Shinkaruk-Dykovytska M. Incidence rates of teeth and their dependence on the phenotypic characteristics of somatic healthy men from different regions of Ukraine

Regional peculiarities lesions of different groups of teeth by caries and its complications established in somatic healthy males of Ukraine, according to the dental and computed tomographic examination; indices of the intensity of dental caries (CFR), of resistance of teeth enamel to caries and of oral hygiene level are determined with and without the different levels of the CFR. It is proved that the use of cone-beam computed tomography allows more correctly assess the condition of the teeth than standard clinical dental examination. Determined that dermatoglyphics picture in somatic healthy men of Ukraine is formed mainly by genetic contribution persons with low and middle levels of the CFR and the largest deviation from the population picture fixed in males with very high levels of the CFR. In males from different regions of Ukraine with low CFR level specific set of dermatoglyphics signs are not revealed. This fact testifies to the conformity of their state of health of the complete physical health. In males from the southern and northern regions with middle CFR level established specific complex of dermatoglyphics features that distinguish them from representatives of other ethno-territorial regions of Ukraine with the same level of caries intensity. Revealed differences of dermatoglyphics indices between somatic healthy males with low and middle CFR levels within the respective regions of Ukraine indicate the possibility prognosis the course of caries in each ethno-territorial regions. The peculiarities of significant relationships between the level of the CFR or resistance of tooth enamel to caries and dermatoglyphics indices are established. Proved that most of them relate to the intensity of dental caries lesions. Stronger correlations found in men of western, eastern and southern regions of Ukraine. The obtained results have allowed to developed predictive mathematical models of predisposition to a certain level of dental caries intensity or teeth enamel resistance to caries, depending on the specific set of dermatoglyphics indices.
