ROOT CANAL RETREATMENT

Repeat endodontic treatment is the dental procedure performed in the office by an endodontist in order to heal an already endodontically treated tooth in the mouth.

Many teeth that have been denervated in the past show insufficient healing and consequently, pain or swelling.

The main cause is the existence of microbes in the root canals of the tooth, which have either not been removed in the first place in the initial denervation, or have reappeared long after the denervation.

In the first case, the existence of microbes may be due to:

  1. in that endodontic treatment may be incomplete due to anatomical difficulties of the tooth, which were not treated in the initial denervation,
  2. in the delay in placement of the final restoration (e.g. case),
  3. in the fact that the final restoration does not hermetically close the tooth to prevent saliva and bacteria from entering the root canals.

In the second case, the existence of microbes may be due to:

  1. In the second case, the existence of microbes may be due to:
  2. in the appearance of new caries under the seal.

With the magnification of the optical microscope and the use of high-tech tools and biomaterials, the endodontist can provide high success rates for endodontically treated teeth, similar to that of natural teeth.

Frequently asked questions

It is a procedure performed by an endodontist to restore a tooth that has already undergone denervation, when the initial treatment has failed to completely eliminate the germs or new complications have appeared.

Continued pain, swelling, or radiographic findings indicating failure to heal (eg, apical cyst).

 

  • Anatomical difficulties that were not addressed in the first treatment.
  • Delayed or incomplete placement of the final restoration (eg, case).
  • Incomplete removal of microbes from the root canals.

 

  • Loss of prosthetic restoration (case or seal).
  • New caries under the existing restoration.

The optical microscope allows better visibility of the root canals, identifying difficulties or poorly treated areas, while increasing the accuracy of the treatment

With the use of modern techniques, tools, and biomaterials, the success rates of repetition are comparable to those of natural teeth.
