Descripción histopatológica del desgaste dental en dientes pertenecientes a una población prehispánica de Nariño.

. To munch leaves is the indigenous form, that consists of chewing a blend of coca plant, ash, limestone, and something else, A recent study realized on contemporary samples showed that to munch leaves can cause dental wear with unique microscopic characteristics, different from those caused by attrition or erosion. And also, recently it was pre-Hispanic department of Nariño, where evidence of dental wear was found, but it is not confirmed if these injuries are similar to the habit of munching. Objective. To explain the topography of the worn dental surface in teeth of a pre-Hispanic people of the department of Nariño. Materials x and Methods. Three dental samples come from two different individuals, dating from the pre-Hispanic period, were gotten from a population in this zone, All the ethical aspects received approval by the dental ethics council Excavation samples were found in University in this place, the samples were gotten because of the help of the archeology group association in south of the country, who realized the excavation and gave approval to this samples for research purposes. The teeth were analyzed macroscopically, and also a fragment was obtained from each tooth that was metallized and analyzed in scanning electron microscopy (LYRA 3 TESCAN microscope). Results. macroscopically, wear of up to 3 apparent dentin involvement was seen, in addition the wear pattern showed a form of striae on the occlusal surface. In the microscopic analysis, cracked enamel surfaces, microfractures, cavities, aprismatic surfaces, discontinuous depressions and interlamellar spaces were observed in the occlusal surface. Conclusion. The results of this study show that the microscopic findings of the pre-Hispanic samples are similar to those produced by the habit of chewing the coca leaf or "munching “further studies are required to confirm the practice of munching in the people from this place.
