We’ve skipped lots of dental care during COVID-19. Now hygienists are having a wild time

We’ve skipped lots of dental care during COVID-19. Now hygienists are having a wild time

Dental hygienist Jeannette Diaz’s patients sometimes cry. Lately, she’s been crying with them.

It’s not just because so many people refrained from getting dental work during much of the COVID-19 pandemic, leaving her to scrape off more than a year’s worth of tartar and plaque. It’s not just because the labor of cleaning teeth can take a toll on hygienists’ bodies.

It’s also because the patients are unburdening themselves on her — describing the tragedies and heartaches that have bombarded them during the pandemic. Many tell her how the coronavirus took their loved ones.

Dental hygienists “work in such close proximity and cover so many aspects of [a patient’s] life in going over their medical history that grief and loss and depression come up as a topic of conversation,” Diaz said.

The start of the pandemic brought dentistry nationwide to a near standstill. Now, with COVID-19 vaccines readily available and new coronavirus cases down significantly in the U.S., patients are clamoring for teeth cleanings.

June 28, 2021

In April 2020, overall patient volume at private dental practices nationwide plummeted to 7% of the pre-pandemic baseline, said Marko Vujicic, who oversees American Dental Assn.’s policy research activities. As of this month, volume is back up to 88%, Vujicic said.

Diaz, who has her own practice and travels to patients’ homes across Los Angeles and Orange counties, has been seeing that resurgence. She said that each weekend, she sees about six patients and has to reject about four additional people who call her wanting appointments.

Before the pandemic, Diaz said, she would see patients for about an hour each, but now her visits can last twice as long. That’s because of the condition of the teeth and because patients often grab the chance to talk to her about their troubles.

“It can be emotionally exhausting and draining when you hear about what they are experiencing mentally and emotionally that leads them to … be unable to care for their oral hygiene,” she said.

Diaz said she sympathizes with patients who were scared to seek dental care when the coronavirus was running rampant in California. But when looking into a neglected mouth, she becomes sad.

“I wish I would have been able to see them sooner,” she said.

Similar concerns weigh on Raiza Parada, a hygienist at a dental clinic in Long Beach.

“Just knowing that my patient’s health is on the line … and I couldn’t really do anything about it” while the patient postponed appointments. “That’s kind of emotionally hard on me,” she said.

A hiatus in oral care can have lasting consequences.

Patients “could be seeing … gum disease, bleeding gums — which potentially can lead to tooth loss,” said P.J. Attebery, a clinic coordinator with the Los Angeles County Comprehensive Health Center.

Germs left to multiply in the mouth can also spread and cause trouble in other parts of the body. According to the Mayo Clinic, endocarditis, cardiovascular disease, pneumonia, and pregnancy, and birth complications can be linked to oral health.

Cleaning those neglected mouths takes a heavier physical toll on hygienists too.

“The longer that the tartar … stays on the tooth surface, the more difficult it is to remove,” Parada said. “We have to strive to maintain good ergonomics and posture to prevent injury to our bodies, all while trying to clean teeth using sharp metal instruments in a very slippery environment while making the whole experience comfortable for patients.”

She said she’s been experiencing more pain in her neck, shoulders, upper back, and forearms. Cleaning the back teeth tends to be the hardest on her because that’s the area patients neglect most, she said.

Parada has offset some of the effects by doing strength training, getting massages, taking Epsom salt baths, and using a foam roller to loosen the muscles in her shoulders and upper back. But it’s not magic.

“I’ve never had pain like this in my whole career. I’ve been a licensed hygienist since 2012,” she said.

Wearing layers of personal protective equipment, along with the pressure to do more cleaning during a regular-length appointment, also taxes Parada. “Wearing the gown makes me hot and sweat more than I used to, and I feel dehydrated,” she said.

Diaz worked in difficult conditions even before the pandemic: She said the equipment she carries into and out of each patient’s house weighs 43 pounds, and that doesn’t include an ergonomic patient chair.

“I end up seeing [patients] in their bed, on their couch, on the recliner,” she said. “I have to bend and twist into weird positions.”

When a patient has a heavy buildup of tartar, Diaz has to apply extra pressure, exacerbating the strain on her own body.

Dental care has been the most neglected healthcare service during the pandemic, according to an American Dental Assn. survey of U.S. households conducted in May.

But if you have a long history of lackadaisical oral hygiene at home, your hygienist won’t necessarily believe the pandemic is behind your current tartar situation.

“I’m used to … people making excuses for not being able to floss, but it’s interesting how [now] people would tie their excuses to the pandemic,” Parada said. “The narrative changed.”

It doesn’t really matter why your teeth are the way they are, Parada said: Just show up.

“It’s very important for patients to know that it is safe to come back to the dental office to get their teeth cleaned,” she said.

Odds of Catching COVID at Dentist’s Office Very Low: Study

Odds of Catching COVID at Dentist’s Office Very Low: Study

Do you need to have your teeth cleaned or a cavity filled?

Go ahead.

Dental treatment won’t put you at risk for contracting COVID-19, a new study affirms.

“Getting your teeth cleaned does not increase your risk for COVID-19 infection any more than drinking a glass of water from the dentist’s office does,” said lead author Purnima Kumar, a professor of periodontology at Ohio State University in Columbus.

Because COVID-19 spreads mostly by airborne droplets, fears have persisted throughout the pandemic that saliva released during a dental procedure could spread the virus.

For the study, Kumar’s team analyzed the genetic makeup of organisms found in air samples during a range of dental procedures.

The takeaway: Water solution from irrigation tools — not saliva — was the main source of any bacteria or viruses in the spatter and spurts from patients’ mouths.

Even when low levels of the SARS-CoV-2 virus were found in the saliva of asymptomatic patients, the aerosols generated during their dental work showed no signs of the coronavirus, the research found.

“These findings should help us open up our practices, make ourselves feel safe about our environment and, for patients, get their oral and dental problems treated — there is so much evidence emerging that if you have poor oral health, you are more susceptible to COVID,” Kumar said in a university news release.

“Hopefully this will set their mind at rest because when you do procedures, it is the water from the ultrasonic equipment that’s causing bacteria to be there. It’s not saliva. So the risk of spreading infection is not high,” Kumar said. “However, we should not lose sight of the fact that this virus spreads through aerosol, and speaking, coughing or sneezing in the dental office can still carry a high risk of disease transmission.”

The findings were published May 12 in the Journal of Dental Research.

Dentists can increase patients’ confidence about the COVID-19 vaccines

Dentists can increase patients’ confidence about the COVID-19 vaccines

A patient discussion guide, posters added to CDA’s COVID-19 Vaccine Information Toolkit

Quick Summary:

CDA added nine resources to the COVID-19 Vaccine Information Toolkit to promote vaccine education and awareness in the dental office and facilitate dentists’ conversations with patients. The resources include a discussion guide, patient email template, posters in English and Spanish, and more.

All Californians ages 16 and older became eligible to receive FDA-approved COVID-19 vaccinations beginning April 15. As of April 19, one in four Californians was fully vaccinated against COVID-19, but vaccination rates vary greatly by county, and public health experts agree: Achieving Achieving broad inoculation against the coronavirus is essential to preventing additional virus variants from emerging and causing breakthrough infections, hospitalizations and deaths. Wider inoculation is also central to a safe reopening of California’s economy.

Limited vaccine supply and too few vaccination sites account for some disparate vaccination rates across the state, but vaccine hesitancy, defined by the World Health Organization as “delayed acceptance or refusal of vaccines despite availability of vaccine services,” remains a significant concern and contributor to California’s low vaccination rate overall. A statewide survey (see page 17) conducted in March by the Public Policy Institute of California found that 14% of surveyed adults in the state would “definitely not get the vaccine.”

Dentists can boost patients’ confidence in the vaccine, influence vaccination decision-making 

The public is more likely to trust the information they receive about the COVID-19 vaccine when that information comes from public health entities or health care professionals. In fact, a recommendation from a health care provider is one of the strongest determinants of vaccine acceptance, recent research shows.

As trusted health professionals, dentists are positioned daily to discuss COVID-19 vaccination with their patients and the public, instill confidence about the COVID-19 vaccine, and ultimately influence their patients’ decision-making about the vaccine.

Dentists can, for example, include a question about COVID-19 vaccination on the patient intake form, which will provide an opportunity to address vaccination with the patient during their visit. The dentist might start the conversation with “I can see from today’s intake form that you have not received your COVID-19 vaccine.” According to the CDA resource Instilling Vaccine Confidence, such announcements demonstrate the health care provider’s confidence in the vaccine and establish vaccination as the norm.

The new CDA resource also provides specific communication strategies dentists can adopt in the office to promote vaccine acceptance among their patients, such as showing empathy and providing facts to counter vaccine misinformation.

New resources in COVID-19 Vaccine Information Toolkit assist dentists’ conversations 

CDA added nine resources to the COVID-19 Vaccine Information Toolkit to promote vaccine education and awareness in the dental office and facilitate dentists’ conversations with patients. The toolkit, initially released in January, is intended to help dentists and their teams understand current information about the COVID-19 vaccine and vaccine distribution and administration. It also provides best practices and resources for dentist employers.

The newest resources are:

CDA partnered with HealthNet to produce the vaccine discussion guide Proven Strategies Help Shorten Talks About the COVID-19 Vaccines. The guide provides evidence-based strategies for talking to patients based on their level of vaccine acceptance or hesitancy.

Access all the new resources and dozens more in the CDA COVID-19 Vaccine Information Toolkit.

Reducing Aerosols and Splatter for Safer Dentistry with Solea®

Reducing Aerosols and Splatter for Safer Dentistry with Solea®

UP TO 99.9% REDUCTION IN AEROSOLS & SPLATTER

Due to the recent COVID-19 pandemic, dentists are understandably concerned with the risk of disease transmission from patient to practitioner and staff. There is evidence that aerosol generated during dental procedures may harbor active pathogens that can infect the dentist or hygienist. Small, invisible particles may contain these pathogens to a small extent, but larger droplets and splatter are likely to contain significant concentrations of these active pathogens and are less easily removed by nearby suction.

To investigate how Solea® can help dental practices reduce the risk of transmission, the Convergent Dental R&D team designed two structured and controlled studies: a macroscopic and a microscopic. Study results demonstrate that Solea supports safer dentistry by reducing aerosols and splatter by up to 99.9% compared to the traditional drill.

Solea vs. the Drill: General Device Settings

The studies described below were performed by a dentist in a dental clinic using a conventional high-speed drill and the Solea all-tissue laser. Each study also used an HVE suction device during each procedure.

THE DRILL

High-speed drills rotate at speeds up to 400,000 rpm, use air pressures in the range of 30-40 psi, and utilize water flows in the range of 30-60 ml/min. The high-speed drill used in this study rotated at 350,000 rpm, used 30 psi air pressure, and used a 50 ml/min water flow rate. These settings followed manufacturer approved guidelines and were deemed acceptable by the dentist.

SOLEA

Solea has a range of settings that can be adjusted by the practitioner. For this study, the following manufacturer approved guidelines were used: 10 PSI, 8 ml/min water flow, 50% cutting speed and 1.25mm spot size. These settings were deemed acceptable by the dentist.

Macroscopic Testing: Splatter Spread and Visualization

The objective of the macroscopic approach was to obtain a visualization of the splatter and droplet spread generated during a hard-tissue dental procedure. To mimic this, extracted human molars were placed in a model of a human head, and mounted in normal positions inside the mouth. To clearly view the splatter created, food dye was added to the water reservoirs in both Solea’s and the chair’s system. The high-speed drill and laser were each operated for ~10 seconds.

The drill generated splatter as far as 45cm while Solea only produced minimal detectable splatter a few millimeters from the mouth (Figure 1). The study confirmed that Solea produces, at a minimum, 97% less splatter than the drill.

Microscopic Testing: Quantification of Splatter Concentration

The aim of this study was to quantify splatter and aerosol residue created directly outside of the oral cavity. Extracted human molars were again placed in a model of a human head and food dye was added to the water reservoirs in both Solea’s and the chair’s system. Glass slides were placed at various distances from the tooth, and both the drill and laser were used to cut following the clinical settings previously described. The slides were then examined under a microscope to compare splatter coverage (Figure 2).

A computer program (ImageJ) was used to quantify and compare the total coverage area of the residue.

The study results show that Solea produces ~98% less splatter at 2mm from the tooth, and ~99.9% less splatter at 8mm (Figure 3). Compared to the drill, Solea produces exponentially less splatter as you measure farther from the tooth.

Conclusion

These structured and controlled studies corroborate that Solea supports safer dentistry by reducing dental splatter and aerosols by up to 99.9% compared to traditional handpieces. Solea achieves this by utilizing ~67-83% less water flow, ~74% less air pressure, and by cutting without contact, as opposed to drills, which cut using burs that spin at up to 400,000 RPM.

These findings support recent guidance provided by the ADA, recommending dentists use clinical techniques that “reduce aerosol production as much as possible, as the transmission of COVID-19 seems to occur via droplets and aerosols.”
