Effect of obesity on non-surgical periodontal care

Washington: A new study explores how the most common non-communicable diseases, Obesity and gum (periodontal) might be related to each other. It also highlights the effect of obesity on non-surgical periodontal care. The study was published in 'British Dental Journal.'

The connection between obesity and gum disease isn't as simple as cause-and-effect, said Andres Pinto, co-author of the study at the Case Western Reserve University School of Dental Medicine. Instead, the relationship centres on what both diseases have in common: inflammation.

Examining a large number of existing studies, researchers found that data showing increased body mass index, waist circumference and percentage of body fat to be associated with an increased risk to develop gum disease, also known as periodontitis.

Most studies analysed data from population subsets at one point in time, as opposed to studying the same population over a longer period. They concluded that changes in body chemistry affect metabolism, which, in turn, causes inflammation--something present in both maladies. "Periodontal disease occurs in patients more susceptible to inflammation--who are also more susceptible to obesity," Pinto said.

"This information can inform how health-care professionals plan treatments for patients suffering from obesity and/or gum disease." "Oral health-care professionals need to be aware of the complexity of obesity to counsel their patients about the importance of appropriate body weight and maintaining good oral hygiene," he added. Pinto said further research on the relationship between gum disease and obesity is needed, noting there is, at this point, limited evidence to recommend changes in treatment planning.

"There is a thought, from the clinical perspective, that if you treat one of the issues, it may impact the other," he said. "This is a big question. For example, if we treat obesity successfully, will this impact periodontal disease to the point of being of clinical relevance compared to control the population. The jury is still out given the paucity of controlled, well designed, clinical trials on this issue."
