RESUMO
A high rate of occurrence on dens evaginatus (DE) is reported in certain cultural groups in a Chilean population. Factors affecting the reported incidence of DE are discussed as are the clinical complications and treatment requirements related to this anomaly.

Plants traditionally employed for the treatment of malaria in certain areas of Brazil, where this disease is prevalent, were surveyed by interviewing natives and migrants in the Amazon Region. Forty-one plants used for malarial treatment and/or for the related symptoms (fever and liver disorders) were collected and identified. Given the potential of Brazil's forests and medicinal plants, research on traditional plant-based remedies in this country may lead to the development of new drugs.

Tooth mutilation or adornment in ancient Peru and Chile is discussed as well as that seen in present day Nigeria. Dental mutilation must be recognized (diagnosed) for what it is and discouraged in order to prevent dentoalveolar pathology and tooth loss.

The occurrence of mylohyoid groove bridging and jugular foramen bridging was determined in a population of adult Pre-Columbian Chileans. Two hundred forty-one crania (110 males, 131 females) were examined for jugular foramen bridging and 464 mandibles (252 males and 212 females) were observed for mylohyoid groove bridging. The overall incidence of jugular foramen bridging was 14.94%, with females showing a higher occurrence (18.32%) than males (10.91%); however, no statistical significance was found between the sexes. The right side showed a greater incidence than the left, but again no statistical difference was noted and the occurrence of this trait was found to be associated between the sides. This frequency of jugular foramen bridging is higher than that found in other studies and approaches that reported in North American Eskimo populations. In the case of mylohyoid groove bridging, the incidence was 4.09% with no difference found between the sexes. This frequency of occurrence is less than the values reported previously for the other American populations of Mongoloid ancestry including the Pre-Columbian Peruvian population. The importance of nonmetric skeletal traits for defining population groups and their usefulness as anthropological tools is discussed. It is concluded that hard tissue variations such as bony bridging may be reliable markers to aid in discretely identifying population groups, but their importance can be significantly enhanced by coupling as many traits as possible in future studies.

A case of an expansile facial lesion discovered in the more than 600 years old skeletal remains of a 22-25-year-old female is discussed. Gross, radiographic and histological studies were accomplished on the specimen. Although a definitive diagnosis could not be derived because of the age and condition of the specimen, differential diagnoses are discussed and a probable diagnosis rendered.

A case of an expansile, multilocular lesion in a condyle recovered in skeletal remains more than 700 years old is discussed. Gross, radiologic, and histologic studies were accomplished on the specimen. Although a definitive diagnosis could not be arrived at because of the age of the specimen, differential diagnoses are presented.

PIP: The relationship between economic activities and population movement in the Brazilian Amazon frontier is explored. A historical review of the frontier's changing conditions over time is presented. Consideration is given to the original role of the frontier as a destination for surplus population from urban-centered industrial development. The growing influence of the capitalist economy on the frontier since the 1960s, particularly on the region's agricultural development, is also examined. (summary in ENG)^ieng

The mean mesiodistal and buccolingual diameters are presented for the deciduous teeth from Pre-Columbian Peru. Generally, the deciduous teeth from Pre-Columbian Peru are larger in most dimensions than the deciduous teeth of modern populations of European descent and smaller than those of modern Australian aboriginals. Differences in crown dimensions between the Pre-Columbian Peruvian deciduous teeth and those from Prehistoric Inamgaon and Mesolithic Europe are inconsistent. However, the maxillary and mandibular second molars are larger in the Peruvian population while the incisors are smaller. Since comparative data for prehistoric deciduous teeth are rare, this paper adds valuable data to the growing literature on deciduous crown dimensions.

An incidence of tori lower than previously reported was found in a population from Pre-Columbian Peru. It is suggested that the prevalence of tori along with other genetic markers with racial variation may be used to help identify and define a population group.
