Health Of Gums Improves With Weight Loss
Case Western Reserve University School of Dental Medicine researchers 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.
Obesity Link To Periodontitis
In a study titled "MicroRNA Modulation in Obesity and Periodontitis, " lead author Romina Perri, University of North Carolina School of Dentistry, Oral Health Institute, conducted a pilot investigation to determine whether obesity or periodontal disease modified microRNA expression and whether there was any potential interaction between obesity and periodontitis that could involve microRNA modulation. This study is published in the Journal of Dental Research, the official publication of the International and American Associations for Dental Research (IADR/AADR).
Mathematics Provides Better Attachment For Dental Crowns
Dental treatment involving crown replacements costs the Swedish tax payers hundreds of millions SEK each year. Researchers at Chalmers University of Technology are developing a new method for determining exactly how to optimally prepare a tooth to place a crown on it. The method is expected to result in significantly cheaper and faster treatment, and improved quality and reliability of the crown replacements. Each year, dentists put hundreds of thousands of new dental crowns into the mouths of Swedish patients.
