tooth

Examples of tooth in the following topics:

• Root Canal Therapy

  • Endodontic therapy is the treatment for the pulp of a tooth which results in the protection of the decontaminated tooth.
  • With the removal of nerves and blood supply from the tooth, it is best that the tooth be fitted with a crown which increases the prognosis of the tooth by six times.
  • Sometimes the dentist performs preliminary treatment of the tooth by removing all of the infected pulp of the tooth and applying a dressing and temporary filling to the tooth.
  • An infected tooth may endanger other parts of the body.
  • Because this is a "baby" tooth, the tooth was removed, but if this decay existed in a permanent tooth, a root canal would be required.

• Dental Caries

  • If left untreated, the disease can lead to pain, tooth loss, and infection.
  • To be specific, a tooth (which is primarily mineral in content) is in a constant state of back-and-forth demineralization and remineralization between the tooth and surrounding saliva.
  • The affected areas of the tooth change color and become soft to the touch.
  • Ninety-six percent of tooth enamel is composed of minerals.
  • (A) A small spot of decay visible on the surface of a tooth.

• Gomphoses

  • A gomphosis is a joint that anchors a tooth to its socket.
  • Gomphoses line the upper and lower jaw in each tooth socket and are also known as peg and socket joints.
  • Each tooth has bony protrusions or pegs that latch into the socket with the assistance of the gomphosis.
  • The gomphosis is made up of fibrous tissue, a collection of tough ligaments that attach to the socket and base of the tooth.
  • Chronic dental problems may loosen the ligaments and lead to tooth loss or instability.

• Tooth and Gum Infections

  • The mouth contains a wide variety of oral bacteria, but only a few specific species of bacteria are believed to cause tooth and gum infections.
  • This usually happens from the production of acid by bacterial fermentation of the food debris accumulated on the tooth surface.
  • If left untreated, the disease can lead to pain, tooth loss, and infection.
  • Bacteria occupy the ecological niche provided by both the tooth surface and gingival epithelium.
  • This image shows destruction of a tooth by cervical decay from dental caries.

• Periodontal Disease

  • In some people, gingivitis progresses to periodontitis –- with the destruction of the gingival fibers, the gum tissues separate from the tooth, forming pockets between the tooth and gum.
  • Although the primary cause of both gingivitis and periodontitis is the microbic plaque that adheres to the tooth surface, there are many other modifying factors.
  • Flossing daily and using interdental brushes as well as cleaning behind the last tooth, the third molar, in each quarter.
  • This radiograph shows significant bone loss between the two roots of a tooth (black region).
  • The spongy bone has receded due to infection under the tooth, reducing the bony support for the tooth.

• Ivory Carving

  • Ivory carving is the carving of animal tooth or tusk, by using sharp cutting tools, either mechanically or manually.
  • Ivory carving is the manual or mechanical carving of either animal tooth or tusk, wherein very fine detail can be achieved, and the surviving works often demonstrate intricate and complicated designs.

• The Fossil Record and the Evolution of the Modern Horse

  • The tooth was sent to the Paris Conservatory, where Georges Cuvier identified it as a browsing equine related to the tapir.
  • In 1833 in Santa Fe, Argentina, he was "filled with astonishment" when he found a horse's tooth in the same stratum as fossils of giant armadillos and wondered if it might have been washed down from a later layer, but concluded this was "not very probable."
  • In 1836, the anatomist Richard Owen confirmed the tooth was from an extinct species, which he subsequently named Equus curvidens.
  • The horse belongs to the order Perissodactyla (odd-toed ungulates), the members of which all share hoofed feet and an odd number of toes on each foot, as well as mobile upper lips and a similar tooth structure.

• Temporomandibular Joint Syndrome (TMJ)

  • Impaired tooth mobility and tooth loss can be caused by destruction of the supporting bone and by heavy forces being placed on teeth.

• Classification of Joints on the Basis of Structure and Function

  • Gomphoses occur between teeth and their sockets; the term refers to the way the tooth fits into the socket like a peg .
  • The tooth is connected to the socket by a connective tissue called the periodontal ligament.

• Vomiting

  • Recurrent vomiting, such as observed in bulimia nervosa, may lead to destruction of the tooth enamel due to the acidity of the vomit .
  • The acidic components of vomit erode tooth enamel over time.
