Abstract
Context: Although Lactobacilli as a probiotic was established as a treatment for a wide range of systemic infections, its role in periodontitis and oral microbiota is still under investigation. Aims: The present randomized clinical trial was aimed to evaluate the effects of probiotic chewable tablets containing Lactobacillus reuteri UBLRu-87 along with initial periodontal therapy on clinical parameters and oral microbiota of chronic periodontitis (CP) patients. Settings and Design: The randomized controlled clinical trial. Subjects and Methods: Thirty CP patients were selected who received scaling and root planing (SRP) and were randomly allocated into two treatment groups; Groups A and B. Group A received L. reuteri -containing chewable probiotic tablets. The clinical parameters (plaque index, gingival index, probing pocket depth, clinical attachment level), and microbiological parameters ( Porphyromonas gingivalis and L. reuteri levels using real-time polymerase chain reaction) were evaluated at baseline, following treatment at 1 month and 3 months in both groups. Statistical Analysis: Paired t -test and unpaired t -test were used for the statistical analysis. Results: On intergroup analysis, statistically significant improvement in clinical as well as microbiological parameters was observed in Group A (SRP + PROBIOTIC) compared to Group B (SRP ALONE) at all evaluation time points. Conclusion: Probiotic chewable tablets containing L. reuteri may be a useful adjunct along with initial periodontal therapy to slow recolonization of periopathogens along with improvement in clinical outcomes of CP. Further long-term trials are necessary to establish the optimal dosage of probiotics.
