WALTHAM, Mass.--(BUSINESS WIRE)--Interleukin Genetics, Inc. (OTCQB: ILIU) announced today that the Company has received top line results from the Periodontal Disease Prevention Study (PDPS) being conducted by the University of Michigan School of Dentistry. The preliminary results indicate that in Low Risk patients, there was no significant difference between two dental preventive visits per year and one preventive visit per year in reducing the percentage of patients who had tooth extractions over the 16 year monitoring period; 13.8% versus 16.4% (p=0.092 ns). In addition, results indicate that in High Risk patients, two preventive visits per year significantly reduced the percentage of patients who had extractions over a 16 year monitoring period compared to one preventive visit per year; 16.9% vs. 22.1% (p=0.002). There was also a positive relationship between number of risk factors and the percentage of patients with extractions (p<0.001). The Low Risk population (approximately 47% of the study) was defined as non-smokers, genetically negative per the Company’s PST test and no history of diabetes. High Risk patients were defined as having one or more risk factors, i.e. PST positive, diabetes or smoking.
