Reconnecting Practicing Hygienists with the Nation's Leading Educators and Researchers.

Benefits of Medical-Dental Integration

Both patients and clinicians stand to gain under this model of care.

The United States Preventive Services Task Force recommends that children receive fluoride varnish applications when the first primary tooth erupts, usually at age 6 months to 1 year.1 The American Academy of Pediatric Dentistry suggests that first permanent molars receive dental sealants shortly after eruption, at about age 6.2 Unfortunately, in 2020, only about 52% of children enrolled in Medicaid received any kind of dental services.3 Indeed, in that same year, only 40,758 (1.99%) Medicaid enrollees under the age of 1 received a preventive dental treatment. In addition, only 957,692 (11.8%) of children ages 6 to 9 covered by Medicaid received dental sealants.

One of the primary reasons for this is that so few dentists will treat patients covered by Medicaid; while 38% is the national estimate, the number is highly variable from state to state and dependent on the methodology used to determine the estimate.4,5 On the other hand, primary care providers—including pediatricians, family physicians, advanced registered nurse practitioners, and physician assistants—do serve these vulnerable patients.6

The purpose of this paper is to suggest that the implementation of dental hygienists working in primary care practices is a smart strategy to improve access to dental care for patients covered by Medicaid and other vulnerable patients. It would also provide significant employment opportunities for dental hygienists.

Definition

Medical-dental collaboration and integration are not new to the oral health space. It is important, however, to distinguish between collaboration and integration.7 “Collaboration” refers to primary care and oral healthcare team members working together to improve the health outcomes of their patients; a good example is the primary care clinic staff providing preventive dental services and referring patients to a dental home.

“Integration” refers to oral health services provided by a dental team member within and/or embedded into the primary care medical team. This type of medical-dental integration is not a new concept. A number of states have dental practice acts that allow these kinds of activities by dental hygienists.8–10

Medical-Dental Integration In Action

Supported in part by a Health Resources and Services Administration (HRSA) Oral Health Workforce grant to the Florida Department of Health, a medical-dental integration project was implemented in Florida. Dental hygienists were placed in the pediatric clinic of a federally qualified health center (FQHC). Anecdotal evidence from several other FQHCs in Florida suggested this model would be a success; however, quantifying the results so they could be shared in addition to supporting the recommendation that other FQHCs should implement medical-dental integration were the goals.

We placed two medical-dental integration (MDI) dental hygienists in two pediatric clinics of the FQHC; another pediatric clinics served as a control site. Table 1 lists the services provided by the MDI hygienists.

The results were not surprising. Children seen by the MDI hygienist received fluoride varnish applications and dental sealants earlier than children who were simply referred to the dental clinic by the pediatric clinic. What was surprising was that the dental clinic failure/no-show rate for children referred to the dental clinic was less than half of those children simply referred by the pediatric clinic staff. A detailed report with supporting data is in preparation for journal submission. Several papers that describe best practices in implementing medical-dental integration programs have been published.11–15

Medical-dental integration provides new career opportunities and pathways for dental hygienists to work at the top of their scope of practice.

Barriers to Implementation

Some barriers do exist to medical-dental integration that can be relatively easy to overcome. Sharing of health information rarely occurs between medical and dental providers without a fully integrated medical and dental electronic health record. Primary care practitioners traditionally see the mouth as the property of dentists and may be uncomfortable or uninterested in adding another procedure to a busy practice model. Medical and dental care are seen by the public/patients as separate. Limited oral health education is provided to medical professionals. However, good efforts have been made to overcome these barriers.

One of the primary barriers to medical-dental integration is restrictive dental practice acts that prevent dental hygienists from being employed and supervised by a primary care practice.16,17 This model works in Florida FQHCs because the dental hygienist is under general supervision of a dentist within the FQHC system and because the FQHC can bill for the dental hygienist’s services.

This is why the efforts of the American Dental Hygienists’ Association (ADHA) to implement direct access for dental hygienists should be broadly supported. According to the ADHA, direct access refers to the ability of dental hygienists to:18

  1. Initiate treatment based on their assessment of a patient’s needs without the specific authorization of a dentist
  2. Treat the patient without the presence of a dentist
  3. Maintain a provider-patient relationship

table 1Conclusions

Lack of access to quality dental care is a critical problem for many individuals, especially low-income populations and people of color. These oral health inequities have serious consequences including interfering with school learning and performance and negatively impacting the oral health-systemic health link. Medical-dental integration is one way to improve access to preventive dental services and referrals to a dental home. In addition, medical-dental integration provides new career opportunities and pathways for dental hygienists to work at the top of their scope of practice. Medical-dental integration is good for both patients and dental hygienists.
