Periodontal Disease: A Quick Overview The AAP estimates that 3 out of 4 Americans are affected by periodontal disease, ranging from mild gingivitis to more severe periodontitis. Gingivitis is the mildest form of periodontal disease. It causes gums to turn red, become swollen, and bleed easily. Fortunately, it is easily reversible with good oral home care. If left untreated, gingivitis may advance to periodontitis. 3

Periodontal Disease, Cont. Periodontitis is the more advanced form of gum disease. The tissues and bone that support the teeth are broken down and destroyed, resulting in loosened teeth that may need to be removed There is an increased risk for other body problems. There are many treatment options available, including non-surgical and surgical therapies. 4

Periodontal Disease, Cont. However, the periodontal disease of yesterday is not the periodontal disease of today. Yesterday: researchers believed that gum loss in periodontal disease was caused by the bacteria in plaque. Today: researchers have determined that the gum loss in periodontal disease is caused by the inflammatory response to the bacteria in plaque. 5

What is Inflammation? Inflammation is the body’s first response to an injury. The first phase (acute inflammation) includes redness, swelling, heat, and altered function. It is self-perpetuating. There are several biological markers of inflammation in your blood, including C-reactive protein (CRP). CRP is a protein found in the blood which can rise in response to inflammation. Acute inflammation often causes elevated C-reactive protein. Elevated CRP is a risk factor for several chronic inflammatory diseases. Inflammation appears to be a common link between several common diseases of aging. These diseases include heart disease, arthritis, and periodontitis. 6

Inflammation’s Objective Inflammation tries to contain the injury to the local site. The body’s reaction is immediate (called the innate response). Its ultimate purpose is to protect the body from further damage. 8

Inflammation is Damaging when Uncontrolled Though inflammation can be helpful under certain conditions, uncontrolled inflammation, also called chronic inflammation, is harmful and causes tissue loss. Chronic inflammation occurs when there is a sustained infection, like periodontitis. Chronic inflammation involves more inflammatory mediators than the immediate innate response. 9

Chronic Inflammation Chronic inflammation can negatively affect all organs and tissues of the body.

Chronic Inflammation Chronic inflammation can negatively affect all organs and tissues of the body. Chronic diseases of aging are connected through common chronic inflammatory mechanisms. 10

Periodontal Paradigm Shift: Because of this new focus on inflammation, there has been a shift in the way periodontists view periodontal disease and its relationship to other disease states. 11

Periodontitis is a Chronic Inflammatory Disease of Aging Periodontitis involves a microbial challenge to

Periodontitis is a Chronic Inflammatory Disease of Aging Periodontitis involves a microbial challenge to the gums which stimulates an inflammatory response. Genetic and acquired risk factors lead to the host’s immuno-inflammatory response. A prolonged immuno-inflammatory response leads to destruction of connective and bone tissues, which leads to the possible loss of teeth. Chronic inflammatory diseases, such as periodontitis, arise over decades. Periodontal disease is a significant contributor to the total inflammatory burden on your body and can adversely affect your systemic health. 12

“Inflammation and Periodontal Diseases: A Reappraisal” In January 2008 a workshop sponsored by the AAP brought together more than 80 leading experts: Periodontists, cardiologists, diabetologists, geneticists, gerontologists, inflammation researchers This was an opportunity to engage in collaborative thinking and brainstorming across many different fields - using inflammation as a common finding. 13

Workshop, cont. The workshop was developed to expand advance our understanding of inflammation and the role it plays in diseases of aging. The experts from the diverse fields addressed topics of inflammation: What is inflammation? What specific mechanisms constitute inflammation? What factors regulate inflammation? Why do individuals have different expression levels of inflammation? Is the inflammation in one disease common to the inflammation in other diseases? 14

Workshop, cont. The experts engaged in discussion of the future of inflammation therapies and how they may change the future of periodontics. Proceedings from the Workshop were published in a supplement to the Journal of Periodontology in August 2008. (Available for free at: http: //www. joponline. org/toc/jop/79/8 s) 15

Workshop, cont. What we learned: Periodontal disease is a bacterially-induced chronic inflammatory disease that does not resolve by itself. The inflammatory response is important. Environmental and genetic factors affect expression of inflammation in individuals. The initiation and resolution of inflammation are well controlled processes. Diabetes, CVD, and stroke all share common inflammatory processes similar to periodontal inflammation. Resolution of any inflammation in the body is helpful for overall health. 16

AJC-JOP Consensus Paper The American Journal of Cardiology contacted the AAP after reading the August 2008 Journal of Periodontology supplement from the Workshop on Inflammation. A consensus paper was developed in collaboration with the American Academy of Periodontology and top cardiologists. The paper was published simultaneously in the Journal of Periodontology and the American Journal of Cardiology in June 2009. 21

AJC-JOP Consensus Paper, cont. The consensus paper is a summary of research that shows a connection between periodontal disease and CVD. It explains the underlying biologic and inflammatory mechanisms that may be the basis for the connection. Clinical recommendations for treating patients with cardiovascular disease and periodontal disease are also included. 22

CVD-PD Clinical Recommendations Examples of the clinical recommendations: Dentists are asked to consider their patients’ heart health and risk for CVD. Physicians are asked to consider their patients’ periodontal health and risk for periodontal disease. All health professionals are asked to educate patients on chronic inflammatory diseases and how they are related. Health professionals are also asked to work together to ensure patients are in best health. 23

The Relationship of Periodontal Disease to Other Inflammatory Diseases Inflammation appears to be the basis for the association between oral and systemic disease. One chronic inflammatory disease potentially influences the expression of other diseases: Tissue destruction is caused by prolonged inflammation. Moderate/severe periodontitis increases systemic inflammation. Systemic inflammation is associated with most chronic diseases of aging. For example, periodontal disease influences diabetes and diabetes influences periodontal disease. 24

Periodontists have three or more years of additional specialized training after dental school. It is important to refer a patient to an expert in the treatment of periodontal disease (a periodontist) if the inflammation is not resolved with regular teeth cleanings. 34

How to Reduce Inflammation: What does this mean for patients? Stop smoking. Reduce direct sources of inflammation: Visceral fat Exercise Reduce calories Chronic infections Periodontists can help reduce inflammation in the oral cavity. Activate inflammation resolution systems: Add Omega-3 fatty acids to your diet. Take a daily low-dose aspirin. Have your teeth professionally examined and cleaned regularly. 37
