Remains from ancient China (dating 4000 years ago) have carved bamboo pegs, tapped into the bone, to replace lost teeth, and 2000-year-old remains from ancient Egypt have similarly shaped pegs made of precious metals. Some Egyptian mummies were found to have transplanted human teeth, and in other instances, teeth made of ivory.
Evidence of this ancient connection includes a 10,000-year-old louse found on human remains at an archaeological site in Brazil and an inscription on a 3,700-year-old ivory lice comb that might be ...

Additionally, the evolution and reduction in the jaw has left little room for the third molar, or wisdom tooth, to form. As a result, many individuals choose to remove them through surgery. One of the defining features among Homo sapiens is the presence of a chin. A protruding chin was absent in archaic hominids, as well as Neanderthals ...
Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
As in most members of eugeneodontida, the smaller teeth found near the anterior end of the whorl represent the oldest teeth, which the animal grew as a juvenile and the larger and younger teeth found near the back of the whorl represent teeth grown in adulthood. An interesting distinction of Toxoprion are that its older anterior teeth typically ...
