Scientists have looked our ancestors in the mouth and extracted a new insight about human evolution. Slowed-down tooth growth, a marker of extended childhood development in humans, emerged by only ...

Two distinct stem cell lineages that drive tooth root and alveolar bone formation have been identified by researchers from Science Tokyo. Using genetically modified mice and lineage-tracing techniques ...

A hypothetical model illustrating how reduced Hedgehog signaling alters interactions between the rudimentary tooth bud (R2) and the first molar (M1), leading to supernumerary (SN) tooth or molar ...

A simple, straightforward developmental rule -- the 'patterning cascade' -- is powerful enough to explain the massive variability in molar crown configuration over the past 15 million years of ape and ...

Tooth loss affects millions around the world, caused by decay, gum disease, injuries, and some diseases. Missing teeth do more than make it hard to chew or talk. They also impact appearance and ...
