Dental Investigations of Greenland Eskimos.[Summary.]

Abstract

Prognosis: The opening of these cysts allows rapid growth of new bone to take place and the cavity fills in; this has already happened in this case after six months.The patient will be kept under careful observation; any sign of activity in the two unopened cysts will indicate surgical interference.

Oral health in prehistoric San Pedro de Atacama oases, Northern Chile

“…As already mentioned, dental calculus can be the result of the ingestion of animal protein, and consequently the production of urea (Ford, 2009;Pedersen, 1947). However, other dietary sources of calcium, phosphate and potassium could also have promoted the steady increase in calculus deposition (Poff et al, 1997) from the Pre-Tiwanaku to the Post-Tiwanaku period (Llagostera, 2004;Lynch, 1977).…”

Intrapopulation variation in macro tooth wear patterns—a case study from Igloolik, Canada

“…For sample sizes, see Table 1. For explanation of plot symbols, see objects such as a bow drill (de Poncins, 1941;Pedersen, 1947;Mayhall, 1972). 2.…”

“…In addition, it seems likely that their diet of predominantly meat and fat would not have been as abrasive as many vegetable food stuffs even though eating frozen or sun-dried meat might have required vigorous chewing (Waugh, 1937;Pedersen, 1947;Davies and Pedersen, 1955). Merbs (1983: 147) observed that the anterior teeth were used to tightly grasp a piece of meat while it is sliced by a knife, and ''a bite sized morsel is cut off and swallowed after little or no mastication.''…”

“…There is strong evidence for sexual division of labor among the Inuit, including the Inuit of Igloolik (Mayhall, 1972). The ethnographic and anthropological literature also suggests that the tasks Inuit females used their anterior teeth for, such as softening seal hide, would have been performed more frequently and for longer periods than the tasks performed by males (Nansen, 1893;Leigh, 1925;Waugh, 1937;de Poncins, 1941de Poncins, , 1949Pedersen, 1947Pedersen, , 1949Davies and Pedersen, 1955;Mayhall, 1970Mayhall, , 1972Mayhall, , 1977Hylander, 1977), which might also account for the higher wear ratios in the anterior teeth of the females from Igloolik. Merbs (1968) makes an interesting observation that Inuit males tended to use their anterior teeth in tasks involving objects of small diameter, thus concentrating pressure on a small number of teeth.…”

Dental Caries Incidence in North and South Dakota Indian School Children during 30 Years

“…Only one in 25 adult females living in the more primitive communities of West Greenland were affected by dental caries, while one in two adult females living in communities adjacent to trading stations were affected. 5 15, 1965. rates have been reported in Alaska and elsewhere by Russell.7 Dental caries has affected almost 100 per cent of the populations in the United States and in most of the countries of Europe, and there has been consistent evidence that the prevalence of dental caries has been increasing. 8' 9 In 1936, Mountin and Townsend'0 reported observations of dental defects in American Indians in 24 reservations.…”
