Clinical and Microbiological Effects of Lactobacillus Rhamnosus in Treatment of Gingivitis

The aim of this randomized placebo- controlled clinical trial is to evaluate the effects of Lactobacillus rhamnosus SP1- containing probiotic sachet as an adjunct to scaling and root planning (SRP). Material and methods: Thirty six gingivitis patients will be recruited and monitored clinically and microbiologically at baseline and 3-6 months after therapy. All patients will receive scaling and periodontal treatment and randomly will be assigned over an experimental (SRP + probiotic, n=18) or control (SRP + placebo, n=18) group. The sachet will be used once per day during 3 months.
