Assessing the role of dental insurance in oral health care disparities in Canadian adults.

Background: This study examines the association of dental insurance with oral health care access and utilization in Canada while accounting for income and sociodemographic factors. It contributes to a baseline of oral health care disparities before the implementation of the Canadian Dental Care Plan (CDCP). Data and methods: This retrospective study of Canadians aged 18 to 64 years is based on data from the 2022 Canadian Community Health Survey. Multivariable logistic regression was employed to evaluate the association of dental insurance with the recency and frequency of dental visits, as well as avoidance of dental care because of cost. Results: Overall, 65.7% of Canadians reported visiting a dental professional in the previous year: 74.6% of those with private insurance, 62.8% with public insurance, and 49.8% uninsured. Cost-related avoidance of dental care was 16.0%, 20.9%, and 47.4% for the privately insured, publicly insured, and uninsured, respectively. After adjustment, adults with private (odds ratio [OR]=2.54; 95% confidence interval [CI]: 2.32 to 2.78) and public (OR=2.17; 95% CI: 1.75 to 2.68) insurance were more likely to have visited a dental professional in the last year compared with those without insurance. Similarly, both private (OR=0.22; 95% CI: 0.20 to 0.25) and public (OR=0.22; 95% CI: 0.17 to 0.29) insurance holders showed a significantly lower likelihood of avoiding dental visits because of cost when compared with uninsured individuals. Interpretation: This study showed the significant association of dental insurance with access to oral health care in Canada, contributing to setting a critical benchmark for assessments of the CDCP's effectiveness in addressing oral health disparities.

Access to restorative oral health care for children living in Illinois with Medicaid vs private dental insurance: An audit study.

BACKGROUND: Public dental insurance programs for children aim to provide access to care, but barriers remain that preclude care delivery. Understanding these barriers is an important health policy concern. METHODS: A telephone audit sought to ascertain availability of oral health care for children in dental offices eligible to bill Medicaid. Female callers posing as mothers called eligible offices requesting appointments. In this cross-over design, offices were randomized to public or private insurance for initial calls and then to the other condition after a washout period. RESULTS: Using mixed models, privately insured patients had 5.9 times (95% CI, 4.55 to 7.69) greater odds of obtaining an appointment than Medicaid patients. Compared with patients in Cook County, suburban patients had slightly better odds, whereas nonurban patients in larger and smaller rural counties had lower odds of success. CONCLUSIONS: Medicaid compares poorly with private insurance for providing access to pediatric oral health care. Regardless of insurance conditions, access is poor in less urban environments compared with metropolitan communities. PRACTICAL IMPLICATIONS: Even Medicaid-enrolled dental practices limit the care they extend to insured children. Providing Medicaid by itself cannot overcome large oral health care access disparities, which are greatest in rural communities.

Implication of dental insurance status on patterns of pre-radiation dental extraction and risk of osteoradionecrosis of the jaw in head-and-neck cancer patients.

Oral toxicities such as osteoradionecrosis can be minimized by dental screening and prophylactic dental care prior to head and neck (HN) radiation therapy (RT). However, limited information is available about how dental insurance interacts with prophylactic dental care and osteoradionecrosis. To address this gap in knowledge, we conducted a cohort study of 2743 consecutive adult patients treated with curative radiation for HN malignancy who underwent pre-radiation dental assessment and where required, prophylactic dental treatment. Charts were reviewed to determine patient demographics, dental findings, dental treatment and development of osteoradionecrosis following radiation. Three insurance cohorts were identified: private-insured (50.4 %), public-insured (7.3 %), being patients with coverage through government-funded disability and welfare programs, and self-pay (42.4 %). More than half the public-insured patients underwent prophylactic pre-radiation dental extractions, followed by self-pay patients (44 %) and private-insured patients (26.6 %). After a median follow-up time of 4.23 years, 6.5 % of patients developed osteoradionecrosis. The actuarial rate of osteoradionecrosis in the public-insured patients was 14.7 % at 5-years post-RT, compared to 7.5 % in private-insured patients and 6.7 % in self-pay patients. On multivariable analysis, dental insurance status, DMFS160, age at diagnosis, sex, tumor site, nodal involvement, years smoked and gross income were all significant risk factors for tooth removal prior to HN radiation. However, only public-insured status, tumor site and years smoked were significant risk factors for development of osteoradionecrosis. Our findings demonstrate that lack of comprehensive dental coverage (patients who self-pay or who have limited coverage under public-insured programs) associates strongly with having teeth removed prior to HN RT. Nearly 1 in 6 patients covered under public-insurance developed osteoradionecrosis within 5 years of completing their treatment. Well-funded dental insurance programs for HN cancer patients might reduce the number of pre-RT extractions performed in these patients, improving quality of life post-RT.

Dentist-reported differences in services provided to patients with public vs. private dental insurance.

INTRODUCTION: Variation in dentists' provision of types of dental services based on patients' insurance may impact population access to comprehensive care. The aim of this study was to describe differences in the types of services provided to adult patients with Medicaid versus private insurance among private practice general dentists. METHODS: The data source was a 2019 survey of private practice dentists in Iowa, and the study sample included general dentists with current or recent participation in Iowa's Medicaid program for adults (n = 264). Bivariate analyses were used to compare differences in the types of services provided to privately insured and publicly insured patients. RESULTS: Dentists reported the greatest differences in services provided to patients with public versus private insurance for prosthodontic procedures, including complete dentures, removable partial dentures, and crown and bridge services. Endodontic services were the least frequently provided category of services provided by dentists for both patient groups. Patterns were generally similar among both urban and rural providers. CONCLUSION: Access to dental care for Medicaid members should be evaluated not only on the proportion of dentists who see new Medicaid patients but also on the types of services dentists provide to this population.

Dental health status, dentist visiting, and dental insurance of Asian immigrants in Canada.

OBJECTIVE: This study examined the dental care utilization and self-preserved dental health of Asian immigrants relative to non-immigrants in Canada. Factors associated with oral health-related disparities between Asian immigrants and other Canadians were further examined. METHODS: We analyzed 37,935 Canadian residents aged 12 years and older in the Canadian Community Health Survey 2012-2014 microdata file. Factors (e.g., demographics, socioeconomic status, lifestyles, dental insurance coverage, and year of immigration) associated with disparities in dental health (e.g., self-perceived teeth health, dental symptoms during past one month, and teeth removed due to decay in past one year) and service utilization (e.g., visiting dentist within the last three years, visiting dentist more than once per year) between Asian immigrants and other Canadians were examined using multi-variable logistic regression models. RESULTS: The frequency of dental care utilization was significantly lower in Asian immigrants than their non-immigrant counterparts. Asian immigrants had lower self-perceived dental health, were less likely to be aware of recent dental symptoms, and more likely to report tooth extractions due to tooth decay. Low education (OR = 0.42), male gender(OR = 1.51), low household income(OR = 1.60), non-diabetes(OR = 1.87), no dental insurance(OR = 0.24), short immigration length (OR = 1.75) may discourage Asian immigrants from dental care utilization. Additionally, a perceived lack of necessity to dentist-visiting was a crucial factor accounting for the disparities in dental care uptake between Asian immigrants and non-immigrants. CONCLUSION: Asian immigrants showed lower dental care utilization and oral health than native-born Canadians.

Trends in dental insurance claims in the United States in the context of the COVID-19 pandemic: A 3-year perspective (2019-2022).

OBJECTIVES: We showed in a previous analysis the patterns of disruption for private dental insurance claims in the United States caused by the SARS-CoV-2 pandemic in 2020. The present report examines trends during 2020 and 2021, that is, contrasting perspectives during 2019 with the acute phase of the pandemic in 2020, and 2021. METHODS: Private dental insurance paid claims from a data warehouse were obtained, encompassing a 5% random sample of records between January 2019 and December 2021 for child and adult insureds who filed a claim in 2019, 2020, and 2021. We classified claims into one of four categories based on the likelihood of being associated with urgent/emergency care. RESULTS: The precipitous reduction in dental care claims in March-June 2020 recovered to almost pre-pandemic levels by the fall of 2020. However, a downward decline in private dental insurance claims started in the late fall of 2020 and continued through 2021. Differential impacts in dental care categories-in terms of urgency of care-were evident 2021, closely resembling previous trends in 2020. CONCLUSIONS: Dental care claims from the first year of the 2020 SARS-CoV-2 pandemic were contrasted with perspectives in 2021. A downward trend in demand/availability changes in dental care insurance claims set in for 2021, perhaps linked to perceptions of the overall economic situation. Such downward trend has continued overall, even after considering seasonal changes and the acceleration of the pandemic during the Delta, Omicron, and other variants.

[Proposal and thoughts on establishing and improving multi-level dental insurance in China].

Oral diseases are highly prevalent in China, while oral health services are generally underutilized and public health resources are wasted. Lacking oral insurance may be one of the leading causes. The basic medical insurance of China does not cover dental care in most cities, which is worthy to further discuss. To better understand the experience of dental insurance from international dental care practice, the dental coverage scope, content, co-pay ratio, and effects of oral insurance on oral health improvement from the abroad countries with typical health insurance systems were summarized by using scoping review. Then, we discussed the coverage scope for dental health of basic medical insurance and private insurance in China. We also analyzed the current issues of dental care coverage and cost-share. At last, we proposed thoughts and suggestions to establish and improve a multi-level oral health insurance system with Chinese characteristics under the basic medical insurance frame. In particular, we gave suggestions on increasing the coverage for high dental care xpenditure by ebasic medical insurance, supplying children and teenagers with preventive dental care, and encouraging private insurance companies to cover dental care expenditure.

Access to dental insurance and oral health inequities in the United States.

While the oral health status of the United States (U.S.) population has improved over the years, racial/ethnic inequities are pervasive with Black Americans carrying a greater burden of oral diseases in most measured outcomes. Access to dental care is a major structural and societal determinant of oral health inequities rooted in structural racism. From post-Civil War-era to present day, this essay presents a series of examples of racist policies that have shaped access to dental insurance for Black Americans both directly and indirectly. Additionally, this essay explains the unique challenges of Medicare and Medicaid highlighting the specific disparities that these public insurance programs face, and proposes policy recommendations aimed to reduce racial/ethnic inequities in dental coverage and access to advance the nation's oral health with comprehensive dental benefits in public insurance programs.

Did Dental Insurance Expansion Improve Dental Care Needs Among Korean Adults? Difference in Difference Analysis.

BACKGROUND: In 2012, the Korean government expanded dental insurance for the elderly to promote improved access to dental care. We examined the causal effect of this policy on dental care needs, focusing on low-income older adults. METHODS: We compared data before and after policy implementation using double difference (DD) and triple difference (DDD) analyses. We used the nationally representative data from the Korea National Health and Nutrition Examination Survey from 2010 and 2016-2018. Individuals aged ≥65 years were included in the treatment group, and individuals aged <65 years were included in the control group. RESULTS: Dental insurance expansion was associated with a paradoxical increase in perceived unmet dental needs among elderly individuals (8.8 percentage points increase, 95% CI: 4.7 to 13.0). However, there were improvements in dental prosthetics outcomes (denture wearing [4.0 percentage points, 95% CI: 0.2 to 7.9] and dental implants [5.0 percentage points, 95% CI: 2.1 to 7.9]; P < 0.01). Upon analyzing low-income elderly individuals using DDD analysis, we found that the insurance expansion led to a 21.6% smaller increase in unmet dental needs among low-income adults, compared to high-income adults (95% CI, -35.0 to -8.5; P < 0.01). CONCLUSION: Dental insurance expansion in South Korea resulted in improvements in access to dental prosthetic services overall. It also led to a smaller increase in unmet dental needs among low-income older adults, compared to high-income adults.

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.

BACKGROUND: Despite 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. METHODS: The 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. RESULTS: Compared 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). CONCLUSIONS: There were significant differences in the provision and outcomes of endodontic treatment between privately and publicly insured children and adolescents. PRACTICAL IMPLICATIONS: Despite 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.

"To enroll or not to enroll": a qualitative study on preferences for dental insurance in Iran.

BACKGROUND: Oral public health services are included in primary healthcare. Although oral diseases are preventable, improving oral health has become a concern in many countries. Evidence shows that functioning insurance coverage can significantly increase the use of dental health services, improve quality of services, and reduce financial barriers to utilization. Little evidence exists on households' preferences for dental insurance in Iran. This study seeks to identify the households' preferences for dental insurance in Tehran-Iran. METHOD: This is a qualitative study. We interviewed 84 participants who visited selected public and private dental clinics in Tehran-Iran, from October 2018 until January 2019. All interviews were recorded and transcribed verbatim. We used a mixed inductive/deductive approach for thematic analysis of the interviews. RESULTS: We identified two main themes and 12 sub-themes: pecuniary attributes (insurance premium, coinsurance, insurance coverage granted, discounting option, reimbursement of expenses), and non-pecuniary attributes (notification status, ethical issues, benefits package, contract providers with health insurance, quality of service centers, administrative process, and dental insurance scheme). CONCLUSION: Our participants considered both pecuniary and non-pecuniary attributes for choosing a dental insurance package. Our findings could help, we envisage, policymakers understand Iranian households' preferences for a dental insurance scheme that they afford to buy.

La seguridad social: Un derecho y una obligación para el odontólogo y sus trabajadores / Social security: A right and obligation for the dentist and his workers

La seguridad social es un derecho encaminado a asegurar el bienestar de los ciudadanos que forman parte de una comunidad, y su objetivo principal es brindar a las personas aseguradas un conjunto de medidas públicas que ayuden a la protección de su salud por accidentes de trabajo o enfermedad laboral, desempleo, invalidez, vejez o muerte. De acuerdo con nuestra legislación, toda persona que preste servicios laborales a otro, tiene derecho a ser registrado ante el seguro social para que, en caso de accidente o enfermedad laboral, exista una ins- tancia que asista al trabajador afectado a recuperar su salud sin afectar su economía familiar. Es bastante frecuente que el odontólogo tenga trabajadores a su cargo, quien al fungir como patrón tiene obligaciones específicas ante el Instituto de Seguridad Social que de no cumplir, puede traer consigo sanciones y amonestaciones al profesional. El objetivo del presente artículo es informar al odontólogo sus derechos y obligaciones ante el seguro social mediante una revisión de las normas y leyes que lo imponen (AU)

Social security is a right aimed at ensuring the well-being of citizens who are part of community, and its main objective is to provide insured persons with a set of public measures that help protect their health, due to accidents at work and occupational disease, unemployment, disability, old age or death. In accordance with our legislation, any person who provides labor services to another has the right to registered with the social security so that, in the event of an accident or occupational disease, there is an instance that assists the affecter worker to recover his health without affecting his familiar economy. It is quite common for the dentist to have workers under his charge, who, acting as an employer, have specific obligations with the Social Security Institute, which, if not fulfilled, can bring sanctions and reprimands to the professional. The aim of this article is to inform dentists about their rights and obligations with the Social Security Institute through a review of the laws that impose it (AU)

Trends in dental insurance claims in the United States before and during the SARS-CoV-2 pandemic in 2020.

OBJECTIVES: The SARS-CoV-2 pandemic disrupted health care services. Previous reports estimated reductions in demand and supply of dental care services, but actual changes have not been reported. The present report depicts a perspective of trends in claims from private dental practice in the United States during 2019 and 2020. METHODS: Private dental insurance paid claims data from a data warehouse (encompassing 66+ carriers in the United States) were obtained for children and adults (treatments identified by their American Dental Association Code of Dental Procedures and Nomenclature [CDT]), encompassing a 5% random sample of all records between January 2019 and December 2020. A market-based treatment classification placed CDT codes into one of four categories based on the likelihood of being associated with urgent/emergency care. RESULTS: Claims for 3.8 million patients constituted the 5% random sample for analyses. Substantial drops in the provision of treatment items were quantified for a large segment of private dental insurance plans at a national level, showing differential impacts in dental care categories. CONCLUSIONS: Week-by-week, detailed descriptions of demand/availability changes in dental care throughout the first year of the 2020 SARS-CoV-2 pandemic were obtained through contrasting perspectives in 2019. Provision of dental care and associated impacts fluctuated over time subject to treatment urgency, but also modified as the weeks/months of dental office lockdowns ebbed in and out of the dental market.

Did Expanded Dental Insurance Improve Chewing Ability in the Older Korean Population? Results of an Interrupted Time-series Analysis.

BACKGROUND: In 2012, the Korean National Health Insurance extended its coverage to include denture services for older adults. We examined whether the new policy resulted in improved chewing ability in the eligible population. METHODS: We used interrupted time-series (ITS) analysis, a quasi-experimental design, to analyze the effect of the policy. We used data from the Korea National Health and Nutrition Examination Survey conducted from 2007 to 2016-2018. The study population consisted of two groups: the treatment group, aged 65 years or older and eligible for the dental insurance benefit; and the control group, those younger than 65 years and ineligible. The main evaluated outcome was self-reported chewing difficulty. RESULTS: The ITS analysis showed that chewing difficulty decreased annually by 0.93% (95% CI, -1.30 to -0.55%) and 0.38% (95% CI, -0.59 to -0.16%) after the policy extension in the older than 65 and younger than 65 groups, respectively. However, we could not conclude that the insurance extension affected chewing difficulty because there was a decrease in the control group as well. CONCLUSION: Chewing ability improved in both older and younger adults regardless of dental insurance coverage for older adults. Other exogenous factors probably led to the improvements in chewing ability as well as dental insurance benefits.

Measuring the quality of dental care among privately insured children in the United States.

OBJECTIVE: To examine whether quality of dental care varies by age and over time and whether community-level characteristics explain these patterns. DATA SOURCE: Deidentified medical and dental claims from a commercial insurer from January 2015 to December 2019. STUDY DESIGN: A retrospective cohort study. The primary outcome was a composite quality score, derived from seven dental quality measures (DQMs), with higher values corresponding to better quality. Hierarchical regression models identified person- and zip code-level factors associated with the quality. DATA COLLECTION/EXTRACTION METHODS: Continuously enrolled US dental insurance beneficiaries younger than 21 years of age. PRINCIPAL FINDINGS: Quality was assessed for 4.88 million person-years covering 1.31 million persons. Overall quality slightly improved over time, mostly driven by substantial improvements among children aged 0-5 years by 0.153 points/year (95% confidence interval [CI]:0.151, 0.156). Quality was poorest and declined over time among adolescents with only 20.5% of DQMs met as compared to 42.6% among aged 0-5 years in 2019. Dental professional shortage, median household income, percentages of African Americans, unemployed, and less-educated populations at the zip code level were associated with the composite score. CONCLUSION: Quality of dental care among adolescents remains low, and place of residence influenced the quality. Increasing the supply of dentists and oral health promotion strategies targeting adolescents and low-performing localities should be explored.

Race and payor type for child visits with public health dental hygienist practitioners.

PURPOSE: To examine whether growth in visits to public health dental hygiene practitioners (PHDHPs) providing preventative dental services at a pediatric hospital clinic was predominantly among children receiving public insurance and children of minority background from 2013 to 2017. METHODS: Longitudinal descriptive data analysis from electronic health records for 6856 children under age 18 years who visited PHDHPs co-located at a hospital clinic in Pittsburgh, PA, from 2013 to 2017. We compared visits between white versus non-white children and between children with public, private, and no or missing insurance by year. RESULTS: Visit volume doubled from 2013 (n = 811) to 2017 (n = 1868). The proportion of PHDHP visits with non-white children increased from 77% (n = 625) in 2013 to 87% (n = 1472) in 2017 (p < 0.001). The proportion of PHDHP visits with children with public insurance increased from 72% (n = 585) in 2013 to 82% (n = 1377) in 2017 (p < 0.001). CONCLUSIONS: PHDHPs co-located at a pediatric hospital clinic saw a high proportion of visits from children of non-white race and with public insurance. Visits from children of minority race and with public insurance increased disproportionately as visit volume grew from 2013 to 2017, depicting a vehicle through which historically underserved children increasingly accessed preventive dental services.
