Torus mandibularis in an Alaskan Eskimo population

One of the lowest reported incidences of torus mandibularis (10.7%) in an Eskimo population was observed in the Wainwright, Alaska group studied during 1968. In this population the tori generally did not appear until after the age of 40 years in contrast to other Mongoloid populations previously reported. There was no size difference between males and females, but the males exhibited a much higher incidence of this exostosis. The tori did not significantly increase in size with increasing age after their appearance late in life.
