根据骨骼和牙齿的形态学数据，九州北方的弥生人被认为是移民或他们的后代。他们或他们的祖先被认为将农业，特别是水稻种植引入了日本。冲绳史前贝冢文化中期，相当于绳文晚期和弥生早期，冲绳人的生存方式被认为是狩猎和采集。本研究比较了狩猎采集者和农耕者的牙齿患病情况。在以往的研究中，发现农民的龋齿比率高于狩猎采集者。此外，在所研究的样本中，被认为是由周围牙周病引起的牙齿缺失和牙根龋在老年农业家中突然增加。因此，周边牙周病被认为是在弥生时代传播到北方九州的农学家。
Based on morphological data from bones and teeth, Yayoi people in northern Kyushu are thought to have been immigrants or their descendants. They or their ascendants are thought to have introduced agriculture, especially rice growing to Japan. During the middle period of the prehistoric shell midden culture on Okinawa island, equivalent to the latest Jomon and early Yayoi period, the subsistence of Okinawa islander is thought to have been hunting and gathering. In the present study, the dental morbid condition of the hunter-gatherers and the agriculturalists is compared. As reported in previous studies, the carious teeth ratio of the agriculturalists was found to be higher than that of the hunter-gatherers. Moreover, the missing teeth and tooth root caries, those are thought to have been caused by peripheral periodontal disease, abruptly increased in the elder agriculturalists in the samples studied. Therefore, peripheral periodontal disease is thought to have spread to agriculturalists in northern Kyushu during the Yayoi period.
