Dental caries is a disease widely spread in the world, therefore, it has been and it is still the most frequent disease of modern man. Due to the high incidence of this oral disease, and to the great need to prevent it, it was decided to conduct this investigation in order to evaluate the connection of the cariogenic microorganisms and some demographic variables with dental caries in children. A case-control analytical study was undertaken in the municipality of Matanzas, province of Matanzas, during the academic course 2004-2005. The study group was composed of 11 311 children aged 6-12. A randomized sample of 900 children (300 cases and 600 controls) was selected. The highest percentage of white children (62 %) were affected by caries, 91.3 % and 40 % of the children from the case group had an elevated degree of infection caused by Streptococcus mutans y lactobacilli, respectively, which showed a positive association between dental caries and these variables.
