A new, three-dimensional method for determining tooth wear
A new technique combining moiré contourography and digital image analysis allows the three-dimensional description of molar wear. It is possible to describe the amount of tooth material lost in a given time, e.g. mm3/year, and the differing amounts of wear on individual cusps. The moiré technique can be used in conjunction with more conventional quantitative techniques or by itself to assist in age determination in a population. It can be used to…
Torus mandibularis in 45,X females (Turner syndrome)
Ninety-three Finnish females with a 45,X chromosome constitution, 78 first-degree female, and 37 first-degree male relatives were examined to determine the frequency and expression of torus mandibularis. The results indicate that among adults the frequency of the trait was significantly lower and the expression weaker in the 45,X females than in male control relatives. A similar trend was observed in comparison to normal females. In juveniles the…

Three‐dimensional analysis of the maxillary first molar crowns of Canadian Inuit
The maxillary first molar crowns of 48 male and 38 female Canadian Inuit (Eskimos) were analyzed three‐dimensionally by using moiré contourography methods. Cusp heights were significantly higher in males while the mesial and distal marginal ridges were more proximally placed in males. The metacone and the oblique ridge appeared to be better developed in the males. Comparison of the present results with published results for Dutch and Japanese ind…
Dimensional and discrete dental trait asymmetry relationships
Inuit (Eskimos) from the Foxe Basin region of the Northwest Territories, Canada, were studied to ascertain the amount of dimensional and morphological asymmetry in their dentitions. The results indicate that dimensional asymmetry does not appear to be greater on either the maxillary or mandibular teeth. Both types of asymmetry show partial conformity to the model of tooth fields with an increasing amount of asymmetry as one goes distally in each …
A correlation of tooth wear and age among modern Igloolik Eskimos
The level of molar wear can be estimated reliably by measuring the cusp height. A correlation between age and the level of molar wear, expressed by a normalizing index (TWI) of cusp height, was found to exist in a sample of modern Igloolik Northwest Territories Eskimos. Not only was it possible to derive linear regression models to test the degree of correlation in the sample of 46 female and 39 male maxillary casts of Igloolik Eskimos, but the m…

Canadian Eskimo permanent tooth emergence timing
To identify the times of emergence of the permanent teeth of Canadian Eskimos (Inuit), 368 children and adolescents were examined. The presence or absence of all permanent teeth except the third molars was recorded and these data subjected to probit analysis. Female emergence times were advanced over males. Generally, the Inuit of both sexes showed statistically significant earlier emergence times than Montreal children, except for the incisors. …
Analysis of contingency table data on torus mandibularis using a log linear model
The hypothesized sexual difference in the incidence of torus mandibularis in Eskimoid groups, as well as age and group differences, was studied in two Northwest Territories Eskimo groups and in an Aleut group (examined by Moorrees). The data were analyzed using statistical methods new to the field of anthropology. The method analyzes data sampled from a multinomial distribution. A hierarchy of log linear models are fitted to the cell counts of a …
Torus mandibularis in two Northwest Territories villages
A study of 433 Canadian Eskimos from the villages of Igloolik and Hall Beach, Northwest Territories, revealed an incidence of torus mandibularis of 39.7% in Igloolik and 37.3% in Hall Beach. No statistically significant differences in size or incidence were noted in a comparison of males and females of the two communities. Further, there were no significant differences in the expression and incidence of the torus between the two villages. The inc…
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 sig…
