A set of human teeth under an orthopantomogram. Tooth regeneration is a stem cell based regenerative medicine procedure in the field of tissue engineering and stem cell biology to replace damaged or lost teeth by regrowing them from autologous stem cells.
By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready ...
The crown of the tooth, which is influenced by the shape of the inner enamel epithelium, also takes shape during this stage. Throughout the mouth, all teeth undergo this same process; it is still uncertain why teeth form various crown shapes—for instance, incisors versus canines. There are two dominant hypotheses. The "field model" proposes ...
2009 – from the stem cells were grown full teeth in mice, and even managed to grow a tooth root, previously it was not possible, but there is a problem, it is that grown teeth were slightly less "native" teeth. [1] 2013 - Chinese scientists grow human teeth in mice using stem cells taken from human urine. [2]

Researchers are confident that tooth regeneration technology can be used to grow live teeth in people. In theory, stem cells taken from the patient could be coaxed in the lab turning into a tooth bud which, when implanted in the gums, will give rise to a new tooth, and would be expected to be grown in a time over three weeks.

This can be quite similar to the role of blood clot in other injury site in the healing process. To prove this hypothesis, mature teeth diagnosed with pulpal disease received pulp space debridement followed by enlargement of the apical foramen. Medicament dressing was placed and intracanal bleeding was evoked.
Humans can live with one lung, the remaining one will expand and partially fill the rest of the chest cavity, which can lead to cardiac distress. It's not the most pleasant existence, but people ...
