The three oralTori in the Coimbra population (Portugal) at the beginning of the XXth century A.D.

The remarkable anthropological series formed by E. Tamagnini at the Universidade de Coimbra consists of the exhumed human remains from “La Conchada” cemetery, in Coimbra (Northern Portugal). From this collection, only those individuals coming from the different districts of Coimbra, where they also lived and died, were selected for study. The resulting series was made of by 483 individuals: 234 women and 249 men. The personal data sheets indicate that these people died between 1910 and 1938; their professions, age at death and its cause are also noted. They can be considered as a relatively homogeneous group of low socioeconomical level. The study of the three oraltori demonstrated the high frequencies of all of them, the absence of sexual dimorphism and only a few statistically significant differences between some of the age classes considered. The possible etiological factors (genetical and/or environmental) are also discussed.
