In this article i am highlighting the way i’ve dealt with this syptomatic lower 1st molar from the Retreatment to the final Restoration.
Lack of knowledge in the endodontic field may lead to some errors during the treatment if we are not having the right techniques combined with the right tools and it is so important to to save the tooth to the last chapter by providing a good, functional and durable restoration.

The first line of the treatment was to remove any filling inside the canal, followed by the placement of an intra - canal medication to raise the pH inside, since the root canal was still wet.

The patient left for 3 months and didn’t show up. When she came back and we took an X-ray , we found that a lesion healed after long term placement of the medication.

Both mesial and distal canals were filled with squirting technique

IDS, “IMMEDIATE DENTIN SEALING’ was done immediately after the obturation in conjunction with the overlay preparation.

Conclusions
The clinician must have enough knowledge about the root canal anatomy, techniques and to know how to deal with errors if happened as well to provide the patient with a good, sealed long term restoration.
