    Abstract:
    PURPOSE: This study investigates the effects of daily consumption of a probiotic ayran drink on gingival inflammation and the development of experimental gingivitis. MATERIALS AND METHODS: This randomised, double-blind, placebo-controlled trial involved 54 volunteer students. The participants were randomly assigned to two groups: the control group received regular ayran for 42 days, while the test group received probiotic enriched ayran (including Lactobacillus acidophilus and Bifidobacterium bifidum) for 42 days twice a day. After 42 days, mechanical plaque control was stopped for 5 days. The plaque index (PI), gingival index (GI), probing bleeding (BOP), and probing depth (PPD) were measured at baseline, day 42, and day 47. At the same time, gingival crevicular fluid was taken for matrix metalloproteinase-8 examination. RESULTS: The mean scores of BOP, GI, PI, and MMP-8 levels increases in both groups following the 5-day experimental gingivitis period compared to baseline and day 42. Patients using probiotic ayran had significantly less PI, GI, BOP scores and MPP-8 values (p = 0.002; p 0.001; p 0.001; p = 0.001; p = 0.001, respectively) at day 47 compared to the control group. No statistically significant differences in probing pocket depth (PPD) were observed at any time point. CONCLUSION: The present study suggests that daily consumption of a probiotic ayran drink containing Lactobacillus acidophilus and Bifidobacterium bifidum statistically significantly lowers clinical and immunological markers of gingival inflammation.
