root canal

1. A pulp-filled channel in a root of a tooth.
2. A treatment in which diseased tissue from this part of the tooth is removed and the resulting cavity is filled with an inert material.

root canal

Dentistry A popular term for the complete removal of a tooth's pulp from the root canal and filling it with an inert material; RCs are performed when the decay is too deep for amalgam to provide adequate permanent therapy

root canal

The pulp cavity in the root of a tooth.

Root canal

The space within a tooth that runs from the pulp chamber to the tip of the root.

Patient discussion about root canal

Q. How much does a root canal hurt? I have to get a root canal for my bottom tooth. I was wondering how much they hurt. And do you have any suggestions that help distract from the pain? Thanks.

A. i did one about two years ago- even the injection wasn't too bad! didn't feel a thing. but after the anesthesia worn off it hurt. but then the dentist told me to take Advil or any other NSAID and it helped.

In epidemiological studies, different methods had been used for categorizing the quality of root canal fillings. Some studies used only length7,8 while others measured length and density9,10 and in addition to these, taper of the root canal fillings was also taken into consideration.11-13
An evaluation of microbial leakage in roots filled with a thermoplastic synthetic polymer-based root canal filling material (Resilon).
In the present study, we did not use chloroform because of these reported disadvantages, but we used Guttasolv in two subgroups (A1 and B1) because gutta-percha was used for the root canal filling core material in all groups and Guttasolv is intended to soften gutta-percha material.
In this study two different canal preparation techniques (manual and rotary) were compared on the basis of technical quality of root canal filling. Technical quality of root canal filling was evaluated on the basis of three characteristics including length, density and taper of root canal filling.
A root canal filling which looks badly condensed on the radiograph may contain many "cul de sac" type voids and no leakage.
To assess the technical quality of root canal fillings, three criteria were evaluated as follows:
On radiograph no space should be visible beyond the end point of root canal filling. There should be no void or space between the root canal filling and the wall of the root canal.
Evaluation of the apical seal produced by a hybrid root canal filling method, combining lateral condensation and thermatic compaction.
Therefore, the sealing quality of a root canal filling depends much on the sealing ability of the sealer used.5 Many different techniques have been introduced in order to increase the quality of apical seal of the root canal.6 However lateral conden- sation technique is the most widely used technique for obturation of the root canals.
Resilon core material is a thermoplastic synthetic polymer-based root canal filling material and Epiphany SE is a self etch resin based sealer that eliminates the priming step.
Radiographic technical quality of root canal Fillings performed by house surgeons in the Islamic interna- tional dental college: a pilot study.
A grading system suggested by Somma et al was used to score the remaining root canal filling material in the coronal, middle and apical third of each root half.
