The tooth fairy is a welcome guest for any child who has lost a tooth. Not only will the fairy leave a small gift under the child’s pillow, but they be assured of a replacement tooth in a few months. Unfortunately, the scenario is quite different for adults grappling with a loss of teeth. Luckily, there may be some hope thanks to a new study performed by scientists at Kyoto University and the University of Fukui.
A dental breakthrough
While the typical adult mouth houses 32 teeth, approximately 1% of the population exhibits variations of them, either possessing more or fewer teeth due to congenital conditions. Researchers have delved into the genetic factors behind cases of excessive teeth, seeking valuable insights into the potential regeneration of teeth in adults. This study is the first to show that monoclonal antibodies can help regrow teeth. It suggests a new way to treat a dental problem that currently requires implants and other artificial solutions.
A bit of science
The research team disclosed that an antibody targeting a specific gene, known as uterine sensitization-associated gene-1 (USAG-1), can induce tooth development in mice affected by tooth agenesis, a congenital condition. The findings were published in the journal, Science Advances.
As per Katsu Takahashi, a senior lecturer at the Kyoto University Graduate School of Medicine and one of the principal contributors to the study, the essential molecules crucial for the development of teeth have already been pinpointed. “The morphogenesis of individual teeth depends on the interactions of several molecules including BMP, or bone morphogenetic protein, and Wnt signaling,” says Takahashi.
On April 13, 2021, the University of Kyoto posted its first pic of newly-grown teeth in mice.
BMP and Wnt are involved in more than just tooth development; they affect the growth of organs and tissues early in the body’s development. Because drugs affecting them directly might have broad side effects, scientists are cautious. To find a potentially safer method, researchers focused on the gene USAG-1, thinking that aiming at factors countering BMP and Wnt specifically in tooth development could be more precise.
“We knew that suppressing USAG-1 benefits tooth growth. What we did not know was whether it would be enough,” added Takahashi.
The first results
Scientists looked at how different monoclonal antibodies affect USAG-1. Monoclonal antibodies are often used to treat things like cancer and arthritis and for making vaccines. Tests with this antibody showed that BMP signaling is crucial for deciding the number of teeth in mice. Also, just one treatment was enough to grow a whole tooth. Further tests confirmed these positive results in ferrets too.
“Ferrets are diphyodont animals with similar dental patterns to humans. Our next plan is to test the antibodies on other animals, such as pigs and dogs,” explained Takahashi.

The next steps
Now, scientists are going to test the drug on healthy adults. If that goes well, the team plans to try it on kids aged 2 to 6 with a rare tooth problem called anodontia, a genetic disorder defined as the absence of all teeth. These kids will get one shot of the drug to see if it makes their teeth grow. If everything works out, the medicine might be approved by 2030.
Takahashi sees the new medicine as an additional choice for individuals who are missing some or all of their teeth.
“The idea of growing new teeth is every dentist’s dream,” Takahashi told the Japanese newspaper, The Mainichi in June this year. “I’ve been working on this since I was a graduate student. I was confident I’d be able to make it happen.”
So hopefully, by the year 2030, humans will get a chance to have their third generation of teeth grown and say goodbye to implants. Until then, make sure to keep your teeth strong and healthy — this article will help you with that.

The Meaning of the Three-Dot Tattoo: A Comprehensive Guide to Russian Prison Tattoos
Are you curious about the fascinating world of Russian prison tattoos? One of the most intriguing symbols you may come across is the three-dot tattoo. In this article, we will explore the various meanings behind this unique tattoo design.
Symbolism and Interpretations
The three-dot tattoo holds different meanings, each with its own significance. One interpretation is its connection to the Buddhist monkeys, which symbolize secrecy and silence. This meaning suggests that individuals with this tattoo prefer to keep their personal lives private.
Another interpretation is related to the number of dots in the tattoo. It can represent the length of a person’s prison sentence. The more dots there are, the longer the individual has spent behind bars. This symbolism serves as a reminder of their past experiences and the challenges they have faced.
The Harsh Reality of Prison Tattoos
Tattoos in prison are not created under ideal conditions. They are often done using improvised tools and in unsanitary environments, making them difficult to remove. These tattoos serve as permanent reminders of a person’s time in prison and the struggles they have endured.
Stigmatization and Discrimination
While these tattoos hold symbolic meanings within the prison community, they can also lead to stigmatization and discrimination for former inmates in the outside world. Society may judge individuals based on their tattoos, making it harder for them to reintegrate into society and find employment.
It is important to understand the significance of these tattoos, but it is equally crucial to treat individuals with empathy and respect, regardless of their past experiences.
Join us on this journey as we delve deeper into the captivating world of Russian prison tattoos and uncover the meanings behind these intriguing symbols.
Stay tuned for more fascinating insights and stories!
Removing Prison Tattoos
Removing prison tattoos can be a difficult process. These tattoos are often done under harsh conditions, using improvised tools, and with poor hygiene. As a result, they are usually not aesthetically pleasing and can also pose health risks. However, professional tattoo artists can use laser technology to specifically target the ink particles and gradually remove the tattoo. It is important to note that this process often requires multiple sessions and can be painful.
Examples from Criminal History
There have been cases where tattoos have played a role in solving crimes. For example, a robbery at a gas station in Berlin was solved thanks to the distinctive neck tattoo of the perpetrator. Similarly, in the United States, a detailed chest tattoo led to the conviction of a gang member for murder. These various interpretations and examples demonstrate that prison tattoos not only have a long-standing tradition but can also be helpful to law enforcement agencies in solving crimes.
The Deeper Meaning of the Three-Dot Tattoo: A Trace of Crime and Freedom
The three-dot tattoo on the left hand is one of the most well-known prison tattoos and carries a deep symbolic meaning. The three dots represent the three wise monkeys from Buddhism, who see no evil, hear no evil, and speak no evil. This depiction symbolizes silence about criminal activities and turning a blind eye to crime within the prison community. It serves as a sign of loyalty among criminals and acts as a recognition mark in the outside world.
The Meaning of the Prison Tear
Another common interpretation of the three-dot tattoo is related to the so-called prison tear. After ten years of imprisonment, an inmate is allowed to have a tear tattooed to mark their time in prison. The longer someone has spent behind bars, the more tears can be added. This tattoo thus symbolizes the severity of the committed crime and the lengthy stay in prison.
Tattoos as Stigmatization for Former Inmates
Although prison tattoos are often done under difficult circumstances, they serve as recognition marks among inmates in the outside world. However, these tattoos also stigmatize former inmates and can lead to prejudice and discrimination. The visible tattoos make it difficult to integrate into society and lead a normal life after serving a prison sentence.
In conclusion, the three-dot tattoo holds various meanings and symbolizes secrecy, loyalty, and the length of a prison sentence. It is important to note that these interpretations can vary from region to region and from person to person. Nevertheless, the three-dot tattoo remains a well-known symbol associated with prison and is often linked to a criminal past.
The three-dot tattoo holds a deep meaning and has various interpretations, depending on the context and individual perspective. It is often associated with the prison system and criminal activities but can also symbolize personal identity and rebellion.
The Origin and Symbolism of the Three-Dot Tattoo
The three-dot tattoo, typically placed on the left hand, has its roots in Buddhist symbolism. It represents the three wise monkeys who see no evil, hear no evil, and speak no evil. In this context, the three dots symbolize a rejection of violence and wrongdoing.
Connection to Prison and Criminality
The three-dot tattoo is commonly linked to the prison system and is considered a mark for serious offenders. It is said that each dot represents ten years of imprisonment, with additional dots being added for longer sentences. For former inmates, this tattoo can serve as a symbol of their criminal past and may be perceived as a stigma.
Individual Interpretation and Identity Formation
Despite its association with criminality, the three-dot tattoo can also be individually interpreted. Some people choose this tattoo for aesthetic reasons or to express their rebellious nature. For them, it is a symbol of personal identity and self-expression.

The three-dot tattoo carries an ambivalent meaning in society. While it can be an interesting symbol of identity for some, others associate it with crime and violence. The interpretation and perception of this tattoo heavily depend on individual experiences and prejudices.
Dealing with the Three-Dot Tattoo
It is crucial to remember that not everyone who has a three-dot tattoo is necessarily a criminal or has a criminal past. Each person has their own story and reasons for choosing their tattoos. Therefore, it is advisable not to judge hastily and stigmatize people based on their appearance.
Conclusion
In conclusion, the three-dot tattoo is a symbol with a complex meaning that can be associated with both criminality and individual identity and rebellion. It is important to consider the various interpretations and contexts to avoid prejudices and stigmatizing people based on their outward appearance.
To summarize, the three-dot tattoo symbolizes strength, resilience, and overcoming obstacles. It serves as a personal statement of individual experiences and can hold different meanings depending on who wears it. It is a versatile tattoo with deep symbolic significance.
