In 2017 the American Dental Association adopted a policy encouraging dentists to screen patients for sleep-related breathing disorders (SRBD). This includes assessing a patient’s risk for SRBD as part of a comprehensive medical and dental history and referring affected patients to a physician as appropriate. When this happened, I called my friend Dr. Steve Carstensen, who is at the forefront of sleep dentistry and asked him what we should implement in our dental practice. One of the tools he suggested is a quick and easy visual assessment called a Mallampati score.

The Mallampati score is one of four things we now do in my practice as a four-part sleep screening. (In Dr. Kelly Brummet’s recent PankeyGram article, she wrote about what this score determines and how she uses it in her practice, so you will want to go back and read that article as well this one.)

We have laminated copies of the Mallampati visualization chart (see below), which we printed from the Internet. We used these for visual reference in both of my operatories and the hygienist’s operatory. To make a visual assessment of the back of the patient’s mouth, say to the patient, “Open wide.” You don’t depress the tongue. The patient doesn’t say “aah.” The patient just opens wide. Then you look to see which of the four Mallampati images most closely matches what you see and give the patient a 1 through 4 score based on the image.

This is just a simple way to see if we think anatomically the patient can move air past the base of the tongue. My hygienist and I do this in conjunction with the STOP BANG questionnaire, Epworth Sleepiness Scale and asking about nose breathing.

Screening our patients for airway and breathing issues is becoming a standard in dentistry. One of the things we have started to do every day in our Hygiene rooms, with our patients from three years old to very elderly, is visually looking at the back of their mouth and assign a Mallampati score.

The Mallampati score was developed by anaesthesiologist Seshagiri Mallampati, in 1985, as a non-invasive way to assess the ease of endotracheal intubation. The test is simply a visual assessment of the distance between the base of the tongue and the roof of the mouth.

In our practice, we begin a conversation about airway with patients. The Mallampati diagram (see below) allows both us and our patient to visualize, on a score of 1 to 4, the patient’s anatomical airway. We laminated the Mallampati diagram off of Google Images, and we can give it to the patient to hold while we screen them, or we share it with them after screening to let them see why they received the score they did. We then continue the conversation with them about their airway and why it might be a good idea for them to observe sleep patterns or be referred to a sleep physician for further diagnosis.

We are bombarded weekly with ads for this or that course in “airway management” or “how to make money treating sleep apnea.” And, we are dealing with airway management every day whether we like it or not.  

Who has not had a patient come in with a worn dentition who claims, “Doc, I can’t ever remember grinding my teeth.” How about the patient who keeps fracturing restorations and says the same thing? You might want to question these folks or their partners about sleep habits. It is very likely you will find they are members of the population with some form of sleep-disordered breathing.  

Do you remember why we learned to fabricate and adjust bite splints?  

Have you had parents ask you about what it means when they can hear their young child grinding his or her teeth at night? Childhood bruxing is almost always a symptom of some sort of airway issue. What is happening in a child who presents with proclined incisors and an anterior tongue position? Do you think putting the child in headgear is going to solve the underlying reason the tongue has to be forward so they can breathe? 

We don’t have to treat all these issues, but we certainly should be able to communicate with our specialists and medical community for appropriate diagnosis and treatment of underlying issues that have a direct impact on the success or failure of our restorative care. 

The American Sleep Apnea Association estimates that 22 million Americans suffer from sleep apnea. Since we see our patient base, on average, two times a year, it makes sense that we should be doing at least a basic screening for sleep-disordered breathing. This can be anything from mild snoring to serious sleep apnea.  

Basic diagnostics would include paying attention to a person’s body mass index, neck size, asking whether they snore, and providing the Epworth sleepiness scale as part of your standard health history. Be aware that some folks with the worst sleep apnea or narcolepsy are not overweight. These are often the very fit appearing folks who are serious bruxers. 

If you really want to get involved in treating these people, you need to get more education.

Either at The Pankey Institute or somewhere that has a multi–day course. You need to commit to going into the process deeply, as there is much to learn and treatment is not simple. You will quickly learn that unless you develop great systems and team members, it is not an easy way to make money. However, you will be truly saving lives. 

If that does not sound right for you, commit to being a good diagnostician and develop an excellent referral network with some ENT doctors in your area. Most of these doctors are looking desperately for a dental colleague with whom they can discuss cases and develop treatments beyond just the use of CPAP. If you can refer just one child for early treatment each year and help prevent a heart attack or stroke for a person with undiagnosed sleep apnea, you will have done great service whether you get involved in active treatment or not.
