Annotation. Studying the relationship between the morphological characteristics of the dentofacial system and the parameters of the craniofacial region is important for understanding the mechanisms of formation of a harmonious bite. Analysis of such correlations allows predicting the features of the development of dental arches and developing personalized approaches to orthodontic treatment. Taking into account individual variations in the size of teeth and their correlation with craniofacial parameters contributes to the optimization of diagnostics and planning of orthodontic intervention. The study of these parameters in representatives of the Ukrainian population allows identifying characteristic morphological features and their variability. The aim of the study was to establish qualitative and quantitative features of correlations between “dental” teleradiometric indicators according to the Ricketts method with the sizes of teeth and dental arches in Ukrainian young men and young women with physiological occlusion without and taking into account the type of face. The computed tomographic sizes of teeth, dental arches and “dental” teleradiometric indicators according to the Ricketts method (distances 6u-6l, Overjet, Overbite, 1l-OcP, 3u-3l and angle Max1-Mand1) were determined from the data bank of the Research Center and Department of Pediatric Dentistry of the National Pirogov Memorial Medical University, Vinnytsya from primary computed tomograms of 41 Ukrainian young men (aged 17 to 21 years) and 68 Ukrainian young women (aged 16 to 20 years) with physiological occlusion. The Garson face types of this contingent were also determined. The assessment of correlations between “dental” teleradiometric indicators according to the Ricketts method and computed tomography dimensions of teeth and dental arches in young men and young women without and taking into account the type of face was carried out in the licensed package “Statistica 6.0” using nonparametric Spearman statistics. As a result of the analysis of reliable and medium-strength unreliable correlations between “dental” teleradiometric indicators according to the Ricketts method with the dimensions of teeth and dental arches, the following was established: in young men and young women without taking into account the type of face - respectively 4.76 % and 14.29 % of connections with the dimensions of the teeth of the upper jaw, respectively 11.43 % and 16.67 % of connections with the dimensions of the teeth of the lower jaw and respectively 8.33 % and 6.48 % with the dimensions of the dental arches; in young men and young women with a wide face type – respectively 13.81 % and 14.29 % of connections with the size of the teeth of the upper jaw, respectively 21.90 % and 12.38 % of connections with the size of the teeth of the lower jaw and respectively 16.67 % and 17.59 % of connections with the size of the dental arches; in young women with a very wide face type – 19.05 % of connections with the size of the teeth of the upper jaw, 19.05 % of connections with the size of the teeth of the lower jaw and 17.59 % of connections with the size of the dental arches. In young men and young women, both regardless of facial type and in representatives with a wide facial type, pronounced manifestations of sexual dimorphism of the relationships between “dental” teleradiometric indicators according to the Ricketts method and computed tomography dimensions of teeth and dental arches were established in terms of the strength, number, and direction of reliable and medium-strength unreliable correlations.
