Stem Cells Dental Fillings

July 5, 2016 By Waleed Javed

The bioactive dental fillings could decrease the frequency of visits to the dentist and save the tooth.

Scientists tested a new teeth treatment that involves using stem cells as dental fillings. The practice could end the need for root canals.

Researchers from Harvard University and the University of Nottingham won the Royal Society of Chemistry prize for their discovery. The winning includes media support, business training and support, and a cash prize.

The new tooth fillings will use stem cells to stimulate the growth of dentin. Patients will be able to regrow the teeth that had been damaged.

The Traditional Treatment

The traditional treatment for cavities involves drilling out the affected dentin and filling the hole with a chemical composition. It is profoundly disturbing for patients, and it usually does not stop the decay.

In case the intervention does not succeed, and the tooth still gets sick, dentists remove the pulp from the root canal. This ultimate solution brings additional damage to the tissue, and the tooth becomes more and more fragile.

The classic dental fillings rely on materials that should restore the function, the morphology and the integrity of the tooth. However, they often become toxic to teeth and the organism rejects the active substance.

If the dental pulp is damaged, a root canal is needed to extract the infected tissue, and the process is irreversible.

Dental Fillings with Stem Cells

The scientists designed biomaterials that can be used just like traditional dental feelings. The difference is that they stimulate the stem cell population to repair the tissue, which means that the tooth could be able to grow itself back on the inside.

The bioactive fillings could be used for both dental disease treatments and dental surgery.

The stem cells will bring the regeneration of the dentin and the pulp. They will effectively help the tooth to restore itself to its initial form, and leave no cavities and vulnerable empty spaces in the roots or the dentine layer.

The discovery could initiate a new field in dental care, the restorative dentistry, which is regarded with high hopes as the pulp cannot restore itself like other tissues inside the human body. Once a tooth is damaged, the process of decay cannot be stopped, and it usually ends up with an unpleasant empty space.

Researchers are now discussing with industry partners to make the new material available for patients.

As the last year’s winner managed to secure a funding of $1.7 million from the Gates Foundation, it may be that the new bioactive dental treatment will be introduced on the market relatively soon.

Stem Cell Factories Are a Reality

July 23, 2015 By Waleed Javed

Stem Cell Factories

A new technique allows the production of billions of stem cells. The newly created process might lead to the construction of stem cell factories, as claimed by researchers.

Heart attacks are usually responsible for the death of around 5 billion cells in the heart. It is possible that stem cells might be able to replace the dead heart cells in the cardiac tissue. This means that stem cells could be able to repair the damage caused by a heart attack. And this might tremendously benefit the patients who undergo these kinds of procedures.

Stem cells that are pluripotent can develop into any kind of cell, from bone and nerves to heart tissue. For a long time now, scientists have been working on an attempt to create a polymer able to serve as a layer on which to grow the very versatile cells.

The capacity to grow billions of cells easily and quickly might possibly lead to great advances in the restorative treatments for numerous injuries and conditions. Now, through the new process developed by the scientists it seems that stem cell factories are a reality.

Morgan Alexander from the University of Nottingham said that regenerative medicine is still being analyzed through the help of clinical trials. What is happening right now is paving the way to manufacture stem cells in huge numbers for the moment when those therapies are going to be proved to be effective and safe.

The new material developed by the scientists in the course of a $3.68 million research is free of contamination and variability. The new process reveals promise of it being scalable. This could potentially allow the development of stem cell based treatments both inexpensive and fast. Should the new technology be approved, it could be utilized to give treatments to patients in a period of only two to three years, said the scientists.

The University of Nottingham have said in an online statement on its website that the new material could be an off the shelf product for use in treating the brain, liver and heart.

Stem cells can be found in both adult and embryonic varieties. Each of these types of stem cells has unique properties that give out opportunities to be used in medicine. However, the embryonic stem cells are a lot more versatile than the adult cells.

If there will be stem cell factories in the future, the new technology will greatly benefit patients who suffer from brain, liver or heart conditions.
