Teeth bacteria study in seniors with and without Alzheimer’s
Part of Brain & nervous system, Mental health, Mouth & dental clinical trials.
This study looks at the bacteria in the mouth (periodontal microbiota) to see whether they differ between seniors with Alzheimer’s disease and seniors without it. You may be asked for a sample from your gums/teeth and background health information.

This trial studies whether treating periodontal (gum) disease can help people who have probable Alzheimer’s disease. You may take a study treatment and have regular checks by a caregiver and study team.
This trial tests whether treating gum disease can improve outcomes for people with Alzheimer's disease. If you have mild to moderate Alzheimer's and gum disease, you may be able to join.
This trial tests a new medication, LHP588, for people with Alzheimer's who also have a common mouth bacteria called P. gingivalis. The goal is to see if targeting this bacteria can help slow down memory loss.
This study examines specific bacteria in your mouth to understand their role in healthy gums versus gum disease. Researchers will collect samples to measure bacterial levels and help improve how gum disease is diagnosed and treated.
This study tests whether a commercial toothpaste can reduce harmful bacteria in your mouth. It's for people with good general health who get regular dental cleanings and have a specific type of bacteria linked to gum disease.
This study tests whether bringing dental care to nursing home residents can reduce mouth infections, pneumonia, and help control blood sugar in people with diabetes. If you live in a nursing home and are 60 or older, you may be able to join.
