The Sinodont dental complex found in East Asia and the Americas represents a suite of specialized traits (e.g., shoveling, enamel extensions, deflecting wrinkle, 3-rooted lower molars, 4+ cusped lower molars, and missing-peg-reduced UM3).
The TCMT is an important marker in sinodont populations, and with a high frequency in indigenous Colombians between 60% and 100% (9).
The first subdivision, or Sinodont, composed of Northeast Asian populations, is characterized by the addition and enhancement of some TCMTs, such as the shovel-shaped and layered fold incisors, along with the Y6 cusp pattern, the protostylid (cusp forms) and winging.
Edgar (2007) (19) grouped humans into five clusters: the Mongoloid Dental Complex formed by sinodont and sundadont groups; the Caucasoid Dental Complex formed by Western Eurasian groups (Europe, North Africa, Middle East and India); the Saharan African Dental Complex (composed of West African and South African subgroups closer to sundadont populations of the South Pacific), several Pacific groups of Sahul or Oceania and American Paleo-Indians who present frequencies and morphological variations that take them out of the complexes described.
However, an examination of the dentition revealed a Sinodont dental pattern, particularly observable in the female, with an exaggerated shovel-shaped incisor of the Sino-American type.
It is considered to be an important marker of sinodont populations of Northeast Asia grouped in the Mongoloid dental complex.
We must take into account that, according to Turner, (24) the American continent was initially occupied by sinodont human groups--first subdivision of the Mongoloid dental complex--characterized by shovel-shaped incisors, deflecting wrinkle, Y6 cusp pattern, protostylid, and winging, such as the case of populations of Northern Asia that migrated from Northern China and crossed Beringia.
Este RMDC no se ha asociado a algun complejo dental mundial, pero sus frecuencias mas altas se observan en los sinodontes, primera subdivision del complejo dental mongoloide.
Inicialmente, se usaron muestras asiaticas para proponer que los Sundadontes son poblaciones del Sureste de Asia que demuestran un patron de simplificacion y retencion de algunos rasgos, mientras que los Sinodontes corresponden al Noreste de Asia y presentan mayor diversidad demostrando un patron de adhesion e intensificacion de nuevos rasgos (Turner 1971, 1979, 1984, 1985, 1987, 1990, 2002; Greenberg et al.
Para el problema de la relacion asiatica con los primeros americanos, se plantea que los Paleoindios provienen de grupos originarios del Noreste de Asia, entre la region de los rios Lena y Yenisei, es decir Sinodontes (Turner 1979).
Todos estos rasgos morfologicos son parte de un complejo dental mongoloide, especificamente de los sinodontes, lo cual coincide con la teoria sobre el origen mongoloide de los indigenas de America del Sur.
All of these morphological features are part of a Mongoloid dental complex, specifically of the sinodonts, which agrees with the theory of the Mongoloid origin of South American indigenous populations.
