Abstract:

Among the ancient inhabitants of Haidai region, the earliest dental extractions in the Beixin culture were the removal of bilateral maxillary lateral incisors, and the single form and high incidence of teeth extraction may be related to the rite of passage. Combined with archaeological and ethnographic data, chiseling, knocking or beating should be the main ways to remove the teeth in the prehistoric inhabitants of the Haidai region, and the specific operation should be to use a small and hard tool against the tooth to be removed, then use stones and other tools to knock. The ancient inhabitants of the Haidai region treated the removed teeth relatively randomly or deliberately, and the original teeth space was not otherwise filled. The demise of the teeth extraction phenomenon probably began in the late Dawenkou culture, and the overall decline of the teeth extraction phenomenon occurred in the Haidai area into the Longshan culture period.
