Medical Information Immediately: Diabetes: Take care of your enamel to take care of your blood glucose

A new study highlights the importance of oral hygiene for people with type 2 diabetes, after finding that those with the condition may have better blood glucose levels if they look after their teeth.

Researchers say that people with type 2 diabetes may improve their blood glucose levels by looking after their teeth.

It is estimated that around in the United States are living with . is the most common form, and it accounts for 90–95 percent of all cases.

Type 2 diabetes develops when the body‘s cells stop responding to the hormone. This is a process known as. Blood glucose levels become too high as a result.

Without effective management of blood glucose levels, a number of serious complications may arise, nerve damage, or, eye problems such as and, and skin conditions.

Previous research has also shown that there is a two-way link between type 2 diabetes and, or periodontitis; individuals with type 2 diabetes are at greater risk of developing gum disease, and gum disease may increase the risk of type 2 diabetes.

The — recently published in The Journal of Clinical Periodontology — suggests that for people who already have type 2 diabetes, good dental hygiene could be key for managing blood glucose levels.

‘Deep cleaning‘ improved HbA1c levels
Led by Miquel Viñas — a professor of microbiology at the University of Barcelona in Spain — the study included 90 adults who had an average hemoglobin A1c (HbA1c) level of 7.7 percent, constituting a diagnosis of type 2 diabetes.

The adults were randomized to one of two groups for 6 months. One of these groups received oral health instructions, as well as, a non-surgical form of “deep cleaning” that removes tartar and plaque from the surface of the teeth and below the gums.

The other group — the controls — received oral health instructions plus supragingival removal of plaque and tartar, meaning that plaque and tartar are removed from above the gum line only.

Both groups had their HbA1c levels, fasting plasma glucose, and oral bacteria levels measured at 3 and 6 months after the start of the study.

The results revealed that the group that received the deep cleaning experienced significant improvements in HbA1c levels and fasting plasma glucose, while the control group saw no improvements.

The team notes that, in most cases, these improvements corresponded with oral bacteria levels. has shown that oral bacteria may play an important role in diabetes.

So, it seems that good oral hygiene and regular dental checkups may aid good blood glucose management for people with type 2 diabetes.

“The main conclusion of the study is that the non-surgical treatment of improves the glycemic status and levels of glycated hemoglobin, and therefore proves the great importance of oral health in these patients.”
