Patients with diabetes who are treated for periodontal disease are less likely to see a physician and less likely to be hospitalized. Furthermore, they cost the healthcare system $1800 less per patient per year….
Lead investigator Marjorie Jeffcoat, DMD, professor of periodontics at the University of Pennsylvania, Philadelphia noted that, “The biggest surprise was the tremendous decrease in doctor visits.”
Dr. Jeffcoat and her colleagues looked at data from patients who had Highmark medical insurance and United Concordia dental insurance. The researchers identified 91,454 patients with diabetes, making this study the largest in a series suggesting that periodontal care can improve the health of these patients.
From this group of diabetic patients, the investigators analyzed 773 patients who chose to have periodontal treatment and 60,706 who chose not to have periodontal treatment (control group). Both groups were covered by dental and medical insurance. There was a 33% reduction in the number of hospitalizations with treatment; the mean number of hospitalizations was 5.9 in the treatment group and 9.0 in the control group (P < .02).
There was a 13% reduction in the number of physician visits with treatment; the mean number of visits was 16.4 in the treatment group and 19.0 in the control group (P < .0001). There was a savings of $1814 (or 25%) with treatment; mean medical cost was $5522 in the treatment group and $7336 per year in the control group (P < .05).
Dr. Jeffcoat stated that, “The other thing that was a big surprise was that the effect was maintained over a 3-year period,” and the savings in medical costs increased while the difference in doctor visits and hospitalizations diminished over the 3 years.
A large number of the patients had other health conditions, such as cardiovascular disease. In the future, Dr. Jeffcoat and her colleagues hope to study the data on these patients to see whether a similar link can be found between periodontal treatment and these diseases.
