Many published studies express that the presence of extrinsic black stain on the enamel of tooth surfaces in children and adolescents is associated with less dental caries (CD) activity, this being valid for both primary and permanent dentition. The objective or this researh was to carry out a multifactorial approach to know the relationship between the presence of extrinsic black stain and the presence of caries, in a population of the city of Córdoba, Argentina. Methods. A case-control study (5: 1) was carried out in patients of both sexes from 3 to15 years of age, between the years 2016-2019, who were attended by spontaneous request to the Chair "A" of Pediatric Dentistry, of the Faculty of Dentistry, from the National University of Córdoba (n = 184). All patients underwent a Clinical History. Stimulated saliva was extracted for calcium and phosphate determination and dental biofilm was taken to measure CFU / mL of Streptococcus mutans and Lactobacillus spp. Results. The prevalence of extrinsic black spot was 1.78%. No significant association was found between sex, age and types of dentition between the groups studied. In the problem group, a lower amount of CFU / mL of S. mutans and Lactobacilluss pp was found, a higher concentration of calcium and phosphate and a lower caries index of the primary dentition. Patients with extrinsic black spot had a much lower rate. Conclusions. The extrinsic black spot could be an element of protection against caries, the recommendation for patients who present them would be to remove them from the visible areas and keep them in the rest of the dental elements.
