A comparative analysis of public and private dental benefit payer types for the provision and outcomes of root canal therapy on permanent teeth of children and adolescents in Massachusetts

BackgroundDespite substantial increases in dental benefits and improvements in the use of dental services among children and adolescents in the United States, oral health disparities according to dental insurance payer type persist.MethodsThe authors used an all-payer claims (2013-2017) database to perform a comparative analysis of the provision and treatment outcomes of an endodontic procedure (root canal therapy) in the permanent teeth of a pediatric population aged 6 through 18 years, according to dental insurance payer type. Statistical analyses, including logistic regression, Cox proportional hazards regression, and the Kaplan-Meier method, were performed at person and tooth levels.ResultsCompared with privately insured children and adolescents, public-payer children and adolescent beneficiaries were more likely to have had root canal therapy (adjusted odds ratio, 1.91; 95% CI, 1.73 to 2.11) and had poorer treatment outcomes associated with the procedure (adjusted hazard ratio, 2.19; 95% CI, 1.53 to 3.14; P < .0001) during the study period. Those enrolled in private insurance were more likely to receive treatment from an endodontist (specialist in providing root canal therapy) (P < .0001). Amounts allowed and paid by the insurer were significantly higher for private payers (P < .001).ConclusionsThere were significant differences in the provision and outcomes of endodontic treatment between privately and publicly insured children and adolescents.Practical ImplicationsDespite ostensibly equal access to care, differences in the provision of oral health care exist between privately and publicly insured patients. These differences may be contributing to persisting oral health disparities.     

Changes in dental care use patterns due to COVID-19 among insured patients in the United States

BackgroundDemand for dental services has been known to be linked closely to dental insurance and disposable income. Widespread economic uncertainty and health systems changes due to COVID-19 thus may have a significant impact on dental care use.MethodsUsing deidentified dental practice management data from 2019 and 2020, the authors observed variations in dental care use among insured patients since the COVID-19 outbreak (during the period of practice closure and after the reopening) by patient age, procedure type, insurance type, practice size, geographic area, and reopening status. The authors examined whether the rebound in procedure volumes at dental practices can be explained by county-level characteristics using hierarchical regression models.ResultsAlthough dental care use among privately insured patients fully rebounded by August 2020, use still remained lower than the prepandemic level by 7.54% among the publicly insured population. Demand for teledentistry increased 60-fold during practice closure. Geographic characteristics—such as median household income, percentages of rural or Black populations, and dental care professional shortage designations—were associated significantly with the number of procedures performed at dental practices.ConclusionsAs a result of COVID-19, dental practices experienced substantial decreases in procedure volume, particularly among patients covered by public insurance or residing in underserved areas.Practical ImplicationsDuring economic downturns, state health officials should be encouraged to adopt policies to expand access to oral health care for vulnerable populations via oral health promotion strategies and increasing the supply of dentists or midlevel dental care providers in underserved areas.     

Comparative analysis of dental procedure mix in public and private dental benefits programs

BackgroundThere is little published research on whether public and private dental benefits plans affect the types of oral health care procedures patients receive. This study compares the dental procedure mix by age group (children, working-age adults, older adults), dental benefits type (Medicaid and Children’s Health Insurance Program, private), and level of Medicaid dental benefits by state (emergency only, limited, extensive).MethodsThe authors extracted public dental benefits claims data from the 2018 Transformed Medicaid Statistical Information System. To compare procedure mix with beneficiaries who had private dental benefits, the authors used claims data from the 2018 IBM MarketScan dental database. The authors categorized dental procedures into specific service categories and calculated the share of procedures performed within each category. They analyzed procedure mix by age, plan type (fee-for-service, managed care), and adult Medicaid benefit level.ResultsAside from orthodontic services, the dental procedure mix among children with public and private benefits is similar. Among adults with public benefits, surgical interventions make up a higher share of dental procedures than routine preventive services.ConclusionsChildren with public benefits have a procedure mix comparable with those with private benefits. There are substantial differences in procedure mix between publicly and privately insured adults. Even in states that provide extensive dental benefits in Medicaid, those programs primarily finance invasive surgical treatment as opposed to preventive treatment.Practical ImplicationsThere is a need to assess best practices in publicly funded programs for children and translate those attributes to programs for adults for more equitable benefit design and care delivery across public and private insurers.     

Impact of disability diagnosis on dental care use for adults in the United States: Status matters

BackgroundApproximately 25% of adults in the United States have a disability that limits function and independence. Oral health care represents the most unmet health care need. This population has been found to have decreased oral health outcomes compared with the general population.MethodsThe authors used the 2018 adult National Health Interview Survey to assess the association between disability status and dental care use (dental visit within or > 2 years). Disability status was categorized as adults with an intellectual, acquired, or developmental disability (IADD) that limits function, other disability that limits function, or no disability, on the basis of diagnoses of birth defect, developmental diagnosis, intellectual disability, stroke, senility, depression, anxiety, or emotional problem, all causing problems with function.ResultsAdults with an IADD with functional and independence-limiting disabilities experienced higher crude odds of going 2 years or more without a dental visit than adults without disabilities (odds ratio [OR], 2.29; 95% CI, 1.96 to 2.67). This association was part of a significant interaction and was stronger among those with IADDs who could afford oral health care (OR, 1.73; 95% CI, 1.47 to 2.14) than among those who could not afford oral health care (OR, 1.21; 95% CI, 0.88 to 1.67; P value of interaction <.01).ConclusionsAdults with IADDs have decreased access to oral health care compared with adults with other disabilities or without disabilities. The inability to afford oral health care lessens the impact of disability status.Practical ImplicationsDentists can use this study to understand the implications of IADD diagnoses on dental care use and make efforts to facilitate care for these patients.     

Dental health status,use, and insurance coverage among adults with chronic conditions: Implications for medical-dental integration in the United States

BackgroundThe authors examined potential benefits and difficulties in integrating oral health care and medical care for adults with chronic conditions (CCs).MethodsThe authors used National Health and Nutrition Examination Survey 2009-2016 data to estimate crude (age- and sex-standardized) and model-adjusted estimates to examine the association between dental disease (severe tooth loss, untreated caries) and chronic disease (≥ 3 CCs, fair or poor health) and Medical Expenditure Panel Survey 2014-2016 data to estimate crude estimates of past-year medical and dental use and financial access according to CC status. Reported differences are significant at P < .05.ResultsNational prevalences of reporting fair or poor health and 3 or more CCs were both approximately 15%. Standardized prevalence of dental disease was notably higher among adults reporting CCs than those not reporting. After controlling for covariates, the magnitude of the association was substantially lower, although the association remained significant. Adults with CCs were approximately 50% more likely to report having a past-year medical visit and no dental visit than those not reporting CCs. Among adults reporting CCs, prevalence of having no private dental insurance and low income was approximately 20% and 60% higher, respectively, than that among adults not reporting CCs.ConclusionsAdults with CCs had higher prevalence of dental disease, past-year medical visit and no dental visit, and limited financial access.Practical ImplicationsMedical visits may be the only opportunity to provide dental education and referrals to adults with CCs. Improved medical-dental integration could improve oral health care access and oral health among these adults who are at higher risk of dental disease.     

Oral health needs among youth with a history of foster care: A population-based study

BackgroundChildren and youth in foster care are considered to have special health care needs, including oral health care needs. This study compares the self-identified oral health care needs and access to oral health care among youth who have and have not experienced foster care.MethodsData were drawn from the 2019 Minnesota Student Survey, a statewide survey of public school students in the 5th, 8th, 9th, and 11th grades (N = 169,484). Youth with a history of foster care (3%) were compared with youth with no history of foster care for 7 oral health indicators.ResultsYouth with a history of foster care reported more oral health problems and less access to oral health care than their peers with no history of foster care. Using logistic regression to control for key covariates, the odds of an oral health problem for youth with a history of foster care were 1.54 higher (95% confidence interval, 1.44 to 1.65) than for their peers.ConclusionsYouth with a history of foster care report more oral health problems than their peers. Dentists should recognize the oral health concerns of these youth in the context of their special health care needs and be prepared to render appropriate care. Future studies should explore barriers to oral health care among this vulnerable population.Practical ImplicationsYouth in foster care have self-identified oral health care needs that should be assessed by dental professionals.     

Association between first oral examination characteristics and dental treatment needs in privately insured children: A claims data analysis

BackgroundEarly childhood caries (ECC) remains the most common, preventable infectious disease among children in the United States. Screening is recommended after the eruption of the first tooth, but it is unclear how the age at first dental examination is associated with eventual restorative treatment needs. The authors of this study sought to determine how provider type and age at first dental examination are associated longitudinally with caries experience among children in the United States.MethodsDeidentified claims data were included for 706,636 privately insured children aged 0 through 6 years as part of the nationwide IBM Watson Health Market Scan (2012-2017). The authors used Kaplan-Meier survival analysis to describe the association between the age of first visit and restorative treatment needs.ResultsA total of 21% of this population required restorative treatment, and the average age at first dental examination was 3.6 years. A multivariable Cox proportional hazards model showed increased hazard for restorative treatment with age at first dental visit at 3 years (hazard ratio, 2.05; 95% CI, 1.97 to 2.13) and 4 years (hazard ratio, 3.99; 95% CI, 3.84 to 4.16).ConclusionThe high proportion of children requiring restorative treatment and late age at first dental screening show needed investments in educating general dentists, medical students, and pediatricians about oral health guidelines for pediatric patients.Practical ImplicationsCommunicating the importance of children establishing a dental home by age 1 year to parents and health care professionals may help reduce disease burden in children younger than 6 years.     

Oral Health in America: Implications for dental practice

BackgroundImportant, but insufficient, gains have been achieved in access to and delivery of oral health care since the 2000 US surgeon general’s report on oral health in America. Access to care has increased for children and young adults, but considerable work remains to meet the oral health care needs of all people equitably. The National Institutes of Health report, Oral Health in America: Advances and Challenges, reviews the state of the US oral health care system, achievements made since 2000, and remaining challenges. In this article, the authors highlight key advances and continuing challenges regarding oral health status, access to care and the delivery system, integration of oral and systemic health, financing of oral health care, and the oral health workforce.ResultsPublic insurance coverage has increased since 2000 but remains limited for many low-income, minority, and older adult populations. The oral health care workforce has expanded to include new dental specialties and allied professional models, increasing access to health promotion and preventive services. Practice gains made by women and Asian Americans have not extended to other minority demographic groups. Oral health integration models are improving access to and delivery of patient-centered care for some vulnerable populations.Conclusions and Practical ImplicationsCoordinated policies and additional resources are needed to further improve access to care, develop dental insurance programs that reduce out-of-pocket costs to lower-income adults, and improve the integration of oral and medical health care delivery targeting a common set of patient-centered outcomes. Dental care professionals need to fully participate in meaningful and system-wide change to meet the needs of the population equitably.     

Effects of the COVID-19 pandemic on children’s oral health and oral health care use

BackgroundThe COVID-19 pandemic led to early restrictions on access to oral health care and social distancing requirements. The authors examined the early effects of the COVID-19 pandemic on children’s oral health and access to oral health care in the United States.MethodsUsing nationally representative data from the National Survey of Children’s Health, the authors compared several measures of children’s oral health and oral health care use early during the pandemic in 2020 with 1 year earlier. Logistic (multinomial or binary) regression models were estimated, adjusting for several child and household covariates and state fixed effects. Similar comparisons were estimated for 2019 relative to 2018 to evaluate prepandemic trends.ResultsChildren in 2020 were 16% (relative risk ratio, 0.84; 95% CI, 0.75 to 0.93) less likely to have excellent dental health as perceived by parents and 75% (relative risk ratio, 1.75; 95% CI, 1.14 to 2.67) more likely to have poor dental health than in 2019. In addition, children in 2020 had higher risk of bleeding gingivae (odds ratio, 1.46; 95% CI, 1.16 to 1.85). The likelihood of having a dental visit in the past 12 months was 27% (odds ratio, 0.73; 95% CI, 0.65 to 0.82) lower in 2020, including lower likelihood for preventive visits. The differences between 2020 and 2019 were observed across demographic and socioeconomic subgroups. There were no such differences between 2019 and 2018.ConclusionsThere was a widespread decline in children’s oral health status and access to oral health care early during the COVID-19 pandemic.Practical ImplicationsPrompt policies and oral health campaigns are needed to counter the pandemic effects and increase timely access to dental services.     

Dental services use before and after inpatient admission among privately insured adults in the United States

BackgroundOral health has been connected to worse outcomes among hospitalized patients, but access to oral health care services in the hospital setting is limited. It is unknown how a hospital admission affects subsequent dental services use.MethodsThe authors conducted a retrospective analysis of insurance claims data from a national private insurer. Patients were included if they were admitted to the hospital and had visited a dentist at least once in the year before or after admission. Total number of dental visits, as well as Code on Dental Procedures and Nomenclature codes associated with these visits in the year before and after a hospital stay, patient demographic characteristics, hospital admission diagnosis, and length of stay were recorded. Differences in dental services use before and after the hospital stay were calculated.ResultsIn total, 107,116 patients met inclusion criteria. There were fewer dental visits after admission (mean [standard deviation {SD}] 1.6 [1.7] than before admission (mean [SD] 1.9 [1.8]; P < .0001). Fewer procedures were recorded in the year after discharge (mean [SD] 7.0 [11.4] total Code on Dental Procedures and Nomenclature codes versus 8.5 [12.5] in the year before admission; P < .0001). The number of diagnostic and restorative services delivered was higher after admission, and the number of periodontic, endodontic, oral surgery, and prosthodontic services decreased (overall Pearson χ², P < .0001).ConclusionsPatients are less likely to visit a dentist after a hospital stay, although impact on oral health is unknown.Practical ImplicationsHospitalization may contribute to already existing oral health disparities. Hospital teams and dentists should work together to enhance access to oral health care after hospital admission.     

Preventive oral health care use for children with special health care needs aged 6 through 12 years enrolled in Medicaid: A mixed methods study

BackgroundThe authors aimed to assess preventive oral health care (POHC) use for children with special health care needs (CSHCN) aged 6 through 12 years enrolled in Medicaid and identify intervention strategies to improve oral health.MethodsIn this sequential mixed methods study, the authors analyzed 2012 Medicaid data for children aged 6 through 12 years in Washington state. They used eligibility and claims data to identify special health care needs status (independent variable) and POHC use (outcome variable). They ran modified Poisson regression models to generate prevalence rate ratios. They coded data from 21 key informant interviews deductively using content analytic techniques.ResultsOf the 208,648 children in the study, 18% were identified as CSHCN and 140,468 used POHC (67.3%). After adjusting for confounding variables, the authors found no difference in POHC use by special health care need status (prevalence rate ratio, 1.00; 95% CI, 0.99 to 1.01; P = .91). In the qualitative analysis, the authors identified 5 themes: caries risk depends on a child’s specific health condition, caries complicates overall health, having a special need creates a bigger barrier to care, legislation alone is “not going to make much of a dent,” and improvements across all fronts are needed to promote the oral health of CSHCN in Medicaid.ConclusionsCSHCN enrolled in Medicaid are just as likely as children without special health care needs to use POHC, although barriers to oral health care access persist for CSHCN.Practical ImplicationsFuture efforts should focus on comprehensive strategies that address the varying levels of dental disease risk and difficulties accessing oral health care within the diverse group of CSHCN.     

Pediatric dental care use and parent- or caregiver-rated oral health among Alabama children enrolled in Medicaid

BackgroundReducing caries and improving access to dental care is a public health challenge. Understanding low use of dental care is of critical importance. This study estimated parent- or caregiver-reported prevalence and identified factors associated with children’s dental care use, including the association with children’s oral health.MethodsA cross-sectional analysis of children enrolled in Medicaid in Alabama, using data from the 2017 statewide Consumer Assessment of Healthcare Providers and Systems Health Plan Survey, was conducted. Associations were measured using adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) from logit regression and generalized linear model postestimation of least-squares means.ResultsThe 6-month prevalence of children receiving dental care was 70.4%. Children aged 0 through 3 years (aPR, 0.72; 95% CI, 0.53 to 0.91) had lower prevalence of care than other age groups. The prevalence of low-rated oral health was 9.2%. Low-rated oral health was associated with not receiving dental care (aPR, 1.50; 95% CI, 1.12 to 1.87) and parental education of 8th grade or less (aPR, 2.59; 95% CI, 1.20 to 3.98). Falsification tests determined that dental care use was not associated with ratings for overall health (aPR, 1.18; 95% CI, 0.83 to 1.52) or emotional health (aPR, 1.06; 95% CI, 0.79 to 1.33).ConclusionsIt was observed that children not receiving dental care had low-rated oral health; however, as a cross-sectional study, it was not possible to assess the temporality of this relationship.Practical ImplicationsOral health care providers should continue to recognize their role in educating parents and providing anticipatory guidance on children’s oral health.     

Persistent but narrowing oral health care inequalities in Canada from 2001 through 2016

BackgroundSimilar to the United States, inequality in oral health care use is longstanding in Canada. It remains unclear whether this inequality is improving or worsening. In this study, the authors report on income-related inequality in dental visits in Canada and across its provinces over time and interprovincial inequality in dental visits among Canadian provinces.MethodsThe authors used 7 nationally representative health surveys of the Canadian population and collected data from 2001 through 2016. The magnitude of income-related inequality was measured using the slope index of inequality and relative index of inequality. Interprovincial inequality was examined using a number of indexes including the Theil index.ResultsIncome-related inequality in dental visits was present in all survey years, with people in higher income groups reporting higher dental visit prevalence rates. However, results from the slope index of inequality and relative index of inequality showed a steady decline, meaning there was a decrease in the magnitude of inequality over time. Absolute and relative inequality decreased by 7.2% and 22.9% from 2000 through 2016, respectively. A similar decline was observed across most Canadian provinces. Interprovincial differences in dental visits also decreased over time.ConclusionsThere appears to be persistent but narrowing income-related inequality in dental visits in Canada and across its provinces over time. In addition, it appears that Canadian provinces are becoming more equal in terms of dental services use.Practical ImplicationsNarrowing income-related inequality in dental visits in Canada is promising, suggesting a more equal distribution of dental visits. However, unequal use of dental services remains an issue affecting the Canadian population.     

Emergency department visits for infectious oral conditions in Massachusetts, 2014 through 2018

BackgroundThe authors aimed to measure population-based preventable emergency department (ED) visits related to infectious oral conditions (IOCs) in Massachusetts and to examine the associated sociodemographic factors to support prevention efforts.MethodsA statewide retrospective analysis of ED visits related to IOCs in Massachusetts from 2014 through 2018 was conducted using a Center for Health Information and Analysis database. The authors described patients' characteristics, dental diagnoses frequencies, emergency severity, lengths of stay, associated treatment, and costs. Multilevel logistic regression was used to assess factors associated with IOC visits.ResultsIOC visits in 2014 through 2018 were 1.2% (149,777) of the total ED visits, with an estimated cost of $159.7 million. There was an annual decline in the prevalence of IOC visits from 2014 through 2018. After adjusting for sociodemographic factors, odds of IOC were higher among males (adjusted odd ratio [AOR], 1.26; 95% CI, 1.24 to 1.27), non-Hispanic Blacks compared with non-Hispanic Whites (AOR, 1.03; 95% CI, 1.02 to 1.06), people residing in dental health care professional shortage areas (AOR, 1.06; 95% CI, 1.04 to 1.07), public insurance beneficiaries (AOR, 1.90; 95% CI, 1.87 to 1.93), or uninsured (AOR, 2.60; 95% CI, 2.54 to 2.66) compared with privately insured.ConclusionsThere was an annual decline in the prevalence of IOC visits from 2014 through 2018. Higher odds of IOC visits were associated with young adults, Black patients, uninsured people, public insurance beneficiaries, and people who reside in dental health care professional shortage areas.Practical ImplicationsThe authors provided statewide data to support proposed policies to improve oral health care in Massachusetts. IOCs are mostly preventable, but well-coordinated care between medicine and dentistry is integral for prevention.     

Impact of Medicaid dental coverage expansion on self-reported tooth loss in low-income adults

BackgroundLow-income adults delay oral health care due to cost more than any other health care service. These delays lead to caries, periodontal disease, and tooth loss. Expanding Medicaid dental coverage has increased dental visits, but the potential impact on previously unmet oral health needs is not well understood.MethodsIn this analysis, the authors estimated the association between Medicaid dental expansion and tooth loss. Data on self-reported tooth loss among adults below 138% federal poverty guideline were obtained from the Behavioral Risk Factor Surveillance System. A difference-in-differences regression was estimated. Additional analyses stratified according to age and separated extensive and limited dental benefits.ResultsExpanding Medicaid dental coverage is associated with increased probability of total tooth loss of 1 percentage point in the total sample, representing a 20% relative increase from the pre-expansion rate. This increase was concentrated in states offering extensive dental benefits and was largest (2.5-percentage-point greater likelihood) among adults aged 55 through 64 years for whom both extensive and limited dental benefits were associated with total tooth loss.ConclusionsMedicaid expansion with extensive dental benefits was associated with increased total tooth loss among low-income adults. This finding suggests that greater access to oral health care addressed previously unmet oral health needs for this population.Practical ImplicationsAs public dental coverage continues to expand, dental care professionals may find themselves treating a greater number of patients with substantial, previously unmet, oral health needs. Additional research to understand the long-term effects of Medicaid dental insurance for adults on their oral health is needed.     

Oral health and oral health care use among able-bodied adults enrolled in Medicaid in Kentucky after Medicaid expansion: A mixed methods study

BackgroundOral health care use remains low among adult Medicaid recipients, despite the Patient Protection and Affordable Care Act’s expansion increasing access to care in many states. It remains unclear the extent to which low use reflects either low demand for care or barriers to accessing care. The authors aimed to examine factors associated with low oral health care use among adults enrolled in Medicaid.MethodsThe authors conducted a survey from May through September 2018 among able-bodied (n = 9,363) Medicaid recipients who were aged 19 through 65 years and nondisabled childless adults in Kentucky. The survey included questions on perceived oral health care use. Semistructured interviews were also conducted from May through November 2018 among a subset of participants (n = 127).ResultsMore than one-third (37.8%) of respondents reported fair or poor oral health, compared with 26.2% who reported fair or poor physical health. Although 47.6% of respondents indicated needing oral health care in the past 6 months, only one-half of this group reported receiving all of the care they needed. Self-reported barriers included lack of coverage for needed services and lack of access to care (for example, low provider availability and transportation difficulties).ConclusionsLow rates of oral health care use can be attributed to a subset of the study population having low demand and another subset facing barriers to accessing care. Although Medicaid-covered services might be adequate for beneficiaries with good oral health, those with advanced dental diseases and a history of irregular care might benefit from coverage for more extensive restorative services.Practical ImplicationsThese results can inform dentists and policy makers about how to design effective interventions and policies to improve oral health care use and oral health outcomes.
