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.

How Does Diabetes Affect Oral Health?

November 2, 2009

The American Diabetes Association has designated November as American Diabetes Month. Diabetes can lead to complications such as heart disease, stroke, kidney disease, blindness, and oral health problems.

In recognition of  American Diabetes Month, we suggest you update your knowledge of the connection between oral health and diabetes.  This  connection is covered in both the medical and dental literature.  The American Diabetes Association has also published an overview of oral health problems for diabetic patients.

In addition, Bibby library has created a list of internet resources including links to review articles and information for patients.

Update November 3, 2009: The American Academy of Periodontology has released a statement in support of the International Diabetes Foundation’s  guideline on oral health for people with diabetes.

Oral Health: The Public Speaks

October 20, 2008

The American Dental Association, in collaboration with Crest and Oral-,B conducted a national public opinion survey on oral health care.  The survey represented  1,000 Americans ages 18 and older, living in the continental United States. The survey focused on the following areas:

  • The public’s perceptions of their oral health care, with a special focus on African Americans, Hispanics and lower-income Americans
  • Americans’ knowledge of effective and essential oral health care habits
  • Oral health habits among the nation’s youth
  • The psychological benefits of a healthy smile

Key findings include:

  • Eight out of  ten Americans say taking care of one’s mouth, teeth and gums is “absolutely needed; however, only one-third of them say they do an “excellent” job taking care of them
  • One out of four parents describe their children’s job of taking care of their oral health as fair” or “poor”

More than one in three Americans say:

  • They think a little bleeding from brushing is normal (33%)
  • They are unaware that periodontal disease needs to be treated and cannot be left alone (33%)
  • They don’t know that poor oral health has been associated with serious health conditions such as stroke, heart disease  and diabetes (37%)

The full report and related documents are available on the ADA site.

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.

Read the full article, which contains additional resources, here.

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:
