CDC Estimate New Mexico, Hawaii Have Highest US Incidence of Advanced Gum Disease

New data emphasises need for oral health literacy, access to care in largely affected regions


Chicago, IL, USA – In a new study published by the Journal of Dental Research, the Centres for Disease Control and Prevention (CDC) estimates that at 52.79 per cent and 51.10 per cent, respectively, New Mexico and Hawaii have the US highest prevalence of periodontitis.

The study titled “Predicting Periodontitis at State and Local Levels in the United States,” also indicates high prevalence among south-eastern and south-western states, including areas along the Mississippi Delta and the US-Mexico border. The states with the lowest prevalence include Utah (37.69 per cent) and New Hampshire (40.51 per cent).The areas estimated to have the greatest concentration of periodontitis directly correlate with regions that also see high incidence of cardiovascular disease and diabetes, systemic conditions often associated with periodontitis.

Additionally, the latest findings are in line with early CDC reports that periodontitis disproportionately affects ethnic minorities, tobacco users, those of lower socio-economic status, and those in areas with sparse access to dental care.

“This is the first study to model the distribution of adult periodontitis in states and local areas in the US,” says Dr. Paul Eke, CDC epidemiologist and lead author of the study. Dr. Eke goes on to say, “We found the estimated geographic distribution of adult periodontitis to be highest among south-eastern and south-western states, with concentrated pockets along the southeast, in the Mississippi Delta, along the US-Mexico border, and among Native American reservations. Given how closely associated the risk for periodontitis is with other chronic conditions, such as diabetes or cardiovascular disease, the prevention and treatment of periodontitis represents an opportunity for dental and medical professionals to work together to improve the public’s health.”

The figures are the latest reported by the CDC to determine the burden on periodontitis on the US adult population. The American Academy of Periodontology (AAP) and the CDC, which have collaborated since 2003 to determine periodontitis prevalence, have found that nearly half of all US adults age 30 and above have some form of periodontal disease.

“Periodontal disease continues to be a major health concern for people of all backgrounds,” says Dr. Wayne Aldredge, president of the AAP. “The AAP is committed to increasing public awareness of periodontal health and will continue to work with allied dental organisations, educational institutions, and government agencies to reduce incidence of periodontitis in the US adult population.”

Periodontal disease is caused by an inflammatory reaction to a bacterial infection below the gum line, and it can lead to swelling, irritation, receding gums, and tooth loss if left untreated. The AAP recommends regular flossing, brushing twice a day and undergoing yearly comprehensive periodontal evaluations for the prevention of periodontal disease, which is treatable and often reversible with proper and timely care from a periodontist.

“Individuals who do not have a periodontist but suspect they may have gum disease should schedule an appointment with a general dentist in their area,” Dr. Aldredge says. “General dentists can provide a referral to a nearby periodontist if disease is present.”
