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.
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.
Craniofacial surgery is a surgical subspecialty that deals with congenital and acquired deformities of the head, skull, face, neck, jaws and associated structures. Although craniofacial treatment often involves manipulation of bone, craniofacial surgery is not tissue-specific; craniofacial surgeons deal with bone, skin, nerve, muscle, teeth, and other related anatomy.
Teeth were another skeletal body part that was modified, usually by filing the tooth. Precious stones were often placed into bored holes in the teeth; some precious stones were jadeite, pyrite, or turquoise. This practice was most likely done when an individual was reaching young adulthood, as can be determined through the dating of the teeth ...
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 ...
An infected tooth from Italy partially cleaned with flint tools, between 13,820 and 14,160 years old, represents the oldest known dentistry, [33] although a 2017 study suggests that 130,000 years ago the Neanderthals already used rudimentary dentistry tools. [34]
Two rows of teeth are supported by facial bones of the skull, the maxilla above and the mandible below. Adults have 32 permanent teeth, and children have 20 deciduous teeth. There are various tooth shapes for different jobs. For example, when chewing, the upper teeth work together with the lower teeth of the same shape to bite, chew, and tear food.
