DENTONI, María Nélida et al. First studies on dental fluorosis in archaeological populations of the province of córdoba (argentina). Rev Arg Antrop Biol [online]. 2023, vol.25, n.1, e063.  Epub Jan 01, 2023. ISSN 1514-7991.  http://dx.doi.org/10.24215/18536387e063.

Fluoride (F-) has properties of great interest in relation to human health. In concentrations lower than 1mgF-/L, it favors the mineralization of hard tissues. However, chronic intake of water with concentrations greater than 1 mg F-/L produces fluorosis. In the province of Córdoba, studies in current populations detected this pathology in different localities. The highest values of F- in water were found in the southern, northwestern and northeastern zones, in contrast to those of the central-western zone, which made it possible to delimit zones with high fluoride content in watercourses. This work aims to evaluate the impact of dental fluorosis in human remains from archaeological sites in the province and relate it to the F- content in the waters of regions near the findings. Thirty-eight individuals (27 male and 11 female) from different regions of the province of Córdoba were analyzed and indicators of dental fluorosis such as hypoplasia and alterations in enamel color were recorded. In addition, the frequencies of caries, root remains, enamel fractures, sequelae of periapical processes and the state of the alveolar tables were surveyed, to assess the oral health of individuals. The results show that 21 individuals (55.3%) have signs of dental fluorosis, 13 males (34.2%) and 8 females (21.0%). The origin of the affected individuals suggests a relative correspondence with the results of current clinical studies and with the levels of fluoride in the waters of the province.
