About 7.8 percent of those adults have severe periodontitis.

The numbers come as part of the issue's cover story, "Periodontitis in U.S. Adults: National Health and Nutrition Examination Survey 2009-2014," in which researchers examined information from the National Health and Nutrition Examination Survey, which included data related to a full-mouth periodontal examination.

"This national study demonstrates that periodontitis is a highly prevalent oral disease among U.S. adults," said corresponding author of the study, Paul Eke, Ph.D., a senior health scientist and epidemiologist at the Centers for Disease Control and Prevention.
Dental practitioners "should be aware of the high prevalence of periodontitis in U.S. adults and may provide preventive care and counseling for periodontitis. General dentists who encounter patients with periodontitis may refer these patients to see a periodontist for specialty care," said Dr. Eke.
