Three‐dimensional analysis of the maxillary first molar crowns of Canadian Inuit
Abstract 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 m...
