Q&A: Dental Hygienist Opens Up for National Dental Hygiene Month

As October comes to an end, so does the national observance recognizing the need and importance of dental hygiene. For this Q&A, one of our own registered dental hygienists (RDHs) opens up about how she came to this career path and why it is invaluable to the oral health care system.

Let's dig in with Laura Skaret, RDH, BSDH | Project Manager, Safety Net Solutions | DentaQuest Institute

Q: Why did you decide to become an RDH?

A: My mom is a dental hygienist, and I got my first job at her office as a dental receptionist and then later was trained on the job to work as a dental assistant. I loved my experience as an assistant and found the work we did fascinating – including the devastating results of dental disease. I saw the cycle of dental disease first hand:  teeth would need small restorations, then larger restorations, then root canals, then crowns, and even sometimes implants. I knew I wanted to focus my career on helping patients prevent and properly manage dental disease rather than repairing the damage after it occurs.

We had a pamphlet in the office that said that enamel was far more valuable than gold (referring to a gold crown).  I found that to be such a thought-provoking and accurate concept.  It’s also similar to the old familiar adage, “an ounce of prevention is worth a pound of cure.”  That couldn’t be more true in the dental field.

Q: Why are hygienists important in the care team? 

A: Dental hygienists are patient advocates. When explaining the dental disease process to patients, I always tell them that my job is essentially to keep them out of the dentist’s chair, but I can only do so much without their buy-in.  Due to the nature of plaque biofilm, the daily care that patients do for their own mouths is far more important than the work that we do in one hour with them at the dental office. Patients go to the dental office maybe two to four times per year, however 365 days a year they are responsible for managing their own oral health.  This means our most important role is to educate and motivate our patients to improve their daily oral health habits. 

Q: What has been your greatest accomplishment or most proud moment in relation to working as an RDH?

A: I’ve realized that it’s not only what you do, but the way that you do it that can make an impact.  I always try to be very kind and compassionate to the questions and concerns of my patients. I’ve had several patients who were terrified of coming to the dental office when I first met them. Years of neglecting their mouths and avoiding the dentist would bring them to our office in a lot of pain and in need of quite a bit of dental work. In addition to using a gentle technique and local and topical anesthetics, I try to help them feel more comfortable by talking them through everything I’m doing or telling them stories to get their mind off of the situation. Sometimes it’s helpful to listen to their story to find out why they have a fear, affirm their past concern, and then assure them that won’t happen today. 

When those patients then continue to come in regularly, you know you’ve not only made a difference for their oral cavity, but for their life as well.  I had one patient who needed lengthy measures to address advanced decay and periodontal (gum) disease.  After we completed her first three visits of needed periodontal therapy, she actually sent a card to my office to thank me for helping her overcome her fear of the dentist.  With a more manageable level of fear, she was able to get the care she needed to restore her smile, which gave her back her confidence.

Q: How does your professional background impact/influence/help you in your DentaQuest Institute (DQI) role?

A: My primary role at DQI is as a project manager for Safety Net Solutions (SNS), a DentaQuest Institute program. Safety Net Solutions helps safety net dental clinics adopt targeted business management best practices.  Our focus is to ensure that these dental offices can maintain financial viability to stay open and provide access to care for the underserved. We also help ensure that they understand their capacity and can maximize access to care by optimizing their productivity.  

My previous experience of working in all areas of the dental office (receptionist, chairside with the dentist, and then also as a hygienist) means I have very comprehensive knowledge of how dental offices work, from scheduling appointments, to managing supplies and inventory, to managing the patient’s care experience, to dealing with dental equipment and instrument shortages. Basically, I can understand and relate to almost any concerns our SNS clients have.

Q: Why do you continue private practice once a week? 

A: Although you can technically keep your annual dental hygiene license “active” by simply paying the license fee each year, I want to keep it active with actual patient care, as well. Also I continue to practice because I love the work!  I love working with patients and helping them improve their oral health. I also believe this helps me stay relevant and engaged with my SNS clients and their common concerns. 

Q: What is one message you hope to impart to anyone interested in becoming an RDH?

A: Hygienists are super important members of the care team! As policy changes and we move forward with accountable care organizations and pay for performance insurance reimbursement models, I think the role dental hygienists play in preventing and managing disease will be brought even more into the forefront. When finances are attached to healthy patient outcomes, dental care teams will attach an even higher value to dental hygienists. 

Also, there is a massive shortage of dental professionals – and dentists in particular – nationwide. Maximizing the use of preventive modalities such as sealants, fluoride varnish, and silver diamine fluoride will help address access gaps where dentists are hard to come by, like rural areas.  Of course, we will never stop needing the education and skills of a dentist, but if we can reduce the demand for the skills of a dentist by reducing the dental disease burden, we can help minimize the gap in access to oral health care.

‘Action for Dental Health’ in Congress

While we all paid close attention to health care in the Senate last week, the House Energy and Commerce Committee made a critical, yet mostly overlooked step to advance oral health for at-risk populations.

On July 27^th, the Committee unanimously passed HR 2422, or the Action for Dental Health Act of 2017. This bill calls for Congress to authorize additional oral health promotion and disease prevention programs to help at-risk populations struggling to obtain appropriate oral health care.

The bill points out that more than 181 million Americans will not see a dentist, but almost half of people ages 30 and older have some form of gum disease and nearly a quarter of children under age 5 already have cavities. 

As we at DentaQuest well know, caries is the most prevalent chronicdisease among children and can be prevented. What’s more, we see time and again that Americans of all ages are in desperate need of access to oral health care - Missions of Mercy like the one in Wise County, Va., is a great example. Both the Washington Post and The New York Times covered the July event, for which thousands of people come from miles away and lineup for hours and even days just to get access to dental and other services.

If this new legislation passes through Congress, the Centers for Disease Control and Prevention will award grants and collaborate with states, counties, public officials, or other stakeholders to implement a variety of initiatives.

These activities could include oral health programs that:

·         more broadly use portable/mobile dental equipment;

·         facilitate the establishment of dental homes;

·         eliminate geographic, language, cultural, or other barriers to care;

·         reduce the use of emergency departments for dental conditions; and

·         provide dental care to nursing home residents.

It is exciting to see bipartisan support for dental care initiatives that have tremendous impacts on the oral and overall health of patients. This type of work will drastically improve the health of Americans. And it has the ability to address the estimated $2.6 billion in free care that dentists currently deliver, as well as the nearly $2.1 billion spent on dental cases in hospital emergency departments – 80 percent of which could be treated in a dental office for roughly $4 million total, according to the bill.

Bipartisanship like this must continue and we urge legislators to make oral health a critical component of any health reform legislation that passes through this Congress. 

Why are dentistry and oral health care practices seemingly easy to question?

The topic of evidence in dentistry and oral health care has been in the news a lot recently, with articles like this column in the New York Times by a professor of pediatrics.

In his column, Aaron Carroll discusses the differences he sees between his own and his wife’s dental journeys, as well as what little rigorous research has been done to support certain generally recommended dental practices.

What is interesting is that articles like this one and the popular flossing article from the Associated Press, among others, imply that recommendations made by dentists are based solely on limited or weak evidence – or worse, based simply on what the dentist will get paid for by an insurance company.

They also leave readers feeling that plaque removal and cavity prevention/treatment are the only elements necessary to address for good oral health.

Ultimately, Carroll suggests in his column that while lack of evidence doesn’t mean oral health prevention efforts don’t work, we should invest in research to ensure that those things we do are evidence-based.

For those of us in the business of improving oral health, we couldn’t agree more with that conclusion. But let’s take a closer look at some of the points that may have gone overlooked by recent press coverage.

We know that evidence something works for populations doesn’t directly translate into solutions for a specific individual – that is in fact why Carroll and his wife have such dramatically different dental journeys.

Carroll notes he has had just one filling in his life and doesn’t religiously care for his mouth, while his wife has “more fillings than [he] can count” but is fastidious in her oral care routines.

This underscores two important points:

1. Every person is different. Individualizing care is critical to improved oral health.

While evidence-based research informs standards of care, it is the dental team that must develop the best care plan for any given person’s situation. That is why DentaQuest invests in the development and adoption of evidence-based care protocols that focus on prevention, early intervention and disease management.

Our investments in disease management and risk assessment help provide dental teams with the knowledge and tools they need to best serve their patients.

For instance, across a five-year period, the DentaQuest Oral HealthCenter demonstrated that risk assessment and intense preventive efforts (including sealants and fluoride varnish) directly resulted in a reduction in the need for invasive surgical procedures.

Sealants are one of the most cost-effective strategies for protecting teeth, as noted in another recent New York Times column. This is because they provide a physical barrier against cavities. They can even be applied to teeth that are just starting to show signs of new cavities, and stop them from getting bigger.

The best time to seal a tooth is immediately after it erupts in the mouth, and so the DentaQuest Oral Health Center strives to set aside extra time at visits for children ages 6 and 11 since the permanent molars are usually erupting at that time. It is also why the DentaQuest Foundation collaborates so closely with school-based health alliances working to improve access to oral health care – and sealants – among children in grade school.

Additionally, with a patient population of over 10,000, the DentaQuest Oral Health Center works in collaboration with the DentaQuest Institute to refine strategies that make patients healthier. And when these best practices are implemented, they actively improve peoples’ health.

2. Prevention and oral health improvement do not take place solely in the dental chair.

Preventive dental visits provide an important opportunity for people to check in on their oral health habits and get evaluations for early signs of not just dental disease, but also chronic diseases like diabetes and hypertension.

Most of us spend two hours a year in a dental office. And, if we are to reconsider the benefit of two annual preventive visits as Carroll suggests, some of us might end up spending even less time with a clinician. So what about the other 8,758 hours?

The differences in the oral health of Carroll and his wife are not because he brushes with an electric toothbrush every day or because she is doing something “wrong” in her routine. Oral health care is more than just brushing and flossing. In fact, it is about more than your teeth and gums.

To make an impact, we have to take a look at how we pay for oral health care, how our public policies enable it, and how our communities prioritize it, in addition to how we provide it.

Addressing just one of those will not improve oral health care on the larger scale or reduce health care costs, as Carroll aims to do with his recommendations. We know oral health care is indeed critical for overall health. This is why we at DentaQuest look far beyond the dental chair.

For example, as part of Oral Health 2020, the DentaQuest Foundation is investing in efforts to incorporate oral health into the primary education system. Oral health education, screenings, assisted referral, and delivery of preventive care through our schools provide equitable, reliable entry into long-term oral health care.

DentaQuest also champions efforts to include innovative financing models for dental in person-centered approaches to care enabled by the Affordable Care Act (ACA).

Over the last decade, we’ve seen significant movement to transform our health care system into one that improves quality, lowers costs, and makes people healthier. In fact, on the medical side the Triple Aim is starting to be supported by alternative payment and care delivery models that are person-centered and focus on prevention.

Why did that happen? Because experts and advocates knew there had to be a better way forward for a healthier America.

The same is true for oral health. We are beginning to see that it is possible to live in a world where optimal oral health is the expectation, not the exception. We must continue to invest the same transformative energy into improving the oral health of all because you cannot have optimal overall health without optimal oral health.

 

What AP Didn’t Mention about Flossing

The recent flurry of news regarding the benefits of dental floss has left out an important point of view: while the evidence of flossing’s medical benefits may be weak, the evidence that it is pointless or harmful is even weaker. What’s more, flossing is an inexpensive oral hygiene practice accessible for people most in need of improved oral health.

But let’s break this down.

The Associated Press reported:

The evidence for flossing is "weak, very unreliable," of "very low" quality, and carries "a moderate to large potential for bias." … One study review in 2011 did credit floss with a slight reduction in gum inflammation — which can sometimes develop over time into full-fledged gum disease. However, the reviewers ranked the evidence as "very unreliable."

But the study review authors actually noted:

There is some evidence from twelve studies that flossing in addition to toothbrushing reduces gingivitis compared to toothbrushing alone. There is weak, very unreliable evidence from 10 studies that flossing plus toothbrushing may be associated with a small reduction in plaque at 1 and 3 months.

What is important to note here is:

1. The "weak, unreliable" language actually references the evidence that flossing specifically reduces plaque, not gum disease. But more importantly, the language used comes from a different lexicon than we use every day. “Weak, unreliable, low quality” all sound like common terminology, but in the research world, this type of language doesn’t indicate the science shouldn’t be believed. The terms actually may reflect that study authors left out some details (such as the exact method of randomizing people) that the study reviewers could not confirm, not that the research is bad. 
2. The fact the review of studies could not prove plaque reduction at 1 and 3 months is very likely because tooth decay and gum disease are slow progressing issues that would require multi-year studies. It may also be because the standard for measuring plaque reduction only scores visible surfaces, so plaque may be reduced on non-visible surfaces such as directly between teeth.
3. In March 2015, the same study review linked above also determined: the very low evidence for the efficacy [of flossing], however, does not preclude the use of floss. For instance, in inter-dental situations that only allow for the penetration of a string of dental floss, floss is the best available tool.

When the U.S. government removed flossing from its 2015-2020 Dietary Guidelines, it did so because the strength of published studies regarding the effectiveness of flossing were admittedly weak, as the AP reports. The studies were generally short-term with a small number of participants due to the cost of running what constitutes high-quality clinical trials. 

Aside from cost, a clinical study comparing patients who did and did not floss would also mean exposing and even encouraging control group patients to worsen their oral health – and watch as it happens without intervention. In the research world, this is considered unethical. We don’t allow people to develop diseases as part of research, and that helps protect every patient in the United States.

According to dental experts including the DentaQuest Institute’s Dr. Brian Nový, Director of Practice Improvement, the lack of long-term clinical trials is also because there is already significant scientific evidence indicating how cavities form and how to prevent them.

Clinical trials don’t investigate how teeth decay, they examine new types of interventions. Oral health experts thus have relied on evidence extrapolated from shorter term studies as well as years of clinical experience and practice standards.

We know the easiest way to prevent cavities is to keep your mouth clean and minimize plaque, and that premise is incorporated into many clinical trials because it is accepted as standard oral hygiene practice. 

In one small study out of the University of North Carolina Chapel Hill, researchers randomized 119 adults who already had gum inflammation. After two weeks, they found the group that only brushed achieved a 35 percent reduction in bleeding sites between teeth, while the other groups who brushed and used floss achieved “dramatic reductions of about 67 percent” – almost double the improvement.

While small, this particular study correlates with the evidence dentists see every day among their patients – flossing creates a healthier mouth and less disease.

“The real problem is that the modern American diet is full of refined carbohydrates, which has changed the type of plaque that forms on our teeth,” Dr. Nový notes. “It is much stickier and more dangerous and everyone should want to keep it off their teeth if they want to avoid dental problems.” 

Tooth decay and gum disease can occur anywhere that food debris and plaque accumulate. The ideal spot is between teeth since it is difficult for the toothbrush bristles to remove or even attempt to remove any of the debris. That is why flossing or use of an inter-dental brush is recommended - to best remove the food debris that would remain between the gums and the teeth where a toothbrush cannot fit.

In response to the AP article, Dr. Robert Compton, Chief Dental Officer, DentaQuest and President, DentaQuest Institute, recalled an observation frequently used by health experts: the evidence to support the effectiveness of parachutes is weak because there has never been a double-blind randomized controlled trial to demonstrate effectiveness. That does not mean that parachutes are not effective. It just means no one has conducted expensive research that compared the effectiveness of somebody jumping with a parachute to a control group jumping without one.

“There's not enough money to conduct research for cancer cures and treatment for heart disease,” said Dr. Compton, adding, “if there isn’t funding for life-saving interventions, there will likely never be funding for the kind of research the AP reports would be required to sanction flossing as a recommended oral health habit.”

While flossing may be a habit that is difficult for people to connect with, it definitely helps remove food debris from hard-to-reach places. It is a low-cost, easy-to-use intervention that has the potential to improve the oral health of many, in particular those already suffering from dental disease.

This, among other reasons, is why oral health clinicians Tim Iafolla of the National Institutes of Health and Wayne Aldredge of the American Academy of Periodontology both told the AP they maintain flossing is important.

And Dr. Nový adds, “It comes down to personal hygiene. Do you want to have bad breath, and puffy bleeding gums, or do you want people to notice your smile because it’s healthy and attractive?  Flossing will improve many aspects of your life and no one has mentioned the research that shows male patients who don’t floss are more likely to experience erectile dysfunction...”  

To Fill or Not to Fill: That is the Question

By Dr. Doyle Williams, Chief Dental Officer, DentaQuest

Recently, the New York Times published an article, “A Closer Look at Teeth May Mean More Fillings for Dentists,” which discussed microcavities and the different ways dental care providers treat them. A 22 year old college student who had grown up without ever having a cavity visited a dentist while at college and found out she had a cavity – in fact, multiple cavities. Somehow, in just 12 months, she went from perfect oral health to having many cavities. How can that be?

Ever new technologies make it possible for dentists to find very early stage cavities (microcavities) that can’t be seen with X-rays or the naked eye. These technologies are an effective tool in identifying early decay and allowing dentists to address it before it progresses to become a bigger and more painful problem.

The microcavities they detect are abnormalities which can be an indication of the beginnings of tooth decay. For patients who previously had perfect oral health, hearing they may have a number of cavities that need to be filled is a shock. If you are concerned that a diagnosis doesn’t match up with your prior dental history (and there has been no change in your home care or health), it is never a bad idea to get a second opinion.

Today, when dental teams catch disease in an early stage, there are more options for patients than the traditional filling. For example, dentists can watch and wait to see what happens as suggested in the article by Dr. James Bader, a research professor at the University of North Carolina School of Dentistry.

Another approach is to take preventive steps. The diagnosis of a microcavity may lead a dentist to recommend the application of sealants, a thin plastic coating applied to the teeth to protect them from the bacteria that causes dental disease and the potential for further decay.

Or, a dental health professional may attempt to help “heal” the tooth. At the DentaQuest Oral Health Center, the dental team would take steps to reduce the level of the decay-causing bacteria in the patient’s mouth, and enhance the body’s natural ability to replace minerals. So instead of placing fillings that will need to be replaced in the future, they use other measures to stop early decay, help the tooth heal, and then make it more resistant to future decay. It’s a prevention-focused approach to oral health care.

My colleague, Peter Blanchard, DDS, MBA; Director, Evidence-based Practice, DentaQuest Oral Health Center, wrote an op ed in response to the New York Times article entitled “To fill or not to fill: That is the question” which was published on DrBicuspid.com.

Finding cavities early is never a bad idea. It gives us more options to help our patients stay disease free.
