Короткий огляд (реферат): Introduction. In recent years, in world literature appeared research, which focuses on the study of relationships craniotypes with odonto-metric indicators, size, shape of the dental arches and occlusion. However, most of the experts focus on the study of individual features of the structure of the teeth jaw system in people with different types of faces and aspects of sexual dimorphism and ethnic characteristics. Studies containing information about cranio-typological variability of the roots of teeth we did not encounter. The aim is to reveal features length of roots of incisors and canines of the upper and lower jaw, according to the CT scan in boys and girls of different craniotypes with physiological bite, residents Podilskiy region of Ukraine. Material and Methods. The study involved young men with orthognathic bite and their cephalometric performance taken from database from Scientific and Research Center Vinnitsa National Medical University named after Pirogov. To make CT used dental cone beam CT scan - Veraviewepocs 3D, Morita. In the upper and lower incisors and canines were measured vestibular-oral and mesio-distal projection length of the root. The height (length) of the root was measured in the medial (or distal) norm, focusing on border basics crowns (root) and the apex of the tooth root. Established the following distribution craniotype: mesocephalic boys -16, boys brachycephalic -19, mesocephalic girls -16, brachycephalic girls- 26. Statistical analysis of the results was performed using the statistical software package licensed "Statistica 6,0" using non-parametric estimation methods. Results. The peculiarities computed tomographic characteristics of root length incisors and canines of the upper and lower jaws in boys and girls Podilskiy region of Ukraine with different craniotypes and physiological bite have been set. In boys or girls mesocephals majority values of vestibular-oral and mesio-distal projection length of the teeth root, medial and lateral incisors in the upper and lower jaws significantly higher compared to studied similar gender brachycephals. Most values vestibular-oral and mesio- distal projection length of the teeth root, medial and lateral incisors in the upper and lower jaws in boys of total group and brachycephals significantly higher compared with girls of similar comparison groups. In boys mesocephals only value of vestibular-oral projection length of teeth root on the lower jaw was significantly higher compared with girls of the same craniotype. Conclusions. In mesocephalic boys or girls majority values of vestibular-oral and mesio-distal length projection of the root teeth, medial and lateral incisors on the upper and lower jaws significantly higher compared to similar brachycephalic genders studied.
