One of the first and most ancient human settlements in Mexico originates in village of Santa María Aztahuacan (located within what is now known as the Delegation of Iztapalapa of Mexico City). Existence of human settlers in Santa María Aztahuacan has been documented as far back as the 14th century. Some of the more important physical characteristics are found in the oralmaxillary features of these ancient settlers. The physical characteristics include anomalies and pathologies in the relationship between the maxilla as well as the overall general health of their teeth. These include ectopic eruption of the superior canine teeth, general occlusal abrasion, and lower third molar agenesis, among others. Detection of these pathologies is important, especially in the area of anthropological dentistry; as the presence of these anomalies dates back to the village of Santa María Aztahuacan during the pre-Hispanic era of Mexican history, thus making them an important part of Mexican’s culture and rich anthropological heritage.
