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 […]
A Multi-Disciplinary Approach in Non-Surgical Re-treatment of Mandibular Right First Molar
Endodontic re-treatment is a usual scenario in daily practice. Though, it can be challenging due to many related factors. Therefore, it requires good assessment of the case through systematic approaches in terms of diagnosis, treatment plan, and the execution of the procedure. A 40 years old male patient presented complaining of discomfort and food impaction […]
Retreatment Series: Episode 2
Root canal retreatment seems to be one of the biggest challenges in the Endodontic therapy, in the retreatment episodes we will review different scenarios with different cases. In Endodontics we are dealing with a lot of challenges such as anatomy, mishaps, instrument separation, etc. but one of the biggest challenges is to deal safely with […]
The management of two mandibular molars with apical inflammatory root resorption
Apical pathology can appear as a straightforward diagnosis, however the tools available for assessment come across different limitations. Histology has highlighted various aspects that can not be yet coherently linked to a clinical situation using imaging investigations (Ricucci, Mannocci & Pitt Ford, 2006). Inflammatory root resorption makes no exception and reveals itself on periapical x-ray […]
Non surgical retreatment of a mandibular first molar with C-shaped canal system
The C-shaped canal, which was first documented in endodontic literature by Cooke and Cox in 1979, is so named for the cross-sectional morphology of the root and root canal. C shaped canals are mostly present in the mandibular second molars, while they are really rare in the first mandibular molars. The cause of forming C shaped canals is the Hertwig’s epithelial […]
Mechanical bypass of separated instruments
Check this case to see how it is possible to bypass separated instruments using FANTA Glider ST in reciprocating motion.
Retreatment episodes, series 1
Root canal retreatment seems to be one of the biggest challenges in the Endodontic therapy, in the retreatment episodes we will review different scenarios with different cases. In Endodontics we are dealing with a lot of challenges such as anatomy, mishaps, instrument separation, etc. but one of the biggest challenges is to deal safely with cases of […]
Perforation repair: step by step
A tooth perforation is a pathologic or iatrogenic communication between the root canal space and the periodontal apparatus. To clinically determine if an endodontically perforated tooth should be extracted or saved, the clinician must first understand the prognosis and treatment. The biologic response of a perforated tooth is inflammatory and can cause a breakdown of […]
The perfect fiber post removal
The fiber post removal is always a challenge and the clinician should be as conservative as possible. Different techniques have been suggested, but two of them are the most common: Ultrasonics and counter-angle burs. The removal of posts from endodontically treated teeth can be a major obstacle in the retreatment of teeth. The goal […]
Retreatment of a maxillary premolar with missed canal
Success of Endodontic therapy depends upon the triad of thorough cleaning and shaping, disinfection & adequate obturation up-to the calculated working length of the root canals. Failure to follow the protocol in any of the above steps can lead to failure of the endodontic treatment. Interpretation of a preoperative radiograph is an important step in […]
Triple MTA apical plug in second lower molar with overextended guttapercha
Mineral trioxide aggregate (MTA) was developed in the 1990s as a root-end filling material and has also been recognized as promising when used to form an apical barrier because of its superior biocompatibility and ability to seal and set in the presence of blood . The use of MTA as an obturation material might ultimately […]
Necrodontics - saving hopeless teeth
Both non-surgical and surgical retreatment procedures are performed when the primary treatment fails and we are trying to preserve the tooth. Usually the next attempt after the primary treatment is non-surgical retreatment and follow up. In some cases when we estimate that non-surgical procedures will not be helpful we can perform surgical retreatment with apicectomy. […]
