Today there is another source to extract stem cells, beyond the blood and umbilical cord tissue at birth. Thanks to scientific advance, there is the technology to extract mesenchyme stem cells from the dental pulp.
This type of cells are capable of regenerating all types of tissues, being used with great potential in regenerative therapy, field where medicine has made more progress, helping to improve the quality of life of people.
Although in childbirth – a unique moment in life – it is possible to obtain this type of cells (mesenchyme) and also hematopoietic, useful to treat leukemia and other pathologies to the blood, preserve the stem cells of the teeth is an excellent alternative.
According to figures from the National Institute of Statistics (INE), the number of children in Chile represents approximately 20% of the total population, about 4 million. This segment today has the option of taking advantage of its mixed dentition stage – from 6 to 12 years old – to save its stem cells.
Many parents do not know that dental pulp is rich in mesenchyme stem cells. Therefore, we leave a series of recommendations and tips on the subject that Alejandro Guelf, Medical Director of Vidal, stem cell bank:
How are the stem cells obtained from the teeth?
To obtain a dental piece, which allows the extraction of stem cells from your pulp, it is necessary to go to a specialized doctor in the area so that you can evaluate and extract the tooth in a sterile way. Afterwards, the sample is transferred to a bank of stem cells. There, it is subjected to strict controls that comply with international standards that allow to determine the quality and quantity of the sample obtained from dental pulp stem cells. After being processed, the sample is cryopreserved in liquid nitrogen at -196 ° C, thus ensuring its correct maintenance and protection for future use in treatments.
What are these types of tooth cells for?
They are especially useful for therapies in the area of orthodontics, since they are capable of rapidly and efficiently increasing or regenerating bone tissue and dentin formation (internal part of the tooth). Therefore, its use is recommended even for complex cases where the absence of bone makes implant placement difficult, in patients suffering from periimplantitis, a disease that causes bone loss, when it is necessary to regenerate the alveolar bone or elevate the maxillary sinus.
Are they used for treatments not linked to dental problems?
These cells have had good results in orthopedic and traumatology therapies, mainly in the treatment of choral lesions, bone lesions, chronic spinal cord trauma and tedious pathologies. In addition, its use in various treatments in regenerative medicine is under clinical investigation.
What to do if your baby teeth have already fallen?
If you have already passed the stage of mixed dentition of your child, it is still possible to take advantage of this source when extracting the wisdom teeth, which also contain these mesenchyme stem cells rich in properties and benefits. As in the stage of tooth fall, the extraction must be done by a dentist and coordinate with it the delivery of the tooth to a bank of stem cells.
What is the best stage of life to save stem cells?
Over time, even stem cells suffer from the environmental aggressions that age all our cells. Storing the stem cells in an early state allows them to be stored at their best capacity, so the earlier you do it, the better.
