A new documentary brings early human history to life with a "scientifically accurate" collection of hyper-real 3D models.

Pigs are the unlikely model for this latest research into regenerating human teeth. Image source: agnormark/Adobe In a recent study, Yelick and her team successfully grew human-like teeth in pigs.

Now that it’s possible to create teeth from bioengineered mouse stem cells, researchers are moving on to investigating the best methods to get future human versions into mouths.

The pig’s mouth revealed its ordinary sharp, tusk-like canines saddled up beside smaller, slightly more human-looking teeth nubs. In theory, a similar process could play out in humans.

Tufts University researchers took material from human and pig teeth and were able to grow a tooth-like structure. They hope their findings could lead to growing living tooth replacements for people.

Analysis Two-million-year-old teeth transform theory of prehistoric human evolution Changes in the appearance of ancient teeth could act as a new evolutionary marker, writes Ian Towle ...

An international team has unearthed new clues on early human development by analyzing fossilized teeth of early Homo specimens found in Georgia, dating back 1.77 million years. Utilizing advanced ...

The system can remove 100% of plaque on a 3-D printed model of human teeth and gums, and 80% in animal testing.

Why It Matters The ability to grow human teeth could significantly improve outcomes for patients who lose adult teeth because of injury, decay or disease.

The new model mimics the structure and function of the human conjunctiva in a lab dish, even producing its own tears.

It also hasn’t been demonstrated on humans just yet, and while the dentin that scientists grew on the animal models is extremely similar to human teeth, it isn’t exactly the same.

Researchers also believe the bacteria is not as commonly found within ancient teeth because the human diet included less refined sugar and fewer processed foods than are consumed today, Cassidy said.
