Losing fat may improve gums

November 10, 2011 - Washington

Losing extra pounds may help our body fights off gum disease, according to Case Western Reserve University School of Dental Medicine researchers.

They found the human body is better at fighting gum disease when fat cells, which trigger inflammation, disappear.

Findings come from a pilot study of 31 obese people with gum disease. Half of the group with an average Body Mass Index (BMI) of 39 had Gastric bypass surgery and had fat cells from the abdomen removed.

That half fared better than a control group of obese people with a BMI of 35 who also were treated for gum disease but did not have the Gastric bypass surgery or fat removed.

While both groups showed improvement, the surgery group did even better on the measures for periodontal attachment, bleeding, probing depths and plaque levels.

Inflammation that continues to brew in the body can have harmful effects over time, and inflammation from gum disease can erode bone and cause tooth loss. It can also cause breaks in the gums where harmful oral bacteria can enter the blood stream.

Such bacteria have been linked to preterm birth, fetal death, heart disease, Diabetes and arthritis, said Nabil Bissada, chair of the department of periodontics at Case Western Reserve School of Dental Medicine and lead author of the study.

The study has been published in the Journal of Periodontology.
