The Impact of Dental Insurance and Medical Insurance on Dental Care Utilization During Pregnancy.

OBJECTIVE: To measure the association between dental and medical insurance with the receipt of dental cleaning during pregnancy. METHODS: We analyzed Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2012 to 2015 on 145,051 women with a recent live birth from 36 states. We used adjusted prevalence ratios [aPR] from multivariable regression to examine the association of dental and medical insurance with receipt of dental cleaning during pregnancy, controlling for selected covariates that influence dental care utilization. RESULTS: Seventy-seven percent (77%) of all women reported having dental insurance during pregnancy. Receipt of dental cleaning before pregnancy was strongly associated with dental cleaning during pregnancy. Among women without pre-pregnancy dental cleaning who had dental insurance, those with Medicaid medical insurance had a significantly higher prevalence of dental cleaning during pregnancy [aPR = 1.42, 95% CI (1.32 - 1.52)], compared to those private medical insurance. Among women without pre-pregnancy dental cleaning, those without dental insurance but with Medicaid medical insurance were about 70% less likely to have dental cleaning during pregnancy compared to those with dental and private medical insurance. CONCLUSIONS FOR PRACTICE: With or without dental insurance, pre-pregnancy dental cleaning was strongly associated with dental cleaning during pregnancy. Dental insurance was an important determinant of dental utilization. Medical insurance had an independent and positive effect. This effect varied by private versus Medicaid medical insurance. Programs which provide women with dental insurance both before and during pregnancy could improve the oral health of maternal and infant populations.

Filled dietary fluoride supplement prescriptions for Medicaid-enrolled children living in states with high and low water fluoridation coverage.

BACKGROUND: Although dietary fluoride (F) supplements (DFS) are recommended for children who use F-deficient drinking water, no studies have examined filled DFS prescriptions across multiple states to examine the dosage consistency with current recommendations or prescription length. METHODS: This sequential cross-sectional analysis used Medicaid claims data for children aged 0.5 through 16 years who in 2011 lived in the 6 states with the lowest and the highest fluoridation coverage (≤ 34% and ≥ 95% of the public water system population fluoridated, respectively). For 2011, the authors calculated the mean percentage of children with filled DFS prescriptions and the change since 2000 across states with high and low fluoridation coverage, the percentage of children with filled DFS prescriptions containing F dosage consistent with current recommendations, and filled DFS prescription length and cost across states. RESULTS: In states with high fluoridation coverage, the mean percentage of children with a filled prescription was < 1% in both years; in states with low fluoridation coverage, this value increased from 0.9% to 10.3%, the highest increase (16.4 percentage points) since 2000 among children aged 0.5 through 2 years. The average prescription length was 72 days. Across states, the mean costs per child prescribed supplements and per enrollee were $17.60 and $1.05, respectively. CONCLUSIONS AND PRACTICAL IMPLICATIONS: Filled prescriptions largely followed current recommendations but reached only a small percentage of children in low-coverage states. The short prescription length indicated limited exposure for caries prevention. Results from these states suggest more children could have longer exposure to the caries-preventive benefits of F at a similar cost with water fluoridation as with DFS.

Awareness Among US Adults of Dental Sealants for Caries Prevention.

INTRODUCTION: Dental sealants applied in childhood can help prevent caries, but knowledge of the availability of sealants and their function is not widespread. We assessed knowledge of dental sealants among US adults and adult parents of children younger than 18 and the differences in knowledge among demographic and socioeconomic groups. METHODS: We used data on 3,550 respondents to the 2015 FallStyles B survey of noninstitutionalized US adults aged 18 or older. Authors constructed estimates by using weights provided to reflect the distribution of the US population. Knowledge of dental sealants was assessed by sex, age, race/ethnicity, education, household income, and parental status. Multivariate analysis was conducted by using a main effects logistic regression model. RESULTS: Overall, 46.3% of adults and 55.1% of parents of children younger than 18 had knowledge of dental sealants. Sealant knowledge was highest among parents, women, respondents aged 45 to 59, and respondents with incomes greater than 200% of the federal poverty level and more than a high school education. Non-Hispanic blacks had less than half the odds of non-Hispanic whites of having knowledge of sealants (adjusted odds ratio [OR] = 0.4), and nonparents had half the odds as parents (OR = 0.5) of knowing. The strongest predictors of parental sealant knowledge were race/ethnicity, sex, and income. CONCLUSION: Disparities in sealant knowledge correspond to disparities in sealant prevalence. Increasing knowledge among low-income and racial/ethnic minority parents could reduce disparities in sealant prevalence and untreated caries.

Vital Signs: Dental Sealant Use and Untreated Tooth Decay Among U.S. School-Aged Children.

BACKGROUND: Tooth decay is one of the greatest unmet treatment needs among children. Pain and suffering associated with untreated dental disease can lead to problems with eating, speaking, and learning. School-based dental sealant programs (SBSP) deliver a highly effective intervention to prevent tooth decay in children who might not receive regular dental care. SBSPs benefits exceed their costs when they target children at high risk for tooth decay. METHODS: CDC used data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 to estimate current prevalences of sealant use and untreated tooth decay among low-income (≤185% of federal poverty level) and higher-income children aged 6-11 years and compared these estimates with 1999-2004 NHANES data. The mean number of decayed and filled first molars (DFFM) was estimated for children with and without sealants. Averted tooth decay resulting from increasing sealant use prevalence was also estimated. All reported differences are significant at p<0.05. RESULTS: From 1999-2004 to 2011-2014, among low- and higher-income children, sealant use prevalence increased by 16.2 and 8.8 percentage points to 38.7% and 47.8%, respectively. Among low-income children aged 7-11 years, the mean DFFM was almost three times higher among children without sealants (0.82) than among children with sealants. Approximately 6.5 million low-income children could potentially benefit from the delivery of sealants through SBSP. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: The prevalence of dental sealant use has increased; however, most children have not received sealants. Increasing sealant use prevalence could substantially reduce untreated decay, associated problems, and dental treatment costs.
