Abstract
According to many numerical literary sources, the modern direction of provision of dental care involves an individual approach to the patient, in particular, based on his gender, age and nationality. This calls for the creation of its own regulatory bases for the population of different countries and ethnic groups, taking into account all possible criteria. The purpose of the study is to establish and analyze the cephalometric parameters by the method of E.P. Harvold in young men and women of Podillia region of Ukraine with orthognathic bite. Primary lateral teleroentgenograms of 38 young men and 55 women with normal occlusion close to orthognathic bite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken from the data bank of the research center of the National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of E.P. Harvold. Statistical processing of the obtained results was carried out in the license package "Statistica 6.0" using nonparametric methods of estimating the results. When comparing teleroentgenographic indices between boys and girls of the Podillia region of Ukraine with orthognathic occlusion, significantly higher values of the length of the upper and lower jaw, lower facial height and interjaw differences in young men were established, and Ap1uAp1l-DOP angle was significantly higher in young women. When comparing these data with the results obtained by E.P. Harvold, the boys and girls of the Podillia region of Ukraine with orthognathic bite have significantly lower values of the length of the upper and lower jaw and lower facial height. In addition, Ukrainian young women have significantly higher values of the Ap1uAp1l-DOP angle and a tendency to lower interjaw differences, while in young men, the tendency towards higher values of the cross-sectional angle than the value of these parameters obtained by E. Harvold is established. The results of the study confirm the need to create a normative basis for teleroentgenographic indices by the method of E.P. Harvold for the population of different regions of Ukraine, taking into account both sexual and age affiliation.
Highlights
The face as the most open part of the human body plays many key roles in the modern human life, and in particular performs aesthetic function
If we talk about the lower part of the face, the aesthetic function is ensured due to a smile and, in general, the correct arrangement of all structures of the lower face of each other
In order to correctly assess the interrelationship of these entities, a cephalometric analysis based on the study of specific points, lines, planes and angles is used [14]
Summary
The face as the most open part of the human body plays many key roles in the modern human life, and in particular performs aesthetic function. In order to correctly assess the interrelationship of these entities, a cephalometric analysis based on the study of specific points, lines, planes and angles is used [14]. There are numerous methods of cephalometric analysis of lateral teleroentgenograms, each of which has its own characteristics. Like other methods, Harvold's analysis has a significant drawback - norms laid down in this technique are specific because the study was conducted on Canadians who had European ancestors. The modern direction of provision of dental care involves an individual approach to the patient, in particular, taking into account his gender, age and nationality
