CHICAGO, July 25, 2012—The American Dental Association today released six reports examining the economic viability of three models of so-called "midlevel" dental providers, the Dental Health Aide Therapists (DHATs) currently providing care in Alaska Native territories, the Dental Therapists (DTs), currently working in Minnesota, and the proposed but as yet unrealized Advanced Dental Hygiene Practitioner (ADHP).  The reports raise serious questions about whether these midlevel provider models can sustain themselves economically.

"These studies represent a new way of examining whether midlevel providers are an economically viable way to improve access to dental care for underserved populations," said ADA President William R.  Calnon, DDS.  "They are a first step, and not the last word.  But certainly, lawmakers and public health authorities should consider the factors examined in the studies carefully before rushing to create dental providers that may be unable to fulfill their intended purpose of reducing oral health disparities."

The studies, performed by ECG Management Consultants, examine practice parameters in five states where adopting one or more of these models has been under discussion in the legislature or the public health community.  ECG produced separate reports for the five states, Connecticut, Kansas, Maine, New Hampshire and Washington.  A five-state summary report also is available. 
ECG based its modeling on the length and cost of training of each midlevel position, operating costs, likely salaries, academic debt, and projected revenues. Researchers considered each model in the context of various combinations of public, sliding-scale, and private fee schedules.  (The fee schedules varied by state.)

Of the 45 scenarios modeled (three payer mixes for each of three practice models in five states), only five indicated positive net revenues, ranging from $8,000 in Kansas to $38,000 in Connecticut, assuming a 50/50 mix of public and private fees.  Four positive net revenue scenarios involved the Dental Health Aide Therapist model; one involved the Dental Therapist model.  The other 40 scenarios showed net losses ranging from $1,000 for a DHAT operating on a 50 public/50 private mix in Washington to $176,000 for an ADHP practicing in the same state, assuming a 75/25 public/sliding revenue mix.

"It is critical to understand that oral health disparities are a complex set of problems requiring an integrated set of solutions," said Dr. Calnon.  "Medicaid reforms, community water fluoridation, oral health education and helping people overcome cultural, geographic and language barriers are critical components of this.  The ADA believes that allowing nondentists to perform irreversible surgical procedures is the wrong way to go.  And based on these studies, midlevel dental providers would in most settings be unable to generate sufficient revenue to sustain themselves absent a continual source of financial underwriting.  Given the current budget constraints at every level of government, and the already insufficient financing for dental care in most states, midlevel providers do not appear to be viable.

 "Certainly, this research is not all-encompassing. But to our knowledge, no one has considered the question this comprehensively. The ADA encourages all stakeholders to study these models comprehensively, to avoid wasting constrained resources on programs that ultimately are not sustainable. We welcome others who are interested in breaking down barriers to oral health to join us in delving further into how best to maximize limited available resources-and advocating for increased resources-to improve the oral health of the tens of millions of Americans-including as many as one-quarter of the nation's children-who live without adequate access to regular dental care."

About the American Dental Association

The not-for-profit ADA is the nation's largest dental association, representing 157,000 dentist members. The premier source of oral health information, the ADA has advocated for the public's health and promoted the art and science of dentistry since 1859. The ADA's state-of-the-art research facilities develop and test dental products and materials that have advanced the practice of dentistry and made the patient experience more positive. The ADA Seal of Acceptance long has been a valuable and respected guide to consumer dental care products. The monthly The Journal of the American Dental Association (JADA) is the ADA's flagship publication and the best-read scientific journal in dentistry.
