Brief Summary:

Aim: to evaluate the additional effects of the 12 weeks usage of a Streptococcus containing probiotic tablet after scaling and rootplaning compared to a placebo tablet.

Materials and methods: 48 periodontitis patients were included in this double-blind, placebo-controlled trial. After scaling and rootplaning, they were given patients used either a placebo (SRP) or probiotic tablet (SRP + P), 2 times a day for 12 weeks. Clinical and microbiological parameters were studied recorded up to 24 weeks after scaling and rootplaning.
