Background Silver diamine fluoride (SDF) is a minimally-invasive preventive service used in the U.S. to avert and arrest caries since 2014. No studies document survival outcomes based in real world delivery. We analyzed 12-month survival outcomes of SDF applied independently or concurrently with other restorative procedures among a population receiving community dental care. Methods We analyzed data on SDF applications from de-identified dental claims on Oregon Health Plan patients served by Advantage Dental in 2016, who had been seen in 2015 (patient n = 2269; teeth n = 7787). We compared survival rates of SDF alone, SDF applied with a sedative filling, and SDF with a same-day restoration. Failure was defined as a restoration or extraction of the tooth 7 to 365 days after initial application. Survival was defined as a patient returning 180 or more days after application whose tooth did not have a restoration or extraction. Differences were assessed through Wilcoxon equality of survivor function tests and log-rank equality of survivor tests to compare failure rates, Cox Proportional Hazards models to assess factors associated with survival of SDF, and Kaplan–Meier survival estimate to calculate the probability of survival over time. Results SDF alone had an overall survival rate of 76%. SDF placed with sedative filling and with a same-day restoration had survival rates of 50% and 84% respectively, likely reflecting treatment intent. SDF alone survived exceptionally well on primary cuspids, permanent molars, and permanent bicuspids and among patients aged 10 to 20 years, with modest variation across caries risk assessment categories. A single annual application of SDF was successful in 75% of cases. Among SDF failures on permanent dentition, more than two-thirds of teeth received a minor restoration. Conclusion SDF is a minimally invasive non-aerosolizing option that prevented non-cavitated lesions and arrested early decay among community dentistry patients when applied independently or concurrently with restorative procedures. Professional organizations, policy makers, providers, and payors should broaden optional SDF use by informing clinical guidelines, reimbursement policies, and treatment decisions. Future research should address clinical, social, service delivery, workforce, and economic outcomes using diverse population-based samples, and the mechanisms underlying single application success and caries prevention potential.
To ascertain the financial impact associated with the underutilization of preventive dental care for adults enrolled in Medicaid. Methods: We used adult claims data for patients aged 21-64 in the IBM Watson Marketscan Medicaid database. Enrollees were included if they had at least one dental claim in 2019 and were continuously enrolled between 2014 and 2019. We then evaluated the costs of their dental care in 2019, based on the number of years of preventive dental care they received between 2014 and 2018. We also assessed Emergency Department (ED) utilization for dental conditions, oral surgeries, and dental-related opioid prescriptions. Results: The average Medicaid enrollee with five continuous years of preventive care prior to 2019 experienced 43% lower costs than an individual who received no preventive dental care at all. Most of the savings were a result of fewer oral surgeries. A Medicaid enrollee with no preventive dental visits was eight times more likely to have an ED visit for a nontraumatic dental condition (NTDC), seven times more likely to have oral surgery and six times more likely to receive a dental-related opioid prescription compared to those who had a dental prevention visit every year in the 5-year lookback period. Conclusions: Regular preventive dental care in the lookback period was associated with significant savings in overall dental care costs when compared to dental care costs for those individuals who received no or few preventive visits. Prior preventive dental care was also associated with lower rates of ED-NTDC utilization, oral surgery, and dental-related opioid prescriptions.
Background: The causes of preterm birth are multi-dimensional, including delayed and inadequate prenatal services as well as other medical and socioeconomic factors. This study aimed to examine the different levels of association between preterm birth and major medical co-morbidities among various racial/ethnic women enrolled in Medicaid. Methods: This is a retrospective analysis of 457,200 women aged between 15 and 44 with a single live birth from the IBM® MarketScan® Multi-State Medicaid Database from 2014 to 2015. Preterm birth, defined by delivery before 37 completed weeks of gestation, was the primary dependent variable. All births were dichotomously categorized as either preterm or full-term birth using the International Classification of Diseases, Ninth Revision, Clinical Modification codes. Independent variables included race/ethnicity, categorized as non-Hispanic white, non-Hispanic black, Hispanic, or other. Medical co-morbidities included smoking, drug dependence, alcohol dependence, diabetes, and hypertension. Total healthy prenatal visit count and high-risk prenatal visit encounters identified during 30 weeks prior to the delivery date were included in the analysis. Results: A significantly higher preterm birth rate was found in black women after controlled for medical comorbidities, age, prenatal visit count, and high-risk pregnancy. Different levels of association between preterm birth outcome and major medical co-morbidities were examined among various racial/ethnic women enrolled in Medicaid. Drug dependence was associated with higher odds of preterm birth in black (OR = 2.56, 95% CI [1.92-3.41]) and white women (OR = 2.12, 95% CI [1.91-2.34]), when controlled for other variables. In Hispanic women, diabetes (OR=1.44, 95% CI [1.27, 1.64]) and hypertension (OR=1.98, 95% CI [1.74, 2.26]) were associated with higher odds of preterm birth. White women diagnosed with drug dependence had a 14.0% predicted probability of preterm birth, whereas black women diagnosed with drug dependence had a predicted probability of preterm birth of 21.5%. Conclusions: The associations of medical co-morbidities and preterm births varied across racial and ethnic groups of women enrolled in Medicaid. This report calls for future research on racial/ethnic disparity in preterm birth to apply integrative and qualitative approaches to understand the disparity from a contextual perspective, especially for vulnerable pregnant women like Medicaid enrollees.
Introduction: Early childhood caries (ECC), despite being preventable, remains the most prevalent disease of childhood, particularly in children between the ages of 2 and 5 y. The association between the type of health care provider completing initial oral health examinations and subsequent dental caries in children under 6 y of age is unclear. Objective: The objective of the current study is to longitudinally assess the association between age at first oral health examination and provider type at first oral health examination on dental treatment for children under 6 y of age. Methods: Deidentified administrative claims data were used from the IBM Marketscan Multi-State Medicaid Database (n = 2.41 million Medicaid-enrolled children younger than 6 y in 13 states from 2012 to 2017). A Kaplan–Meier survival analysis was used to examine the association between age at first oral health examination and provider type with first treatment of dental caries at follow-up. Results: The adjusted hazard ratio (HR) of dental caries for children whose first oral health examination at 4 y of age is 5.425 times higher than for children whose first oral health examination was before 1 y of age (95% confidence interval [CI], 5.371–5.479). The adjusted HR of dental caries for children seen by pediatric dentists (HR = 1.215; 95% CI, 1.207–1.223) and physicians (HR = 2.618; 95% CI, 2.601–2.635) was higher than those seen by a general dentist. Conclusions: Findings from this study highlight the importance of children having their first oral health examination no later than 12 mo of age in accordance with existing guidelines and referrals from physicians to prevent the need for invasive treatment. Knowledge of Transfer Statement: Results of this study emphasize the need for a child’s first oral health examination to be completed no later than 12 mo of age to prevent dental caries. Reinforcement and referrals by physicians based on this recommendation facilitate early establishment of a dental home in young children.
