New Study Published: Lactobacillus reuteri Prodentis Effective in the Treatment of Periodontitis

November 10, 2010

STOCKHOLM, November 10, 2010 /PRNewswire-FirstCall/ — The study shows
that L. reuteri Prodentis acts synergistically with standard treatment
(scaling and root plaining, SRP) to significantly reduce probing pocket depth
(PPD) and clinical attachment level (CAL) which are the two most important
parameters to assess the severity of periodontitis. Furthermore L. reuteri
Prodentis reveals – as the first probiotic ever – significant reductions of
three different pathogens in patients with chronic periodontitis. The study
also confirms the anti-inflammatory effects of L. reuteri Prodentis on gum
inflammation (gingivitis).

Chronic periodontitis occurs in up to 40 % of the adult population. The
standard treatment aims at removing plaque in the dental pockets to reduce
the periodontal pathogens and thereby prevent disease progression.

Thirty chronic periodontitis patients were included in the double blind,
randomized, placebo-controlled clinical trial that lasted for 42 days. On day
0 the teeth in one half of the mouth were treated with SRP whereas the teeth
in the other half were left untreated. From day 21 to day 42 the patients
were supplemented with either L. reuteri Prodentis lozenges (1X108 CFU DSM
17938 and 1×108 CFU ATCC PTA 5289) or placebo lozenges twice daily.

The result showed that a combination of L. reuteri Prodentis and SRP was
significantly better than all other modalities in reducing gingivitis and
plaque. Moreover, L. reuteri Prodentis, either alone or following SRP,
significantly reduced the pathogens Aggregibacter actinomycetemcomitans,
Porphyromonas gingivalis and Prevotella intermedia by up to 90 % as compared
to the treatments that did not include L. reuteri Prodentis. The combination
of L. reuteri Prodentis and SRP was also significantly better than SPR alone
in reducing both PPD (p<0.001) and CAL (p<0.001), see attachment.

    - This short-term study proves that L. reuteri Prodentis by itself has a
    powerful effect on the pathogens of periodontitis and that the
    combination of L. reuteri Prodentis and SRP synergistically improves
    both PPD and CAL, says Professor Vandana at the College of Dental
    Science in Davangere, India.

    - The results strengthen L. reuteri Prodentis position as a
    proven treatment option for patients with periodontal disease, says Peter
    Rothschild, President, BioGaia AB.
