How the Pandemic Highlights Barriers to Dental Care

Posted on Wednesday, November 11, 2020

The number of Americans who have been unable to see the dentist during the pandemic has drawn attention to the importance of regular, accessible dental care. Cecile A. Feldman, dean of the Rutgers School of Dental Medicine, discusses how we can ensure that dental care is within reach for all.

How has COVID-19 affected Americans’ attitude toward oral health?

COVID has put a spotlight on the consequences of going without dental care. Not being able to see the dentist for months unless it was a dire emergency helped people realize how important it can be. Tooth infections that could have been caught early wound up abscessing. Patients who might have just needed a filling between visits required root canals. Dentists are often the first to detect oral cancer, and a lapse in appointments means some cases could have been caught sooner, improving the odds for early intervention and recovery. For people getting crowns or bridges, teeth shifted because they couldn’t see their dentist for work to be redone.

Many people have dirty teeth due to their putting off routine cleanings. Also, there is anecdotal evidence that indicates a rise in bruxism — the term for teeth grinding — because of the stress and anxiety caused by the pandemic.

Prior to the pandemic, what were some of the obstacles to accessing dental care?

For some Americans, geographical access is a problem: They don’t live close to a dentist. In many states, there are a shortage of dentists. Teledentistry, which has become widely used during the pandemic, could help partially fill that need. It could be used for preventive care: Dentists can call patients to ensure they are performing good oral health hygiene and then after checking in to reinforce the importance of oral healthcare.

For far too many patients, seeing a dentist is a financial problem. According to the American Dentistry Association, 33.6 percent of Americans lack dental coverage. Many have trouble affording care even with dental insurance, which, compared to medical insurance, often covers only a small portion of treatment costs. The situation improved with the Affordable Care Act (ACA) after it was approved in 2010. As a result, nearly 500,000 New Jerseyans had access to care that they didn’t have before due to ACA Medicaid expansions. But even under the ACA, dental care was only listed as an “essential” benefit for children.

What would make it easier for more people to get dental insurance and for that insurance to offer more coverage?

Employer health care coverage started out mostly in the 1960s as a way for industries to offer workers something without raising wages. Dentistry wasn’t a part of it because we have a bi-furcated system, where the health of a person’s mouth is somehow not regarded as part of their overall health. That needs to change. Oral health care needs to be seen as just another facet of physical health and wellbeing, and dentists and other oral health providers need to be covered the same way as others specialists, like ophthalmologists or cardiologists.

Organized dentistry initially resisted expanding Medicare and Medicaid to dental visits because they feared the government would force them to lower fees. Medicaid and Medicare still pay dentists extremely low rates compared to other providers. We don’t get paid much for screening or diagnosis. Dentists mainly get paid for actual treatment measures. In addition, there’s a big administrative burden that costs dental offices much time and energy. That must change. We also should reduce the need for documentation. Five different administrative companies are required to credential dentists where instead we could have one universal system for everyone one who has a valid license. We need to do everything we can do make sure affordable oral healthcare is available to everyone, and make the process of providing and obtaining it as easy as possible for both patients and dentists.







ADA Supports Point of Care COVID-19 Testing by Dentists

Posted on Wednesday, November 11, 2020

According to a new policy from the American Dental Association (ADA), point of care testing to screen patients for chronic diseases and other medical conditions, including COVID-19, that could complicate dental care or put the patient and dental staff at risk is within a dentist’s scope of practice. “Yet currently, rapid and reliable COVID-19 tests are not available to dentists for in-office use, which makes no sense,” states ADA President Daniel Klemmedson, D.D.S., M.D.

Dr. Klemmedson, who holds degrees in both dentistry and medicine, points out that dentists are doctors of oral health. “It is well within dentists’ scope of practice to screen not just for COVID-19 infection but also other medical conditions that may affect dental care such as glucose levels, which help screen for diabetes, and blood pressure, which help screen for hypertension. Patients with abnormal test results would be referred to a physician, other qualified medical professional or medical facility for diagnosis and follow-up care.”

“With strengthened infection prevention protocols and personal protective equipment (PPE), dental offices have re-opened safely around the country,” Dr. Klemmedson said. “Millions of patients have returned for oral health care, which is an essential health service. Dentists should be given access to FDA-authorized point-of-care testing for COVID-19 infection to add to their ability to screen patients and help to identify those infected with the virus.”

Dr. Klemmedson pointed out that dentists' areas of care include not only their patients' teeth, gums and supporting bone but also the muscles of the head, neck and jaw, the tongue, salivary glands, the nervous system of the head and neck and other areas. When appropriate, dentists perform procedures such as biopsies, and screen for chronic or infectious diseases, salivary gland function and oral cancer.

In addition, according to 2013-2016 data from the U.S. Centers for Disease Control and Prevention (CDC), 7.7 percent of people (10.2 million) reported having seen a dentist in the previous 12 months but no other medical professional.

“It makes practical sense for COVID-19 point of care testing to be included in screening procedures dentists perform,” Dr. Klemmedson said.

The U.S. Food and Drug Administration (FDA) includes dentists among those professionals who can test for COVID-19. In addition, the CDC recommends dental facilities consider implementing pre-procedure testing for COVID-19, particularly during PPE shortages.

The ADA and state dental societies are actively advocating state and federal regulatory authorities to:

publicly recognize that point-of-care testing for COVID-19 is within dentists’ existing scope of practice and

make COVID-19 tests available for use in dental practices

“With dental practices reopened across the country, dentists are already screening patients for signs and symptoms of COVID-19, and referring patients for appropriate medical follow-up when indicated,” Dr. Klemmedson said. “Unfortunately, such screening alone will not identify all individuals who are infected. Identifying infected patients is key to being able to protect both patients and dental team members from exposure to the virus.”

Given that patients receiving dental treatment may be pre-symptomatic (infected but will develop symptoms in the next 14 days) or asymptomatic (infected but will never exhibit signs or symptoms of disease), Dr. Klemmedson said it is critical to identify those individuals carrying the virus so that it is possible to minimize their contacting and potentially infecting others.

IDS 2021 – Ivoclar Vivadent Hosting Virtual Event Platform and Rheinterrassen

Posted on Thursday, November 5, 2020

Ivoclar Vivadent has developed a unique concept for connecting with all customers, dealers, and partners outside of the International Dental Show (IDS) in March 2021. Refraining from hosting a fair booth, the dental company from Liechtenstein will be offering a hybrid program that keeps everyone connected and informed.

Ivoclar Vivadent has responded to the changing circumstances with a format tailored to presenting content to the global dental industry as safely as possible. As CEO Diego Gabathuler explains, “We believe that a solely physical presence at IDS would limit our ability to connect with those who are unable to travel or have safety concerns that could limit on-site participation. A hybrid format offers convenient access to information for everyone, while minimizing risk.”

Attractive online interaction

Ivoclar Vivadent is redesigning and strengthening their touchpoints with customers, dealers, and partners to ensure responsible, exciting, and informative exchanges. “Our successful experience this year with the first ever online International Experts Symposium (IES) proved to us that new formats for our content are engaging, appealing, and in pace with global developments,” said Gabathuler. “Customer centricity is an essential pillar in the company’s strategy. We’re excited to build on our experience and learnings from the IES 2020 as we continue to innovate for our customers.” Ivoclar Vivadent has created a virtual conference and training program during IDS that will enable close interaction in a variety of formats, from one-on-one to one-to-many.

Safer networking: on-site space

Ivoclar Vivadent will also be present in Cologne in a studio at the Rheinterrassen during the IDS from March 10-13. The studio provides another contact point for Ivoclar Vivadent in a controlled environment. “The health and safety of our employees and guests is our highest priority,” says Gabathuler. “The IDS remains the leading exhibition for our industry. We want to create a conference experience for our guests in the 'new normal' that helps lead the way into the future as a strong community. At the Rheinterrassen location, we will have much more control of the situation.” He continued, “We hope to return to the exhibition halls of IDS in 2023, and I am sure that setting will reflect other innovative solutions than those we are offering in 2021.”







Koelnmesse Launches Prototype of IDS

Posted on Thursday, November 5, 2020

In order to enable trade fairs like the International Dental Show (IDS) 2021 with a physical presence and thus also exhibitors and visitors a safe trade fair experience also in times of the coronavirus, Koelnmesse in Cologne, Germany, is presenting the #B-SAFE4business Village - a prototype of a trade fair that integrates the stipulations of the Corona Protection Ordinance of the state of North Rhine-Westphalia into the event practice of international trade fairs on around 5,000 square meters of Hall 9 of the fair grounds.

A campaign that explains the extensive protective measures of Koelnmesse for the exhibitors and visitors was already launched under the title #B-SAFE4business in June. The campaign has now been enhanced by a real experience in the form of the #B-SAFE4business Village. The #B-SAFE4business Village is open for customers of Koelnmesse upon invitation up until the end of October. 

"DHM + V + C - these five letters have become part of our new everyday routine: Distance, hygiene, masks + ventilation + Corona app," Koelnmesse officials say in a press release. "Simple behavioral measures with a huge impact. Observing these rules faces trade fair organizers with huge challenges worldwide. With #B-SAFE4business Village, Koelnmesse is proving this is possible and that the trade fair organizer is well-prepared for events with several thousands of participants from all over the globe. To this end, the entire customer journey was depicted - from paperless ticketing, to the newly developed eGuard app for guiding the visitor flow, through to a wide range of stand construction concepts, which take the distance regulations into account even when space is limited. New event formats and digital technologies show how exhibitors can extend their reach using hybrid exhibition stands. Among other things, a food service and the hygiene concept of Koelnmesse are being presented for the service section. In addition to several Koelnmesse business sections, diverse service providers are also participating in the Village."

Study Indicates: Milled Prosthesis Material Performs Better Than 3D-Printed

Posted on Wednesday, November 4, 2020

In a recent study conducted by the University Hospital of Tübingen, Charité University Medicine Berlin, and the First State Medical University of Setchenow in Moscow, the milled prosthesis materials exhibit better surface properties than comparable test objects from a 3D printer or from conventional production.

The aim of the study from summer 2020 was to examine subtractive and additive samples for their mechanical polishability. Prosthesis materials obtain a smoother surface after polishing. This is particularly relevant with regard to plaque accumulation. Common prosthetic aids must meet certain qualitative criteria for a successful rehabilitation of edentulous patients, including a surface that is as smooth as possible. Abrasive wear during chewing or mechanical cleaning, poor dental hygiene and reduced salivation can lead to increased plaque accumulation and diseases. For this reason, either mechanical or chemical polishing and also coating processes are applied to reduce the microbial adhesion of the denture surface.

Three groups of materials have been produced and examined for the study: conventionally produced denture bases, which are manufactured by cold polymerization of PMMA, denture samples milled with a vhf S1 and test objects from a 3D printer. Ten samples from each group were left untreated. Another ten objects were pre-polished and ten final samples were polished to a high gloss. Afterwards the surface values of the samples were compared among other criteria.

For the fabrication of the milled prosthesis sample, one specimen was designed virtually in a CAD software and the stereolithography file (STL) was then exported to the vhf software DentalCAM. Afterwards, the file was positioned inside a circular blank made of pre-polymerized PMMA and wet milled with the vhf S1.

The result: in all three categories, the milled samples show clearly better surface characteristics than the 3D-printed and conventionally produced ones. Furthermore, the highly polished samples also show the statistically best surface values.

vhf camfacture AG is pleased about the result and the fact that the vhf S1 milling machine was used for the study. The subtractive method as a whole prevailed and proved to have superior characteristics. It has been shown that the precise vhf machine could achieve a better surface finish for more advantageous patient care. Thus, the study also proves that it is possible to achieve excellent results with an affordable and easy-to-operate dental milling machine.

The study entitled: Surface Characteristics of Milled and 3D Printed Denture Base Materials Following Polishing and Coating: An In-Vitro Study, published in the journal Materials, is available online as an open access resource.
