Dental Key
Dental Key (pronunciation: /ˈdɛntəl ki:/) is a historical dental instrument used primarily in the extraction of decayed teeth.
Etymology
The term "Dental Key" is derived from its resemblance to a large door key. The instrument was also known as a tooth key. The term "key" in this context is from the Old English "caeg", meaning a device to open or close a lock.
Description
The Dental Key is an instrument that was used in dentistry from the 18th century until the early 20th century. It consists of a handle, a shank, and a claw. The handle is typically made of wood or metal, while the shank and claw are usually made of metal. The claw is designed to grip the decayed tooth, which is then extracted by turning the handle.
Usage
The Dental Key was used by placing the claw around the decayed tooth. The handle was then turned, similar to turning a key, to extract the tooth. This method often resulted in the tooth being broken during extraction, and the instrument fell out of use with the advent of more modern dental extraction tools.
