Does Periodontal Treatment in Patients with Diabetes Lower Blood Sugar Levels?

May 13, 2010

The Cochrane Oral Health Group recently published Treatment of periodontal disease for glycaemic control in people with diabetes, a systematic review examining the relationship  between periodontal treatment and glycaemic control in diabetics.

The review, which included 7 Randomized Controlled Trials concluded there is evidence of improvement in metabolic control in people with diabetes, after treating periodontal disease.

For more detail, read the full review or listen to the podcast.

Does Treating Gum Disease Reduce the Incidence of Preterm Birth?

February 4, 2009

Previous research has suggested a link between periodontal disease and premature birth.  Consequently, pregnant woman have been encouraged to undergo periodontal treatment to reduce these risks.

However, recent studies conducted at the Univeristy of North Carolina’s School of Dentistry revealed no significant differences in pregnancy outcomes when study participants received treatment, as compared to those participants who did not.

As a result of these findings, the American Academy of Periodontology (AAP) released a statement calling for additional research to “clarify the potential impact that periodontal disease has on the risk of preterm births“.  The AAP also continues to encourage pregnant women to care for their oral health.

Periodontitis/Diabetes Link

July 2, 2008

Evidence of the link between periodontal disease and diabetes continues to grow, as indicated in a recent article by Robert Finn of Elsevier’s Global Medical News. Diabetes appears to induce periodontal disease or cause it to worsen in some patients, but periodontal disease seems to worsen glycemic control.

Evidence to support this conclusion stems in part from the “Scottsdale Project”.  The project consisted of 18 physicians, dentists, and other independent experts who met in Scottsdale, Arizona in April 2007 to review the strength of evidence for associations among periodontitis, diabetes, and cardiovascular disease. Participants conducted a systematic review of 118 published articles in an attempt to answer eight focused questions. 

Other data comes from analyses of the third National Health and Nutrition Examination Survey.

Information on the connection between periodontits and systemic diseases was also discussed in an earlier post on this blog.

Relationship Between Periodontal Disease and Chronic Diseases

June 17, 2008

The association between periodontal diseases and systemic conditions such as heart disease and stroke, and a higher risk of preterm low birth-weight babies, is garnering attention in the media. Similarly, recognition of the threats posed by periodontal diseases to patients with chronic diseases such as diabetes, respiratory diseases and osteoporosis is acknowledged.

The following are some links to recent stories and resources on these topics:

Periodontal Disease and Systemic Health

April 30, 2008

In January of 2008, the New York Academy of Science (NYAC) hosted From Basic Science to Clinical Practice and Policy: A Medical-Dental Dialogue on the Relationship between Periodontal Disease and Systemic Health.  The event was a continuing medical education activity also organized by the College of Physicians & Surgeons, Columbia University, and the National Periodontal Disease Coalition.

A full report of the meeting may be read here.

Presentations from this conference may be viewed by selecting the title on this page.  Topics include periodontits and vascular disease, preterm birth, kidney disease, renal disease and more.

NYAC has also provided an overview, meeting abstracts, information on the presenters, and other resources as part of it’s e-briefing.

Cannabis Smoking Increases Risk of Periodontal Disease

April 11, 2008

Tobacco smoking has been a known risk factor for periodontitis but it was uncertain whether or not cannabis use was harmful.  Essential Evidence Plus reviews a recent cohort study, published in the Journal of the American Medical Association, which concluded that regular marijuana smoking increases the risk of periodontal disease and subsequent loss of teeth.
