Evaluation of Lactobacillus and Streptococcus mutans by Addition of Probiotics in the form of Curd in the Diet.

Background: Probiotics are defined as live microorganisms which when taken in adequate amounts provide a health benefit on the host. They have been used to improve gastrointestinal health, and their popularity has prompted increased interest for their role in the promotion of oral health also. The study was undertaken to evaluate the influence of diet alteration on oral microflora with the addition of probiotics in the form of curd in the diet.

Materials And Methods: Sample pool included total 20 children, 15 in experimental group; who were given curd containing probiotic bacteria in their diet daily and 5 children in control group; who were contradicted of food containing probiotics. All the children were followed for over a period of 1-year. A pre and post quantitative analysis of Streptococcus mutans and Lactobacilli were done in the saliva of both active and control groups, and caries score was recorded.

Statistical Analysis Used: The data thus compiled were statistically evaluated using Chi-square test and Pearson correlation on SPSS software version 14.

Results: In experimental group, 87% children showed decrease and 7% showed increase in S. mutans count (P = 0.83), whereas 67% showed increase and 7% decrease in Lactobacilli count (P = 0.002) after 1-year of follow-up.

Conclusions: Probiotics are upcoming as an intriguing field in oral health. Efforts should be made to increase the knowledge of the general dental practitioners with this facet of oral disease therapy and promote the implementation of the concept of "food rather than medicine."
