Self-reported oral health is associated with systemic health outcomes and all-cause mortality
Background:
Self-reported oral health questions (OHQs) are used commonly for epidemiologic surveillance of periodontal disease (PD). The authors' objective was to investigate how OHQs are associated with well-established systemic comorbidities of PD and their impact on all-cause mortality. The authors hypothesized that OHQs exhibit associations with systemic comorbidities similar to PD.
Methods:
Two independent data sets were used to achieve these objectives: the Women's Health Study, a prospective cohort of women 45 years or older with self-reported information on PD, OHQs, cardiovascular disease, diabetes, and osteoporosis in various timeframes (continuous from 1992) and the National Health and Nutrition Examination Survey (NHANES), with data on OHQs and linked mortality (1999-2018). The authors applied multivariate logistic regression models and Cox proportional hazard regression survival analyses to test their hypotheses.
Results:
The Women's Health Study participants who reported having PD until 2006 were more likely to later report deteriorating oral health, bone loss around their teeth, or periodontal treatment in 2018. Self-rated fair or poor oral health was independently associated with increased risk of cardiovascular disease (odds ratio, 1.39; 95% CI, 1.14 to 1.69; P < .001), diabetes (odds ratio, 1.21; 95% CI, 1.02 to 1.43; P = .028), and osteoporosis (odds ratio, 1.60; 95% CI, 1.38 to 1.84; P < .001). National Health and Nutrition Examination Survey participants who self-rated fair or poor oral health had higher risks of all-cause mortality (hazard ratio, 1.18; 95% CI, 1.02 to 1.37; P = .027).
Conclusions:
Self-reported oral health had a similar magnitude of associations with systemic comorbidities as established with PD previously. Moreover, self-rated fair or poor oral health, suboptimal dental visits, or infrequent flossing were associated with increased all-cause mortality.
Practical Implications:
These results support the use of OHQs in assessing systemic connections, especially when clinical dental access is limited. This clinical trial was registered at ClinicalTrials.gov. The registration number is NCT00000479.

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 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...
