Objectives:
This pilot study examined the association between food insecurity and edentulism among older adults in Washington State.
Methods:
This study focused on adults aged 50 years and older, who were recruited through seven community-based organizations in Washington State. The exposure variable was food security level (high, marginal, and low/very low food security) assessed using the 10-item U.S. Adult Food Security Survey. The outcome was edentulism, defined as having zero natural teeth. Confounder-adjusted odds ratios (OR) and 95% confidence intervals (CIs) were generated using binary logistic regression models (α = 0.05).
Results:
Of the 216 participants, 28.7% (n = 62) had low/very low food security and 7.9% (n = 17) had zero teeth. Older adults with low or very low food security had greater odds of being edentulous compared to those with marginal or high food security, although the difference was not statistically significant (OR: 1.39; 95% CI: 0.46, 4.20; p = 0.56).
Conclusions:
Future research should explore food insecurity-focused interventions aimed at preventing edentulism in older adults in a broader effort to address oral health inequities.

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...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
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...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
