What this video covers:

This video provides a general overview of the issue of coronal leakage. It includes these details:

When it comes to root canal, there are two seals that are important.

  • The process of performing endodontic therapy is used to clean out and then fill in and seal off the "nerve" space inside a tooth.
  • Then a second seal, which helps to protect the internal one, is created by the dental restoration that covers over or fills in the "access cavity" through which the root canal therapy was performed.

Coronal leakage involves the recontamination of the tooth's interior.

The tooth's second seal acts as a barrier to contaminates in the mouth that would otherwise seep into it.

In the case of coronal leakage, the restoration has failed in this task. Penetration into the tooth has occurred. As a result, it's root canal system is recontaminated with bacteria and debris.

The type of restoration placed is important in preventing coronal leakage.

Once a tooth's root canal treatment has been completed, the dentist must determine what type of dental restoration can best seal off and protect the tooth's work, as well has how soon this restoration should be placed.

It's possible that in some cases a dental filling might suffice. But in cases where a substantial portion of the tooth must be rebuilt, or the tooth must function under heavy chewing forces, placing a dental crown frequently makes the better choice.
