Often when a child injures their adult tooth, blood supply reduces and root development stops, resulting in a dead tooth. A new therapy, utilizing the child’s own stem cells, extracted from their existing baby teeth may hold the key to preventing a dead tooth. The stem cells extracted from the patient’s baby teeth are cultured, to increase stem cell volume, before implantation.
In a phase I trial, 40 children with injured front teeth entered a study, to demonstrate this new therapy. Thirty of the forty children were treated with the new stem cell therapy. The remaining 10 children received the traditional treatment for injured teeth (apexification). Researchers found those children who received the experimental treatment had thicker dentin development, increased blood flow and healthier root development – as compared to the control group.
As a side note: This therapy currently will not work in adults because they do not have any baby teeth, in which to extract stem cells. Researchers are currently working on using donated teeth stem cells, though these stem cells may get rejected by the body, due the incompatibility to the host immune system.
