Correlations between teleradiometric indicators according to the Steiner method and the sizes of teeth and dental arches in Ukrainian young men and young women with physiological occlusion and a wide facial type

Annotation. Studying the features of craniofacial development in individuals with different facial types is important for optimizing orthodontic planning. Teleradiographic indicators according to the Steiner method allow us to assess the spatial relationships of the jaws, teeth, and soft tissues of the profile. The analysis of correlations between cephalometric characteristics, tooth sizes, and dental arch parameters in patients with harmonious occlusal development is relevant. This allows us to better understand the anatomical and functional patterns of the maxillofacial region in adolescence. The purpose of the study is to establish the features of the relationship between teleradiometric indicators according to the Steiner method with the sizes of teeth and dental arches in Ukrainian young men and young women with a physiological bite and a wide facial type. A morphometric study of computed tomography dimensions of teeth and dental arches was conducted and teleradiometric indices were determined using the Steiner method of primary computed tomography of 25 young men and 25 young women with physiological occlusion and a wide face type according to Garson, which were obtained from the data bank of the Department of Pediatric Dentistry and the Research Center of the National Pirogov Memorial Medical University, Vinnytsya. The assessment of correlations between teleradiometric indices using the Steiner method and computed tomography dimensions of teeth and dental arches 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 teleradiometric indicators according to the Steiner method with the sizes of teeth and dental arches in young men and young women with a wide face type, it was established: in young men – 10.00% of similar correlations with the sizes of teeth of the upper jaw (mainly unreliable direct correlations of medium strength), 11.25% with the sizes of teeth of the lower jaw (mainly reliable and unreliable direct correlations of medium strength) and 13.89% with the sizes of dental arches (mainly reliable and unreliable direct correlations of medium strength); in young women – 18.75% of similar correlations with the sizes of the teeth of the upper jaw (mainly reliable and unreliable direct and unreliable reverse of average strength), 18.75% with the sizes of the teeth of the lower jaw (mainly reliable and unreliable direct and unreliable reverse of average strength) and 33.33% with the sizes of the dental arches (reliable and unreliable direct and reverse, mainly of average strength). Thus, in Ukrainian young men and young women with a physiological bite with a wide facial type, the peculiarities and gender differences of the relationships between teleradiometric indicators according to the Steiner method and computed tomography sizes of teeth and dental arches have been established.
