Demonstrates a long-lasting clinical improvement in chronic periodontitis by L. reuteri Prodentis lozenges as adjuvant to initial non-surgical periodontal therapy

Results

  • At all time-points from day 21 until day 360, L. reuteri Prodentis was significantly better than placebo (p<0.05) in terms of gingival index, plaque index, bleeding on probing and pocket depth.
  • Recolonization of pathogenic bacteria was significantly more delayed in the active group compared to placebo at days 21, 90, and 180 (p<0.05).
  • In the active group, significantly fewer patients required surgery of ≥3 sites.
BioGaia - Sites in need of surgery

Conclusion

L. reuteri Prodentis lozenges was a useful adjuvant agent to delay recolonization and improve clinical outcomes of chronic periodontitis.

Facts

  • Study design: randomized, double blind, placebo-controlled clinical trial
  • Subjects: 40 adults with chronic periodontitis and horizontal bone loss, and treated with scaling and root planing (SRP)
  • Dosage: 1 lozenge twice daily (4 x 108 CFU/day)
  • Duration: 3-week intervention, with evaluation at days 21, 90, 180, 360
  • Primary endpoint: reduction in pocket depth
  • Secondary endpoint: patients in need of surgery defined as PD ≥6 mm, or 5 mm and bleeding on probing
