Are probiotics a possible treatment of periodontitis? Probiotics against periodontal disease: a systematic review

# metadata.dc.description.abstract[].value
Introduction: Periodontal disease is one of the most prevalent oral diseases. Until now, periodontal disease treatments offer good results but periodontal pockets can be immediately recolonised by pathogenic bacteria. The limitations of these treatments have led to the need to find more effective alternatives that reinforce the periodontal treatments. Aim: To evaluate the clinical effect of probiotics as an adjuvant treatment to scaling and root planing in patients with periodontitis. Materials and methods: An electronic search in Medline (via PubMed) of randomised clinical trials published in the last ten years that include the effects of using probiotics in periodontal disease was performed. Results In total, ten trials were included and in seven of them the evaluated clinical parameters were significantly improved in the test group compared to the placebo group. In five trials, a significant reduction of the main periodontal pathogens was reported. No side effects were observed in any trial. Conclusions The administration of probiotics as an adjuvant treatment to periodontal treatment helps improve the clinical parameters, significantly decreases the concentration of the main periodontal pathogens and does not cause any side effects.
