Many people use braces as a way of straightening their teeth and to improve their oral health. However, braces do not always fit, and can become loose easily – which inhibits their impact. But new research has shown that artificial intelligence can assist with straightening teeth, and provide much more accurate fittings for aligners. This research can help many people.

Anyone that has had braces in the past will know about the difficulties of them being placed correctly and comfortably. Moreover, they are often either too loose or too tight.

However, this could soon be a thing of the past. Researchers have developed a new tool which – with assistance from Artificial Intelligence (AI) – can predict how teeth will move to ensure that braces fit well and are comfortable [1].

This is very positive news, and could result in far more comfort for many with braces. It is also an example of AI’s growing influence on dental research.

Background

This research looked at braces. Braces are tools that help to straighten teeth. They are extremely effective, helping to enhance a person’s appearance, prevent tooth decay and dental injuries, and protect teeth from misaligning.

Braces are very common. For example, in the United States, around 4.5 million people wear braces at any one time [2]. It isn’t just children either that wear them, over 1 million adults wear them in the United States too.

Even though braces are incredibly common, it can be very challenging for orthodontists to fit them in a way that will result in comfort for their patients. Even when they do fit initially, teeth continue to shift slightly throughout a person’s life.

For those whose braces do not fit correctly, it can inhibit the aligning process and cause discomfort in eating and general mouth movement. Therefore, any way of improving the fitting process of aligners can be helpful.

The Research

The research was conducted by a team from the University of Copenhagen and technology company 3Shape. Their research has been published in the IEEE Access journal [1].

The team aimed to create a tool that could simulate how braces should fit on a patient to predict the exact shape that can best-straighten a patient’s teeth [1].

The research took place in Denmark, where around 30% of Danish youth up to the age of 15 wear braces [1].

A crucial part of the research process was to use scanned imagery of teeth and bone structures from human jaws. Then, AI used these to predict how braces should be designed.

The research also involved a process where the researchers mapped sets of human teeth using detailed CT scans of teeth and the periodontal ligaments – which are a connective tissues that holds teeth in the jaw [1].

This creates a precise digital imitation of the human jaw. This type of imitation is known as a “digital twin”, with the researchers building up a large database of “digital dental patients” [1]. The idea of the “digital patient” is relatively new in healthcare, but can certainly help with oral health.

So how will this work in practice? The computer model is capable of creating accurate 3D simulations of a patient’s jaw, which can be taken ahead of the alignment process.

Then, when the orthodontist is preparing the aligners, they can use the 3D simulation to match up aligners that should fit well. This should reduce the need for trial and error and repeated visits.

The simulation produced incredibly accurate results. Therefore, they can be applied to individual patients, with the 3D simulations capable of producing strong imitations of each patient’s teeth.

Author Comments

The researchers were pleased with the outcome of the research. Moreover, this research is also another example of how AI is impacting dentistry in a positive way.

Professor Kenny Erbelen of the University of Copenhagen, was one of the authors. Erbelen commented on the findings, stating that the “simulation is able to let an orthodontist know where braces should and shouldn’t exert pressure to straighten teeth” – thereby aiding the fitting process [3].

Furthermore, Erbelen pointed out that the current process involves “a great deal of trial and error”, but that the simulation can help to “reduce [this process] in the long run” [3].

Returning to the discussion surrounding the “digital dental patients”, the authors also pointed out that this could be extended to use for physical health. For example, the researchers argued this could be used for hip implants. This is an exciting additional development.

The researchers did caution that the tool would need to clear some regulatory hurdles before being offered by orthodontists. But they believe this is a strong possibility in the near future.

Overall, these findings are positive, and should result in improved treatment outcomes for patients going forward. Having more comfort with aligners is important, with this tool likely to help with this.

Tooth sensitivity is a very common problem that causes issues for many people. In an effort to combat this problem, a team of researchers have developed a new dental lozenge, which aims to provide a permanent fix for tooth sensitivity. Their research involves a peptide-based solution, which could have a very positive impact on oral health. This research has the potential to help many people around the world.

If you were to ask a group of people what the most annoying part of eating or drinking is, it is almost certain that at least one person would mention tooth sensitivity.

Tooth sensitivity involves a tooth, or teeth, to become sensitive – typically to cold or hot food or drink. This causes discomfort and is normally a sign of a dental problem.

However, new research has helped to develop a dental lozenge that has the potential to lessen or even eliminate tooth sensitivity [1]. This discovery could transform the approach towards treating tooth sensitivity entirely.

What is tooth sensitivity?

Tooth sensitivity is a common issue that involves a painful sensation when a person drinks or eats something hot or cold. It doesn’t necessarily need to be anything unhealthy – with even a cold glass of water being capable of triggering the pain.

This painful sensation develops overtime, with acids (caused by sugar and bacteria) wearing away at tooth enamel. Therefore, this causes a process of demineralization, which leaves the tooth’s hard exterior defenceless, exposing the roots and nerves.

Research shows that tooth sensitivity affects at least 12% of American adults [2]. The same research found that tooth sensitivity affects those aged 18 to 44 the most [2].

Tooth sensitivity: The problem

Dentist Sami Dogan is a Professor of Restorative Dentistry at the University of Washington and served as one of the authors of the research [3].

When introducing the issue, Dogan has said that in 30 years of practice, problems like cavities and dental implants have become routine. However, the main problem his patients have is teeth sensitivity [3].

Dogan says “we see patients with hypersensitive teeth, but we can’t really help them” [3]. He has pointed out that most existing treatments focus on treating the symptoms, rather than “addressing the root cause” [3]. Therefore, existing treatments do not provide a solution, instead a temporary fix is provided at best.

The Research

Because of this problem, Dogan and a team of researchers sought to find a treatment that could address the root cause of tooth sensitivity. Their findings were published in the ACS Biomaterials Science & Engineering Journal [1].

As mentioned above, tooth sensitivity is linked to the process of demineralization. With this in mind, the researchers sought to reverse this loss, with the belief that this could be a permanent fix for this issue. To do this, they designed their solution to be molecularly biomimetic – which made it resemble the molecular process which develops teeth [1].

The protein amelogenin is key in the natural development of human teeth [1]. The researchers used peptide, which is a derivative of emelogenin. Peptide is a short chain of amino acids [1].

The researchers tailored the peptide for it to latch onto calcium and phosphate ions, which are the main components of tooth mineral. Therefore, this combination can help to build new mineral microlayers on teeth.

Then, the researchers found that when new mineral microlayers were applied to the teeth, that this protected the tooth nerves. Therefore, this can result in tooth sensitivity either disappearing entirely or significantly lessening [1].

The research was able to produce a solution that built new mineral microlayers that are capable of penetrating deep into the tooth. Therefore, this helps to create an effective and long-lasting natural protection [1].

While having this solution is excellent, the next question concerns how it could be administered. The researchers suggested that the solution could be integrated into almost any type of product!

For example, this may include a dental lozenge – which would be their preferred approach. For upcoming trials, they aim to use lozenges at first [1].

Furthermore, the researchers also suggested that formulations like toothpaste, mouthwash, dental gels and even tooth whitening products could have the solution integrated within them [1].

What this means

These findings are very positive and exciting, especially given how many people suffer from tooth sensitivity. It is something that can put people off drinking or eating.

The researchers have high hopes for the future. They want to provide easily accessible relief for everyone worldwide that suffers from tooth sensitivity [1].

Lead author Deniz T. Yucesoy commented on the findings. Yucesoy said that the research created technology that “forms the same minerals found in the tooth, including enamel, cementum and dentin alike, which had dissolved previously through demineralization and caused sensitivity” [3].

Explaining how the sensitivity stops, Yucesoy said that “the newly formed mineral microlayers close the communication channels with the tooth nerves”, which means sensitivity “shouldn’t be an issue” due to the technology [3].

This research is certainly very promising and should have a very positive impact on the oral health of patients around the world. Hopefully the solution will fulfil its potential!

Thinking points…

1) As mentioned above, tooth sensitivity very common. Do you have sensitive teeth? If so, don’t suffer in silence, as help is available! Make sure that you mention your tooth sensitivity at your next dental appointment so that your dentist can take a look to see if there is a problem that can be fixed. We recommend booking an appointment as soon as possible!

2) We’ve spoken above about how there is help available for sensitive teeth. However, we need to remember that the focus should always be on prevention! One of the most effective ways of avoiding sensitive teeth is cleaning your teeth regularly and flossing. Another crucial thing to do is to attend regular dental check-ups, as this provides a dentist with a chance to take a comprehensive look at your oral health and suggest treatments if needed. Remember to book an appointment soon!

A recent labour board ruling has found that the Treasury Board acted in bad faith by delaying negotiations with the Public Service Alliance of Canada in regards to the new dental care plan. This has led to accusations that the progress of this plan has been stalled intentionally. However, the Federal Government have now announced that it is appealing the ruling.

The Federal Government has announced that it is appealing a recent labour board ruling that found the Treasury Board acted in bad faith due to recent indiscretions with the Public Service Alliance of Canada (PSAC).

The finding was that the Treasury Board acted in bad faith by delaying negotiations regarding a new dental care plan with PSAC [1]. This allegation has resulted in debate and discussion regarding the situation.

The Ruling

In June 2022, PSAC filed a complaint against the Treasury Board [1]. This complaint came almost six months after the union approached the government to begin negotiations about the dental plan.

At the end of March, the Federal Public Sector Labour Relations and Employment Board made a ruling that found that the Treasury Board had violated a section of the Federal Public Sector Labour Relations Act [1].

The ruling stated that the Treasury Board had violated the aforementioned act by not agreeing to start negotiations for the renewal of the national dental plan while it pursued a benchmarking study on the topic at the time [1].

The implication is that the Treasury Board didn’t act fairly through their actions. However, this version of events is being challenged by the federal government.

Government’s appeal

The government have lodged an appeal against the ruling with the Federal Court of Appeal [1]. In their application, the government has stated that the Treasury Board invited PSAC to partake in the dental plan study on multiple occasions last May.

The Treasury Board has since said that the government has completed the benchmarking study – which is a contentious topic that has caused some problems.

Moreover, they state that the union declined this and instead filed a complaint that the government was failing to bargain in good faith with them [1]. Clearly, the government have a different set of events.

Continuing, the application of the government stated that the labour board rendered an “unreasonable decision” through its finding that “there was a breach of the duty to bargain in good faith” [1]. Moreover, the government also argued that it was unreasonable for the labour board to believe it was their jurisdiction to hear such a complaint.

PSAC’s response

PSAC have since said that its goal from the beginning was to get the Treasury Board to negotiate an update to the dental plan. Given that it represents almost 200,000 federal public service workers, this is understandable. Furthermore, they claim that the government has intentionally stalled this process [1].

PSAC has said that they contacted the government in an effort to arrange talks on the subject, but has not heard back [1]. The two sides seem to be at an impasse.

Impact on the dental care plan

Martin Potvin is the spokesperson for the Treasury Board. He commented on the situation, stating that the board “are committed to working towards a modernized Public Service Dental Care Plan that is science and evidence-based and supports employee wellness in a manner that is fair for employees and for all Canadians [1].

It does appear to have slowed down the progress of the dental plan. David Orfald of the labour board suggested that “because the parties have not been able to commence negotiations, they have not been able to engage in the rational dialogue they need to complete the renewal of the plan” [1].

What will happen next?

By lodging their appeal, the government is looking for an order to be made that sets aside the labour board’s original finding. They firmly believe that the Treasury Board did not act in bad faith [1].

PSAC remain adamant in their belief that the Treasury Board acted in bad faith. However, we will need to wait for the result of the appeal before any conclusions can be drawn.

There is currently no timeframe on when the Federal Court of Appeal will hear this case. Therefore, discussions and disagreements may be commonplace for some time.

Thinking Points

[1] The national dental care plan is proving to be a topic that is attracting substantial conversation. While we wait for the specific details of the plan to be worked out, it is important to not neglect your oral health in the meantime!
