Assessment of dentofacial variations in monozygotic twins

Abstract

With dentofacial development being a mul4factorial process, we face the ques1on of whether gene#c or environ--mental factors play a larger role in specific phenotypic traits. The use of twin studies allows one to employ gene/c controls to the study such that one can focus solely on traits that may be more environmentally determined. This study involves retrospec0ve as well as current analy0cal measurements between a set of monozygo0c twins to assess gene$c and outside influences on facial and intraoral development. While similari$es were acknowledged, we found differences in measurements of the facial thirds, the congenital presence of mandibular third molars, and the pres--ence of mandibular tori.Cita%on: Tu, V.
