These indicators were used to calculate the indices. The analysis of teleroentgenograms was carried out in the online service Mave to the results of anthropometry, the longitudinal and transverse dimensions of the young men's heads, the zygomatic diameter and the full height of the face were assessed the indicators of body growth, body weight, chest circumference and transverse chest diameter were determined. The aimwas to determine the morphometric parameters of the maxillofacial area of Omsk young men of 18-20 years of age according to the teleroentgenography of the head (in a lateral projection), taking into account the indicators of cephalometry and anthropometry, to identify regional constitutional features of quantitative values.Material and methods.A cephalometric and somatometric examination of 26 Omsk Slavic young men of 18-20 years of age without concomitant pathology was performed, supplemented by an X-ray examination of the head (to obtain teleroentgenograms in a lateral projection). Overall, the higher vulnerability of third molar formation could be associated with the evolutionary trend in humans towards a reduced number of molar teeth, which seems to show no sex-related differences.Ĭonstitutional Features of the Maxillofacial Area of Omsk Young Men These findings indicate a strong genetic control of the developmental process of tooth formation, with any disruptions affecting both sexes in a similar manner. For both females and males, bilateral third molar agenesis was approximately three times more frequent in group A than in group B (p < 0.001), whereas no difference was detected for unilateral agenesis. The most common third molar agenesis pattern was that of no third molars. Both sexes showed a higher number of third molar agenesis per individual in group A than in group B. There was no sexual dimorphism in the patterns or the severity of third molar agenesis within groups. Here, we investigated sexual dimorphism in third molar agenesis patterns and severity in non-syndromic white European individuals with (group A: 303 individuals) and without agenesis (group B: 303 individuals) of teeth other than the third molars. Sexual dimorphism in the human dentition is of interest from a developmental, evolutionary, and clinical point of view.
