Sexual Dimorphism in Permanent Human Dentition
… ways. We understand the microstructure of the dentition within the sample population may be impacted by some wear and use of dentition within this community. The dental microstructure was examined using 3D modelling in 14 individuals from a sample of the Point Hope population including eight …

Phenotypic Plasticity of Oral Jaw Dentition in Archosargus Probatocephalus
<p>Phenotypic plasticity, the capacity of a single genotype to exhibit variable phenotypes in different environments, is common in many species. A sample of wild caught <i>Archosargus probatocephalus</i>, also known as sheepshead, from Florida was randomly divided into two treatment groups: one …

Concerning the Innervation of the Upper Dentition in Man
<p>The primary objectives of this study were to determine: 1) the pathway of the superior alveolar nerves and their relation to the maxillary molar tooth buds in the fetal and neonatal specimens and in the child, and 2) whether nerve fibers entered any microscopically-observed tooth buds.</p>

What’s in a Tooth? Signals of Ecogeography and Phylogeny in the Dentition of Macaques (Cercopithecidae: Macaca)
… covariation, and allometry were analysed in the dentition, both within and between species. The ecogeographical analysis was carried out by means of two-block partial least squares and a type of multivariate regression, both in a phylogenetic framework. Phylogenetic signal was tested for by means …

An Anthropometric Study of the Face and Dentition of the Apache Indian Population at the Stewart Indian School
… to study the cranial, facial, skeletal and dentitional patterns and compare discriminately to other contemporary North American Indian groups: Pima, Papago, Mayo and Chamula. Materials on other Indian tribes considered were obtained from studies completed at Loma Linda University. The data …

You Should Look a Gifted Mammal in the Mouth: Using Dental Morphology to Understand the Evolution of Mammalian Dentition
Dentition is vital to our understanding of mammalian evolution. In this thesis, I use dental morphology as a basis for investigating various phenomena in mammalian dentition. First, I investigate the utility of shape, form, and linear measurement when differentiating species of the genus Mesodma – …

Analysis of the Blancan Procyonids of Florida
… based on morphology of the postcrania and lower dentition, while another <em>Procyon </em>species is also described as new due to an apomorphy in the upper dentition. A new species of coati (genus <em>Nasua)</em> is identified and described based on lower dentition and postcranial morphology. The …
