People of the Samurai Class Kept their Antemortem Lost Teeth
Three hundred and fifty-seven skeletons were excavated from the old site of the Sougenji temple in Kitakyushu City, Fuknoka Prefecture, Japan, in 1992. These skeletons were remains of the samurai class and had been buried during the seventeenth or eighteenth century (Edo period). To clarify samurai dental habits, we examined their teeth and alveolar condition. Alveoli could be detected at least partly in 141 skeletons. Detailed examination reveal…
Nonmetric dental characteristics of the early modern population of Okinawa Island in Nansei Islands, Japan
Dental morphological characteristics of the early modern population (c. 17–19th century AD) of Okinawa Island, Nansei Islands, were investigated to clarify their genealogical characteristics. We observed and classified 25 nonmetric traits of tooth crowns and roots from human remains (106 individuals) excavated from tombs of the early modern period in Okuma, Ginowan City, Okinawa. The incidences of these traits were compared with the incidences in…
Preliminary analysis of regional differences in dental pathology of early modern commoners in Japan
The family register system used by the Tokugawa shogunate limited the ability of commoners to move freely from one location to another. It is thought that such restrictions on movement resulted in regional differences in lifestyle, including diet, arising from regional environmental differences. It is also likely that regional differences in lifestyle resulted in regional differences in health status, including oral health. In the present study, …
Population history of the northern and central Nansei Islands (Ryukyu island arc) based on dental morphological variations: Gene flow from North Kyushu to Nansei Islands
This study investigates dental morphological variations among the modern inhabitants of Tanegashima Island and Okinawa Main Island of the Nansei Islands (Ryukyu island arc), which is the southern gateway of the Japanese archipelago. Temporal variations within Tanegashima Island and regional variations of the northern half of the Nansei Islands were used to study population history. The late Aeneolithic Yayoi to protohistoric Kofun populations (c.…
Pathology of deciduous teeth in the samurai and commoner children of early modern Japan
The strict class system in place during the Edo (early modern) period in Japan is thought to have encompassed customs that differed between the samurai (ruling class) and commoners. This study found that in samurai children, deciduous caries occurred only in maxillary incisors at 0.5–2 years of age and did not occur in the mandibular incisors and canines at 3–5 years of age. Conversely, in commoner children, deciduous caries occurred in all maxil…
Low AMTL ratios in medieval Japanese dentition excavated from the Yuigahama-minami site in Kamakura
Ante-mortem tooth loss (AMTL) in a medieval Japanese ‘Yuigahama-minami’ population excavated at Kamakura, Kanagawa prefecture, was examined. In the medieval period, Minamoto Yoritomo established the shogunate in Kamakura, and many battles were fought around Kamakura. Human skeletons from the medieval sites in Kamakura are considered to be casualties of these battles. The AMTL ratio in Kamakura medieval skeletons, as reported in previous work, is …
A possible case of prophylactic supra-inion trepanation in a child cranium with an auditory deformity (pre-Columbian Ancon site, Peru)
We had the opportunity to examine a pre-Columbian Peruvian child (about 4–5 years old) cranium with a healed lesion above the inion on the occiput. It has previously been claimed that supra-inion lesions represent traces of prehistoric trepanation for ritual or prophylactic reasons in childhood, a practice termed ‘trepanation supra-iniana’. An alternative hypothesis claimed that such lesions mainly result from abnormal long-term compression cause…
Dental pathology in the samurai and commoners of early modern Japan
The class system in place during the Edo (early modern) period in Japan is thought to have included a range of customs that differed between the samurai (ruling class) and commoners. The incidence of caries in the dentition of the samurai was significantly lower than that of commoners. This difference is considered to be due to diet, eating frequency, and tooth care. As to location of the caries, it was found that the incidence of root caries in …
The Relationship between Immigration and the Prevalence of Dental Caries in the Yayoi People
Skeletal remains of the Yayoi people, who had been excavated from Northern Kyushu and Yamaguchi Prefecture in Japan, are thought to be largely the descendants of continental immigrants. Carious ratios of the Yayoi people are higher than those of the Jomon people and their descendants. Results of the present study showed that, in frequency of carious lesions and in state of dental attrition, the Yayoi people of the Northern Kyushu and Yamaguchi re…

Japanese Deciduous Tooth Size: Past and Present
Deciduous tooth crown measurements were investigated among the inhabitants of the Japanese islands over the past 4000 years. Mesiodistal and buccolingual crown diameters were measured in Neolithic Jomon, Aeneolithic Yayoi (divided into the samples from Tanegashima island and from other western Japanese sites), protohistoric Kofun, medieval, early modern Edo, modern Japanese and early modern Sakhalin Ainu samples. Overall deciduous tooth size decr…
Dental Morbid Condition of Hunter-Gatherers on Okinawa Island during the Middle Period of the Prehistoric Shell Midden Culture and of Agriculturalists in Northern Kyushu during the Yayoi Period
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 …
Deciduous dental morphology of the prehistoric Jomon people of Japan: Comparison of nonmetric characters
Morphological variations of the deciduous dentition are as useful as those of the permanent dentition for determining the biological affinities of human populations. This paper provides material on morphological variations of deciduous teeth of the prehistoric Japanese population from the Late and the Latest Jomon Period (ca. 2000–ca. 300 B.C.). The expression of nonmetric traits of the deciduous teeth in the Jomon sample shows a closer affinity …
Incidence of Nonmetric Cranial Traits in the Pre-Columbian Cranial Series from the Chancay Site, Peru
The incidence of nonmetric cranial traits in the Pre-Columbian Peruvians from the Chancay site was examined, and their affinities with several Mongoloids, in particular with the other American Indians were determined by comparison of nonmetric data. Distance analyses based on the MMDs demonstrated that in company with the Ontario Iroquois and the Chicama, the Chancay form a cluster of the native American Indians, which is the most distant from th…
Tooth Size of the Protohistoric Kofun People in Southern Kyushu, Japan
Metrical dental characteristics were investigated in the Kofun series in southern Kyushu. The results of t-tests and Penrose's size distances showed that tooth size in the Kofun series in southern Kyushu was larger than those of the Jomon series and the Yayoi series in northwestern Kyushu, except for the buccolingual diameters in males of the Yayoi series, which were almost equal in size, although smaller than that of the Yayoi series in northern…
Genealogical position of native Taiwanese(Bunun Tribe) in East Asian populations based on tooth crown morphology
The 17 tooth crown traits of the Bunun, one of the aboriginal tribes in Taiwan, were observed and classified, and their frequencies were compared with Sinodonts and Sundadonts defined and classified in East Asian populations by TURNER (1987), in order to estimate the genealogical position of the Bunun tribe in East Asia. In the respective comparisons of the 17 traits, the Bunun have considerable resemblance to Sinodonts on shoveling (UI1), double…
Physical characteristics of human skeletal remains from Tomari cave in Himi city, Toyama prefecture
富山県氷見市泊洞穴出土の下顎骨を欠く頭蓋と肋骨片からなる人骨(以下,泊洞人)はそのフッ素含量が完新世前期から更新世末期に比定される(松浦,1985)。この人骨は20歳代前半の男性のものと推定される。頭蓋は全体的に小型である。脳頭蓋の特徴は短•高頭,顔面頭蓋のそれは低•広上顔である。更新世末期から現代に至る各時代人集団との形態学的比較分析によれば,泊洞人頭蓋の全体的な特徴は縄文時代人に,特に上顔面部などは早•前期の縄文時代人に近似する。このことからその所属年代は少なくとも縄文時代,多分その前半にまで遡れるものと考えられる。しかし,さらに更新世末期まで遡れるか否かは現時点では言及できない
