University scientists have identified a gene responsible for initiating the normal development of tooth roots in mammals. Researchers made this discovery by creating a mouse lacking the gene ...

The interaction between Hertwig's epithelial root sheath (HERS) and surrounding mesenchymal cells is crucial for root dentin formation. HERS influences tooth root development and odontoblast ...

Beta-catenin is required in odontoblasts for tooth root formation, according to a new study in the Journal of Dental Research (January 23, 2012). While the molecular and cellular mechanisms of early ...

Teeth function not only because of the hard enamel on the surface, but also because they have roots that anchor them firmly in the jawbone beneath the gums. Eating, speaking, and maintaining the shape ...

A root canal is a dental procedure that gets rid of damage in your tooth’s roots while preserving your natural tooth. Root canals become necessary when infection or inflammation develops in the soft ...

A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published today in the journal Science. When completely ...
