Old root canal fillings with broken files
The patient presented with old root canal fillings (alio loco) on tooth 26. On the overview X-ray and on the tooth film, the broken metal files can be seen as lighter parts of the root canal fillings. After the files had been filed in the direction of the root tip, the canals could no longer be filled by the pre-treatment person. Thus the root canal fillings are clearly too short.
Detail of the panoramic tomographic image:
We repeated the root canal treatment and were able to carry out the preparation and filling up to the root tip within the canals past the file fragments. The broken file pieces are integrated as part of the root canal filling were left.
Unfortunately, the tooth film of the new fillings of the canal system, the buccal and palatal canals are somewhat superimposed:
In the next session, the tooth will definitely be restored adhesively with a ceramic partial crown made of e.max Press. The prognosis is now more favourable.
Revision of root canal treatment on tooth 26
The root canal treatment on tooth 26 had been performed (alio loco) without rubber dam. The tooth was insufficiently treated with a plastic build-up for a longer period of time. Before the final restoration with a partial ceramic crown, we suggested a revision of the root canal treatment. During the revision, a second, previously untreated mesiobuccal canal (mb2) was visible.

Revision of a root canal treatment on tooth 16
The patient presented as a new admission with pain at tooth 16. The X-ray and the tooth film show too short root canal fillings and a discreet apical osteolysis (inflammatory bone resolution).
We carried out an endorevision under aseptic conditions with rubber dam and the channels were prepared, cleaned and completely filled. The second mesio-buccal channel (mb2) was processed by us for the first time.
The prognosis of the tooth is now more favourable.
Root canal treatment of the day on tooth 25
The patient presented with an incomplete root canal filling on tooth 25:
We carried out a root canal treatment with rubber dam under aseptic conditions. Both canals are completely filled until apical constriction.
In the next session, the tooth is restored with a partial ceramic crown (e.max Press). The prognosis is now more favourable.
Endorevision of three teeth
As the patient has a longer journey, the root canal treatments on three teeth were revised in one session.
Tooth 37 showed too short root canal fillings at the mesile root and inflammatory bone dissolution at both root tips:
We have revised the treatment and cleaned, disinfected and completely filled all channels:
Tooth 18 showed a broken instrument apically in the mesiobuccal root. The root canal fillings are insufficient at tooth 16:
Here is the control X-ray after the endorevision on tooth 18. The broken instrument could not be removed, but was integrated sterile into the root canal filling. The prognosis of the tooth is now favourable.
Here the X-ray of root canal fillings after the revision of the endodontic treatment on tooth 16:
The x-ray shows the two mesiobuccal root canal fillings mb1 and mb2. In addition to mb1, mb2, db and p, a “fifth” canal filling is visible. This is the fistula duct after buccal that was closed with a sealer (AH Plus).
