[Incidence and structure of maxillodental abnormalities in twins].
Dental examinations were carried out in 208 twins (104 pairs), 60 of these monozygotic and 148 heterozygotic. Anthropometric studies of the diagnostic models of the maxilla were carried out in 78 children. The incidence and structure of maxillodental abnormalities and the specific significance of some of these abnormalities in their total structure in both groups of twins were determined. The degree of differences in pairs of twins was evaluated on the basis of anthropometric parameters and individual abnormalities. The highest level of hereditary influence was observed for the width of dentition and distal occlusion.
