stem-cell-dental-implants.jpg Stem cell research in coming days is likely to replace dental implants. Studies have shown that stem cells derived from the roots of removed teeth have shown to grow, new roots in mammals. The researchers headed by Songtao Shi from The University of Southern California have achieved significant strides in this regard. Stem cells are derived from root apical papilla (tissue at the tip of the root).

New Developments
a. The apical papilla cells (tissue at the tip of the root) are younger stem cells than cells derived from dental pulp. Thus is best for tissue regeneration. It results in formation of all root tissues, including dentin and cementum.
b. The study found that after implantation of stem cells, within 6 months the teeth has become strong enough, sufficient to cope up with normal wear and tear.
c. Experts have suggested that the new bio-root is recommended over dental implants as the bio-root has more natural relationship with the bone.
d. The new bio-root does not have the risk of gum disease or teeth loosening, unlike the implants.
e. In future the new technology could make root canal treatment less invasive and even repair decayed dentin.
