The Effect Of Antemortem Tooth Loss On Craniofacial Shape In Apes And Humans, Ashley R. Laster

Biological Sciences Undergraduate Honors Theses

Antemortem tooth loss (AMTL) (i.e., defined as tooth loss occurring before death) is common among humans and many primates, and several studies have examined AMTL across various primate groups. Some research indicates that AMTL can influence masticatory function and diet; however, the effects of AMTL on craniofacial shape and biomechanics have not been extensively analyzed. We assessed craniofacial and mandibular shape in relation to AMTL, anticipating that individuals with at least one tooth lost antemortem would display significant differences in cranial and/or mandibular shape compared to those without AMTL. AMTL rates were evaluated in three primate species: wild-caught samples of …

Establishing An Objective, Quantifiable Method For Detecting Erosive Tooth Wear, Camille Kita

Biological Sciences Undergraduate Honors Theses

This study aims to monitor and evaluate erosive tooth wear (ETW) by measurement of enamel surface thickness and texture in a clinical setting. The objective approach is fundamentally different from the standard subjective visual assessment that professionals in the dental field using the Basic Erosive Wear Evaluation (BEWE) method.

Twenty-nine hyposalivation and three control subjects were used in this longitudinal study, for a total of 597 samples (only 577 teeth were eligible for surface texture analysis) evaluated in a longitudinal study including both baseline and 12 month follow up surfaces. Each participant’s buccal surface of the tooth was first analyzed …

Clinical Assessment Of Erosive Tooth Wear Objective Outcome Measures, Elizabeth Wewers

Biological Sciences Undergraduate Honors Theses

The purpose of this study was to determine whether enamel surface texture can be used as objective and quantitative measurements to detect and monitor erosive tooth wear (ETW) as an adjunct to the subjective Basic Erosive Wear Evaluation (BEWE) that is commonly used today. This longitudinal observational clinical study enrolled 32 subjects with a sample of n = 584 teeth. Conventional dental microwear surface texture parameters (surface complexity, roughness, and anisotropy - Asfc, Sa, Str, respectively) (were generated using white-light scanning confocal profilometry) from the buccal surfaces of each tooth accepted to the study. I personally scanned and analyzed n …

Molar Macrowear As A Proxy For Age In A Captive Sample Of Papio Hamadryas, Lauren Conrad

Biological Sciences Undergraduate Honors Theses

This study is methods-focused, centering around molar crown macrowear and its performance as a proxy for age in a sample of pedigreed, non-human primates. It analyzes the correlation between age-structured variables and molar wear among both males and females in a captive group of baboons. Here, I examined whether wear is significantly correlated with age-related variables (i.e., generations/cohorts) and whether the structure of the “age” dataset differed across wear categories. Because chronological age is unknown, I used documented pedigrees and parent-offspring relationships to group individuals into possible generations. I then used dental development charts to group individuals into cohorts based …

Heritability Of Maxillary Dental Arch Dimensions In A Pedigreed Sample Of Hamadryas Baboons, Samuel Park

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

This thesis presents a study of heritability of maxillary dental arch dimensions in a captive baboon colony. Arch dimensions are important subject because they influence the entirety of the craniofacial and masticatory complex. The goal of this study was to quantify the relative genetic influence on arch dimensions and the nature of this influence at different points along the maxillary arcade. Referencing virtual, three-dimensional dental cast scans, widths were measured at different points between the a) maxillary left and right canines, and b) maxillary left and right first molars (M1). Specifically, measurements were taken at the inner (lingual) gingival margin, …
