Mice deficient in the EDA protein lack normal tooth features. Restoring EDA in embryonic teeth at increasing doses has now been found to recover these dental features in a stepwise pattern that mimics ...

A study finds an early mammaliaform displaying tooth anatomy that gives insight into the development of structures such as complex molars and multiple roots. One evolutionary milestone in the ...

Using an atomic-scale imaging tool on a sea creature's tooth, two Northwestern University researchers have peeled away some of the mystery of organic and inorganic interfaces in tooth and bone ...

Though notoriously short-armed, the T. Rex had other genetic advantages: namely, its teeth. Researchers have found that the saw-like internal tooth structure of carnivorous dinosaurs like the ...

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 ...

The morphology of an animal's teeth often reflects its diet. A well-known example of a mammal that feeds in the water is the crabeater seal (Lobodon carcinophaga), which consumes large amounts of ...

Post and core is a dental restoration treatment that’s sometimes performed after a root canal. When a significant portion of a tooth’s structure is removed, a post and core can help keep a dental ...

Tooth decay is the destruction of tooth structure and can affect both the enamel (the outer coating of the tooth) and the dentin layer of the tooth. Tooth decay occurs when foods containing ...
