Abstract

Lateral head x-rays were obtained on selected samples of 24 Chamula, 29 Mayo and 39 Navajo Indians for cephalometric comparison.

Cephalometric evaluation was carried out by means of the Bjork analysis. Mean values for each of the Indian groups were determined and compared with each other and with the mean values of a group of Swedish conscripts studied by Bjork. The mean values were statistically analyzed and and subjected to the Student's "t" test to determine the significant levels of differences.

Results revealed that in comparing the three Indian groups significant differences do appear. They are few and general concordance in the skeleton and dentition is apparent. The Mayo and Chamula Indian groups show greater similarity to each other than to the Navajos, Comparison of the three Indian groups to the Swedish conscripts show a high percentage of significant differences although some profile aspects of the Navajos and Swedish conscripts show some similarity.
