PurposeThis study aimed to evaluate the effect of the use of chewable probiotic tablets on interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-alpha) levels in gingival crevicular fluid (GCF) in patients undergoing treatment with fixed orthodontic appliances. MethodsThis prospective case-control study involved 60 patients undergoing treatment with fixed orthodontic appliances. Participants were divided into two groups. The test group was administered probiotic chewable tablets (Motiflor AS, Abfen Farma, Ankara, Turkey) once daily for 15 days, and the control group received routine orthodontic treatment without probiotics. GCF samples were collected from each participant at two time points: at the beginning of the treatment (T0) and on the 21st day (T1). Samples were obtained separately from all four canines using collection strips. The levels of IL-10 and TNF-alpha in GCF were analyzed using the enzyme-linked immunosorbent assay (ELISA) method. Statistical tests were performed to assess the normality of the distribution of quantitative variables. All analyses were performed using GraphPad Prism (version 9.1.1, GraphPad Software, San Diego, CA, USA). Data normality was assessed using the Kolmogorov-Smirnov test. Friedman's test for repeated measures was employed, followed by Dunn's post hoc test. ResultsThe variability that was observed for the IL-10 cytokine levels in the control group was significantly higher than that for the test group (p < 0.05). IL-10 levels in the test group increased while the TNF-alpha levels decreased. T1/T0 ratio for TNF-alpha was found to be lower in the test group compared to the control group (p = 0.002). ConclusionThe results suggest that probiotic tablets may play a role in modulating IL-10 and TNF-alpha levels during orthodontic tooth movement. However, the current study was limited to the first 21 days of mechanical force application to the teeth, and it is recommended to investigate the long-term effects or other factors affecting cytokine changes in future studies.
