Aim: to analyse the 33 cefalometric factors included in the six fields of Rickets analysis in a sample of Brazilians, and compare these values with cefalometric standards for North American individuals. Methods: after having been chosen 75 Brazilian leucoderms, with age between 12 and 15, with better aesthetic aspects, balance, face harmony and mainly with excellent dental occlusion, results of a search in 14,000 students attending elementary and high school, in the area of Marília, Assis and Ourinhos/SP, all of the 33 factors of cephalometric measures of the 75 individuals were compared with the results obtained for Ricketts, in a sample of american leucoderms. Results and Conclusion: 1) under skeletal level, the maxilla presented a behavior according to the author’s proclaimed patterns. The jaw showed a more horizontal development trend in its branch; 2) under tooth structure level, the lower incisors located more foregoing and with bigger bending. The horizontal, vertical trespassing and the lower incisors extrusion presented themselves perceptibly increased, probably due to the jaw horizontal development trend; 3) related to “E” ‘Ricketts’ aesthetic planning, the lower lip showed a more anterior location related to the author’s claimed pattern; 4) The clinical deviations, in the most part of the factors, were very bigger in Brazilians than in Americans, probably related to the bigger miscegenation in the Brazilian leucoderms.
