AI in Dentistry Part 2: What can we learn from healthcare?

Building from our previous blog post, Artificial Intelligence in Dentistry,  where we discussed the current applications of AI in dentistry, we are going to have a look at the medical world where the use of AI is more developed, to see what is out there and how it can apply to dentistry today. In our last post, our CTO explained a particular subset of AI, known as Natural Language Processing (NLP), which you can read more about here in case you missed it. 

Applications of AI in Healthcare - some important distinctions

Before diving in, there are some important distinctions to be made around AI and how it is used. As we touched on in the previous blog, AI is a technology. It is a malleable tool that can be applied in very different ways to deliver different solutions. So it is important to keep separate the technology - what is under the hood, and then the solution - what problem is the technology helping to solve. 

The solution is the most important part to focus on when looking at any piece of technology. For example in Dentistry, the same AI technology might be applied in practices to automate patients' follow up care reminders based on their treatment. The solution here is improved patient outcomes and more streamlined follow up visits, but the same technology can be applied to read medical history and then personalise consent accordingly, increasing clinical safety and improving patient experience. This is the same technology being utilised in different ways to solve contrasting problems.

In healthcare, there is the added dimension of the application of different technologies, too. These largely revolve around care settings. There are 4 key care settings: Acute/Hospital, Primary/GP, Community & Mental Health, Social Care & Long Term Care (this can be in patient’s own homes, in residential homes or in a number of other places such as day centres or supported housing). This is important as any technology that is applied in a different care setting can lead to very different solutions.

How is AI being used in Healthcare?

Let us now turn to examine some of the different applications of AI in healthcare and some of the problems they solve. While there are many applications of AI in healthcare, three that have become prevalent in the last few years are diagnostics, triage and self-care (Spatharou, Angela, et al. 2020).

Diagnostics & Triage

The biggest application area of AI in diagnostics is in diagnostic imaging. This means that instead of a clinician needing to check through every image they record for abnormalities, whether it be in radiology, oncology or cardiology, AI technology can analyse these images in the background and identify “normal” and “non-normal” scans very quickly, with a high degree of sensitivity and specificity. This has led to dramatic effects on the workflow of clinicians, by primarily reducing the workload volume and allowing for patients to be prioritised, too. is an example of a UK company that does this. They analyse X-ray images of the chest and lungs and can provide heatmaps of problematic areas and diagnoses. They have seen growth both in the UK and globally, and are being used to help diagnose and triage COVID patients, highlighting how diagnostic tools are closely related to triaging solutions too. 

AI can also be used to diagnose and triage patients before care is delivered. Products known as “symptom checkers” have seen large growth, especially throughout COVID - the biggest names in this space are Babylon Health and Ada. Both companies use AI to analyse a patient's symptoms and characteristics and provide a health diagnosis and then direct them to the best care pathway.  Effective use of this tool by primary care clinics means that less patients will be booking appointments, as many cases can be diagnosed and self treated, reducing their workload. 

Self care

Self care is a growing area of digital health, as it is another means to treat patients outside the practice. Where the application of AI in this area becomes powerful, is when it is combined with remote patient monitoring - being able to track the various different conditions of patients when they are outside the clinic using a wearable device, for example heart rate, blood pressure and more. 

Taking the example of Current Health, a self care platform that uses wearables, the AI in their platform enables changing conditions to be analysed. If a patient shows signs of deteriorating health, the clinician can be alerted before the condition becomes more severe or leads to complications. 

What can we expect to change in dentistry?

One of the key takeaways from healthcare is that AI is an extremely flexible tool that has been applied in various care settings to deliver on a wide range of solutions - be it clinician workflow, patient outcomes, early diagnosis and prevention, and more. Nothing is off limits in terms of what the technology may be able to solve - it is simply a case of identifying the problem and finding the right application to use AI to solve it. 

As was mentioned in Part 1, Flynotes is already using a strand of AI - Natural Language Processing (NLP) - to reduce the time needed to deliver, and the quality of, informed consent. While many can speculate on how some technology will be applied in dentistry, there is much to be learnt from the healthcare market when it comes to use of AI technologies. It is only a matter of time before we see the rise of various different applications of AI throughout dental practices to solve a wide range of problems.
