Authors' conclusion
The trends of lacking preventive dental care and suboptimal oral health outcomes were consistently higher in people with DM or PreDM than in those people without diabetes.
Study context
- Population
- Adults from the National Health and Nutrition Examination Survey (1999 to March 2020) with diagnosed diabetes mellitus (DM), undiagnosed DM, prediabetes or normal glucose
- Participants
- 22,082 adults
- Exposure
- DM vs UnDxDM vs prediabetes mellitus (PreDM) vs normal glucose
- Outcome
- Age, sex, and race-adjusted prevalence of preventive dental service (preventive dental service, self-dental cleaning) and oral health outcomes (≥10 missing teeth, self-rated oral health, periodontitis)
Methodological detailsrepeated national survey (NHANES 1999 to March 2020), age, sex, and race-adjusted prevalence, logistic regression
- Repeated national survey (NHANES 1999 to March 2020)
- Age, sex, and race-adjusted prevalence
- Logistic regression
Main finding

Periodontitis
Trends over time · 1999 to March 2020
