Comparative cephalometric study of three different ethnic groups of black Africa with normal occlusion.

Introduction: The aim of this study was to investigate if there are differences or not between African ethnic groups in order to determine any ethnic and regional differences in the facial morphology.

Material: Lateral cephalograms of 53 young Ivorians, 50 young Senegalese and 62 young Chadians, obtained under the same conditions in each country, were measured. Ten skeletal, eleven dento-skeletal and twelve soft tissue variables were investigated.
