The use of solvents helps removing the filling material form the canals, however it may as well slow down the retreatment process.
A case report

Root canal retreatments have always been the elefant in the room. The preoperative X-ray may or may not predict future difficulties, thus the clinician has to stay constantly alert for any unplanned situations that have to be managed. Nonclinical curvatures, separated files, ledges, perforations and much more circumstances can be completely camouflaged inside a common […]

In this article we are going to share management of a lower first molar with a non-surgical re-treatment (NSRT) approach.

Retreatment isn't about creating longer or better looking white lines , it's about understanding causes of failure and how to overcome them, Usually the cause of failure is due to not abiding to the following parameters such as proper diagnosis including preoperative periapical radigraphs, isolation of the field, full chemo-mechanical preparation of the canals and […]

Retreatments in endodontics are always a challenge. Nowadays above all for Endodontist retreatments are a daily routine. Each case is different and it’s important have the right tools and the right strategy to be able to face them. In this article I am describing all the phases step by step to retreat a difficult case […]

The American Association of Endodontists (AAE) Glossary of Endodontic Terms defines perforations as mechanical or pathological communications between the root canal system and the external tooth surface (2003). Root perforations are severe complications and are associated with compromised endodontic treatment outcomes, especially when bacterial infection is allowed to establish. Perforations may occur due to pathological […]

There is a great trend of interest in minimally invasive treatments in endodontics. Is it possible to apply the same concept in Retreatments, where the previous therapy has failed?Can we change in some way our mindset?Is it possible to use as much as possible just a sequence like ReTreaty kit instead of many different files?

Retreatment is considered a difficult manipulation that requires the knowledge, experience and technical equipment from the doctor. Resorcinol-formaldehyde therapy is no longer used as a medical material, but since the 1960s it was widely used in different countries, which increases the chance of such a patient getting into your daily practice. The article discusses the clinical scenarios developed because of the use of the mentioned material and ways to deal with it.

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 […]

One of the most common causes of failure in endodontics is missing canals.
The middle canal in lower molars is not an exception and has been studied by numerous authors in the literature.
Its prevalence ranges from 0,28% to 53,8% and it’s specially presents in the mesial root.
Using different X-ray angulations or with the help of CBCT we can confirm its existence.
Understanding the anatomy of the teeth is a key factor for the success of our treatment.
In this case we are treating a previously treated lower molar with some hidden anatomy.

In this article, we are going to explain the Braiding Technique, a predictable way to remove materials from inside root canals.  For this technique, we will use Hedstroem files, and is especially indicated to remove plastic carriers during retreatments. We will see the technical procedure and some clinical cases with video, picture and X-ray. As […]

Perforation (often of the floor) is one of the problem to solve that can happen when we start to do a retreatment. There is a lot of confusion and question when we spoke about the management and the phases to solve this type of problem. In this article I am describing all the phases step […]
