English: A diagram demonstrating endodontic therapy (colloquially known as a root canal) on unhealthy or injured tooth: first drilling and cleaning, then filing with an endofile, and finally adding the rubber filling and crown.
A root canal is the naturally occurring anatomic space within the root of a tooth. It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
The health of the dental pulp can be established by a variety of diagnostic aids which test either the blood supply to a tooth (Vitality Test) or the sensory response of the nerves within the root canal to specific stimuli (Sensitivity Test). Although less accurate, sensitivity tests, such as Electric Pulp Tests or Thermal Tests, are more ...
Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
this root canal illustration is scheduled for next friday's PotD JelloCube27's Trace Reason A nice diagram but it's not FP-worthy. Maybe if it was SVG I'd be wowed by it enough to hold off on the delist for a couple years :) Nominator froth T C. Delist — froth T C 01:08, 5 January 2007 (UTC)
The fibrous-root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root, with smaller roots branching off. The letters indicate where the root systems begin. A taproot is a large, central, and dominant root from which other roots sprout
The post on the left is a tapered post, the one on the right is a parallel post. In post and core fabrication, it is desirable that the post descend at least two-thirds of the length of root canal (or not less than the height of the crown) in order to provide sufficient retention.
In dental anatomy, the cementoenamel junction (CEJ) is the location where the enamel, which covers the anatomical crown of a tooth, and the cementum, which covers the anatomical root of a tooth, meet.
