Size relationships among permanent mandibular molars in Aboriginal Australians and Papua New Guinea highlanders

Article Abstract:

Two samples of Aboriginal Australians and Papua New Guinea Highlanders were taken to study the size relationships among crown units of permanent mandibular molars. Measurements of first, second, and third molars (M1, M2, M3), including overall mesiodistal and buccolingual diameters as well as the mesiodistal and buccolingual diameters of the trigonid and talonid, were obtained.

Quantifying trabecular orientation in the pelvic cancellous bone of modern humans, chimpanzees, and the kebara 2 Neanderthal

Article Abstract:

Quantifying trabecular orientation above the acetabulum is the aim of the study to test the hypothesis that hominoid biomechanical behavior is recorded in the cancellous bone. The variations in the Fast Fourier Transforms (FFTs) spectrum between species is discussed in the light of distinctive biochemical features.

Decline in Enamel Hypoplasia in relation to fluoridation in Australians

Article Abstract:

The major current overviews establish that generalized development stress between ages 0-5 underlines most permanent tooth hypoplasias. Fluoridation of metropolitan water has emerged as the statistically strongest hypoplasia-preventing factor.
