在海岱地区古代居民中,北辛文化居民最早出现拔牙现象,都是拔除双侧上颌侧门齿,单一形式且高出现率的拔牙现象可能与成年仪式相关。结合考古材料和民族学资料来看,凿、敲或打应该是海岱地区史前居民去除牙齿的主要方式,具体操作应该是用细小且坚硬的工具抵在需去除的牙齿上,然后用石块等工具进行敲打。海岱地区古代居民对去除后的牙齿进行了相对随意或特意的处理,且原牙位空间没有进行其他填充。这种拔牙现象的消逝可能始于大汶口文化晚期,进入龙山文化时期海岱地区的这种拔牙现象出现了整体性的衰落。

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.
