CLINICAL CHARACTERISTICS OF DEEP BITE IN ADOLESCENTS WITH VARIOUS DEGREES OF SEVERITY OF CONNECTIVE TISSUE DYSPLASIA

Nowadays, dental anomalies in children and teenagers are common pathologies that have a negative impact on the functional state of the organs and tissues of the oral cavity, as well as in general physical development. At the same time, they have a wide range of etiological factors and pathogenetic mechanisms of their development. According to the literature, the problems of occlusion disorders in congenital collagenopathies have not been sufficiently studied, which gave a reason to choose the direction of this research work.

Aim. To study the parameters of anatomical deformities of the alveolar process of the upper jaw in deep bite in children and teenagers with various degrees of severity of connective tissue dysplasia. Materials and methods. A study of 306 children and teenagers with DST aged 12-18 years was conducted, of which 157 boys and 149 girls. Deep bite was diagnosed in 124 schoolchildren. The degree of DST was determined by the method of T. Milkovska-Dmitrova and A. Karkashev (1985). At the medical appointment, after determining the dental status, there was performed a biometric study on plaster models of the patient. To obtain objective data, there was used the standard Pon and Tone method.

Results. Of all the examined groups of children and adolescents with DST, 37.92+1.08 % with deep bite were diagnosed, where the indicator of mild DST was at the level of 41.94+1.01 %, and moderate and severe 30.64+1.21 % and 27.42+1.26 %, respectively. The dynamics of the average statistical data of the premolar index shows an increasing trend for the severity of anatomical deformities of the alveolar process of the upper jaw in the form of narrowing. The dynamics of the molar index at various degrees of severity of DST determines that with a mild degree, narrowing was observed, whereas with an average degree, pronounced expansion of the alveolar process of the upper jaw was diagnosed, where this value decreases to a severe degree.

Conclusions. The established parameters of the values of anatomical deformities of the alveolar process of the upper jaw in deep bite, depending on the severity of DST in children and adolescents, contribute to timely diagnosis and prompt implementation of therapeutic and preventive measures, which accordingly eliminates or minimizes long-term complications of local phenotypic manifestations of congenital collagenopathy.
