Peculiarities of the correlation between teleradiometric indicators according to the Tweed 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. Modern orthodontics actively investigates the relationship between craniofacial parameters and morphometric characteristics of the dentition. Particular attention is paid to the search for patterns between the bone landmarks of the skull, the shape of the jaws and the features of the dental apparatus in individuals with harmonious facial features. Such studies are important for improving diagnostics, predicting the growth of the maxillofacial region and planning individualized orthodontic treatment. The aim of the study is to establish the features of correlations between teleradiometric indicators according to the Tweed method with the sizes of teeth and dental arches in Ukrainian young men and young women with physiological occlusion with a wide face type. A morphometric study of teleradiometric indicators according to the Tweed method, computed tomography dimensions of teeth and dental arches of 25 Ukrainian young men and young women with physiological occlusion with 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, was conducted. The assessment of correlations between teleradiometric indicators according to the Tweed method and computed tomography dimensions of teeth and dental arches was carried out in the licensed package “Statistica 6.0” using non-parametric Spearman statistics. When analyzing reliable and medium-strength unreliable correlations between teleradiometric indicators according to the Tweed method and the sizes of teeth and dental arches in young men and young women with a wide face type, the following were found: in young men – 11.22 % of similar correlations with the sizes of the teeth of the upper jaw (mainly unreliable direct of medium strength), 13.67 % with the sizes of the teeth of the lower jaw (medium strength, mainly reliable and unreliable direct and unreliable reverse) and 26.98 % with the sizes of the dental arches (mainly medium strength reliable and unreliable direct and unreliable reverse); in young women – 14.08 % of similar correlations with the sizes of the teeth of the upper jaw (mainly unreliable straight), 17.55 % with the sizes of the teeth of the lower jaw (mainly medium-strength unreliable straight and reverse) and 21.43 % with the sizes of the dental arches (mainly medium-strength reliable and unreliable straight). Thus, in Ukrainian young men and young women with a physiological bite with a wide facial type, the features and gender differences of the correlations between teleradiometric indicators according to the Tweed method and computed tomography sizes of teeth and dental arches have been established.
