Hadza Oral Health Research

Team Members: Peter S. Ungar, Alyssa Crittenden, John Sorrentino, Jerry Rose

Funding Source: US National Science Foundation

We are examining oral health in the Hadza peoples of Tanzania. Our research is focusing on changes in caries rate, periodontal disease, orthodontic disorders and developmental defects associated with the transition from hunting and gathering to an agriculture-based economy.

Surface Micro-Morphology Characterization of Non-Carious Lesions (NCCLs)

Team Members: Anderson Hara, Sarah V. Livengood, Frank Lippert, Peter S. Ungar

Non-carious cervical lesions (NCCLs) are clinically characterized by tooth substance loss in the region close to the gingival margin or, more specifically, at the cemento-enamel junction. Their development may involve dental erosion, toothbrushing abrasion and/or deflection forces. NCCLs are responsible for affecting the form, function and aesthetic of the teeth and can, often times, be associated with tooth sensitivity.
The long-term goal of this project is to study the development of NCCLs under well controlled conditions, quantifying the tooth loss rate and characterizing the surface micro-morphology of the NCCLs resulting from different dental wear processes individually or in association.

Surface Analysis of Brushed Enamel Surfaces

Team Members: Sarah V. Livengood, Anderson Hara, Frank Lippert, Peter S. Ungar

This project investigates the ability of SSFA and ISO parameters to determine/predict the enamel/dentin abrasivity of toothpastes as an alternative to the current radiotracer method.
