Definition of root canal

root canalnoun

ống tủy

/ˈruːt kənæl//ˈruːt kənæl/

The term "root canal" refers to the natural hollow chamber within the tooth's root that is filled with delicate pulp tissue. The pulp is made up of blood vessels, nerves, and connective tissue that help form and nourish the tooth during its development. However, once the tooth is fully matured, these structures are no longer necessary and can become infected or inflamed due to decay, injury, or other factors. In such cases, a procedure called root canal therapy is performed to remove the pulp and clean the root canal system, replacing it with a filling material to prevent further infection and restore the tooth's functionality. The origins of the term "root canal" can be traced back to its anatomical context, as the canal follows the path of the root's inner layer, or dentin, which helps anchor the tooth in the jawbone. Over time, the phrase "root canal" has become commonly used in dental terminology to refer specifically to this type of restorative treatment.

Example:
  • I've had two root canals so far.

    Cho đến nay tôi đã điều trị tủy hai lần.

  • I'd rather have root canal than sit through another boring meeting.

    Tôi thà đi chữa tủy còn hơn phải ngồi dự một cuộc họp nhàm chán nữa.
