Indicators of dermatoglyphics as markers for the construction of mathematical models for the risk of dentognathic anomalies

Abstract

Summary. Dermatological examinations are widely used in the diagnosis of many congenital and acquired diseases. It is proved that indicators of dermatoglyphics can be used as markers of a polygenic system for the study of some patterns of phenotypic manifestation of polygenic systems in ontogenesis. Investigating the relationship between finger drawings and dentognathic anomalies can help in the early detection of individuals with genetic predisposition.

The aim of the study – to develop prognostic mathematical models of the possibility of dentognathic anomalies in men and women based on the analysis of the features of dermatological characteristics.

Materials and Methods. Dermatoglyphic study was performed using H. Cummins and Ch. Midlo in 34 men and 36 women with dentognathic anomalies aged 35–44 years. As a control, the results of dermatological studies 43 healthy men and 44 women of the same age were used.

Results and Discussion. Discriminant models with the help of dermatological indicators allow the city residents of Uzhhorod to be divided into healthy and sick with dentognathic anomalies. The greatest contribution to discrimination between healthy and sick men is the length of the line аd on the right hand, and between healthy and sick women, the presence of the axial triadius t ‘, the Kamins index and the length of the line ct on the left hand.

Conclusions. Discriminant models of dentognathic anomalies, depending on dermatoglyphic parameters, are adequate and can be used for early prediction of the risk of developing this disease.
