S obturation with hydraulic BC cement for UR5 with deep apical split
Root canal system is a very complex three-dimensional system. Although there are general rules about the anatomy, number of root/s or canal/s for each tooth, but we should expect everything. For that reason, we should have goon understanding, good reading of radiographs, good tools, and experience to deal with different scenarios
Internal Bleaching as a Conservative Alternative to Veneers in Root Canal-Treated Tooth
This article discusses the use of internal bleaching as a conservative and effective esthetic solution for discolored, root canal–treated teeth. It highlights the clinical protocol, indications, and advantages of internal bleaching as an alternative to veneers, preserving natural tooth structure while achieving satisfactory esthetic outcomes.
Retreatment and post-retained restoration in a central incisor
When a tooth has undergone root canal treatment and has lost a large amount of coronal structure, the restorative challenge is not only to replace missing tissue, but to recover function in a biomechanically predictable way. In this context, the use of a fiber-reinforced endodontic post can be particularly advantageous, as it helps to retain […]
Complication of bad endodontic treatment
Endodontic treatment aims to eliminate infection from the root canal system and prevent reinfection of periapical tissues. Inadequate endodontic procedures, such as insufficient canal debridement, improper working length determination, or poor obturation, may result in persistent intracanal infection. This can lead to periapical inflammation and the development of swelling, commonly presenting as a dentoalveolar abscess. Such complications not only cause patient discomfort but may also compromise the prognosis of the affected tooth. This case report highlights a clinical presentation of facial swelling resulting from failed endodontic treatment and discusses its management
Endo-resto management of two molars with failed old large amalgam restoration
Combining precise endodontic treatment with biomimetic restorations preserves tooth structure, restores function, and enhances long-term survival.
Overpost restoration of tooth 25
A 47-year-old female patient presented with a structurally compromised maxillary left second premolar (tooth 25) following completed endodontic treatment. Due to the significant loss of coronal tooth structure, a post-endodontic restoration was indicated to ensure long-term stability and retention of the final restoration. After root canal therapy, the canal was carefully prepared and an Overpost […]
Clinical and Anatomical Challenges in Mandibular Molars: A Comparative Analysis of Two-Canal versus Six-Canal Systems with Apical Pathosis
Mandibular molars exhibit one of the highest degrees of anatomical variability in the human dentition. While the classical configuration involves two or three canals, extreme variations exist, ranging from simplified two-canal systems to highly complex six-canal anatomies. When combined with apical pathosis, these anatomical extremes pose significant diagnostic and therapeutic challenges. Successful endodontic therapy is […]
Retreatment and post endo restoration with Overfibers post
A patient came to my attention complaining about impossibility to chew on the right side of the mouth. A defective restoration was found on the first upper molar, with a distal secondary decay. A decay was also present on the second upper molar. The diagnosis was of apical periodontitis in a previously treated tooth (16) […]
Endodontic Management of a Mandibular Molar with Iatrogenic Perforation, Ledges and Missed Canals
Successful endodontic therapy begins with a properly designed access cavity, which is the foundation for locating, cleaning, and shaping the root canal system. Inadequate or misdirected access can lead to missed canals, ledge formation, and iatrogenic perforations, severely affecting the outcome of treatment [1]. Understanding the pulp chamber floor anatomy—including color changes, developmental grooves, and […]
When Anatomy Fights Back: retreatment of a C-shaped mandibular second molar
Re-treatment of C-shaped mandibular molars demands 3D cleaning and sealing beyond files; a stepwise strategy improves predictability.
Biological Approach to Revitalization in Immature Permanent Teeth: No-instrumentation Technique
Treatment for immature, necrotic permanent teeth is showing a paradigm shift in moving from a non-biological, barrier-creating approach (apexification) to a biological, tissue-regeneration approach. Conventional root canal treatment has a high long-term success rate (over 86%) for mature permanent teeth with irreversible pulpitis, pulp necrosis, or pulp exposure. However, immature permanent teeth present more significant […]
Transforming a Non-Visible Separated File into a Visible Fragment: A Conservative Retrieval Approach
Instrument separation is a well-recognized complication in endodontic practice, and its management can significantly influence the long-term prognosis of the tooth. While some fractured instruments are readily visible and accessible, others remain hidden, particularly when located beyond canal curvatures. Non-visible fragments pose a greater challenge, as blind retrieval attempts risk excessive dentin removal, perforation, or structural weakening of the root.
