To study the efficacy of local application of oral probiotics in improving oral health in recurrent aphthous ulcer and oral candidiasis. Eighty patients with diagnosis of recurrent aphthous ulcer and oral candidiasis were included in the study. They were divided into group A = 40 patients (patients treated with oral application of probiotic as an adjuvant) and group B = 40 patients (patients treated without probiotic). Both the groups were divided into two subgroups, group AU and group BU for recurrent aphthous ulcer and group AC and BC for oral candidiasis. Clinical signs and symptoms were assessed at the beginning of the study and at the end of the study. Pregnant or lactating women, patients with localised or systemic diseases such as Steven Johnson syndrome, ulcerative colitis, Behcet’s syndrome and patients on chemotherapy or radiotherapy were excluded from the study. Bacillus Clausii, was used as a probiotic in our study. Patients in group A showed significant improvement in erythema (p = 0.001), pain reduction (p = 0.0001), decreased oral thrush (p = 0.006) and burning sensation in the mouth (p = 0.005) on day 5, whereas there was no significant difference on day 10 follow up. The study demonstrated the efficacy and rapidity of response to oral probiotic as an adjuvant in treating aphthous ulcer and oral candidiasis. Hence, oral application of probiotics can be used as an adjuvant in treating various oral pathology.
