Abstract:

Background & Aim: Streptococcus mutans (S. mutans) is a causative agent of dental caries and the use of a few conventional foods containing probiotics is an antimicrobial approach. Both Lactobacilli and bifidobacteria can be found in breast milk, suggesting early exposure of the oral cavity to these bacteria. In this study, we aimed to evaluate the effect of probiotic yoghurt drink (doogh) on salivary S. mutans at Dental Islamic Azad University of Tehran, Iran, in 2011. Materials & Methods: In this double-blind clinical trial, 30 dental students were enrolled and divided into three groups. Salivary S. mutans colonies were counted after consumption of probiotic or ordinary yogurt drink. Growth and the number of microorganisms in each group were compared using sign test and their quantity was tested by performing Wilcoxon test; however, intra-group comparisons were made by using Chi-square and Kruskal-Wallis tests. Results: In the ordinary yogurt drink group, salivary S. mutans level was decreased in 16 (55.2%) cases, while in seven cases (24.1%) it remained unchanged, and in six (22.7%) subjects its level was increased; there was a statistically significant difference between the groups in this regard (P<0.02). However, in the probiotic yogurt drink group, level of salivary S. mutan had diminished in 22 (75.9%) cases, but there was no change in two (6.9%) cases, and the bacterium level was increased in five (17.2%) participants. Sign test reflected a significant difference between the groups (P<0.001). Conclusion: Probiotic yogurt drink reduces the level of salivary S. mutans in the oral cavity of humans. The same effects were found for ordinary yogurt drink, but less than the probiotic type.
