Why Does “Positive Stress” Actually Boost Tooth Tissue Regeneration?
12Sep
Recent research has found that “positive stress” can make good changes in tooth stem cells – which can make them more resistant to injury and disease. This boosts the potential of tooth regeneration too, and could help with more extensive research into tooth regeneration in the future. These findings come after a range of areas to do with cells and teeth were examined.

Stress is often seen as something negative. However, recent research has found that “positive stress” is capable of making good changes in tooth stem cells – which can make them more resistant to injury and disease [1].

In the past, when there have been issues with our natural teeth, it is common to turn to dentures or implants. But such research suggests that regenerating our natural teeth could be a possibility.

What happens when teeth get damaged?

The main research looks at the steps taken when teeth become damaged. When a tooth gets damaged, either through injury, trauma or decay, the tissue inside the tooth can become exposed to harmful bacteria. Moreover, it becomes vulnerable to infection.

If the tissue inside the tooth becomes fully infected, there are only a few current treatments. This includes a root canal treatment or extraction. At third option can be to remove the pulp in the tooth and fill the canal with artificial materials like rubber or cement.

This third option does however pose problems – as these artificial materials dry over time. Unfortunately, this means that extraction becomes likely – which is something all dentists try to avoid.

Therefore, scientists have looked for a long time at finding ways where a teeth is able to regenerate itself, and not need any manual work from dentists to do so.

The Research

The research was completed by a team from the Hong Kong University of Dentistry. Their work has been published in the Journal of Dental Research [1].

The authors acknowledged that the usual approach towards dental pulp regeneration – which involves stem cell-based therapeutics – has its limitations [1]. This is because a tooth’s root canal is surrounded by tissue with a limited blood supply, making it a harsh environment for any cells to be viable in. Moreover, with the low oxygen levels making it almost impossible for any cell transplant to thrive in.

The team instead used a technique where they modified the cells genetically, yet altered them to include a responsive state for low oxygen conditions – causing “stress” [1]. Therefore, this could theoretically help the cells to survive in the environment described above.

The research involved the root canal of a human tooth fragment being implanted into mice. The root canal was altered using the technique above. The researchers observed the mice, after 28 days they witnessed that tissue formation had occurred [1].

This research was able to show that such a technique appears to work. By adapting some elements in tooth stem cells, the stress was able to boost the regeneration of the tooth [1].

The researchers concluded that this positive stress could result in tooth stem cells becoming more resistant to disease and injury [1]. This would clearly have an excellent impact on teeth.

What this means

Overall, this research has been able to show that positive stress can have a positive impact on tooth stem cells, and can help to improve survival of teeth, and also play a potential role in tissue regeneration.

Dr. Dissanayaka is Assistant Professor in Oral Biosciences at Hong Kong University of Dentistry. He commented “former research has revealed that our cells possess (a) number of adaptive mechanisms for stress” [2].

But by pre-conditioning the cells genetically, this “significantly enhanced the dental hard tissue formation within the regenerated pulp tissue” – Dissanayaka says [2]. Continuing, he says that “tooth stem cells have an inherent capacity to survive under stress” [2].

Looking ahead, the authors aim to identify drugs that could be used in clinical tissue regeneration. This, along with the research carried out above, will help the team to form new strategies to improve the potential of tooth stem cells.

Thinking points…

1) The idea of tooth regeneration is certainly exciting. However, as always, the focus should be on prevention rather than treatment. The best way of preventing dental issues is to have strong oral hygiene, including brushing your teeth regularly, flossing, and eating healthily. Another hugely important aspect of strong oral health is to have regular dental check-ups. We should have a check-up at least twice a year, why not book an appointment now?

2) It is important to remember that unlike many parts of the body, a tooth won’t automatically recover if it becomes damaged. Despite the regenerative topics outlined above, it isn’t something we will see overnight. It can be tempting to avoid visiting the dentist if you are in pain, as you may think it isn’t necessary. But if you leave problems untreated, they will only get worse. Therefore, if you do need treatment, do ensure that you book in an appointment!

What Causes Bad Breath and What Can We Do About It?
28Aug
Bad breath is something that affects many of us – and we often don’t realize it either. There are many causes of bad breath – most of which are avoidable. Fortunately, there are a range of ways of improving our breath, which include dental treatment, improved oral hygiene and keeping hydrated.

Bad breath is a difficult thing to live with – and for some people, it is a huge problem that affects them socially and mentally.

One of the main issues of bad breath is that most of us can’t smell our own breath. Therefore, if it is bad, we are reliant on others telling us. But this isn’t an easy topic to broach, and often the problem is not brought up.

Bad breath, especially in the morning, is very common. For example, it is believed that around 60million Americans have chronic bad breath [1].

If you have bad breath, it is important to look at potential causes. Fortunately, there are many ways of improving bad breath, with dental interventions typically the most effective.

What causes bad breath?

The main cause of bad breath is the effects of bacteria in the mouth. Bacterial by-products from anything that enters the mouth create a concoction that cause a foul odour to emit from mouth. In many cases, it can make it smell like rotten eggs [2].

The main emitter of this foul odour is the tongue. This is where the majority of bacteria latch to. After all, the back of tongue is pounced upon by bacteria, as it is able to feed on dead cells, saliva proteins and fluids from untreated gum disease.

Eventually, the bacteria builds up to the extent where our breath becomes impacted. With the tongue placed in a way that it automatically emits out of our mouth, bad breath is inevitable if the tongue is in poor condition.

It is therefore very important to have excellent oral hygiene. This can help improve our breath. Another contributing factor to bad breath is food particles being left behind. Flossing can greatly improve this issue.

Then there are also other places for unhealthy bacteria to thrive in. These include spaces between broken fillings, holes in teeth (cavities) and pockets in the gums that form due to gum disease.

Many people find that their breath is particularly bad when they first wake up. Saliva flow stops or at least slows when we sleep. Therefore, with little saliva, our mouth dries. Dry mouth is a common side effect of many medications too [2]. Moreover, some people breathe through mouth rather than nose while asleep, worsening the problem.

Other causes of bad breath that are worth looking out for include strong-flavoured foods like curry, onion and garlic. Smoking tobacco is another common cause.

Things you can do

There are many easy and practical fixes. Chewing sugar free gum throughout the day and keeping the mouth hydrated with water can be very helpful.

Avoiding tobacco and strong-smelling foods also helps. If you do have these foods, using a mouth rinse afterwards can be helpful.

But the easiest way to avoid bad breath is to have strong oral hygiene. This includes brushing your teeth at least twice a day and flossing regularly.

But, there is only so much that we can all do. Sometimes, there are deeper causes, which is when a dentist can help.

What can a dentist do?

Attending a dental check-up can be very helpful. This gives a dentist the chance to look at the state of your oral health, and recommend treatment if necessary.

They are also able to locate anything that is contributing to the bad breath – for instance broken fillings, cavities and pockets in the gums. They can provide treatment when needed, which may help to improve our breath.

Your dentist may give you suggestions that can help with bad breath – including cleaning or scraping your tongue. This can be particularly helpful for bad breath.

By attending regular dental check-ups, it will ensure that your teeth remain in strong condition. This is the best way of preventing bad breath.

Thinking points…

1) Taking care of our oral health is so important! Not only can it help to prevent bad breath, but it can also have many other benefits. Therefore, make sure you have excellent oral hygiene – including brushing your teeth regularly, flossing, and as we mentioned earlier, consider using a tongue scraper. Ensure too that you attend dental check-ups regularly, as this will give your dentist a chance to look for any issues. Consider booking an appointment now!

2) While it isn’t an easy topic to bring up, if you know someone who has bad breath, consider having a quiet word with them. You could share this article with them, or recommend some of the practical fixes that are mentioned above. Most importantly, try to persuade them to book a dental appointment, as these can help a lot for overall oral health, including bad breath. While they may not appreciate your comments in the short-term, they will be thankful in the long run.

How Was the Mental Health of Dental Professionals During COVID-19?
2Aug
New research has showed the impact that Covid-19 had on dental professionals. While the focus of the media has mainly been on healthcare workers in hospitals, it shouldn’t be forgotten that dentists had an important role to play. The research has showed that many dental professionals struggled with symptoms of Anxiety and Depression during the pandemic. Fortunately, the Covid-19 vaccine appeared to improve their mental health.

Covid-19 has affected billions of people around the world. Many people lost loved ones, everyone had to change their daily lifestyle, and millions of jobs were lost. But for healthcare workers – they were suddenly launched without warning into tackling a pandemic.

Most of the focus of the media has been on the welfare and wellbeing of healthcare workers in hospitals. But very little focus has been placed on dental professionals – who also played an important part in healthcare throughout Covid-19.

However, new research has looked at how the mental health of dental professionals varied during a 12-month period of the pandemic. The findings showed that many dental professionals had symptoms of Depression and Anxiety [1].

Background

Covid-19 first appeared at the end of 2019, before spreading around the world in 2020. At the time of writing, there have been over 550million cumulative cases [2]. Tragically, there have been almost 6.4million deaths around the world [2].

Under the advice of the World Health Organization (WHO), routine dentistry was stopped in early 2020. But despite this, emergency dentistry continued, with those in severe oral pain still able to receive dental treatment.

Covid-19 is highly-contagious, and not everyone who carries it is aware they had the virus. Therefore, this meant it was highly likely that dental professionals would catch Covid-19, given the amount of human contact they had, and time spent in confined spaces.

This research involved looking at the symptoms of Depression and Anxiety. Symptoms of Depression include low mood, sadness, feeling hopeless, having no motivation and not getting any enjoyment out of life [3]. Meanwhile, the symptoms of Anxiety include restlessness, a sense of dread, feeling on edge, excessive worrying and physical symptoms like dizziness or shaking [4].

The Research

The mental health of most people suffered during Covid-19. This research looked at the mental health of dental professionals. Moreover, it specifically looked at whether or not the participants showed symptoms of Depression and/or Anxiety [1].

The research study was published in the August issues of The Journal of the American Dental Association and The Journal of Dental Hygiene [1]. The study itself was administered by researchers from the American Dental Association (ADA) [1].

The research involved 8,902 dental healthcare workers [1]. They all took part in monthly, anonymous web-based surveys, where they would log their feelings in relation to whether or not they were exhibiting signs of the symptoms of Depression and/or Anxiety [1].

The surveys took place over a 12-month period between June 2020 and June 2021 [1]. This time period was when Covid-19 was rampaging across the world, with healthcare services stretched to their capacity.

The results showed that dental professionals were affected by Covid-19 [1]. 17.7% of dental healthcare workers reported symptoms of Anxiety, while 10.7% reported symptoms of Depression [1].

The researchers found that the symptoms of Depression peaked in December 2020 [1]. The number of people with symptoms of anxiety also had high numbers in the final few months of 2020 [1].

Interestingly, the Covid-19 vaccine lessened the number of dental professionals with symptoms [1]. Healthcare workers were among the first to be offered the vaccine. However, unvaccinated dental workers who intended to be vaccinated – but had not yet received their vaccine – had noticeable anxiety, with a high mark of 20.6% of this group [1].

By the end of the study – at a time when the number of Covid-19 cases were dropping – 12.1% of dental professionals were still showing symptoms [1]. Hopefully, these numbers have lowered further in the year since the final survey.

What the research shows

Dealing with Covid-19 was clearly a significant challenge. While the threat is not yet over, case numbers have dropped significantly. The statistics above show that dental professionals faced many challenges too.

Stacey Derschewitz – Professor of Clinical Psychology at the George Washington University – commented on the findings. She said that “as the pandemic continues, it is critically important that dental health care workers continue to develop their ability to recognize and address signs and symptoms of mental health conditions within themselves and their colleagues, promote healthy work environments, reduce the impact of stress on the profession, and make supports accessible to those who are struggling emotionally” [5].

Dental professionals need to look out for one another, and take time out when they are struggling mentally. Open communication is important, and can hopefully provide dental professionals with the tools they need for improved mental health.

Thinking points…

1) While many people had their dental care interrupted during Covid-19, routine dentistry has recommenced, and it is therefore a good time to attend a dental clinic. We recommend attending a check-up, especially as some problems may have developed while routine dentistry was halted. Consider booking an appointment now!

2) Covid-19 impacted the mental health of many people. Remember to check-in with your friends and family, especially those who may be particularly struggling. Moreover, remember too that when seeing your dentist – that they will have been through a lot, and to respect them throughout your visit.

Is There a Link Between Gum Disease and Alzheimer’s Disease?
18Jul
Recent research has found a potential link between gum disease and Alzheimer’s Disease. The link is due to a specific type of bacteria – named Fusobacterium nucleatum. The study suggests this type of bacteria is very bad for us. Because of the outcome of this research, there are several oral health implications.

Recent research has found that a common type of bacteria may be the main factor behind the link between Gum Disease and Alzheimer’s Disease.

The name of the bacteria is Fusobacterium Nucleatum (F. Nucleatum). When a person has gum disease, F. Nucleatum spreads rapidly. It affects the gums and jawbone – and can eventually result in tooth loss.

Researchers have studied F. Nucleatum for a while, but the most recent research is a troubling case – with the theory now that there is a direct link between oral health and Alzheimer’s Disease.

Background

Gum disease is one of the most common conditions around the world. It is characterized by inflammation of the gums, and can cause pain, receding gums and bone problems.

Alzheimer’s Disease is a condition that is based around a steep cognitive decline, which can greatly impact a person’s life. Research shows that approximately 1 in 6 people over the age of 80 have Alzheimer’s Disease [1].

There are countless types of bacteria. Many are unfortunately bad for us – including F. Nucleatum. Bacteria can combine with acid and sugar to cause tooth decay, and is also linked to gum disease.

F. Nucleatum is seen as an especially bad bacteria. For example, past research has shown that F. Nucleatum is linked to conditions like Colorectal Cancer and the premature delivery of babies [2].

The Research

The research was published in the journal Frontiers in Aging Neuroscience [3]. It was completed by scientists at Tufts University, Massachusetts.

The researchers sought to see the impact F. Nucleatum had on gum disease, and to see if it could be connected to Alzheimer’s Disease [3]. To achieve this, the researchers induced several mice with F. Nucleatum, before tracking the development of the bacteria.

The researchers found that exposure to F. Nucleatum resulted in an abnormally-rapid spread of microglial cells – which are immune cells in the brain that are usually responsible for removing damaged neurons and infections whilst helping to maintain the general health of the central nervous system [3].

However, this over-supply of microglial cells resulted in an increased inflammatory response [3]. This was the worrying part for researchers – who mentioned that chronic inflammation is already known to be a key factor in the cognitive decline that occurs in those with Alzheimer’s Disease [3].

The researchers found that exposure to F. Nucleatum resulted in the mice having poorer memory and thinking skills [3]. While the researchers emphasized that they weren’t saying F. Nucleatum directly causes Alzheimer’s Disease, they did mention the impact that oral health plays in this sequence [3].

As gum disease is worsened by exposure to F. Nucleatum, for those that suffer, there is an increased risk that their inflammation will worsen – resulting in a higher chance of developing Alzheimer’s Disease [3].

What this means

The findings of this research are worrying. But the research does show how important looking after our mouth is. By having excellent oral hygiene, we are able to clean our mouth, and keep bacteria at bay.

The researchers suggested that treating gum disease in those who have early stage Alzheimer’s Disease could potentially slow the progression of the cognitive condition [3].

Jake Chen – a Professor of Periodontology at Tufts University – led the study [4]. He commented on the findings. He said that “testing for bacterial load and degree of symptoms could one day become a way to measure the effects of F. Nucleatum and manage treatment to slow progression of both periodontal disease and Alzheimer’s” [4].

Moreover, Chen’s team spoke about potentially looking at drug targets that could target the inflammation caused by F. Nucleatum. By doing so, Chen believes it will be possible to slow the spread and progression of both gum disease and Alzheimer’s Disease [4].

Chen’s laboratory have designed a small molecule called adipoAI, which has anti-inflammatory properties [4]. Chen aims to complete a study which will determine what impact this molecule could have on gum disease and Alzheimer’s Disease [4].

Moreover, past research is also relevant here. Previous research found that adults with missing teeth (commonly caused by gum disease) had a 1.48 times higher chance of cognitive impairment than the general population [5].

Hopefully, the research will show more people the importance of looking after their mouth. Oral health is crucial, and by taking care of our oral health, it can be excellent for our physical health too.

Thinking points…

1) Gum disease is a very damaging condition, but crucially, it is avoidable! One of the worst elements of gum disease is that many people do not realise they have the condition. Early detection is very important. The easiest way to see if you have gum disease is to attend a dental clinic for a regular check-up – your dentist will be able to give you an overview of your overall oral health. Therefore, we recommend you book an appointment now!

2) Do you know anyone with Alzheimer’s Disease? The findings of this article are especially important for those in the early stages of the condition – as good oral healthcare does appear to be able to slow the progression of Alzheimer’s Disease. Therefore, consider showing them this article, and urge them to visit their local dentist for a check-up. It could help them hugely!

Researchers Create New Treatment for Stopping Tooth Decay: Will It Work?
27Jun
Researchers in China have created a new treatment using a combination of agents and nanoparticles which is aimed at preventing tooth decay. Tooth decay continues to affect billions of people, so a treatment that claims to prevent it is promising. The treatment aims to stop the production of acidic substances and bacteria in the mouth. Therefore, this helps improve oral health.

New research has led to the creation of a treatment which aims to help prevent tooth decay. The research has the potential to have an excellent impact on the oral health of billions of people.

The treatment, which is the result of a mix of agents and nanoparticles, aims to stop the production of acidic substances and bacteria in the mouth.

By stopping the production of these harmful substances, the mouth will be less vulnerable to tooth decay. Therefore, this would hopefully lessen the number of cavity fillings that people require.

Tooth decay

This research is aimed at preventing tooth decay. Tooth decay results in the development of cavities in teeth, which require a filling to prevent further damage.

Tooth decay affects so many people around the world – from children to older adults. It is often caused by having too much sugary food and drink [1]. Moreover, poor oral hygiene will also often result in the development of cavities [1].

Bacteria and acid in the mouth – caused by food, drink, and other items placed in the mouth, also contribute to cavities. Therefore, dentists always preach the importance of eating healthily.

The Research

The researchers sought to find out if their treatment could help to prevent tooth decay. The researchers came from the Fujian Institute of Research. Their findings were published in the Chemical Engineering journal [2].

There was a special focus on preventing a specific type of bacteria caused Streptococcus mutans – which is known for its ability to survive in acidic environments, causing damage to the teeth and gums [2].

When there is too much bacteria, a “biofilm” is created, where teeth and gums become covered in bacteria and other microorganisms [2]. Therefore, bacteria can be very problematic.

The researchers developed their treatment using a few different substances. They loaded Rose Bengal – an antibacterial agent – onto Copper-doped Zinc Peroxide nanoparticles [2].

The researchers then sampled the use of their treatment on rodents [2]. Their combination was shown to be very effective. They found the nanoparticles were able to quickly produce hydrogen peroxide when exposed to the mouth. This helped to neutralise the acidic biofilm [2].

The treatment was able to kill large numbers of Streptococcus mutans in the mouth too [2]. Therefore, this had the effect where it became difficult for bacteria to build up – preventing tooth decay.

The combination of substances was effective at stopping the production of acidic substances and the formation of biofilm [2]. Overall, the findings suggested the treatment was highly effective.

Implications

The study produced very positive results. The results showed that a treatment of copper-doped Zinc Peroxide and Rose Bengal can be very effective for bacteria-based conditions [2].

Professor Chen Zhuo of the Fujian Institute, commented on the findings [3]. He said that an application of their treatment “effectively inhibited the occurrence and severity of dental caries without harmful effects on the body” [3].

For oral health, the findings are very positive. This treatment – which could potentially be used in the form of a toothpaste – could aid the prevention of bacteria building up. Therefore, tooth decay should lessen, causing fewer dental problems.

Thinking points…

1) Tooth decay is clearly a big problem, and many people are actually unaware that they have decaying teeth. Therefore, it is crucial to see a dentist for a check-up on a regular basis. By seeing your dentist, they can check for any problems or signs of decay, and offer advice where necessary. We recommend booking an appointment soon!

2) This article talks about bacteria in the mouth. It is important to remember that anything we put in our mouth – from food to drink to even our nails, results in bacteria entering the mouth. Think about your habits, is there anything you can do to lessen the level of bacteria entering your mouth? If you’re worried about this, we recommend talking to your dentist, who can offer practical advice. Why not make contact right away?

What we offer at Savanna Dental

Savanna Dental is a Calgary Dental Clinic that provide its patients with a range of treatment options and advice aimed at improving oral health.

It is crucial to brush your teeth at least twice a day and to floss regularly. Moreover, eating healthily and trying to avoid sugary foods and drink is important.

Why Is the Conflict in Ukraine Affecting Root Canal Dental Treatments?
13Jun
The ongoing conflict in Ukraine is having a substantial effect on multiple areas all over the world. Unfortunately, the healthcare system is not immune from its impact. Now, there are concerns that shortages caused by the conflict could impact dentistry – with more complex interventions like root canal treatments being affected.

The ongoing conflict in Ukraine is causing many issues around the world. While some of these effects – such as the emerging humanitarian crisis engulfing the country – are visible, other effects are not.

Among the areas that have been negatively impacted is the worldwide healthcare system. Unfortunately, the dental industry is also being affected by the consequences of the conflict.

Ukraine and Russia – the two countries involved in the conflict – are huge exporters of key commodities, including some items and materials that are used in healthcare.

Therefore, dental treatments are among the areas to be affected. More complex procedures like root canal treatments are likely to be the worst affected.

Commodity Issues

Towards the end of February 2022, Russia launched an invasion of Ukraine. The conflict has been going on for several months, with the Russian offensive met by strong resistance from the Ukrainian military.

As a result, the world has been impacted enormously. There have been concerns over a potential nuclear war, record high gas prices and a range of shortages. Therefore, many industries have been impacted – including the dental industry.

Russia and Ukraine are key exporters of some commodities. For example, in this case, the key resources are Ammonium Nitrate and Natural Gas [1]. But international sanctions, transport issues and procurement struggles has led to shortages. As a result, accessing these commodities has become more difficult.

When the above commodities are refined, they can produce two gases which are vital for the healthcare system. These are Nitrous Oxide (known as Laughing Gas) and Helium [1]. Both of these are used in millions of healthcare procedures each day.

Other Healthcare shortages

The Covid-19 pandemic had disastrous effect on worldwide supply chains, causing huge shortages [2]. These shortages have now been exacerbated by the conflict in Ukraine.

Since the invasion began, even more shortages have been reported. For example, baby formula, medication, and contrast dye used in diagnostic scans are among the current shortages. As a result of the contrast dye shortage, potentially life-saving scans are having to be rationed in some states – a dire situation [1].

The impact on dentistry

Nitrous Oxide is primarily used in dentistry for complex procedures or surgeries. Unfortunately, around 40% of Ammonium Nitrate – which is needed for Nitrous Oxide – comes from Russia [1].

Root canal treatments are used to treat an infection in the tooth. It involves a dentist removing infected soft tissue inside the tooth – known as the pulp [3]. Because of the invasive nature of a root canal treatment, as well its long procedure time, it can cause anxiety and concern from patients [1].

When patients are anxious, nervous or distressed, they can be offered a sedative – such as Nitrous Oxide. However, because of the shortages, less sedatives are expected to be available. This may result in less people wanting to undergo root canal treatment.

This shortage is therefore causing concern in healthcare. It is important to remember that dental clinics typically do have other sedatives available, but supplies are normally limited.

Regardless of potential shortages, dental clinics will aim to continue providing root canal and other complex treatments. This shouldn’t stop the overall goal of providing effective and efficient treatments for patients around the world.

Thinking points…

1) This article talks about root canal treatments. They aren’t pleasant procedures, but fortunately – they can normally be avoided through strong oral hygiene. As part of having a strong oral hygiene routine, you should ensure you see your dentist regularly for a check-up. If there are any problems that need addressing, your dentist will be able to spot them and suggest treatment if necessary. Therefore, this will prevent problems worsening – we recommend booking an appointment soon!

2) Maybe some of you reading this will be awaiting, or are in need of, root canal treatment. It can be tempting to avoid the dentist when you are scared ahead of a procedure. However, it is important that you go ahead and get the root canal treatment done. Unfortunately, dental problems won’t go away, and the longer you leave it for, the more damage will be done. Try to attend the appointment and if needed, discuss taking a sedative with your dentist.
