The vicious cycle of errors in retreatment cases

A simple step by step technique of separated instrument removal, gaining patency and perforation repair.

Apical control management with bioceramic sealer

One of the most critical steps in endodontic treatment is the filling of the root canal system. The goal of 3D obturation is to fill the entire root canal system with a biocompatible material to prevent the entry of bacteria and other irritants that can cause infection or inflammation (Camilleri J. 2015). Many techniques and […]

Ledge detection and bypass with Explora after broken file removal

The success of Endodontic retreatment is multifactorial and will depend on the degree of root canal morphology alteration. Irreversible iatrogenic errors such as large perforations or canal transportation will decrease drastically the good prognosis of the treatment. In cases where it is possible to regain the original anatomy and shape, clean and fill the entire […]

Management of a long canine using ExtEndo

In cases of long roots, the filling procedure can often be difficult especially for the cone fit step, in which gutta-percha cones can be shorter than the working length.

Thermafil Retreatment of a right upper first molar

The Thermafil Obturation technique was first introduced by Dr. W.B. Johnson in an article published in the Journal of Endodontics in 1978 as a simple method for the delivery of thermo-plasticized gutta-percha (GP) to the prepared root canal space. Many studies proved that it was an efficient, easy and reproducible obturation technique with a high […]

Treatment of a C shaped canal of a mandibular second molar

Mandibular second molars are known to have a complex root canal anatomy with anastomosis, resulting in some difficulties during root canal treatment, especially for the complete debridement of organic tissues and bacteria during the shaping and cleaning process and the possibility of insuring a good 3-dimensional seal during obturation. The prevalence of such anatomy is […]

Removal of an Anatomic Post and Core A Case Report

Different types pf posts can be placed during restorative procedures; prefabricated ones such as the screw posts, the paraposts or more recently the ceramic post and fiber posts, or the anatomical post commonly called cast post and core. In cases of non surgical retreatment The removal of a post can be challenging depending on the […]

The removal of filling material during retreatments

The prognosis of initial endodontic treatment is mostly favorable . Nevertheless, failure can occur due to the persistence of bacteria following initial treatment or due to inadequate disinfection, shaping and obturation of the root canal system. The possibility of a secondary infection is also not to be excluded, especially when a defective coronary reconstruction leads […]
