Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 35 or older with clinical gingivitis or periodontitis, at least 10 natural teeth, stable general health, and the ability to provide informed consent.
✕Probably not a fit
People with unstable systemic or acute oral disease, those currently receiving specialized periodontal treatment, or those already using other periodontal therapies are unlikely to benefit from this intervention.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This interventional study gives an oral-spray probiotic containing Bacillus subtilis ANA48 and Bacillus clausii ANA39 or a saline control directly into the mouth of adult participants with gingivitis or periodontitis. Participants must have at least 10 natural teeth and be in stable general health. Outcomes include safety, changes in pathogenic bacterial density in the oral biofilm, and clinical signs of periodontal inflammation. The study is conducted at a senior care center in Hanoi with oversight from local academic collaborators.
Why it matters
Potential benefit: If successful, the spray could reduce pathogenic oral bacteria and inflammation, helping to prevent or better control periodontal disease in older adults.
How similar studies have gone: Other oral probiotic studies have shown modest benefits as an adjunct for periodontal disease, but Bacillus spore-based oral sprays are a relatively new and less-studied approach.
