[Oral status of persons with dysplastic phenotype living in different climatic and geographical conditions].

In the circumpolar region the share of persons with CTD and dysplastic depended changes of dento-maxillary system is statistically higher than on the territory of moderate latitudes. In the presence of CTD caries spreading and parodontium inflammatory diseases increases considerably but in the circumpolar zone the changes are significantly marked. The further study of the role of some factors including confounding in the dysplastic phenotype forming and stomatological pathology in the different climatic and geographical zone conditions is required.
