WebThe teeth of the Homo erectus child (Garba IV) recovered from Melka Kunture Ethiopia and dated to 1.5 Ma are characterized by generalized enamel dysplasia, reduced enamel radio-opacity, and severe attrition. This combination of features is found in a large group of hereditary, generalized enamel dysplasias known as amelogenesis imperfecta (AI). WebThis study utilized binocular Wild and Leitz microscopes capable of magnification from 7.5-60x and 10-300x, respectively. The Wild microscope was used to examine items up to 60x, with the Leitz used for magnifications up to 100x and, infrequently, to 300x.
