CONDE SUAREZ, Heberto F; VALENTIN GONZALEZ, Federico  e  GOU GODOY, María Alina. Summarized Ricketts' cephalogram: Analysis by ethnic groups and genre in 9 years-old children. Rev. Med. Electrón. [online]. 2010, vol.32, n.1. ISSN 1684-1824.

A descriptive transversal study was carried out in 9 years-old children living in the city of Matanzas, with the objective of determining the existence of significant differences between ethnic groups and genres applying the summarized Ricketts´ cephalogram. We took a sample of 63 children divided into 4 groups (male Europoid, female Europoid, male Negroid, and female Negroid). Lateral cranial teleradiography were made to all the children and summarized Ricketts´ cephalograms were traced on them. 11 variables were studied, stating by statistical analysis that 4 of them had significant differences between ethnic groups, but not between genres when the subjects belonged to the same ethnic group. These findings are very important when diagnosing individuals and determining the behavior to follow in treating each patient.
