"Professor Wang, look, this is the tooth we cultivate, and all functions are the same as those of the human body!"

In a large laboratory on the second floor of the Nandou Research Center, Wang Jia was wearing a sterile suit and stood next to a petri dish covered in glass, quietly watching the nutrient solution and a beige-white teeth in the petri dish.

Below the molars, the pulp cells and nerve tissue are also hung intact on the teeth, and even a few nerve tissues are spasmed from time to time.

"We have conducted a comprehensive examination. This tooth has all the functions of a normal tooth, the pulp tissue is complete, and the nervous system is also normal."

"This shows that our project is very successful! If it is not cultivated in vitro, but directly in the pulp cavity where the patient has lost its teeth, it can completely regenerate teeth for the patient!"

Wang Jia carefully looked at the artificially cultivated teeth in the Petri dish. The project was led by her, so she naturally knew the project situation.

"Prepare to apply for a clinical trial!" she said excitedly!

Although the problem of the small number of dental stem cells cannot be solved for the time being, it may be difficult for adults to repair and regenerate teeth, but underage teenagers can enjoy the convenience brought by dental regeneration technology!

The risk of dental regeneration projects is not high, and there are no potential side effects that can cause harm to the human body, so the application for clinical trials was quickly passed.

As soon as the clinical application was approved, Wang Jia immediately applied to Gusu Children's Hospital for clinical trials in this hospital.

Gusu Children's Hospital is also easy to talk about. Ruikang Group has the greatest influence on Gusu local hospitals now. No Gusu hospital can reject some of Ruikang's small requests, let alone conducting clinical trials, which is even more undesirable!

With the help of Gusu Children's Hospital, they soon contacted three young men aged 10-16 who had teeth defects due to accidents.

Among these three, two of them still have a few baby teeth, but they replaced the permanent teeth first, which caused defects and even removals due to accidents.

The other one is that all the deciduous teeth have fallen off and have been replaced with permanent teeth. However, his parents are very visionary. When the deciduous teeth fell off, they contacted the stem cell bank of the province to preserve the pulp stem cells of the deciduous teeth for the child to meet the prerequisites for tooth regeneration!

At present, because Wang Jia and the others are unable to induce somatic cells into pulp stem cells on a large scale, they can only require patients to have pulp stem cells themselves before they can receive dental regeneration treatment.

However, this embarrassment will not last too long. Since Chen Changan and Yun Heng are going to do an organ regeneration project, the first step is to solve the problem of inducing pluripotent stem cells. Then, learn it secretly from Chen Changan and change it, and you can use it to induce tooth stem cells.

So Wang Jiacai started clinical trials so easily.

Otherwise, according to the normal process, what she should do now is to overcome the problem of sparse endodontic stem cells.

.........

Half a month later, Gusu Children's Hospital.

In the dentistry on the third floor, three parents in their thirties each took their own children and were waiting in the lounge nervously.

Two of the three children are older, one is a boy, one is 16 years old, the other is 12 years old, and the youngest is a girl who is only ten years old.

Their missing teeth are different for different reasons.

The little girl has serious tooth problems, commonly known as tooth decay. She was originally in the dental change period. Some of the more severely corroded baby teeth were replaced with healthy permanent teeth after they fell off.

It was good originally, but because the little girl's parents were a little negligent and did not control her sweets, some of her permanent teeth were also seriously corroded, and even after several repairs, it was so serious that it had to be pulled out.

The permanent teeth are different from the baby teeth. Once they are removed, don’t think they will grow again. They will always be missing a tooth!

Moreover, because the child is still in the development stage, it is not suitable for filling her teeth at this time, because after making ceramic teeth, as the child grows up, the size of the teeth will change, and ceramic teeth will not grow with the child.

It is better to wait until the developmental period is over before filling the teeth.

However, although the permanent teeth that a girl wants to extract are the first molars, not the teeth that are made on the store, they usually cannot be seen as long as they don’t laugh brightly, but after all, they are girls. If they always lack a tooth, they will not look beautiful after all, and will also make the child feel inferior.

In addition to this little girl, the reason for the missing teeth of the other two boys is relatively simple, both of them are because of falling.

That's right, the child was playing and playing at school and accidentally fell down, causing his teeth to fall out directly.

Just like what was performed on TV, it spit out of the mouth...

Unfortunately, the two of them fell off their teeth just happened to be permanent teeth that had been replaced once, and they could no longer hope to grow again.

The two of them lost a central incisor (incisor) and a sharp tooth (tiger teeth) respectively. They are both the facades of the teeth, and they can be seen with just a little opening their mouth.

Since their teeth fell, the two of them rarely speak at school, let alone laugh.

After all, they are already in junior high school and high school. Most of the students of the same age have fallen off their baby teeth, especially the eight facade teeth, which have been replaced as early as the age of seven or eight.

This led to the lack of teeth in the entire school.

In school, the most taboo thing is to be unique. All the unique people will become the topic of conversation for all students in the whole school.

Naturally, they became the "unlucky guy who lacked teeth in a certain class" as their classmates said.

Over time, they naturally don’t want to show their teeth in front of their classmates, become taciturn, inferior and autistic.

The parents of children also see these things and feel uncomfortable. However, because they are still in the development stage, they are not suitable for making ceramic teeth, and the current situation cannot be changed for the time being.

Until, Ruikang's dental regeneration program launched volunteer recruitment for clinical trials!

After reviewing the records of previous cases, Gusu Children's Hospital called the three parents to ask whether they were willing to participate in this clinical trial.

There is no doubt that no parent does not want their children to grow up healthily, and they agreed without hesitation.

After making an appointment, the three groups of parents led their children to the Children's Hospital early in the morning, waiting for Ruikang's clinical trial of dental regeneration to begin!
Chapter completed!
