Provision of Preventive Dental Services in Children Enrolled in Medicaid by Nondental Providers

Factors perceived by health professionals to be barriers or facilitators to caries prevention in children: a systematic review

BACKGROUND

Considered the most prevalent noncommunicable disease in childhood, dental caries is both an individual and a collective burden. While international guidelines highlight prevention as a major strategy for caries management in children, health professionals still struggle to implement prevention into their clinical practice. Further research is needed to understand the gap between the theoretical significance of dental prevention and its lack of implementation in the clinical setting. This systematic review aims to identify and classify factors perceived by health professionals to be barriers or facilitators to caries prevention in children.

METHOD

A systematic literature search was conducted in three electronic databases (Medline, Web of Science and Cairn). Two researchers independently screened titles, abstracts and texts. To be selected, studies had to focus on barriers or facilitators to caries prevention in children and include health professionals as study participants. Qualitative and quantitative studies were selected. The factors influencing caries prevention in children were sorted into 3 main categories (clinician-related factors, patient-related factors, and organizational-related factors) and then classified according to the 14 domains of the theoretical domains framework (TDF).

RESULTS

A total of 1771 references were found by combining manual and database searches. Among them, 26 studies met the inclusion criteria, of which half were qualitative and half were quantitative studies. Dentists (n = 12), pediatricians (n = 11), nurses (n = 9), and physicians (n = 5) were the most frequently interviewed health professionals in our analysis. Barriers and facilitators to caries prevention in children were categorized into 12 TDF domains. The most frequently reported domains were Environmental Context and Resources, Knowledge and Professional Role and Identity.

CONCLUSION

This systematic review found that a wide range of factors influence caries prevention in children. Our analysis showed that barriers to pediatric oral health promotion affect all stages of the health care system. By highlighting the incompatibility between the health care system's organization and the implementation of caries prevention, this study aims to help researchers and policy-makers design new interventions to improve children's access to caries prevention.

Impact of oral health integration training on children's receipt of oral assessment, fluoride varnish and dental services

OBJECTIVES

To evaluate the impact of an oral health integration training program on children's receipt of oral health and dental services in Southern Oregon.

METHODS

Children under 19 years with at least 6 months of Medicaid enrolment and at least one healthcare visit from 2014 to 2018 were included. The treatment group included children with at least one visit with a trained provider (n = 5541); children with no visits with trained providers (n = 8273) were the control group. The percentage of the treatment group who received oral health assessments was calculated, and regression models were developed to estimate the difference in likelihood of receiving fluoride varnish and dental services between treatment and control groups.

RESULTS

The percentage of children receiving oral health assessments increased over time. Visiting a trained provider was consistently associated, each year, with a greater likelihood of receipt of fluoride varnish and preventive and diagnostic dental services but was not associated with treatment dental services or dental sealants.

CONCLUSIONS

This study reports evidence for the overall impact of an oral health integration training on children's receipt of oral and dental services. Health systems implementing these types of training strategies should consider how to reach specific underserved subgroups, increase paediatric dentists, and expand efforts to include older children.

Association Between Insurance Type and Fluoride Varnish Application During Well-Child Visits in Massachusetts

OBJECTIVE

To compare rates of fluoride varnish (FV) applications during well-child visits for children covered by Medicaid and private medical insurance in Massachusetts.

METHODS

This cross-sectional study analyzed well-child visits for children aged 1 to 5 years paid by Medicaid and private insurance during 2016.Çô18 in Massachusetts. Multivariate regression models, with all covariates interacting with insurance type, were used to calculate odds ratios and adjusted predicted probabilities of fluoride varnish during well-child visits by calendar year and age.

RESULTS

Across 957,551 well-child visits, 40.0% were paid by private insurers. Unadjusted rates of fluoride varnish were significantly lower among well-child visits paid by private insurers (6.6%) than visits paid by Medicaid (14.2%). In the fully interacted regression model, the odds of a visit including fluoride varnish were significantly lower for older children than for children aged 1 for visits paid by both insurance types. Adjusted rates of fluoride varnish increased significantly from 2016 to 2018 for both insurance types. Moreover, rates were higher among visits for children covered under Medicaid than privately insured children in all years, and the differences by insurance type declined over time (2016: 8.0% points, 95% confidence interval.á=.á.êÆ8.7 to .êÆ7.3, 2018: 5.3% points, 95% confidence interval.á=.á.êÆ6.6 to .êÆ3.9).

CONCLUSIONS

Rates of fluoride varnish applications during well-child visits were low for both Medicaid and private insurance despite growth from 2016 to 2018 in Massachusetts. Low rates are concerning because this is a recommended service with the potential to help address racial, geographic, and income-based disparities in access and oral health outcomes.

Medicaid Payment and Fluoride Varnish Application During Pediatric Medical Visits

All Medicaid programs pay for fluoride varnish applications during medical visits for infants and toddlers, but receipt of care varies considerably across states. Using 2006-2014 Medicaid data from 22 states, this study examined the association between Medicaid payment and receipt of fluoride varnish during pediatric medical visits. Among 3,393,638 medical visits, fewer than one in 10 visits included fluoride varnish. Higher Medicaid payment was positively associated with receipt of fluoride varnish during pediatric medical visits. As policymakers consider strategies for increasing young children's access to preventive oral health services, as well as consider strategies for balancing budgets, attention should be paid to the effects of provider payment on access to pediatric oral health services.

Impact of state-level training requirements for medical providers on receipt of preventive oral health services for young children enrolled in Medicaid

OBJECTIVES

Young children enrolled in Medicaid make few dental visits and have high rates of tooth decay. To improve access to care, state Medicaid programs have enacted policies encouraging nondental providers to deliver preventive oral health services (POHS) in medical offices. Policies vary by state, with some states requiring medical providers to obtain training prior to delivering POHS. Our objective was to test whether these training requirements were associated with higher rates of POHS for Medicaid-enrolled children <6 years.

METHODS

This study took advantage of a natural experiment in which policy enactment occurred across states at different times. We used Medicaid Analytic eXtract enrollment and claims data, public policy data, and Area Health Resource Files data. We examined an unweighted sample of 8,711,192 (45,107,240 weighted) Medicaid-enrolled children <6 years in 38 states from 2006 to 2014. Multivariable logistic regression models estimated the odds a child received POHS in a calendar year. Results are presented as adjusted probabilities.

RESULTS

Five or more years after policy enactment, the probability of a child receiving POHS in medical offices was 10.7 percent in states with training requirements compared to 5.0 percent in states without training requirements (P = 0.01). Findings were similar when receipt of any POHS in medical or dental offices was examined 5 or more years post-policy-enactment (requirement = 42.5 percent, no requirement = 33.6 percent, P < 0.001).

CONCLUSIONS

Medicaid policies increased young children's receipt of POHS and at higher rates in states that required POHS training. These results suggest that oral health training for nondental practitioners is a key component of policy success.

Impact of the Affordable Care Act Medicaid expansion on oral surgery delivery at community health centers: an observational study

BACKGROUND

Unmet oral health needs routinely affect low-income communities. Lower-income adults suffer a disproportionate share of dental disease and often cannot access necessary oral surgery services. The Affordable Care Act (ACA) Medicaid expansion created new financial opportunities for community health centers (CHCs) to provide mission-relevant services in low-income areas. However, little is understood in the literature about how the ACA Medicaid expansion impacted oral surgery delivery at CHCs. Using a large sample of CHCs, we examined whether the ACA Medicaid expansion increased the likelihood of oral surgery delivery at expansion-state CHCs compared to non-expansion-state CHCs.

METHODS

Exploiting a natural experiment, we estimated Poisson regression models examining the effects of the Medicaid expansion on the likelihood of oral surgery delivery at expansion-state CHCs relative to non-expansion-state CHCs. We merged data from multiple sources spanning 2012-2017. The analytic sample included 2054 CHC-year observations.

RESULTS

Compared to the year prior to expansion, expansion-state CHCs were 13.5% less likely than non-expansion-state CHCs to provide additional oral surgery services in 2016 (IRR = 0.865; P = 0.06) and 14.7% less likely in 2017 (IRR = 0.853; P = 0.02). All else equal, and relative to non-expansion-state CHCs, expansion-state CHCs included in the analytic sample were 8.7% less likely to provide oral surgery services in all post-expansion years pooled together (IRR = 0.913; P = 0.01).

CONCLUSIONS

Medicaid expansions can provide CHCs with opportunities to expand their patient revenue and services. However, whether because of known dental treatment capacity limitations, new competition, or coordination with other providers, expansion-state CHCs in our study sample were less likely to provide oral surgery services on the margin relative to non-expansion-state CHCs following Medicaid expansion.

Oral Health Among Children and Youth With Special Health Care Needs

OBJECTIVES

We sought to estimate the prevalence of oral health problems and receipt of preventive oral health (POH) services among children and youth with special health care needs (CYSHCN) and investigate associations with child- and family-level characteristics.

METHODS

We used pooled data from the 2016-2018 National Survey of Children's Health. The analytic sample was limited to children 1 to 17 years old, including 23 099 CYSHCN and 75 612 children without special health care needs (non-CYSHCN). Parent- and caregiver-reported measures of oral health problems were fair or poor teeth condition, decayed teeth and cavities, toothaches, and bleeding gums. POH services were preventive dental visits, cleanings, tooth brushing and oral health care instructions, fluoride, and sealants. Bivariate and multivariable logistic regression analyses were conducted.

RESULTS

A higher proportion of CYSHCN than non-CYSHCN received a preventive dental visit in the past year (84% vs 78%, P < .0001). Similar patterns were found for the specific preventive services examined. However, CYSHCN had higher rates of oral health problems compared with non-CYSHCN. For example, decayed teeth and cavities were reported in 16% of CYSHCN versus 11% in non-CYSHCN (P < .0001). In adjusted analyses, several factors were significantly associated with decreased prevalence of receipt of POH services among CYSHCN, including younger or older age, lower household education, non-English language, lack of health insurance, lack of a medical home, and worse condition of teeth.

CONCLUSIONS

CYSHCN have higher rates of POH service use yet worse oral health status than non-CYSHCN. Ensuring appropriate use of POH services among CYSHCN is critical to the reduction of oral health problems.

Outcomes Associated With State Policies Enabling Provision of Oral Health Services in Medical Offices Among Medicaid-enrolled Children

BACKGROUND

To increase receipt of preventive oral health services (POHS), all state Medicaid programs have enacted policies to encourage nondental providers to deliver POHS in medical offices. This study examined if these Medicaid policies improved oral health, as measured by reductions in dental visits with treatment and preventable emergency department (ED) visits for nontraumatic dental conditions (NTDC).

METHODS

Using data on children aged 6 months to up to 6 years from 38 state Medicaid programs during 2006-2014, we used a generalized difference-in-differences estimation approach to examine the probability of a child having, in a year, any dental visits with caries-related treatment and any ED visits for NTDC, conditional on length of policy enactment. Models included additional child-level and county-level characteristics, state and year fixed effects, probability weights, and clustered standard errors.

RESULTS

Among a weighted sample of 45,107,240 child/year observations, 11.7% had any dental visits with treatment and 0.2% had any ED visits for NTDC annually. Children in states with and without medical POHS policies had similar odds of having any dental visits with treatment, regardless of length of policy enactment. Children in states with medical POHS policies enacted for one or more years had significantly greater odds of having any ED visits for NTDC (P<0.05).

CONCLUSIONS

State policies making POHS available in medical offices did not affect rates of dental visits with caries-related treatment, but were associated with increased rates of potentially avoidable ED visits for NTDC. Findings suggest that many young Medicaid-enrollees lack access to dentists.

Recruitment strategies for a pragmatic cluster randomized oral health trial in pediatric primary care settings

Objectives

To describe multilevel recruitment strategies for an ongoing clinical trial in pediatric primary care settings, and assess adoption and reach of these strategies via the RE-AIM framework.

Methods

This study is part of a larger pragmatic cluster randomized clinical trial focused on the effectiveness of interventions on the practice, provider, and caregiver levels on dental utilization for Medicaid-enrolled 3-6 year old children. Pediatric practices were recruited according to the proportion of Medicaid-eligible children, geographic region, and County. In accordance with the RE-AIM framework, providers reached were those approached directly and consented, and those who participated in the intervention training adopted to deliver the intervention. Caregivers reached were those approached and consented at their child's well-child visit to participate in the trial.

Results

Recruitment goals were met over a 21 month period, with an overall enrollment of 18 practices, 62 providers, and 1024 caregivers-child dyads. The majority of practices enrolled were small, suburban, and located in an urban county. The participation rates among approached providers and caregivers was 93% and 84% respectively. Enablers for recruitment was the one-on-one interaction with the provider and caregivers. Barriers to recruitment for caregivers included no-shows and cancellations at well-child visits. Adoption of intervention among providers was high, and caregiver reached were representative of the eligible target population.

Conclusions

Active approaches to recruitment, such as utilizing opinion leaders, in-person recruitment, and building relationships with practice staff, can result in successful enrollment and imp lementation of a multi-level intervention in pediatric primary care settings.

Community Health Centers Maintained Initial Increases in Medicaid Covered Adult Patients at 5-Years Post-Medicaid-Expansion

The Affordable Care Act (ACA) Medicaid expansion created new financial opportunities for community health centers (CHCs) providing primary care in medically-underserved communities. However, beyond evidence of initial policy effects, little is understood in the scholarly literature about whether the ACA Medicaid expansion affected longer-lasting changes in CHC patient insurance mix. This study's objective was to examine whether the ACA Medicaid expansion was associated with lasting increases in the annual percentage of adult CHC patients covered by Medicaid and decreases in the annual percentage of uninsured adult CHC patients at expansion-state CHCs, compared to non-expansion-state CHCs. This observational study examined 5353 CHC-year observations from 2012 to 2018 using Uniform Data System data and other national data sources. Using a 2-way fixed-effects multivariable regression approach and marginal analysis, intermediate-term policy effects of the Medicaid expansion on annual CHC patient coverage outcomes were estimated. By 5-years post-expansion, the Medicaid expansion was associated with an overall average increase of 11.7 percentage points in the percentage of adult patients with Medicaid coverage at expansion-state CHCs, compared to non-expansion-state CHCs. Among expansion-state CHCs, 39.8% of adult patients were predicted to have Medicaid coverage 5-years post-expansion, compared to 19.0% of non-expansion-state adult CHC patients. A state's decision to expand Medicaid was similarly associated with decreases in the annual percentage of uninsured adult CHC patients. Primary care operations at CHCs critically depend on patient Medicaid revenue. These findings suggest the ACA Medicaid expansion may provide longer-term financial security for expansion-state CHCs, which maintain increases in Medicaid-covered adult patients even 5-years post-expansion. However, these financial securities may be jeopardized should the ACA be ruled unconstitutional in 2021, a year after CHCs experienced new uncertainties caused by COVID-19.

Do Oral Health Services in Medical Offices Replace Pediatric Dental Visits?

In the United States, state Medicaid programs pay for medical and dental care for children from low-income families and support nondental primary care providers delivering preventive oral health services (POHS) to young children in medical offices ("medical POHS"). Despite the potential of these policies to expand access to care, there is concern that they may replace dental visits with medical POHS. Using Medicaid claims from 38 states from 2006 to 2014, we conducted a repeated cross-sectional study and used linear probability regression to estimate the association between the annual proportion of children in a county receiving medical POHS and the probability that a child received 1) dental POHS and 2) a dental visit in a given year. Models included county and year fixed effects and controlled for child- and county-level factors, and standard errors were clustered at the state level. In a weighted population of 45.1 million child-years (age, 6 mo to <6 y), we found no significant nor substantively important association between the proportion of children in a county receiving medical POHS and the probability that a child received dental POHS or a dental visit. Additionally, we found an almost zero probability (<0.001) that the reduction in dental POHS was at least as large as the expansion in medical POHS (full substitution) and a 0.50 probability that increased medical POHS was associated with an increase in dental POHS of at least 6.6% of the expansion of medical POHS. Results were similar when receipt of dental visits was examined. This study failed to find evidence that medical POHS replaced dental visits for young children enrolled in Medicaid and, in fact, offers evidence that increased medical POHS was associated with increased utilization of dental care. Given lower-than-desired rates of dental visits for this population, delivery of medical POHS should be expanded.

Impact of a Medicaid policy on preventive oral health services for children with intellectual disabilities, developmental disabilities, or both

BACKGROUND

Integrating preventive oral health services (POHS) into medical offices may ease access to care for children with intellectual and developmental disabilities (IDD). The authors examined the impact of state policies allowing delivery of POHS in medical offices on receipt of POHS among Medicaid enrollees with IDD.

METHODS

The authors used 2006 through 2014 Medicaid data for children with IDD aged 6 months through 5 years from 38 states. IDD were defined using 14 condition codes from Centers for Medicare & Medicaid Services Chronic Conditions Data Warehouse. The length of the state's medical POHS policy (no policy, < 1 year, 1 year, 2 years, 3 years, or ≥ 4 years) was interacted with an indicator that the child was younger than 3 years. The authors used logistic regression models to estimate the likelihood that a child received POHS in a medical office or in a medical or dental office in a given year.

RESULTS

Among 447,918 children with IDD, 1.6% received POHS in medical offices. Children younger than 3 years in states with longer-enacted policies had higher rates of receiving POHS. For example, the predicted probability of receiving POHS was 40.6% (95% confidence interval, 36.3% to 44.9%) for children younger than 3 years in states with a medical POHS policy for more than 4 years compared with 30.6% (95% confidence interval, 27.8% to 33.5%) for children in states without a policy.

CONCLUSIONS

State Medicaid policies allowing delivery of POHS in medical offices increased receipt of POHS among Medicaid-enrolled children with IDD who were younger than 3 years.

PRACTICAL IMPLICATIONS

Few children with IDD receive POHS in any setting. Efforts are needed to reduce barriers to POHS for publicly insured children with IDD.

Increased Dental Use May Affect Changes in Treated and Untreated Dental Caries in Young Children

INTRODUCTION

From 1999-2004 to 2011-2014, untreated dental caries prevalence decreased among US children aged 2 to 5 y, regardless of family income. Policies were concurrently initiated for children to increase access to preventive dental services in dental, primary, and community settings and to restorative care in dental settings.

OBJECTIVES

We aimed to examine 1) whether changes in prevalence and severity of untreated and treated caries between the periods varied by family income and 2) to what degree increased past-year dental visit (PYDV) contributed to the changes.

METHODS

We used data for 3,822 children in the National Health and Nutrition Examination Survey 1999 to 2004 and 2011 to 2014. Caries prevalence included prevalence of untreated caries with ≥1 decayed teeth (dt) and prevalence of treated caries with ≥1 filled teeth (ft). Caries severity included number of dt and ft among those with ≥1 dt or ft. We estimated changes in caries outcomes among low- and higher-income children with models-one controlling for sociodemographics and another controlling for sociodemographics and PYDV. Significant changes ( P < 0.05) becoming insignificant after controlling for PYDV provide insight on the contribution of PYDV to changes in outcomes.

RESULTS

Prevalence of untreated caries decreased for low- and higher-income children, with a slightly larger decrease for low-income children; dt decreased only for low-income children; and estimated decreases did not vary by model. An increase in prevalence of treated caries was observed only among low-income children but became minimized and insignificant after controlling for PYDV. Similarly, after controlling for PYDV, the increase in ft among low-income children lost significance, whereas the increase among higher-income children remained.

CONCLUSION

Untreated caries among children aged 2 to 5 y declined from 1999-2004 to 2011-2014, with larger declines among low-income children. While changes in PYDV contributed to increases in treated caries, particularly for low-income children, additional factors appear to have contributed to decreased untreated caries.

KNOWLEDGE TRANSFER STATEMENT

For young children, the degree and direction of changes in caries over the last decade varied by outcome measure (e.g., untreated or treated) and family poverty status. Examining the effect of increased dental utilization on changes in untreated and treated caries outcomes can help identify those policies that contribute to changes in these outcomes and highlight the potential role of the different caries assessment criteria used in dental offices versus those in a population-based survey.

Delivery of Preventive Oral Health Services by Rurality: A Cross-Sectional Analysis

PURPOSE

Integrating oral health care into primary care has been promoted as a strategy to increase delivery of preventive oral health services (POHS) to young children, particularly in rural areas where few dentists practice. Using a multistate sample of Medicaid claims, we examined a child's odds of receiving POHS in a medical office by county rurality.

METHODS

We used 2012-2014 Medicaid Analytic extract claims data for 6,275,456 children younger than 6 years in 39 states that allowed Medicaid payment for POHS in medical offices. We used county-level characteristics from the Area Health Resources Files, including a 3-level measure of county rurality. We used logistic regression to estimate a child's odds of receiving POHS in a medical office by county rurality, while controlling for other patient and county characteristics.

FINDINGS

POHS in medical offices were received by 7.8% of children. Rates of POHS in medical offices were higher in metropolitan (metro) counties (8.4%) than nonmetro adjacent to metro (5.8%) and nonmetro not adjacent to metro (4.3%). In adjusted analysis, children living in nonmetro not adjacent to metro (OR = 0.79, 95% CI: 0.64-0.99) and adjacent to metro counties (OR = 0.70, 95% CI: 0.59-0.82) were significantly less likely to receive POHS in medical offices than children living in metro counties.

CONCLUSIONS

In this study of POHS in medical offices among young Medicaid-enrolled children, we found POHS rates were lowest in nonmetro counties. Given barriers to dental care in rural areas, states should take additional steps beyond allowing Medicaid reimbursement to increase delivery of POHS in medical offices.

Impact of Medicaid Policy on the Oral Health of Publicly Insured Children

Objective Fluoride varnish (FV) applications among non-dentist primary care providers has increased due to state Medicaid policies. In this study we examine the impact of FV policies on the oral health of publicly insured children aged 2-6 years old. Methods Using three waves of the National Survey of Children's Health (2003, 2007, 2011/12), we used a logistic regression model with state and year fixed effects, adjusting for relevant child characteristics, to examine the association between years since a state implemented a FV policy and the odds of a publicly insured child having very good or excellent teeth. We compared children with public insurance in states with FV policies to children with public insurance in states without FV policies, controlling for the same difference among children with private insurance who were unlikely to be affected by Medicaid FV policies. Results Among 68,890 children aged 2-6 years, 38% had public insurance. Compared to privately insured children, publicly insured children had significantly lower odds of having very good or excellent teeth [odds ratio (OR) 0.70, 95% CI 0.62-0.81]. Publicly insured children in states with FV policies implemented for four or more years had significantly greater odds of having very good or excellent teeth (OR 1.28, 95% CI 1.03-1.60) compared to publicly insured children in states without FV policies. Conclusions for Practice State policies supporting non-dental primary care providers application of FV were associated with improvements in oral health for young children with public insurance.

From theoretical concepts to policies and applied programmes: the landscape of integration of oral health in primary care

BACKGROUND

Despite its importance, the integration of oral health into primary care is still an emerging practice in the field of health care services. This scoping review aims to map the literature and provide a summary on the conceptual frameworks, policies and programs related to this concept.

METHODS

Using the Levac et al. six-stage framework, we performed a systematic search of electronic databases, organizational websites and grey literature from 1978 to April 2016. All relevant original publications with a focus on the integration of oral health into primary care were retrieved. Content analyses were performed to synthesize the results.

RESULTS

From a total of 1619 citations, 67 publications were included in the review. Two conceptual frameworks were identified. Policies regarding oral heath integration into primary care were mostly oriented toward common risk factors approach and care coordination processes. In general, oral health integrated care programs were designed in the public health sector and based on partnerships with various private and public health organizations, governmental bodies and academic institutions. These programmes used various strategies to empower oral health integrated care, including building interdisciplinary networks, training non-dental care providers, oral health champion modelling, enabling care linkages and care coordinated process, as well as the use of e-health technologies. The majority of studies on the programs outcomes were descriptive in nature without reporting long-term outcomes.

CONCLUSIONS

This scoping review provided a comprehensive overview on the concept of integration of oral health in primary care. The findings identified major gaps in reported programs outcomes mainly because of the lack of related research. However, the results could be considered as a first step in the development of health care policies that support collaborative practices and patient-centred care in the field of primary care sector.

Barriers and facilitators in the integration of oral health into primary care: a scoping review

OBJECTIVE

This scoping study has been conducted to map the literature and provide a descriptive synthesis on the barriers and facilitators of the integration of oral health into primary care.

METHODS

Grounded in the Rainbow conceptual model and using the Levac et al six-stage framework, we performed a systematic search of electronic databases, organisational websites and grey literature from 1978 to April 2016. All publications with a focus on the integration of oral health into primary care were included except commentaries and editorials. Thematic analyses were performed to synthesise the results.

RESULTS

From a total of 1619 citations, 58 publications were included in the review. Barrier-related themes included: lack of political leadership and healthcare policies; implementation challenges; discipline-oriented education; lack of continuity of care and services and patients' oral healthcare needs. The facilitators of integration were supportive policies and resources allocation, interdisciplinary education, collaborative practices between dental and other healthcare professionals, presence of local strategic leaders and geographical proximity.

DISCUSSION AND PUBLIC HEALTH IMPLICATIONS

This work has advanced the knowledge on the barriers and facilitators at each integration domain and level, which may be helpful if the healthcare organisations decide to integrate oral health and dental services into primary care. The scoping review findings could be useful for both dental and medical workforce and allied primary healthcare providers. They could also guide the development of healthcare policies that support collaborative practices and patient-centred care in the field of primary care.
