ABSTRACT

Objective: To explore the distribution of cariogenic streptococci, infection level and their relationship with incidence of caries. Materials and method: 60 school-children (8 to 10 years of age) followed 18 months. Caries was registered, bacterial counts of streptococci in dental plaque were obtained; by means of biochemical analysis the bacterial typification was obtained, the caries incidence was calculated for the sampled molar. Results: 80% of the streptococci were from the group mutans (40% S. sobrinus, 32% S. mutans, 5% S. rattus y 3% S. cricetus). The remaining 20% were other Streptococci (S. salivarius, S. mitis and S. sanguis). Fifty five percent of children presented counts of ≥ 105 cfu/mL in dental plaque and 30% developed caries in the studied molar. A model of multiple logistic regression of successive multiple steps showed an association between predominant bacteria and level of infection (P ‹ 0.01). No association between predominant bacteria and caries incidence was demonstrated (P › 0.05). However the same model considered for infection level showed a significant association (P ‹ 0.0018). Conclusion: The association of streptococci strains with caries incidence in children is related to the infection level.
