When an employee or patient contracts a bloodborne pathogen due to inadequate mask protection, the legal and professional consequences can be devastating for a dental practice. Are you certain your current face mask protocols meet the highest standards of care?
Dr. Sheri Doniger, DDS, brings decades of clinical experience from her practice in Lincolnwood, Illinois, where she has worked as a dental assistant, hygienist, and dentist. A past President of the American Association of Women Dentists, Dr. Doniger serves as an international speaker on infection control, practice management, and work-life balance. She has consulted for major dental benefits companies, authored "Practical Practice Solutions in Dentistry," and continues to educate dental professionals through multiple dental and dental hygiene programs. Her comprehensive background in dental practice operations and infection control makes her uniquely qualified to address the critical safety protocols every dental office must implement.
This episode provides essential guidance on face mask selection and protocols in the post-COVID era of dental practice. Dr. Doniger explains why ASTM Level 3 masks should be the standard across all dental team members, regardless of their role in the practice. The discussion covers the four critical rating factors that determine mask effectiveness, proper donning and disposal techniques, and the legal risks associated with using substandard protective equipment. This conversation offers practical solutions for ensuring consistent infection control while managing costs and maintaining team compliance.
Episode Highlights:
ASTM Level 3 masks provide 160 millimeters of mercury fluid resistance compared to 80 for Level 1 and 120 for Level 2, offering superior protection during high aerosol procedures like drilling and ultrasonic cleaning. The four key rating factors include bacterial filtration efficiency greater than 98%, particulate filtration efficiency above 98% at 0.1 microns, and optimal differential pressure for comfortable breathing throughout extended procedures.
Front desk staff and sterilization room personnel should wear Level 3 masks despite limited patient contact, as unpredictable patient presentations and potential splatter during sterilization processes create infection risks. Standardizing to one mask level across the practice simplifies inventory management, reduces training complexity, and eliminates the risk of team members accidentally selecting inadequate protection levels.
Proper mask replacement protocols require changing after each patient or every 20 minutes during aerosol procedures, with immediate replacement if masks become visibly wet or soiled. For non-aerosol procedures like examinations only, masks should be changed every hour, and contaminated masks must be disposed of as medical waste following established protocols.
Correct mask donning involves adjustable nose and chin pieces that mold over facial contours, with pleats facing downward to allow enhanced breathing volume and prevent fogging. The mask should cover from above the nose to below the chin with secure elastics that prevent gapping, and team members should never touch the outside surface to avoid cross-contamination requiring complete hand hygiene restart.
Off-brand masks present significant legal liability when labels are inaccurate or products fail to meet stated ASTM ratings, potentially exposing practices to employee lawsuits and regulatory violations. Proper documentation of mask training during employee onboarding, annual continuing education requirements, and adherence to manufacturer specifications provide essential legal protection against negligence claims.
Perfect for: Practice owners, office managers, infection control coordinators, and all dental team members responsible for implementing and maintaining PPE protocols in clinical and administrative settings.
Discover how proper mask selection and protocols can protect your practice from both infectious disease transmission and costly legal consequences.

In this society where anybody can get sued at any time, and there's a lot of employees suing
employers and employees reporting to OSHA and saying that things aren't done correctly,
I would rather put myself out of that concern and just go with a level three mask.
Welcome to the Phil Klein Dental Podcast. So the reality is not all face masks are created equal.
And understanding the risks of using subpar face masks is vital for both safety and liability.
In a dental practice where high aerosol procedures are routine, inferior masks not only put your
staff and patients at risk of exposure to harmful particles, but also open your practice to serious
legal consequences. According to our guest today, Dr. Sheri Doniger, to protect against these
risks, ASTM Level 3 face masks should be the standard of care in every dental office.
These masks provide the level of protection necessary for high aerosol procedures, such as drilling
and ultrasonic cleaning, ensuring both patient and staff safety. Dr.
Doniger will cover a myriad of issues today related to the dental face mask, including what to look
for in a quality mask, and how to train staff on proper mask practices to maintain compliance and
safety. Dr. Doniger, it's a pleasure to have you on the show. It's a pleasure to be here, Phil. I
really appreciate your inviting me. Yes. Yeah, we're very happy to have you. You certainly know a
lot about infection control. So it's no secret that since March... 2020 we are essentially
practicing in a new era of dental medicine i think all of us who work in the dental operatory are
more aware of the real dangers of aerosolized particles and body fluid in the form of splatter
blood and saliva and so forth, we know that that can carry infectious disease. And I think all of
us as healthcare professionals understand the need for an infection control strategy for the
practice, which includes quality PPE products and donning techniques, because not everybody in the
office handles the PPE and wears them properly. So there has to be some consistency there.
So in light of all this, what is different now, in your opinion, Dr. Doniger? in our dental
practices regarding PPE, specifically with face masks? In other words, what should we be doing
differently with face masks in contrast to pre-COVID with the goal of keeping ourselves and our
patients safe? Well, that's a great question. Although the official COVID pandemic has ended,
the risk of getting COVID and other seasonal influenza still exists. I can't tell you how many
patients I have coming back from vacations that are canceling appointments because they have COVID
again or a different version of it or some influenza. We're still mandated by the ADA.
the cdc and osha to follow guidelines that are standards of care that include masks gloves eye
protection protective clothing nothing has really changed on that regarding masks i am still at
level three i think everybody should still be at level three protection i think it's something that
we should uh that is a standard of care and practices was discussed um during covid and i think
it's it's continuing on into our practice lives now and for the foreseeable future.
So anybody who's participating in the dental operatory during a procedure in whatever capacity
should be wearing an ASTM level three mask. Right.
They should. Well, let me just give you a brief synopsis of why. Masks are rated with four
qualities. Fluid resistance, which is the mask's ability to prevent fluid from passing through the
material. The higher fluid resistance, the better protection. So you're looking for something about
160 millimeters of mercury. Then BFE or bacterial filtration efficiency is the mask's ability to
prevent bacteria from traveling through the material. That's measured at 0.3 microns,
and the higher BFE is better protection. So we're always looking for something greater than or
equal to 98%. The particulate filtration efficiency is the mask's ability to prevent submicron
particles from traveling through the masks. And those are measured at 0.1 microns.
And again, the higher number is better, which is greater than 98%. The delta P,
which is the differential pressure, and this is kind of an interesting number, it's the clinician's
ability to breathe while wearing the mask. And that's measured in H2O per CM.
wear and the higher number the better you're usually looking for something over five you want to be
able to breathe if you if those folds those pleats and the masks aren't expandable to your face
you're going to feel like you're suffocating all day and that's the last thing you want to do
because you want to encourage people to wear masks for protection for protecting themselves and
their patients and then you know everybody else that's in the office and you want to be able to
have this really great delta differential and the masks. I look for all these factors in deciding
how to choose a mask. And I might add, Dr. Doniger, which I find interesting, is that some of the
major companies that are making masks, like Cranberry, for instance, have eliminated the level two
ASTM mask completely from their product line. Let me explain to you what the level two masks are.
The masks are... by the light fluid barrier is considered a level one,
and that would have a fluid resistance of 80. The moderate fluid barrier has the ASTM level of two,
which is 120. And the level mass that I use is a level three.
and that's 160 millimeters of mercury and that is the best fluid resistance and that's what we
should be using because we don't want to have we just don't want the masks wet having things
passing through them so again going back to cranberry they have totally eliminated the level two
mask and are only focusing on the highest level of protection this is a really good place to start
when you're looking for a mask And you mentioned breathability, and that's a very, very important
factor in a mask. If you can't be comfortable with the amount of oxygen that you're taking in while
you have this mask on, you're going to be pulling that mask down over your chin or lifting it up on
top of your head. And that's like the worst behavior you can do when you have a mask because
obviously any pathogens... are on your skin, they're going to be transferred to the inside of the
mask. So the user, when they put the mask back on properly, are going to be breathing in those
pathogens from the inside of the mask. And that's not what we want to accomplish when we wear a
mask. So comfort, breathability, super important factors when choosing a mask.
And also I'd like to point out that the difference between a level two ASTM and a level three is
not that critical to the point where you would even have a level two. because the major difference
is in the fluid penetration and you get better resistance from fluids with a level three. And
that's measured in, as you mentioned, millimeters of mercury pressure of how much pressure is
needed to get that fluid to go through the fabric of the mask. It certainly seems to me that it
makes more sense to consolidate to a level three ASTM for the whole practice. You're getting better
protection and you're simplifying your inventory. Exactly. Prepare for, you know,
the safest dental visit that you can have. And I agree with that. And I also agree,
I kind of chuckle, you know, you go into the grocery store and you still see people wearing their
masks incorrectly, and that's not how we're supposed to do it.
of how the masks are supposed to be is right on. You want people to be comfortable wearing them.
You want them to be placed on their face, covering their nose or mouth, you know, underneath their
chin correctly. And you don't want anybody touching the outside of the mouth because that is cross
-contamination. You've already contaminated everything. Your gloves, you have to wash your hands
and start all over. You know, I've had this discussion before, Dr. Doniger, with practice owners
and they say, well, my front desk, they could use a level one. Some of the people that are just
doing sterilization. They might be using a level one or level two. What's your response to that
when an office says it's kind of overkill having level three for everybody? We never know who's
coming into the office, first of all. And when you have the front desk, somebody coming into
reception and they're coughing and everything, you just don't know. So if my team is masked,
my team is going to be masked in level three. Also, when somebody is sterilizing, there's always a
risk of splatter. So my concern would be why risk somebody in a mask that doesn't have the correct
amount of fluid protection, the highest level of fluid protection, if you are going to have any
splatter in the sterilization room. So it's also easier when you're talking about cost.
It's also easier when you're buying for the office. You don't have to buy three or four different
types of masks. So as dental practice owners, we're all faced with higher costs across the board.
I mean, everything costs more these days and it's difficult, you know, to keep your costs down. And
sometimes dental practice owners look for off-brand products and that sometimes moves into the PPE
world. So what is your recommendation, Dr. Doniger, when it comes to purchasing off-brand PPEs,
especially in the mask area? My responsibility as a practice owner is to protect both my patients
and my entire team. And we should always be really diligent to look for these great qualities in a
mask, you know, to ensure that they're ASTM rated correctly and labeled. We need to make sure that.
We are purchasing something that has quality backing behind it and testing.
When we buy anything that's off market, the labels may not be clear. As we were warned during the
pandemic, you know, always be wary of masks that have incorrect labels or words that are
misspelled. I personally look for a proven quality rather than saving a few dollars. It isn't worth
the lawsuit. So it seems to me, Dr. Doniger, face masks is not the air.
All I think about is my role is protecting my team and my patients and my community.
And I don't want to risk the protection level. I would go with a known company.
Cranberry is very well known. If it says level three, it's level three.
They used quality materials. Their masks aren't going to break. There's certain things you take
into consideration. It's just so much easier to buy something right. and good in the beginning and
use that product that the whole team is comfortable wearing and is happy with than trying to go
scramble around looking for to save a few dollars i mean that's protection is not a place where i
would say what i would look to save money it's just not i know the cranberry line has a mask called
carbon black is there anything particularly interesting about that that you want to share um i
think that the the breathing volume in there is incredible and uh i think that that's one of the
again one of the things that i look at because the last thing you want to be doing is you know
you're focused on a procedure you want to be comfortable when you're doing you know breathing and
sitting and everything else um i think that their uh their nose strap and their um chin strap you
can tightly seal around your mouth which again is in face which is again is a big factor um they
have superior fluid from from all the tests i've read they really have superior fluid resistance
and the ear loops are really soft and you know these things are around your your your ear for a
good part of an hour you want to make sure that you're wearing something that's comfortable um and
they also think one of the other things that we all you know learned during the pandemic is how the
masks some of them were fogging up our glasses and these masks do not fog they're great and even if
you're wearing them under a shield and a lot of a lot of practices are still using their shields if
you're wearing them underneath the shield you could still breathe it's it's they're comfortable and
um And there's no fogging. So what is it about the carbon black mask that precludes the fogging?
The design, the customized fit. It's just how they made it. And it was just, it was incredible how
they made them. And that was, I just very, very impressed, very impressed.
And we are using them in our operatory. So I'm very. happy that they're there. So Dr.
Doniger, talk to us briefly about the correct way of wearing a mask. And also, what is the protocol
related to changing out the mask? That's excellent question. I again, we were kind of making
comment about, you know, wearing it underneath your chin or, or, you know, above your eyebrows or
whatever, that's the wrong way. Masks need to be worn correctly. And one of the things that is the
biggest thing about masks is they should not be worn all day. The same mask should not be worn all
day. The general recommendations are to change masks after each patient or
If there's an aerosol procedure, after every 20 minutes, unless the mask is visibly wet or soiled,
just think about it. You're sitting in the chair and somebody has splatter all over their mask and
it's red. It's not the most comfortable thing to see when you're sitting in the chair. So you
definitely want to know if you have any splatter on you. Sometimes you don't see the splatter
saliva is clear, but there's still bacteria over that. If that mask gets wet, it really does need
to be replaced. Non-aerosol generating procedures, you can probably change the mask every hour.
And those are usually exams only. Mask donning, learning how to put a mask on correctly should be
part of the onboarding of new team members. People should learn how to do that. It should be gone
over every so often because people tend to forget. the infection control manager should do a review
for team members at least once a year to ensure that everybody understands mask hygiene.
And a lot of the stuff that you and I were just talking about, a mask is only as good as it fits.
It's the most important thing to consider are the adjustable nose and chin pieces to custom fit
that mask to the clinician's face. They should mold over the nose and the cheeks should be covered
and it should be molding underneath the chin. And they should maintain their shape during the time
that you're using it. They shouldn't kink. They shouldn't break. You know, it's horrible when
you've got this broken metal that's right next to your nose or underneath your chin. Individuals
with wider faces should select a mask that ensures full coverage that will cover.
the face and under the chin cranberry again is a leader in this they have masks for they have
petite masks and they have regular size masks and i happen to need a smaller mask because my face
is a little narrower it's really important to be able to get a mask that fits your face the pleats
just as a reminder to everybody should always face downward. And the folds should allow for
enhanced breathing volume. And that's what we were talking about with that differential,
with the breathing differential. It's so important to get that Delta P to have a large,
to be able to get your breathing correctly during wearing masks. The side elastics are there to
basically to reduce the fogging and the gapping around the face. You asked about the comfort of the
side elastics, and that's really important and that's how there isn't the fogging going on.
These also should be secure and not tear away from the mask.
I've had masks that we've sampled in the office that you put them on and pop. the elastic comes
popping off just as you're putting it over your ear. That's not a good thing. So again,
stick with a mask that's with a reputable company that you know is creating masks that are well.
Again, it is important to find a mask that fits your face. They should feel they aren't going away.
masks aren't going away, so they should feel comfortable when you're wearing them. Manufacturers
make a variety, as they said, of sizes, and you can make sure that they're sealed so you're
protecting yourself. You can ask your sales rep or contact the manufacturer directly to sample
masks that'll fit your face. Finally, used or contaminated masks should be cared for as any other
medical waste in the office, and following the procedures and protocols as described by the ADA,
CDC, and others. throw them away the right way and only use them once. Yeah.
So let me ask you something about the other employees. So you have a practice, your favorite
assistant got married and moved to Missouri. So they're no longer around. You hire someone new.
You start observing the way they're donning their mask, for instance, and you notice some really
bad habits. Tell me what you would do. You're the owner of the practice.
So would you get involved with getting that? person to change their habits so that,
you know, the office is running on a system of perfection when it comes to donning masks properly?
Or would you have your ICC, your infection control coordinator, do that or one of your other
employees? How do you approach that person where it's not like disparaging to that person that they
come in and they're just doing this really incorrectly? You want them to be positive about their
first week in the office, but you also want them to be safe and you don't want patients to notice
the difference in the way they're wearing their mask, maybe under their chin part of the time, in
contrast to the other employees? That's a great question. I have a small practice, so I pretty much
would have to explain this to the new employee. I would take them aside and discuss it with them.
I would... you know, just go over, take a mask out, fresh mask out, show them what it's supposed to
look like and how to discard them. I think it's in a larger practice,
an infection control person or whoever's in charge of team training would be the person that would
be reviewing how the new employee would be. not only donning a mask,
but donning their gloves and their lab coats and all the other personal protective equipment that
they'd be using. But it's kind of, there's so many infographics out there that you can show people
how to wear their masks and how to be safe. And I would have a conversation again,
you know. bringing it back to safety. This is to protect you. We want you working here a long time,
and we want to make sure that you are as safe in this practice as possible. Now,
you need a certain amount of training every year, right, for OSHA guidelines, and you also need
documentation in the office. Correct. Yeah, so what you just said, is that something that should be
documented so that when someone's onboarded? They look at this documentation as part of their
training and sign off on it so that you have legal documentation.
You have something to show an attorney, God forbid, you're sued or something,
that all of this stuff was handled in the best possible way and it wasn't ignored. It's not
negligence if somebody... something wrong that could lead to the transmission of a blood-borne
pathogen from one employee to another or, God forbid, a patient to an employee or vice versa. Where
is this documented or is it? There are employee manuals. There's also OSHA training that...
have to go through yearly, minor yearly. And we also have and they do have to sign off.
And we also have state mandates are different. I, you know, I can only speak to Illinois,
but California might be different. There might be different ongoing things that they have to take.
There has to be continuing education offered. I think that. I again,
I think that it's it's definitely part of the onboarding thing. You can't expect to hire somebody
and they know how to not only mix every single every single bonding agent that you have and and put
a mask on and do everything the correct way because nobody knows how they were trained in their
last practice. So every new employee that comes in, you have to treat them like this is their first
job and that they should they should learn. the right way. So I know you're not a lawyer,
Dr. Doniger, but what is the legal risk involved with a scenario where a practice buys an off
-brand mask and it claims to be a level three, but obviously when, let's say,
something happens and the masks are tested and they're inferior, they don't match up to the claims
that were made on the box or what was made on the website where it was being sold, or The scenario
where there's random masks around the office and the dental team member meant to pick up a level
three mask, but because there were level one and level two masks in the practice, they picked up a
level two mask and they went into an operatory where there was a very heavy aerosol and the level
two mask did not have the protection against fluid penetration. And God forbid there was a
transmission of a illness from the patient to the employee. It seems to me there would be quite a
lot of liability. on the practice if something like that happened. So if you can,
just briefly address that. In this society where anybody can get sued at any time, and there's a
lot of employees suing employers and employees reporting to OSHA and saying that things aren't done
correctly, I would rather put myself out of that concern. and just go with a level three mask,
the highest level of protection, have absolutely the best training and make sure that everybody is
protected the same way I'd be protected. You know, as a practice owner and the lead doctor,
my job, as I said, is to protect not only my patients, my team, but myself and my family. As a
mother and a grandmother, I want to ensure that I'm using the highest standards of masks to keep us
all protected and avoid any kind of loss. Yeah, and that's a good point that you made that there's
actually concern about employees suing employers and reporting them for reasons of being terminated
or any reason actually. They feel that they were mistreated in some manner.
They didn't get the vacation time they thought they would get and then they just send in a report
and then you're vulnerable. So an office certainly doesn't want to be in that situation. So Dr.
Doniger, it's been very helpful and we're really happy to have you on the show. Any closing points
that you would like to make for our audience? So just to clarify, there are several companies that
make great masks and Cranberry is one of them. They're just the ones we choose for our practice.
You certainly have the ability to choose whatever. you would like to use in your practice.
But find something that you're comfortable using and that your team likes using and stick with a
level three. Thank you very much, Dr. Doniger. We appreciate your time. Thank you so much. Thank
you, Phil. It was an honor. Appreciate you asking me.
