Molecular studies indicate that epigenetic events are important in determining how the internal enamel epithelium folds during odontogenesis. Since this process of folding leads to the subsequent arrangement of cusps on molar teeth, we hypothesized that intercuspal distances of human molar teeth would display greater phenotypic variation but lower heritabilities than overall crown diameters. Intercuspal distances and maximum crown diameters were recorded from digitized images of dental casts in…

Heritability and genetic integration of tooth size in the South Carolina Gullah.

Estimates of narrow-sense heritability and genetic pleiotropy for mesiodistal tooth dimensions for a sample of 20th century African American individuals suggest lower overall heritability relative to other human populations and much stronger genetic integration across tooth classes than obtained from nonhuman primate genetic Pleiotropy estimates.

Gaining New Insights into How Genetic Factors Influence Human Dental Development by Studying Twins

The results indicate that the contribution of additive genetic effects to phenotypic variation differs considerably between different dental traits, and well-designed studies of twins, coupled with modern genome-scanning approaches, offer great potential to identify key “dental” genes and to clarify how these genes interact with the environment during development.

Heritability: the link between development and the microevolution of molar tooth form

It is concluded that the enamel knot cascade does impose constraints on the evolution of molar shape, but that it is so permissive that the divergences among soricines do not fully explore its confines.

Size and Shape Variability in Human Molars during Odontogenesis

The findings suggested that the pattern of size variability would be caused by temporal factors such as the order of cusp initiation and the duration from the beginning of mineralization to the completion of crown formation, whereas shape variability may be affected by both topographic and temporal factors.

Associations between Carabelli trait and cusp areas in human permanent maxillary first molars.

It is suggested that the pattern of folding of the internal enamel epithelium in developing molar crowns, particularly in the protocone region, can be modified by a developing Carabelli cusp.

Intercusp relationships of the permanent maxillary first and second molars in American whites.

Weak statistical dependence between cusp relationships and traditional MD and BL diameters suggest that separate stage- and location-specific molecular signals control these different parts (and different stages) of crown formation.

The presence of accessory cusps in chimpanzee lower molars is consistent with a patterning cascade model of development

Results demonstrate that a patterning cascade model is appropriate for interpreting cusp variation in Pan and have implications for cusp nomenclature and the use of accessory cusp morphology in primate systematics.

The situation, then, is that Carabelli's trait is developmentally correlated with crown size, but with no apparent alteration of cusp arrangements, suggesting that the increases are isometric across the occlusal table.



Genetic and environmental contributions to variation in human tooth size

There were significant levels of non-additive genetic variation in MD diameters of canines and first premolars, which is consistent with selective pressures acting on these teeth at some stage in human evolution.

Intercuspal Distances of Maxillary Pre-molar Teeth in Australian Aboriginals

It appears that the sex differences, which are observed in overall crown dimensions, are established after the cusp tips are localized, and intercuspal distances appear to have a strong genetic component of variability, although they show high phenotypic variability and fluctuating asymmetry.

It was concluded that within this tooth type, there is a large amount of individual variation not only in gross morphology but also in enamel ultrastructure, which underscores the fact that interspecific comparisons must be made with care.

Genotype, phenotype, and developmental biology of molar tooth characters.

The whole cusp pattern is a product of a dynamic developmental program manifested in the activation of the developmental modules, and this patterning cascade mode of cusp development can be used to explain the variational properties of dental characters and character states related to cusp initiation.

Model for the examination of evolutionary trends in tooth development.

Serial C-t scans were used to compare two distinct developmental stages represented by the dentine-enamel junction (DEJ) and outer enamel surface (OES), respectively, in mandibular DM2 and M1 of 31 archaeological specimens, supporting the hypothesis that differences between the two teeth increase throughout development.

A gene network model accounting for development and evolution of mammalian teeth

Large morphological effects frequently can be achieved by small changes, according to this model, and similar morphologies can be produced by different changes, consistent with why predicting the morphological outcomes of molecular experiments is challenging.

In order to ascertain whether or not complete topical and metrical correspondences exist between the enamel and dentin surfaces, a study was made of 50 lower first molars, and it was assumed that the daily rate of formation of enamel proceeds uniformly throughout theEnamel crown.

Three-dimensional measurement of the morphological relationship between molar occlusal surface and enamel-dentin junction

The results indicated that the volume of enamel in M3 was smallest among the three lower molars, and the differences in the thickness of the enamel between the region of the cuspal tip and the groove were shown to be related to the Differences in the heights of thecusps between the EDJ and theEnamel surface.
