Is There a Shortage of Hygienists?
  • 158,000 hygienists in 2004
  • Expected to grow (gt27) by 2014
  • Hygienists leave profession
  • ADHA says that, due to supervision requirements
    in many states, hygienists must locate where
    dentists are, so they are maldistributed as well

Labor Statistics, http//
Dental Safety Net Needs Expanding
  • No dental emergency rooms
  • Serves less than 10 of 82 million underserved
    people (Bailit, JADA, 2003)
  • Critical safety net consists of community health
    centers, hospitals, dental and hygiene schools,
    school-based health centers

State Strategies for Rural Areas
Supply, Redistribution Strategies
  • State loan repayment programs for rural DDs and
  • Licensing strategies
  • Foreign dentists in safety net settings
  • Licensure by credential
  • Licensure after service, residency
  • Payment incentives (higher Medicaid fees in rural
    areas, clinics, e.g. Utah)

Ways to Increase the Supply...
  • Exempt retired dentists from liability for
    volunteering to work in vans, CHCs, RHCs
  • Establish rural clinical training sites or
    preceptorships for dental and hygiene students
  • Work with rural schools and colleges to recruit
    dental and hygiene students
  • Establish scholarships for rural dental students

More Ways to Increase the Supply...
  • Help add dental capacity in clinics, CHCs
  • Start a revolving loan fund for establishing
    rural practices
  • Enhance sales of rural practices with grants for
    equipment upgrades
  • Play matchmaker to help retiring rural dentists
    sell their practices

More Ways to Increase the Supply...
  • Teledentistry via email or video saves trips
  • Mobile dental vans
  • expensive, waste disposal problems
  • continuity of care and follow-up problems
  • hard to staff, but sometimes the only option
  • Mobile dental units
  • rotate to locations like schools, nursing homes
  • easier to staff but smaller capacity

State Action on Workforce
Integrating Oral Health into Primary Care
  • Dentist to population ratio shrinking PCP to
    population ratio is growing
  • Prevention is cheaper, better
  • More frequent, earlier use of primary care
    services for young children and underserved
  • Patient trust and comfort (fear factor)

Oral Health Services Medical Professionals Can
  • Oral health evaluation (visual screening for
  • Application of fluoride varnish
  • Patient and parent education
  • Dispensing oral health supplies
  • Toothbrushes, toothpaste, xylitol gum
  • Limited prophylaxis, antimicrobials
  • Case management, referral

State Action
  • Curricula or training for primary care providers
    (AL, AR, CA, KY,ME, NH, NV, NY, OR, SD, WA, WI)
  • Medicaid payment for MDs to provide fluoride
    varnish (13 states)
  • Joint initiatives for screening and referral (SC)
  • Source Survey of Medicaid/SCHIP Directors of
    Administration conducted by NASHP, 2008

Challenges in Integration
  • Involve dentists in training MDs, RNs, NPs
  • Link medical and dental homes
  • Reimbursement through public and private
    insurancemake it universal
  • Differences in fee-for-service and managed care
  • Diffusion of idea change practice patterns

Trends in dental hygiene
  • Gradual loosening of supervision, expansions in
  • Movement towards providing services in public
    health settings
  • Bulk of hygienists still practice in traditional
    settings maldistributed as are dentists

Supervision and Payment for Hygienists
  • General supervision in 45 states in dental office
    or some settings
  • Direct access to patients in some settings in 22
    states (AZ, CA, CO, CT, IA, KS, ME, MI, MN, MO,
    MT, NE, NH, NM, NV, NY, OK, OR, PA, RI,TX, WA)
  • Medicaid can reimburse hygienists directly in 12
    states (CA, CO, CT, ME, MN, MO, MT, NM, NV, OR,
    WA, WI)

Current Workforce Proposals
  • Proposals to expand scope or loosen supervision
    of hygienists
  • 7 states have proposals far along or completed in
    the legislative process (MA, WI, MN, MT, CA, OH,
  • Proposals to develop new dental practitioners
  • 3 states have proposals far along in the
    legislative process (MN, MI, MA)
  • 11 states are discussing proposals (CO, ME, NM,
    CA, FL, TX, OH, OR, KS, CT, PA)

  • RDH-ECP are hygienists in community settings
    (Head Start, schools, health depts, safety net
    clinics, and long-term care facilities)
  • Hub and spoke system--general supervision
  • 55 hygienists have ECPs 25 working in community
  • In 2007, settings changed
  • ECP I hygienists can serve wider range of
  • ECP II hygienists can serve a wider range of
    elders and adults with special health care needs
  • Hygienists can apply fluoride varnish in
    community settings

    to do these
  • Developing payment structures and charting
    systemwho will be charged and for what?
  • Start up loans--mobile equipment runs 25K
  • Building the business
  • Strategies vary by setting and community
  • Diversification helps mitigate risks
  • Outreach to consumers and health care systems

Structure of RDHAP Practice
  • Laws/Regulations
  • Allow practice, but also limit it
  • Title 22/OBRA vague construct creates confusion
  • Care systems
  • RN, LTC homes, Schools, Clinics, etc.
  • Payment systems
  • Denti-Cal, self pay, insurance companies
  • Anti-competitive practices of dentists
  • Lawsuits, exclusion from institutions, slanderous
    marketing fear-mongering, betrayal of trust,
    exclusion of suppliers or dentists who

What isnt Happening in States, but Needs to
  • Disease management approach for dental caries
  • Caries is infectious, recurs
  • Change to primary care model in dentistry
  • Private practice model organized around surgery,
    restorations, maximizing income
  • Primary dental care would involve screening, risk
    assessment, case management, referrals

And, Investment in Upstream Strategies
  • Sealant programs serve too few kids
  • ME programs reach about ½ the schools (better
    than many states)
  • Water fluoridation, in some areas its stalled or
    retreating, despite sound science, low cost
  • Education and outreach for at-risk families

Progress on New Provider Models
Existing Models
  • Dental therapistNew Zealand model
  • Called dental health aid therapist in AK in use
    in 53 countries
  • Oral health therapistnewer 3-yr program combines
    dental therapy and hygiene
  • Expanded Function Dental Assistants
  • Underutilized can expand productivity and
    profitability of dental practices
  • For state licensing, scope info, check

EFDAs are Underused
  • Only 16 states train and license Expanded
    Function Dental Auxiliaries
  • EFDAs are dental extenders that make practices
    more profitable
  • Increase efficiency in large practices, clinics
  • Most dentists not trained to use them
  • RWJ grant to PA may help other states replicate
    training and practice models

Evidence on EFDAs
  • Lotzkar et al, JADA. 82(1971)
  • Dental teams with 4 EFDAs and 1 dentist increase
    productivity over base-line performance by 110
    to 133 compared to 3 EFDAS and 1 dentist with
    productivity increase over base-line performance
    of 62 to 84
  • Abramowitz et al, JADA. 87(1973)
  • As more auxiliaries added to dental team,
    relative costs per unit of time worked decreased
    from 2.54 to 2.26 and net income for the
    dentist increased from 28,030 to 39,147
  • Lobene et al, The Forsyth Experiment An
    Alternative System for Dental Care (Cambridge,
    MA Harvard University Press, 1979)
  • Optimal setting of 1 dentist supervising 2
    hygienist-assistant teams provided calculated
    annual net of the gross income to practice of
    35.3 and 47.0 by welfare and usual fees,
    compared to practice with 1 dentist and 1 team
    that had calculated expenses of 28.7 and 42.9
    annual net of gross income to the practice

New Models for Dental Providers
  • ADA model Community Dental Health Coordinator
    (similar to Primary Dental Health Aides in
  • ADHA model Advanced Dental Hygiene Practitioner
  • Pediatric Oral Health Therapist (a dental
    therapist specializing in kids)

Community Dental Health Coordinator
  • Prevention education, fluorides, sealants
  • Treatment gingival scaling, polishing
  • Restoration atraumatic restorative therapy
  • Supervision direct or indirect for services,
    general supervision for patient education

Advanced Dental Hygiene Practitioner
  • Prevention comprehensive services
  • Treatment manage periodontal care, prophylaxis,
  • Restoration simple restorations, extractions
  • Supervision general supervision or unsupervised
    in collaborative practice, or private dental

Dental therapists
  • Prevention fluoride treatments, sealants
  • Treatment x-rays, prophylaxis, gingival scaling
  • Restoration simple restorations, stainless steel
    crowns, extractions
  • Supervision general supervision under standing

Cost Effectiveness of Dental Therapists in Canada
  • Dental therapists reduced the number of medical
  • Transportation costs dropped dramatically
  • Dental therapists can deal with most emergencies
  • Dental therapists make dentists visits more
    productive, triage patients, take x-rays, arrange
    for medications before dentist arrives
  • Quality of care studies determined that the
    procedures performed by dental therapists are of
    equal or greater quality than those performed by

  • How do We Move Forward on New Workforce Models?

3 Requirements for Policy Change
  • Shared perception of the problem
  • Public agreement communication frames issue,
    raises priority
  • Political support
  • Broad-based support, all powerful groups or
    actors involved
  • Viable policy solution
  • Workable, timely, affordable, proven

Problems lead to Solutions
  • Provide education to parents, incentives,
  • Fluoridate water, fund sealant programs, school
    based care
  • Recruit dentists, pay more to treat low income
    patients, fix hassles
  • Parents not getting kids to the dentist
  • Areas lack fluoridated water, sealant programs
  • Too few dentists locate near, serve low income

Consider Attitudes in Building Support for
  • Low income parents are irresponsible No
  • Some oppose fluoride, more services to the poor
    (equity issues)
  • Dentists are rich already, wont come, dont
  • Provide education to parents, incentives, fines
  • Fluoridate water, fund sealants, school-based
  • Recruit dentists to underserved areas, pay more,
    fix hassles

Attitudes about Dentists
  • They feel no obligation to the community.
  • Uncooperative, greedy, lacking in empathy.
  • The most territorial mammals on the face of the
    earth, except maybe dogs.
  • Dont want to care for poor people but they
    dont want us to either.
  • Source S. Gehshan, T. Straw, Access to Oral
    Health Services for Low Income People, National
    Conference of State Legislatures, 2002.

Organized Dentistry Does Care
  • voluntary programs to deliver free careare no
    substitute for fixing the Medicaid program.
  • We need to get more private dentists
    participating in Medicaid. (Roth, 3/27/07)
  • Active on many issues (SCHIP dental,
    fluoridation, Title VII, dental issues in IHS,
    CMS, HRSA programs)

Important Steps
  • State and local policy communities come to
    consensus, not national groups
  • Focus on the underserved, not providers
  • Communicate solutions, dont assume people
  • Seek investments from foundations, governments

Important Partners
  • PayorsMedicaid, SCHIP, private insurers,
  • CoalitionsProvider associations, dental/ medical
  • Legislators, local and state agency leaders
  • Universities, training programs
  • Safety net clinics, rural providers
  • Foundations

Ideas for groundwork
  • Estimate impact of new providers on private
    dental practice, safety net clinics
  • Develop financing options to support them,
    dentist supervisors, and facilities where they
  • Target new providers to specific settings
  • Data collection to monitor supply, demand
  • Establish multi-state collaboratives

Legal and Regulatory Groundwork
  • Establish manpower pilot authority (CA)
  • Consider new regulatory structure for auxiliaries
    (WA, NM, IA, CT)
  • Examine ban on corporate practice of
    dentistryrestricts choices for dentists, and
    options for communities
  • Examine dental practice actmay need safety net

Why Dentists Oppose Midlevels
  • Would create a two-tier system of care
  • Theres no shortage of dentists
  • Its illegal for non-dentists to do dentistry
  • They would jeopardize patient safety
  • Inefficient if they practice independently
  • They would take patients away from private

Answering Those Concerns
  • We have 3 tiers now (private, public, none)
  • Documented shortages in many areas
  • States regulate all health professionals,
    including dentists, to protect public safety
  • Efficient business models can be developed
  • Private dentists dont treat 1/3 of the public
    wont lose business

What dentists see
Dental Economics
  • About 55 from insurance, 45 cash
  • Very sensitive to downturns in the economy
    experience with oversupply
  • Overhead averages about .60-.65 of each dollar
  • Dentists have more to gain than lose from new
  • About 45 of patient visits are for hygiene

  • Source Albert Guay, Dental Practice Prices,
    Production, and Profit, JADA, Vol. 136 (March
    2005), 359.

Concurrent Steps to Create New Providers
  • Curriculum development, faculty training,
    recruiting students
  • Accreditation
  • Legislation establishing new providers issue
    enabling regulations
  • Licensing or credentialing process

System Questions
  • How to limit opposition and ensure new providers
    improve access?
  • License them only in dental HPSAs?
  • License in safety net settings only?
  • Enlist physicians, hospitals
  • How to involve and benefit dentists?
  • Develop referral networks, placement sites
  • Legal responsibility, and payment, for
    supervising, collaborating with, new providers

Lessons Learned from theMedical Field
Nurse Practitioners
  • Models created by leaders in 1960s (Commonwealth
  • Nurses opposed them (too medical)
  • Studies done on quality, cost effectiveness
  • Needed professional home educational program,
    faculty leaders (RWJ )

Nurse Practitioner Workforce Growth

Organization of Nurse Practitioner Faculties
Analysis by the Center for Health Professions,
UCSF, 2004.
Demonstration programs were mostly rural (RWJ )
  • UC Davis, rural physicians in home towns were
    clinical preceptors
  • Utah Valley Hospital, rural clinics, back-up by
    ER docs
  • Tuskegee Institute, mobile vans, fax/ phone to
    supervising physicians
  • Frontier Nursing Service, KY, rural maternity
    care, physician back-up

Physician Assistants
  • Leader at Duke envisioned PAs as primary care
    providers, from roots in military medical corps
  • National assoc. and accrediting body estd early
    on (RWJ )
  • Developed separately from NPs
  • Less controversial, yet similar to NPs
