Study Links Periodontal Disease, Cognition

Tooth Loss, Cavities, Gingivitis, Periodontal Disease All Linked to Lower Process of Thought

Study Links Periodontal Disease, Cognition

Researchers at Boston University Henry M. Goldman School of Dental Medicine (GSDM) released a definitive link between tooth loss/periodontal disease to cognitive decline in one of the largest and longest prospective studies on the topic to date, released in this month’s issue of the Journal of the American Geriatrics Society.

In what could be called ground-breaking research in the fields of dementia and Alzheimer’s, Dr. Elizabeth Krall Kaye looked for patterns in dental records from 1970 to 1973 to determine if periodontal disease and tooth loss predicted whether people did well or poorly on cognitive tests. She found that for each tooth lost per decade, the risk of doing poorly increased approximately eight to 10 percent.

More cavities usually meant lower cognition – or the process of thought – too. People with no tooth loss tended to do better on the tests.

Dr. Kaye suggests that doctors whose patients are testing poorly for cognitive standards may want to consider dental health. “The findings should also give dentists yet another reason to prevent tooth loss and periodontal disease and encourage patients to do as much as they can to prevent dental disease,” she explained.

With both periodontal disease and dementia/Alzheimer’s incidence rising sharply as Baby Boomers age, these findings could change the future of the hundreds of thousands of people predicted to develop Alzheimer’s and dementia in the next several decades.
