Physicists and mathematicians use the classical Stefan problem to explain the principles of crystal formation, such as snowflakes. Researchers in the University of Helsinki and Aalto University have ...

Scientists have identified a gene responsible for the formation of enamel, which is the key component of the teeth. The experiments were accomplished in mice carrying a deletion of the transcription ...

Biologists report new evidence for evolutionary change recorded in both the fossil record and the genomes (or genetic blueprints) of living organisms, providing fresh support for Charles Darwin's ...

ACCOUNTS have been already published of the effects of vitamin D, alteration of the Ca : P ratio of the diet, and dietary restriction, upon the dentin of the incisors of rachitic rats 1. It was noted ...

Enamel, the hardest and most mineral-rich substance in the human body, covers and protects our teeth. However, in one out of every 10 people—and in a third of children with celiac disease—this layer ...

The enamel that gives our teeth their bite evolved from the scales of ancient fish that lived more than 400 million years ago, fossil and genetic evidence suggests. Enamel is the hardest tissue ...

The U.S. National Institutes of Health National Institute of Dental and Craniofacial Research (NIDCR) has awarded a five-year, $2.3 million grant renewal to New York University (NYU) College of ...

Tooth enamel, made from tightly packed hydroxyapatite nanorods, is one of the hardest and most durable materials produced biologically. Exactly how it is manufactured in the body is still a mystery.

Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, John Bartlett, ...

To the naked eye, enamel looks like a plain white solid. Chemically, though, enamel has a lot going on. It contains small amounts of proteins, traces of ions such as sodium, as well as water. Mostly, ...
