The results suggest that periodontal therapy may reduce a diabetic patient's HbA1c count by as much as 20 percent at three and six months following treatment. According to the American Diabetes Association, HbA1c provides patients with a picture of their average blood sugar changes in the past two to three months and gives them a good idea of how well their diabetes treatment plan is working. A healthy HbA1c count is between the ranges of 4.0 to 6.0.
"We found that conventional treatment for chronic moderate generalized periodontitis, which included a simple, non-surgical procedure called Scaling and Root Planing (SRP) lowered the study group's HbA1c count from 7.2 to 5.7," said study authors Prof. Antonio Bascones and Dr.Ricardo Faria- Almeida from Department of Medicine and Buccofacial Surgery of the Complutense University in Madrid Spain.
"This could significantly put diabetic patients who are just above the normal HbA1c range into the healthy range and reduce their risk of serious complications from diabetes."
Bascones cautioned that these findings should not be considered definitive or universally generalizable because of the study sample size. In addition, this study compared the response to conventional periodontal treatment between type 2 diabetic and non-diabetic patients with chronic moderate generalized periodontitis and did not include a group of diabetics that was not undergoing periodontal treatment. The absence of this information is a limitation because it is not known how diabetic patients who were not undergoing periodontal treatment would have progressed.
"For a long time we've know that diabetic patients have a higher risk of developing periodontal disease compared to non-diabetics," said
