The unique morphology of dilacerated and S-shaped root canals often pose utmost challenges in their endodontic management. Common causes of failures in such cases are primarily related to procedural errors such as ledges, fractured instruments, canal blockages, zip and elbow creations. Knowledge of dental anatomy and its variations is essential for the success of endodontic treatment. A clinici...

A sound knowledge of the normal tooth morphology and its numerous variations is essential to the success of endodontic therapy. While extra canals and lateral canals are routinely encountered and documented, there also exists the rare possibility of a fewer number of canals than normal. Early detection of such an occurrence is critical to the prevention of iatrogenic errors during endodontic tr...

Preservation of a patient’s natural dentition remains an important outcome in securing oral health. Dentists and patients are facing a perplexity between saving a compromised tooth through endodontic treatment, retreatment or extraction. Though success rates of endodontic initial treatment have been improving over the years, persistence of periapical disease is far from being a rare condition. ...

Clinicians are frequently facing the dilemma of weather to perform endodontic treatment in order to retain a necrotic tooth or to extract and replace it with a dental implant. According to recent reviews, the long-term survival rates of sound or even compromised teeth surpassed those of oral implants [1, 2]. During the last decade, the endodontic therapy improved continuously due to modern equi...

The pathways for the spread of bacteria between pulpal and periodontal tissues have been discussed with controversy. Treatment and prognosis of endodontic–periodontal diseases vary and depend on the cause and the correct diagnosis of each specific condition. One treatment modality in such cases involves separation of two roots in the furcation area with selected removal of one root. This decisi...

The purpose of this study was to evaluate clinical outcomes with the use of Resilon root filling in private endodontic practice. This study compared immediate post-operative (IPO) radiographs with at least one year posttreatment, follow up (F) radiographs from 70 randomly selected private practice primary endodontic cases, treated according to a non-standardized protocol but root-filled with Re...

Background: Knowledge of variations in dental anatomy and canal morphology plays a key role in the success of endodontic therapy. Case presentation: This report presents a patient who had unusual tooth morphology, including the bilateral existence of 11 maxillary and mandibular first, second and third molars with a single root and a single canal. The patient was diagnosed using cone-beam comput...

When a method of intracoronal reinforcement is selected, many factors must be weighed. The hazards include (1) the induced stresses and the risk of fracture during placement of the dowel, (2) the probability of root perforation during post space preparation, (3) the wedging action of tapered dowels, and (4) the incidence of fracture with self-threading pins in devitalized teeth. The amount of t...

This case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. In all represented cases, calcium enriched mixture (CEM) cement is used for root-end filling. This case series demonstrates twenty cases of IR and extraoral root-end resection and filling with CEM cement. All the selected teeth had a failed endodontic tr...

During patient treatment, the clinician needs to consider the operator needs, the restoration needs, and the tooth needs. This article discusses molar access and failures of endodontically treated teeth that occur not because of chronic or acute apical lesions but because of structural compromises to the teeth that ultimately render them useless. The authors believe that the current models of e...
