Dental decay (a/k/a caries) · Can signal when hunter-gatherers transitioned to agriculture

This is because decay is linked to a carbohyrdate-rich diet.

Research · Confirms connection between eating carbohydrates and dental decay

Leigh showed decay rate differed between populations that mainly ate meat and those that mainly ate maize (a carbohydrate). On average, the more agriculture, the higher the rate of decay.

Connection not universal · Some nonagricultural populations can have high decay rate

Example: People who ate lots of stone-ground flour had high decay. Some wild plants have high decay-causing potential, too.

███████ █

Discovery of Ban Chiang remains · Show that people transitioned from hunter-gatherer to agricultural society

Connection between agriculture and dental health · More agriculture tends to result in more dental caries

Factors that can affect caries rate · Wearing down of tooth surface can both increase and decrease caries

Ban Chiang diet · Was diverse, but also included carbohydrates

In theory, more rice and yams in the diet should have meant more caries.

███ ███████████ ██ ██████ █████████ ██ ███ █████ ███ ████ ███ ██████ ██████ ████████ ████ ███████ ██████ █████████ ██ ████████ ███████ ██ ███ █████ ██████ █████ ████ ████████ ██ ███ ████████ █████ ████ ███████ ███████ █████ ███ ████ ██████ ████ █████ ███████ ████ ██████████ ████████ ██ ██ ████ ██████ █████ ████████ ██████████ ██ ███████████ ██████████ ███ ████ ██ ███ ████ ██████ ████████ ██████ ██████ ████ ██ ██████ ████ ██████████ ████████████ █████ ███ ████ ████ █ █████ ████ ███████ █████████████ ██████ ██████ █████ █ ████ ██████████ █████████████

Unexpected result · More caries among early Ban Chiang, even though they had less agriculture than later Ban Chiang

This is probably because even though later people had more agriculture, the diet was still diverse, and there may have been shift from yams to rice, which causes less decay than yams.
