Clinical Trial Summary

Gingival inflammation (gingivitis) is commonly reported in teenagers with fixed orthodontic devices (FOD). Indeed, FODs promote the accumulation of plaque and interfere with the efficacy of tooth brushing. According to in vitro and in vivo studies, the administration of oral probiotic bacteria including Lactobacillus reuteri may reduce the number of periodontal pathogens in saliva and dental plaque. A recent systematic review shows a positive effect of probiotics in addition to tooth brushing in the treatment of periodontitis. However, there is insufficient data regarding the effect of probiotics in the prevention of gum diseases. The aim of this double-blind randomized placebo-controlled study is to assess the effect of probiotics, in addition to dental brushing, on gum inflammation and the composition of the oral microbiota in teenagers with fixed orthodontic appliances
