{Abstract}: We aimed to assess the therapeutic effects of a topical probiotic nano-formulation derived from Lactobacillus reuteri on treating recurrent aphthous stomatitis.<BR>60 participants were randomly allocated into two groups (control and probiotic). Probiotic group administered topical probiotic nano-formulation three times a day for seven days. The control group administered a standard analgesic oral rinse. The size of ulcer(s) and pain severity were recorded on days 0, 3, 5, and 7 after intervention.<BR>Before the intervention, the groups had no significant differences in terms of pain severity (P-value = 0.28) and lesion size (P-value = 0.24). Both groups exhibited significant reductions in pain severity and lesion size over the course of the intervention. After one week, the probiotic group had a notably larger lesion size reduction than the control group (P-value = 0.01). The probiotic group also showed a significantly greater reduction in pain severity than the control group (P-value = 0.04).<BR>Applying topical probiotic nano-formulation derived from Lactobacillus reuteri three times a day decreased lesion size and pain severity in RAS patients faster than the local analgesic oral rinse.<BR>Lactobacillus reuteri-derived probiotic nano-formulation might be a promising treatment option for RAS.
