Systematic review of randomized control trials; searched Scopus, PubMed, and Web of Science databases according to specific inclusion and exclusion criteria in October 2022

Objective

This systematic review examines the effectiveness of Lactobacillus reuteri as an adjunct to scaling and root planing in the treatment of chronic periodontitis.

Materials and methods

Scopus, PubMed, and Web of Science databases were searched according to specific inclusion and exclusion criteria in October 2022. Randomized control trials that evaluated the effects of Lactobacillus reuteri in patients with periodontitis were included. The primary outcome was pocket depth and clinical attachment levels, while the secondary outcome considered was bleeding on probing, microbial levels, and gingival index score. Study quality was assessed based on the Cochrane Handbook for Systematic Reviews of Interventions and the ROB2 tool.

Results

A total of eleven studies that examined 369 subjects were included in the review. Adults in the age group of 18-70 years of age suffering from chronic periodontitis were evaluated. Eight out of the eleven studies reported statistically significant improvement in the intergroup pocket depths, whereas seven studies showed a statistically significant reduction in the clinical attachment levels in the probiotic group. Three studies showed no significant improvement in the pocket depth levels in the probiotic group as compared to the controls. Four studies showed no significant reduction in clinical attachment levels between the two groups. The overall risk of bias was high in four studies, while seven studies reported some concerns about the risk of bias.

Conclusions

Based on the limited evidence available, the adjunctive use of Lactobacillus reuteri to scaling and root planing may provide some additional benefit in improving periodontal parameters.
