Transcript of The Effects of Diet on Dental Morphology in Asia

The Effects of Diet on Dental Health in East Asia
Pathologies Studied
Caries - the demineralization of teeth resulting in tooth decay. Often seen as escalating during and after the transition to agriculture. A good indicator of dental health trends in a population.
Antemortem Tooth Loss (AMTL) - tooth loss before death resulting in remodeling of bone. Can be an indicator of dental health or cultural trends.
Primary Diet
Yangshao - Millet based diet with supplements from fishing, animal husbandry, and other agricultural products.
Thai - Rice based diet with supplements from fish, fruit, nuts, and animal husbandry.
Yangshao - A Chinese neolithic culture originating along the Yellow river. Practiced agriculture with an emphasis on millet. Matriarchal society and known for their pottery.
Non Nok Tha - also known as the "partridge mound" it is a burial site for surrounding communities stretching from the neolithic to the bronze, and even iron, ages.
Noen U-Loke - an iron age habitation site in Thailand that is still inhabited even today. Had established rice agriculture and limited hunting and gathering for food.
Results - Yangshao
Moderate levels of dental caries were found, closely related to other cultures with multiple forms of subsistence. Rates of AMTL were higher but not abnormally. Support for dental agenesis and ablation was also found which could contribute to AMTL.
Region of Study - China and Thailand
Results - Non Nok Tha & Noen U-Loke
Non Nok Tha - low levels of dental caries, with moderate levels of AMTL. Tooth ablation was thought to exist in this culture which can contribute to higher levels of AMTL.
Noen U-Loke - also had lower levels of dental caries.
Yangshao dental health declined with the adoption of agriculture but not to an alarming degree.
Thai dental health did not decline or got better with the adoption of agriculture.
