Workforce Issues and Delivery of Oral Health Care Services in a Dental Home

Board takeaway

Access and equity

• Disadvantaged children bear disproportionate disease; improvements vary by race and income. Special health care needs complicate access.
• Low public reimbursement and missed appointments discourage participation. Pediatric dentist availability is associated with preventive utilization among Medicaid-enrolled children.
• Identify literacy, language, cultural, financial, transportation, and geographic barriers.
• Support shortage-area providers, Medicaid reform, workforce diversity, poverty reduction, education, and primary prevention.

Dental home: timing and continuity

• Establish as early as 6 months, and no later than 12 months.
• Provide comprehensive, continuously accessible, coordinated care adapted to development and family needs.
• Early visits enable individualized prevention; growing evidence supports caries reduction.
• Include referral capacity when medically necessary care exceeds the home’s capabilities.
• Periodically evaluate mobile and school programs’ effectiveness as dental homes.

Team roles and supervision

• Dentist: examine, diagnose, and establish the treatment plan, including prevention.
• Direct supervision: dentist physically present during care. Expanded teams can increase volume and efficiency.
• General supervision: supervising dentist absent from the facility.
  • The policy supports preventive services by licensed hygienists or nondentist providers after the supervising licensed dentist’s examination, diagnosis, and treatment plan.
• Community auxiliaries can educate families and coordinate services within the dental home.
• Partner with medical providers who see children early.

Workforce models: what evidence establishes

• Location and retention matter; private practice does not assure underserved-area placement.
• Alaska findings support improved utilization; Minnesota cases did not show comparable geographic expansion. International experience includes relocation toward less-remote practices.
• Historical New Zealand caries burden despite free care and dental therapy illustrates persistent disparities.
• Training varies: the source describes three-year Alaska dental health aide therapist (DHAT) training after high school; dentists typically complete four dental-school years after science prerequisites, plus at least two years for pediatric specialization.
• Comparable restoration quality within limited services and circumstances does not establish equivalent diagnosis, pathology, trauma care, pharmacology, behavior guidance, treatment planning, special-needs care, or long-term outcomes.
  • These are the policy's distinctions about scope and evidence; comparisons between locations are not controlled proof that a workforce model caused or resolved a disparity.
• Children with extensive disease may need sedation or general anesthesia; behavior assessment and advanced guidance require specialized knowledge and experience.
• Literature and reports are supplemented by expert opinion where evidence is unavailable; no formal certainty grades.

Policy priorities and evaluation

• Promote early homes, care/education funding, public-private partnerships, and rural/underrepresented recruitment.
• Study barriers and underutilization across medicine and dentistry.
• Research safe, effective, sustainable dentist-directed models; evaluate training duration, content, and outcomes before scope recommendations.
• Consult AAPD and state units when developing consequential pilots or policies.
• Use technology and teledentistry to extend access and quality within the dentist-centered model.

Common board traps

Answer aloud

How would you expand rural access?

Identify the local barriers first: distance, transport, affordability, language, available appointments, and capacity for treatment/referral.

• Expand a dentist-directed dental home through trained supervised teams, medical partnerships, community coordination, and teledentistry.
• Evaluate whether patients actually obtain continuing preventive and definitive care; adding providers or screening visits alone does not demonstrate improved access or outcomes.

Can an auxiliary provide prevention with no dentist onsite?

It may be appropriate under general supervision when permitted by applicable law and the provider's scope.

• In AAPD's model, the licensed supervising dentist first performs the examination, diagnosis, and treatment plan.
• Offsite prevention remains part of coordinated, dentist-directed care; this policy is not a blanket legal authorization for every auxiliary or procedure.
