[A cephalometric study of mandibular growth pattern in twins].
Cephalometric method was used in the study of the growth pattern of the mandible in a sample of 40 twin pairs, 20 monozygotic and 20 dizygotic. Zygizity diagnosis of the twins was determined on the basis of the similarity method as well as on the serological investigations. For this investigation sum of the angles of Bjork's polygon (NSAr + SArGo + ArGoMe) was used as well as percentage relationship between posterior and anterior facial heights (SGo/NMe). Both, the Björk's polygon and percentage relationship of the anterior and posterior facial heights were calculated. Intra- and interpair comparisons between monozygotic and dizygotic pairs were calculated. It was concluded that genetic factors played an important role in the control of the type of mandibular growth.
