Abstract: Objective: To evaluate the clinical efficacy and oral microbiome composition of patients with recurrent aphthous ulcer treated with probiotic fermentation gel. Methods: A randomized double-blind design was designed to compare the days of ulcer healing between the experimental group and the control group. 35 RAU patients were selected and randomly divided into experimental group and control group. Probiotic aloe fermentation gel was applied locally in experimental group and chitosan gel was applied locally in control group. Saliva of RAU patient was collected before using medicine as PC group. The probiotics group (AA) and the control group (AC) were randomly divided into two groups. Saliva of the two groups was collected after treatment. Saliva from 10 healthy persons was used as negative control (NC group). The clinical treatment effect and oral microbiome composition were evaluated. Results: Probiotic fermentation gel had better wound healing effect (P<0.05). At phylum level: the relative abundance of Actinomycetes increased in the PC group, but decreased in the AA group. At genus level: the relative abundance of Haemophilus and Neisseria decreased, but the relative abundance of Actinomycetes, Granulococcus, and Streptococcus Gastric increased in the PC grou; and the relative abundance was normal in the AA group. Conclusion: Probiotic fermentation can accelerate ulcer healing and normalized microbiota disorders of RAU.
