Human teeth could eventually be made to regrow, as we still possess the genes that allow regrowth

[barryqwalsh]

Sharks and other fish regrow their teeth repeatedly through their lives while humans have the capacity to regrow their teeth just once.

But now scientists at the University of Sheffield have discovered that the same network of genes that allow sharks to regrow teeth is present in humans.

Great news for meth heads and rednecks.

Was reading yesterday that they were doing more research if the victims of mount Vesuvius (Pompeii) and found out why they had perfect teeth, no super in their diet, mostly just fresh fruit and vegetables.

The discomfort and stigma of loose or missing teeth could be a thing of the past as Griffith University researchers pioneer the use of 3D bioprinting to replace missing teeth and bone.

If you’ve had teeth or part of a jaw replaced yourself, you’ll know that the current method is everything but easy on the patient. “In many cases there is not enough bone for dental implant placement, and bone grafts are usually taken from another part of the body, usually their jaw, but occasionally it has to be obtained from their hip or skull,” the professor explains. “These procedures are often associated with significant pain, nerve damage and postoperative swelling, as well as extended time off work for the patient.”


3D bioprinting can avoid that strain on the patient, while also ensuring a perfect fit. “The groundbreaking approach begins with a [CT scan] of the affected jaw, prior to the design of a replacement part using computer-assisted design,” he says. “A specialized 3D bioprinter, which is set at the correct physiological temperature (in order to avoid destroying cells and proteins) is then able to successfully fabricate the gum structures that have been lost to disease - bone, ligament and tooth cementum - in one single process. The cells, the extracellular matrix and other components that make up the bone and gum tissue are all included in the construct and can be manufactured to exactly fit the missing bone and gum for a particular individual.”

Australian researchers believe they are on the brink of being able to use stem cells to regrow human bone and tissue damaged by injury, illness or old age.

The team from the University of New South Wales says the stem cell repair system is not all that dissimilar to the way a salamander will regrow a leg or its tail when they're removed.

Lucy Carter has more.
