The Mayo Indian of Sonora, Mexico, was selected for a study of dental morphology. The objectives of the investigation were to determine the extent to which the Mayo conformed to the four criteria of the Mongoloid dental master pattern, and to compare eight other specific tooth morphologic characteristics with like studies on Mongoloid and non-Mongoloid peoples. Plaster casts were made on a sample of forty-one Mayos.
The results of the study indicate that Mayos exhibit a 46 percent frequency of shovel-shape maxillary incisors, classifying "moderate shovel" and "shovel" together. The maxillary central-lateral width difference of 1.5 mm is small compared …

Loma Linda University Electronic Theses, Dissertations & Projects
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 …
