Summary

This study looks at whether taking a probiotic supplement called Prodentis for a long time after standard gum treatment can improve gum health and immune response. Twenty adults with advanced gum disease who have already had one round of treatment will be followed. Researchers will measure gum pocket depths and check immune markers in blood and saliva.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Prodentis (a probiotic dietary supplement)
What this could lead to
If it works, this could show that taking probiotics long-term helps control gum disease better than short-term use alone.
What could go wrong
This is a very small early-stage trial with only 20 participants, so results may not apply to everyone. Probiotics may not provide additional benefit over standard gum treatment.
