“…Moreover, the frequency of shoveling among the Indonesian population had been found to be rather high (86.1%) [13] published the Asian population dental complex termed "Mongoloid Dental Complex." Accordingly, one characteristic of this complex was the high frequency of shovel-shaped upper incisors [14].…”

To determine whether anterior and posterior tooth crown traits exhibit sexual dimorphism and identify traits characteristic to the Mongoloid race, especially among the Indonesian population. Material and Methods: This study cross-sectional study analyzed 108 dental casts from 36 males and 72 females. The traits analyzed included winging, shoveling, double shoveling, canine mesial ridge, canine distal accessory ridge, hypocone, metaconule, Carabelli's cusp, protostylid, metaconulid, enteconulid, and hypoconulid. All tooth crown traits were scored based on the ASUDAS scoring system. Descriptive statistics were used to calculate the absolute and relative frequencies. The Chi-square tests was used to determine significant differences in anterior and posterior tooth crown traits between males and females. Level of significance was set at 5%. Results: None of the traits showed sexual dimorphism. Moreover, the most common traits among the Mongoloid race were hypocone (94.4%) and shoveling (86.1%). Conclusion: Although none of the traits exhibited sexual dimorphism, most of them had a higher incidence among females than males. Nonetheless, further research including adequate samples and a similar number of females and males, is needed, especially for population studies.

“…While cranial size and shape provide more of a mirror on environmental factors (Katz et al 2017), tooth development is strongly canalized and developmentally invariant. Data include metric traits (linear measurements such as length and width of a tooth crown) and nonmetric traits (discrete or quasicontinuous features involving the presence, absence, or graded expressions of a trait; Hemphill 2016a, 2016b; Irish 2016; Pilloud and Kenyhercz 2016; Pilloud et al 2016; Scott and Turner 1997).…”

Biological Distance Patterns Among the Northern Moche Lords: Dental Phenotypes and Political Organization in Ancient Peru

et al. 2018

Between AD 100 and 800, the Moche culture emerged on the north coast of Peru. Diverse debates surround the nature of Moche territorial and political centralization, sociopolitical identities, and the internal social diversity of Moche society. Here we address some of these issues in a biodistance study based on phenotypic variation of inherited dental traits within and between 36 individuals in the royal tombs of Sipán (Lambayeque valley), Úcupe (Zaña valley), and Dos Cabezas (Jequetepeque valley). Metric and nonmetric dental trait data were analyzed using hierarchical cluster and R-matrix analyses. The results independently indicate that the highest-level Sipán and Dos Cabezas lords likely represented different endogamous kin groups, while limited gene flow occurred between groups of Moche lower nobility between the Lambayeque and Jequetepeque regions. Although biology and material cultural link the Lord of Úcupe to Dos Cabezas, many objects in his tomb demonstrate his participation the world of the Sipán elites. These Moche lords were, on some levels, bioculturally interconnected. Nonetheless, the data broadly lend support to a “many Moches” model of sociopolitical structure, further casting doubt on earlier one-dimensional visions of a centralized hegemonic Moche polity.

“…Later works revised Hanihara's (, ) population denominations Mongoloid and Caucasoid to Sinodont (Southeast Asia), Sundadont (Northeast Asia and Native American), and Eurodont (European; Scott, Anta, Schomberg, & De La Rue, ; Scott & Turner, ; Turner, , ), in addition to examining a fourth population, Afridont (African; Irish, , ). These population groups are still used today, but while they are not all inclusive, Pilloud et al () argue that they provide a basis for discussion in dental morphology research. As our understanding increases concerning the interplay between the environment, the genome, and the distribution of human variation, researchers have started to examine global patterns of trait frequencies within and between populations.…”

Forensic anthropologists assist law enforcement agencies and medical examiner's offices with investigations involving human remains, providing insight into trauma analysis, the establishment of postmortem interval, and the estimation of biological profile data. Ancestry is considered one of the more difficult aspects of the biological profile, due in large part to the complicated relationship between skeletal morphology and social constructs. The methods used to estimate ancestry rely on the correlation between skeletal morphology, geographic origin, and an individual's social race. While there is a well‐documented contemptible history associated with the development of ancestry estimation methods in biological anthropology, many of the more traditional, now antiquated, methods are still used in some laboratories. The push to improve the framework within which ancestry data are analyzed requires validation and reassessment for each method in addition to the development of novel approaches utilizing modern technological advances. An array of software programs designed to aid in ancestry estimation is available. These advances do not signal the end of ancestry‐related research. Indeed, several areas seemingly stagnated by tradition and time require further study through more than simply review and rarefaction. The future of ancestry estimation research centers on: (a) abandoning the trait list approach, (b) rejecting the three‐group model, (c) establishing larger and more representative reference data, (d) assessing the utility of mixed method models, and (e) developing new statistical approaches and updating current software tools.
