Abstract

With the purpose of studying the impact of the cranial base upon the prognathism of the upper maxilla on a sample of 120 cephalograms, the Facial Depth Cephalometric Analysis (FDCA) was used to measure these craniofacial structures and find ethnic, sex, age, and location differences. The cephalograms obtained from a previous data of existing populations of Caucasians and African descents (30 men, 30 women), and a dated population of European descents of the Denver Growth Study (15 men, 15 women during their childhood and adolescence); were used to evaluate the facial depths and the cranial base angle. The Pearson coefficient correlation and student "t" test demonstrated that only S-FC depth affected the facial prognathism (P<0.01), Africans and women presented the greatest prognathism (P<0.01), women had the biggest Ba-S-Na angle (P<0.05) and the shortest S-N length (P<0.01), finally, adolescents showed a growth ofSN length after the age of 10 (P<0.02).
