Utilization of dental care and dentate status in diabetic and nondiabetic patients across US states: An analysis using the 2020 Behavioral Risk Factor Surveillance System

Objective

This study examines the differences, by state, in dental care utilization and tooth retention between adults with and without diabetes mellitus (DM).

Methods

We conducted a secondary analysis of data from the 2020 Behavioral Risk Factor Surveillance System, an annual, state-based, random telephone survey of noninstitutionalized US civilian adults. The predictor variable was DM status. The outcome variables were time since the last dental appointment and tooth loss. We utilized multiple multinomial logistic regression models followed by postestimation procedures to determine state-level adjusted proportions for dental visits within the last year and complete teeth retention among DM and non-DM adults.

Results

Among adults with DM, 60.0% reported dentist visits within a year of survey participation, while 53.6% had complete tooth retention. As education and income levels increased, dental attendance and tooth retention increased among adults with DM. Most Southern states had a higher prevalence of DM, a lower proportion of dentist visits, and worse tooth retention among DM adults. Nationally, DM individuals were 4.3 percentage points less likely to visit a dentist and were 7 percent less likely to have complete teeth retention than non-DM adults. Compared with the national average, 25/50 states had greater disparities in dental visits between DM and non-DM adults, and 27/50 states had greater disparities in tooth loss between DM and non-DM adults.

Conclusion

State-level variations indicate geographical and dental coverage influences on DM and dental outcomes. There is a need for state-specific interventions to improve dental access and outcomes for adults with DM.
