This article will discuss the non surgical endodontic retreatment of a mandibular first molar with mid-mesial canal.   Endodontic retreatment is a procedure performed on a tooth that have a previous attempt of definitive treatment resulting in a condition that […]

Root perforation is a challenging situation when the root canal has a pathological communication with periradicular area. Perforations can occur as an iatrogenic accident during a root canal instrumentation and is the second cause of failed endodontic treatment. In some cases complications may lead even to an extraction. Thus, successful treatment of a root perforation […]

There have been many recent technical advances in modern endodontics that have the potential to affect treatment outcomes. The purpose of this article is to determine the success of nonsurgical root canal retreatment in molars using contemporary endodontic techniques.

From a medico-legal aspect, extrusion of root canal filling might be considered malpractice if there is excessive extrusion of material combined with incomplete obturation of the canal leading to failure of the root canal treatment.(1) Acute Apical Abscess AAA is the most common form of dental infections and is caused by the infected root canal […]

Non-surgical root canal re-treatment is one of the most dental procedures that practitioners face in routine daily work. Though, it remains one of the most challenging procedures, as we are dealing with root canal complexities, different root filling materials, and most importantly, infection.

The use of CBCT at the diagnostic and treatment planning stage allows to detect presence of refractory endodontic pathology root by root in multicoated teeth. Teeth affected by pathology in one root only due to the presence of missed anatomy cannot be re-treated surgically and a selective orthograde re-rct approach can be opted for. The […]

In retreatments, one of real endodontic challenges comes when disassembly is complete and what remains is a root canal system that has been perforated.  What is the critical thinking required to solve such impediment to success? In this article, I am describing the management of a root perforation using absorbable collagen membrane as an internal […]

As Endodontists our daily work is an adrenaline fuel because we face new challenges on a daily basis and each case requires a strategy to fix it. Strategy before any retreatment consists of reading very carefully the preoperative X-Ray, in order to explain to the patient what is the problem, prognosis ,number of visits, possibility […]

The ledge, which is a deviation from the original canal curvature without communication with the periodontal ligament, is created when the working length can no longer be negotiated, and the original pathway of the canal has been lost. Ledge formation might lead to incomplete instrumentation and shaping, inadequate disinfection, and inadequate three-dimensional obturation of the root canal […]

Nowadays the number of retreatment cases are increasing in front of primary treatments. That’s why we need some innovative tools to help us achieving our rationale in non-surgical retreatments. In this article, I will describe various aspects of the New Retreaty instruments designed by styleitaliano endodontics team and manufactured by Perfect Endo. Similar to primary […]

In this article we are introducing the RE-TREATY files for the retreatment of Maxillary Molar and we will show how the system combines the function of Cutting Efficiency & Flexibility to facilitate the Retreatment step in a conservative way.

In our daily practice, we face a lot of difficulties in root canal treatment and re-treatment. Some of these difficulties may be due to the case itself, and others may happen during the procedure. Key factors to overcome such situations are identifying these difficulties and knowing how to deal with them.
