ANN ARBOR, Mich.---University of Michigan School of Dentistry has signed an agreement with Interleukin Genetics Inc. to conduct what may be the largest clinical study to date using genetic testing to assess the risk for gum disease.
William Giannobile, professor at U-M dentistry and director of the Michigan Center for Oral Health Research at the School of Dentistry, will lead the study for U-M.
"It's an exciting study because it's a way to use genetic testing to personalize a dental treatment plan and the frequency of dental care visits of patients as it relates to oral care," said Giannobile. "It's a way to customize patient care."
"One of the goals of personalized health care is to detect disease earlier and prevent it more effectively," said Kenneth Kornman, president and chief scientific officer of Waltham, Mass. based-Interleukin. The study will use Interleukin's PST test as one part of a periodontitis risk assessment, said Kornman, who is also an alumnus of the U-M Dental School. Research has shown that genetics plays a large role in gum disease, and research also suggests that severe gum disease is a risk factor for other chronic disease complications such as heart disease or low birth weight.
U-M scientists will examine 15 years of patient clinical outcome data provided by a Michigan-based insurance company. Scientists will then recruit at least 4,000 of those patients and get their genetic information using the PST, Giannobile said.
They will combine this genetic information with two other common risk factors, smoking and diabetes, then measure tooth survival rates to see how those results lined up with the treatment plans people received over the 15 years. Some patients may have needed more dental visits, some may have required less, Giannobile said.
The PST genetic test works by identifying genetic variations that are predictive of severe gum disease and tooth loss in some patients. The t
