生前牙齿缺失和牙齿磨损程度被认为与龋齿和牙周炎密切相关，不仅在古人类骨骼遗骸中，在现代人中也是如此。我们在韩国的Yean-ri骨骼系列(公元4世纪至7世纪)中研究了这些特征。男性和女性在AMTL和牙齿磨耗程度上没有显著差异，因此本研究中的男性和女性数据被合并。然而，不同年龄的人之间的AMTL发生率有显著差异，尤其是在下颌骨的后牙。随着年龄的增长，AMTL显著增加。牙齿磨耗程度也与年龄有关，与牙萌出密切相关。牙合龋齿的患病率在伊恩日族骨骼中较低。伊恩-里人吃的食物比现代人吃的食物硬得多，因此，他们的牙齿磨损相当大。咬合龋齿推测不会发生在有咬合面的个体身上，例如严重的磨耗。换句话说，咬合龋齿可能发生在年轻人身上，但在超过一定年龄的人中不会发现，因为牙齿磨损随着年龄的增长而发展。如果牙齿磨损相当严重，轻微的咬合龋齿可能已经由于牙齿磨损而消失，就像现代尼日利亚的情况一样。此外，考古标本中严重的牙齿磨损与龋齿位置密切相关。
Antemortem tooth loss (AMTL) and degree of dental attrition are thought to be closely related to dental caries and periodontitis, not only in ancient human skeletal remains but also in modern humans. We examined these features in the Yean-ri skeletal series (AD 4rd to 7th centuries), South Korea. There is no significant difference between males and females in AMTL and degree of dental attrition, so the male and female data in the present study were pooled. However, a significant difference in the AMTL rate was observed between individuals of different ages, particularly in the posterior teeth of the lower jaw. A significant increase in AMTL was seen with increasing age. The degree of dental attrition was also correlated with age and was closely related to dental eruption. The prevalence of occlusal dental caries was low in the Yean-ri skeleton. Yean-ri people ate food that was much harder than the food eaten by modern day people; therefore, their dental attrition was considerable. Occlusal dental caries is speculated not to have occurred in an individual with occlusal surfaces, such as severe attrition. In other words, occlusal dental caries might have occurred in young people, but it would not have been found in individuals beyond a certain age, as dental attrition progressed with aging. If dental attrition was considerable, slight occlusal dental caries could have disappeared due to dental attrition, as in the modern Nigerian cases. Furthermore, severe dental attrition in archaeological samples was closely related to caries sites.
