对13处遗址的日本新石器时代绳纹人骨骼的龋齿进行了调查。结果表明：（1）早期患龋率低;（2）中期及以后患龋率增加;（3）面向外海的贝冢患龋率可能高于内海的贝冢;（4）晚期和终末期的贝冢患龋率不分部位均不同。根据这些结果，可以说绳纹骨骼中龋齿的发生率根据地理和/或年代环境而不同。也许，这些发病率主要反映了这一时期的各种饮食分化。此外，据推测，绳纹人口的高龋齿率（8.2%）支持了他们严重依赖植物性食物作为主要营养来源的理论。
Dental caries of Japanese Neolithic Jomon skeletons derived from the thirteen sites was investigated. Results indicated that (1) caries is infrequent in the teeth of the early stage, (2) the teeth affected by caries increased in and after the middle stages, (3) the teeth from shell middens facing the open sea possibly has high degree rate of caries rather than those of inland sea, (4) the teeth in the late and final stages, regardless of the locations, had a certain measure of caries. From these results one may say that the incidences of dental caries in Jomon skeletons differ according to geographical and/or chronological circumstances. Perhaps, these incidences mainly reflect various dietary differentiation of this period. Furthermore, it is inferred that the high rate of dental caries in the Jomon population (8.2%) supports the theory that they relied heavily upon plant foods as a major source of nutrition.
