Abstract
Objective. To review relevant literature to determine if poor oral health is a risk factor for dementia.
Methods. Studies gathered from PubMed, CINAHL, and Google Scholar were reviewed for associations between poor oral health and dementia or pre-dementia markers.
Results. The studies in this review presented mixed results, but the prevailing finding was that patients with poor oral health are at an increased risk of developing dementia, compared to those who have better oral health. However, not all of the studies had statistically significant results.
Discussion. The studies suggest that oral health may be a modifiable risk factor for dementia. This is promising because oral health is something that is relatively easy and inexpensive to monitor and maintain. Dental professionals should use the evidence presented in this study to encourage patients to practice good oral hygiene and to come in for regular cleanings and examinations.
