Objectives:
To evaluate the relationships of cognitive function and care dependency with oral health in a Norwegian older adult population.
Methods:
This cross-sectional study included 2623 participants aged 70 and older from the fourth wave of the Trøndelag health study (HUNT4 70+) and the city of Trondheim (Trondheim 70+). Neurocognitive disorders (NCDs) were diagnosed by clinical experts according to the DSM-5 framework. Care dependency referred to nursing home residency. Oral health was assessed by using the Revised Oral Assessment Guide-Jönköping (ROAG-J). Individuals were considered as 'having oral problem' if the score was two or three in at least one of the nine ROAG-J items. Poisson regression was used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs).
Results:
The prevalence of having oral problems was 19% higher in participants with NCDs than those with normal cognitive function after adjusting for potential confounders (PR 1.19, 95% CI: 1.09-1.29). Further analysis showed a higher prevalence of having oral problems for home dwellers with NCDs (PR 1.23, 95% CI: 1.13-1.33) and nursing home residents (PR 1.32, 95% CI: 1.20-1.45) compared to home dwellers with normal cognitive function.
Conclusions:
NCDs were associated with an increased prevalence of oral problems in this Norwegian older adult population. The study suggests the need for increasing oral care for home dwellers with NCDs and nursing home residents.

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...

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

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...
