negative impact on the course of diseases of the dentoalveolar system predetermine the need to make additions to the standards of diagnosis and treatment of this category of patients. Depending on the severity of external phenotypic manifestations and laboratory, clinical and instrumental signs, among 114 adolescents 12–16 years old with general pathology, as well as the clinical symptom complex of CTD, groups with mild, moderate and severe undifferentiated dysplasia were formed. The control group consisted of 37 adolescents of the I and II health groups, matched by sex and age. The first stage of CTD diagnostics involves the identification and scoring of external dysplastic signs, the second stage of diagnostics includes an indepth clinical and instrumental examination to identify visceral CTD manifestations. It was found that the prevalence of dentoalveolar anomalies and deformities in combination with signs of undifferentiated connective tissue dysplasia in adolescence exceeds the frequency of detecting dentoalveolar anomalies and deformities in children of the control group by 1.4–10.9 times. It has been proven that the most informative phenotypic signs in patients with CTD and occlusive disorders are stigmas from the maxillofacial region (anomalies in the position of the teeth, high (Gothic) palate, deformation of the Spee occlusal curve, narrowing and deformation of the dentition, anomalies of attachment of the frenum of the tongue and lips ), bone-skeletal (hypermobility of joints, flat feet, clinodactyly, osteochondrosis, poor posture, anomalies of the skull, deformities of the limbs and chest), ectodermal (hyper-extensibility of the skin, thin, easily injured skin) and muscle (hypotonia of muscles). The presence of at least six informative dysplastic signs in dental patients is an objective criterion for an unclassified CTD phenotype.
