Non-surgical dental care and oral hygiene to lower risk of infective endocarditis
Randomized Trial of non-Surgical Therapy and Oral Hygiene Instruction to Reduce Risk of Infective Endocarditis
This project tests whether professional dental cleanings plus clear home oral hygiene instruction can reduce the mouth bacteria that enter the bloodstream and may cause heart valve infections in people with certain heart conditions.

What this research studies
You would be randomly assigned to receive non-surgical dental care (such as professional scaling) and tailored oral hygiene instruction or usual care, and dental plaque and gum health would be tracked over time. Researchers will take blood samples around routine activities like toothbrushing to count and identify bacteria that enter the bloodstream. The team will compare how often and how long bacteremia occurs between the groups and relate that to plaque and gum inflammation. The goal is to see whether better dental cleaning and home care lower the bloodstream bacteria linked to infective endocarditis.
Who could benefit from this research
Good fit: People with pre-existing heart valve disease or other conditions that put them at increased risk for infective endocarditis are the ideal candidates.
Not a fit: People without heart valve disease or other IE risk factors, or those who already maintain excellent oral health, are unlikely to gain direct benefit from this trial.
Why it matters
Potential benefit: If successful, this approach could lower the chance that ordinary mouth bacteria enter the blood and seed heart valves, potentially preventing dangerous infective endocarditis in at-risk patients.
How similar studies have performed: Prior work shows toothbrushing and poor oral hygiene can cause bacteremia and that people with IE have more plaque, but there have been no prior randomized trials proving improved oral hygiene reduces bacteremia or IE risk.
