Self-awareness of "Gum Disease" Among US Adults

Background:
To assess the extent of self-awareness of gum disease among adults in the United States.
Methods:
Data were from the 2009-2012 National Health and Nutrition Examination Survey. The outcome variable is self-awareness of gum disease. Multivariate logistic regression models were used to examine the relationship between self-awareness and clinically diagnosed periodontitis. The analytical sample included 6876 participants.
Results:
Among those participants (30 years or older) who were classified as having periodontitis, 27% (95% confidence interval [CI], 24.4-29.8) were self-aware of the disease (positive predicted value = 25%). Of those who self-reported having gum disease, 14.1% had a diagnosis of periodontitis (sensitivity = 75%). Older adults were less likely to be aware of gum disease (P < .05). Non-Hispanic blacks (adjusted odds ratio [AOR] = 0.67; 95% CI, 0.53-0.85) were less likely to be aware of the disease than non-Hispanic whites. Adults with diabetes (AOR = 1.61; 95% CI, 1.25-2.06), or with lung disease (AOR = 1.61; 95% CI, 1.25-2.08), or current smokers (AOR = 1.72; 95% CI, 1.29-2.31) were more likely to be aware of the disease.
Conclusion:
The study showed that self-awareness of gum disease among adults was low. Our study findings suggest that there is a great need to improve oral health knowledge and awareness among the adult population in the United States.

Self-Awareness and Its Effects
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
