Understanding the Link Between Periodontitis and Brain Function in Older Adults

A recent study published in the Journal of Periodontology has unveiled concerning evidence about the impact of periodontitis aka gum disease on brain function in middle-aged and elderly individuals. Conducted by researchers from Anhui Medical University examined the brain activity of 51 participants with varying degrees of gum disease.

Let’s break down the top takeaways from the study:

1. Finding: Altered Brain Network Connectivity in Moderate-to-Severe Gum Disease

The study identified significant changes in both intranetwork and internetwork functional connectivity in individuals with moderate-to-severe periodontitis. Notably, there was increased connectivity between the systems within the brain among those with less severe gum disease.  Conversely, those who had more advanced periodontitis, showed decreased connectivity within the brain.

2. Finding: Brain Function Impairment Despite Normal Cognition

Even in the absence of cognitive decline in the study participants, individuals with moderate-to-severe periodontitis exhibited altered brain network function. This suggests that periodontal disease may contribute to subtle neurological changes that precede overt cognitive impairments.  Gum disease acts as a precursor to other diseases associated with aging.


3. Finding: Correlation Between Your Gum Health and Brain Connectivity

The study found a significant correlation between the severity of periodontitis, as indicated by the periodontal clinical index, and the observed changes in brain network connectivity. This underscores the potential of periodontal health as a modifiable risk factor for brain function.

4. Finding: There's Potential Implications for Alzheimer's Disease Prevention

The alterations in brain connectivity associated with periodontitis, even in cognitively normal individuals, may serve as early indicators of neurodegenerative processes. This highlights the importance of early periodontal intervention as a preventive measure against conditions like Alzheimer's disease.

5. Finding: Advocating for Comprehensive Healthcare Approaches

The findings advocate for an integrated healthcare approach that considers oral health as a critical component of overall well-being. Regular dental check-ups and periodontal care should be emphasized, especially for middle-aged and elderly populations, to mitigate potential risks to brain health.

Final Thoughts

This study provides compelling evidence linking periodontitis to alterations in brain network connectivity, even in individuals without cognitive impairments. These findings underscore the importance of maintaining optimal oral health as a proactive strategy to preserve brain function and potentially delay the onset of neurodegenerative diseases like Alzheimer's Disease.  For many years the medical community did not see the value or connection between overall health and dental health, but those days are behind us as new data continues to emerge indicating a clear connection.

Periodontal Disease: Causes and Prevention

Periodontal Disease


What Is It?

Periodontitis is a term used to describe a group of conditions that involves inflammation of the gums and other structures that support the teeth. Periodontitis is caused by bacteria found in dental plaque and often, but not always, starts as gingivitis.

In trying to eliminate the bacterial infection, your body produces substances that destroy the structures that hold the teeth in the jaw, including the periodontal ligament and underlying bone. As this process continues, the teeth become loose. Pockets form between the teeth and gums, allowing more bacteria to accumulate. Left untreated, periodontitis can result in tooth loss.

Periodontitis usually is relatively painless. The onset of significant pain may signal the development of an abscess.

Older adults are more likely to have periodontitis.

People who smoke are four to seven times more likely than nonsmokers to get periodontitis. Smoking may impair the body's defense against bacteria.


Symptoms

Symptoms include:

  • Reddened, swollen or bleeding gums
  • Receding gums
  • Loose Teeth
  • Bad breath
  • An unpleasant taste in the mouth
However, many people are unaware of these symptoms or do not believe they are signs of a serious problem.


Diagnosis

Your Ventura dentist, Dr. Frank Esfandiari will examine your mouth, paying special attention to your gums and teeth. If you have periodontitis, a dental probeinserted between your tooth and your gums will penetrate deeper than it normally would.

Your dentist may also test for loose teeth. Teeth have a normal range of mobility, but in people with periodontitis, the teeth are looser due to the destruction of the fibers and bone supporting the teeth.

Your dentist may also order X-rays to help diagnose periodontitis. These can be compared with older X-rays to see if changes have occurred in your teeth and gums.


Expected Duration

Unlike gingivitis, periodontitis cannot be completely reversed. In some situations, the supporting fibers and bone that have been lost can be regenerated. In most cases, however, particularly in advanced stages of the disease, the effects are permanent. However, treatment and improved oral hygiene at any stage can improve the health of your gums and prevent further destruction.


Prevention

Daily brushing and flossing (morning and night) and regular visits for professional cleaning can help prevent periodontitis or allow you to have it treated during its earliest stages. If you smoke, quitting will reduce your risk significantly.


Treatment

Treatment depends on how severe your periodontitis is. Dentists classify the disease as mild, moderate or severe.

Mild periodontitis is usually treated first with a thorough cleaning called scaling and root planing. Scaling removes plaque or calculus that has accumulated on the crowns of your teeth (the parts that show) and slightly below the gum line. Root planing has two purposes: 1) to remove plaque or calculus from the roots of your teeth and 2) to smooth the roots of the teeth, making it more difficult for bacteria to cling to them. This, combined with good oral hygiene at home, often is enough for successful treatment.

Moderate periodontitis may require more than scaling and root planing. Typically, your dentist will scale and root-plane your teeth. If this does not take care of the problem, he or she may decide that you need surgical treatment. Surgery can involve reshaping the gums to fit the teeth (resective surgeries) or encouraging lost bone to regrow (regenerative surgeries). Your dentist will decide whether you will need surgery and what type you need.

Severe periodontitis likely will require surgical intervention and, in some instances, antibiotics. At this stage of disease, tooth loss is a distinct possibility.

No matter which treatment you undergo, you should start a strict regimen of brushing and flossing to help restore your teeth to health.


When To Call Your Ventura Dentist

The best course of action is to get regular dental checkups. If you have persistent bleeding or swelling of your gums or notice loose teeth, call your dentist.


Prognosis

The outlook is good if the disease is recognized early and treated aggressively. Once bone loss occurs, the prognosis depends on the severity of the loss. Quitting smoking is very important for periodontal therapy to be successful. Lifelong maintenance will be required once the disease is controlled.
