Consumption of Probiotics on Salivary Bacteria Causing Dental Caries

Evaluation of the Consumption of Probiotics on the Bacteria Causing Dental Caries: A Randomised Clinical Trial

Dental caries is a multifactorial disease effecting majority of the human population.One of the etiological factor causing dental caries is salivary mutans streptococci. Reducing the levels of this bacteria in the saliva can significantly reduce the incidence of dental caries. A non-invasive intervention, such as the administration of probiotics reduced the salivary mutans streptococci levels.

40 candidates were selected from a pre-determined group and were randomly assigned to two groups. Group A (n=20) was administered probiotic drink and Group B (n=20) was administered placebo for 14 consecutive days. Saliva was collected on day 1 and day 15 to compare the salivary mutans streptococci levels.
