up through the gums to replace the baby tooth. Eventually, a total of thirty-two permanent adult teeth form and erupt. The adult teeth are arranged in both the upper and lower jaws from the midline of the mouth as follows: central incisor, lateral incisor, canine (cuspid), first premolar...

Longitudinal ground sections of twenty mandibular deciduous teeth (4 of each tooth type) made through the crown in the buccolingual plane were selected that showed clearly visible daily enamel cross striations using transmitted polarised light microscopy. Ten average measurements, each one made across ...
A discovery in southern China of human teeth dated to more than 80,000 years old indicates that Homo sapiens was present in the region considerably earlier than had previously been suspected. See Letter p.696 Robin Dennell News & Views14 Oct 2015 Nature The middle Pliocene gets crowded Ne...
Understanding cell types and mechanisms of dental growth is essential for reconstruction and engineering of teeth. Therefore, we investigated cellular composition of growing and non-growing mouse and human teeth. As a result, we report an unappreciated cellular complexity of the continuously-growing mous...

The fact that in human teeth fractures are not often observed across rods, but primarily at the micro-scale interrod–rod interface67, demonstrates that the nano-scale toughening mechanism proposed here is effective. The mis-orientations observed within all rods may result from imperfect oriented ...
