Cephalometric Indices among Nigerians

Abstract

Cranial measurements and indices are used to estimate the sex and race. The study was conducted with a total number of 409 students of university of Jos, st Murunba and school of Higher Islamic secondary school Jos. Eight cephalometric indices namely cephalic index, upper facial index, nasal index, cranial modul, cranial length-heigth index, cranial breadth-height index, mean-basion index, mean-height index were calculated. It is concluded that the various indices calculated above agree with the description of Bass of the Negroid cranium as opposed to the Caucasian cranium. The Bass description is that of racial classification of the cranium based on the numerical values of the various cranial indices calculated.
