Genetic analysis of occlusal variation in twins.
TLDR
Genetic variance and heritability were estimated for a series of arch and occlusal traits in sixty twins using recently developed methods that are unbiased by variance heterogeneity between zygosities, suggesting considerable amounts of hidden environmental determinance.About:

A heritable component for external apical root resorption in patients treated orthodontically
TL;DR: Quantification of a transmissible component suggests it would be useful to search for the biochemical factors controlling the familial differences in susceptibility to EARR, and heritability estimates were fairly high, although low for the mandibular incisor, probably because of little variation.

A Genetic Contribution to Dental Caries, Occlusion, and Morphology as Demonstrated by Twins Reared Apart
TL;DR: New evidence for a marked genetic component to dentate status and dental caries experience is provided and previous reports of acknowledged inherited contributions to tooth size, malalignment, occlusion, and morphology are confirmed.
Journal ArticleDOI
An epidemiologic transition in dental occlusion in world populations.
TL;DR: It is suggested that an equally clearly defined epidemiologic transition characterizes malaligned and discrepant dental occlusal relations in western societies, and others undergoing urbanization, and that the rapidness of the transition is proportional to the rapidity of urbanizational change.
Journal ArticleDOI
Heritability of craniometric and occlusal variables: a longitudinal sib analysis.
TL;DR: This study was based on serial assessments of untreated persons in 30 sibships from 4 years (full deciduous dentition) to 20 years of age (full permanent Dentition) in the Bolton-Brush Growth Studies of Ohio.

The relative effect of nature and nurture influences on twin differences.
TL;DR: The data employed in this study consist of a portion of the material gathered for an extensive investigation of identical and fraternal twins, and a large number of criteria were used by Professor Newman in classifying twins according to these two types.

A genetic study of class III malocclusion
TL;DR: The explanation most compatible with the results seems to be a polygenic method of transmission depending on a threshold beyond which persons are at risk, as well as a simple autosomal dominant mode of transmission.
