ABSTRACT

Method: 139, 12 to 15 years students were screened for DMFT index, their saliva for; buffer capacity, colony counts of mutans streptococci as a degree of infection, salivary IgA antibody response to antigens I/II of Streptococcus mutans determined by ELISA, the reaction specificity was corroborated by immunoelectrotransference (western blot). Results: The mean DMFT index median was 4, the saliva buffer capacity median was 2 which corresponded to an average buffer capacity. The prevalence of infection by S. mutans was 94.2%, the median of the degree of infection was 2 which indicates a moderate infection in the sample studied, the title for antibodies salivary type IgA vs S. mutans antigen I/II presented a median of 0.170. The Spearman bivariate correlation between the buffer capacity and salivary IgA antibody to S. mutans a positive correlation (r = 0.126, P = 0.042) no statistical significance was found among the other variables. Conclusion: In the studied population the median DMFT was 4. Saliva was found with a high presence of S. mutans, observing a moderate degree of infection, median buffer capacity and was observed a positive correlation being statistically significant between the buffer capacity and salivary IgA antibodies vs antigen I/II of S. mutans which resulted specific by the immunoelectrictransference determination.
