Avaliação da prevalência de patologias bucais nos oásis de San Pedro de Atacama

Abstract

The Atacama Desert in northern Chile, despite the altitude and dryness that characterize it, displays evidence of human presence for at least 13,000 years. San Pedro de Atacama is a very important region of the desert, for the large number of archaeological skeletons that were exhumed and found there and also for the excellent state of preservation in which the excavated material-whether mineral or organic-was found. Independent teams of researchers have collaborated for the past 50 years to the understanding of Atacamenian prehistory, through analysis of the archaeological and the bio anthropological collection, which are now in the custody of the archaeological museum Padre Gustavo Le Paige. The material analyzed in this dissertation is part of the collection of human skulls excavated by Le Paige, a collection now severely reduced due to deficiencies in the process of safekeeping.

Dental erosion caused by a gastrointestinal disorder in a child from the Late Holocene of Northeastern Brazil

“…Another possible parafunctional activity would be the daily use of teeth as tools for creating artifacts from vegetable fibers, leather, bones, and others. However, neither the lower teeth marks nor the maxillary incisor wear surface is consistent with this usage, not to mention that the child of Burial 2 was less likely to participate in these sociocultural activities (Oliveira, 2014;Larsen et al, 1998;Molnar, 1971). Lazarchik and Filler, 2000).…”

An Early Holocene case of congenital syphilis in South America

“…All deciduous teeth present generalized enamel hypoplasia (except 72 and 82), and 16 of the 18 deciduous teeth are decayed (see Supporting Information S1 and S7 for supplementary information and images) (Oliveira, 2014; Oliveira & Neves, 2015). The teeth lesions strongly suggest syphilis on B20.…”

Dental corrosion in preindustrial societies: A case study of a child from “Pedra do Cachorro” dating to 1,470 BP, Northeastern Brazil

“…It is also important to observe that Burial 2 was that of a young child, and therefore, less likely to participate in these kind of socio-cultural activities (e.g. Oliveira, 2014;Larsen et al, 1998;Molnar, 1971).…”

“…"Abfraction" is a less frequent type of mechanical dental wear observed on archaeological skeletons. Although the precise etiology is still a matter for debate, abfraction is broadly considered to reflect stress concentration on the cervical region of teeth, as a result of excessive cyclic loading (Lanigan and Bartlett, 2013;Lucas and Omar, 2012;Oliveira, 2014). Most likely this excessive loading is a consequence of parafunctional use of the masticatory apparatus.…”
