Scientists have developed new regenrative dental fillings that can stimulate the native stem cells in the pulp to heal the damaged tooth and its surrounding dentin
A new study sheds light on the evolution of tooth enamel tissue. It turns out that the enamel protecting human teeth originated in the scales of ancient fish.
Using fossilized teeth, researchers found that humans adapted a grass-based diet 400,000 years earlier than previously thought. This sheds light on how habitat change shaped human evolution.
About 210 million years ago, the supercontinent of Pangea was just starting to break up. At the time, dog-sized dinosaurs hid from the predators at the top of the food chain: reptiles called phytosaurs and rauisuchids. Now, with the discovery of an ancient tooth, scientists have found that these predators may have interacted with each other far more often than previously thought.
Paleontologists have uncovered a massive fossil tooth belonging to a fearsome marine predator - a fossil that is the largest of its kind in the United Kingdom, researchers say.
