Objectives: To determine the effect of the combination chlorhexidine diacetate 1% and sodium fluoride varnish 5% on Streptococcus mutans in the saliva of children 3 to 5 years with white stain. Methods: Were included 45 children, divided into 3 groups: combined chlorhexidine 1 % and sodium fluoride 5 % (n = 15), sodium fluoride 5 % (n = 15) and placebo (n = 15). After 8 weeks was evaluated microbiologically. Results: All groups significantly reduced the S. mutans, combination sodium fluoride 5 % and chlorhexidine 1 % (15.267 ± 9.816; p < 0.05); sodium fluoride 5 %(16.267 ± 7.146; p< 0.05); and placebo (9.467 ± 9.326; p < 0.05). Conclusions: The combined application of chlorhexidine diacetate 1 % and sodium fluoride 5 % is effective reducing of S. mutans in saliva of children.
