probiotic lozenges for treatment of recurrent aphthous stomatitis

Conditions: Oral Ulcer

Summary: the application of host-modulating bacteria for therapeutic purposes is one of the strongest emerging fields. probiotics are live microorganisms, which, when administered in an adequate amount, confer a health benefit on the host the study aimed to explore the effectiveness of probiotics in the treatment of the common ulcerative condition; minor recurrent aphthous stomatitis (ras). we included sixty adult (group a) and 60 children patients (group b) with diagnosis of minor ras . both groups were divided into two subgroups, ai and bi (test subgroups ) and aii and bii (control subgroups). for test subgroups, probiotic lozenges were consecutively administered twice daily, for five days. the size and pain level of ulcers were recorded on treatment days 0, 3 and 5. the outbreak frequency of ras within 6 months was investigated for all subgroups.

the study aimed to explore the effectiveness of probiotics in the treatment of minor recurrent aphthous stomatitis (ras). we performed a randomized, controlled clinical study. sixty adult (group a) and 60 children patients (group b) with diagnosis of minor ras were included. both groups were divided into two subgroups, ai and bi (test subgroups) and aii and bii (control subgroups). for test subgroups, probiotic lozenges were consecutively administered twice daily, for five days. the size and pain level of ulcers were recorded on treatment days 0, 3 and 5. the outbreak frequency of ras within 6 months was investigated for all subgroups. compared to baseline, an improvement was evident for all subgroups. however, for effectiveness in pain reduction, a statistically significant difference in favor of ai was observed for all evaluation periods when compared to control subgroup. regarding effectiveness in ulcer size reduction, a statistically significant difference in favor of bi was observed at day 5 when compared to control subgroup. no significant difference was observed in the effectiveness index between subgroups ai and bi (test subgroups) except in effectiveness in pain reduction at day 3. the outbreak frequency decreased significantly in subgroup bi. we concluded that topical application of probiotics decreased pain intensity and accelerate ras healing. the effectiveness in pain reduction is more evident in adult patients while acceleration of healing is more evident in children. probiotics could be a well-tolerated, topical therapeutic agent in the treatment of minor ras
