Selective root canal re-treatment is a novel approach which aim at treating the selected root/s showing apical pathology.
Thanks to the use of CBCT it is now possible to evaluate with high accuracy the status of a root filled tooth and plan the re-treatment strategy accordingly.
This approach has clear advantages in terms of preservation of tooth structure, reduction of iatrogenic errors and reduced operating time and costs.

The primary goal of root canal shaping is to create a continuously tapered, funnel-shaped canal while preserving the original anatomy. This is significantly harder to achieve in a curved canal […]

Whenever root canal anatomy is discussed, variability is the rule!!
This requires careful attention of the clinician to anticipate such variation

The maxillary first molar is among the most anatomically complex teeth in the human dentition. Its intricate root canal system, particularly the variability of the mesiobuccal root, poses significant challenges for endodontic treatment. This review consolidates current literature on the external and internal morphology of the maxillary first molar, emphasizing the prevalence of additional canals, the clinical relevance of advanced diagnostic tools such as cone-beam computed tomography (CBCT) and micro-computed tomography (micro-CT), and the implications for endodontic therapy. Special attention is given to the second mesiobuccal canal (MB2), its detection, and its role in endodontic success.

Complex anatomies in premolars pose significant challenges in endodontic treatment. Their relatively small size coupled with variations such as additional canals require specialized techniques and instruments. Effective management of these complexities demands a thorough understanding of canal anatomy and mastery of advanced instrumentation and obturation techniques. This article covers strategies for navigating one such complex anatomy, ensuring successful treatment outcome and minimizing complications.

Endodontics, the branch of dentistry that deals with the treatment of the dental pulp and tissues surrounding the roots of a tooth, has advanced significantly in recent years. A critical aspect of this field is the pre-endodontic build-up, a procedure often necessary to ensure the success of root canal treatment. While it might seem like a routine step, its importance cannot be overstated. This article delves into the significance of pre-endodontic build-up, its benefits, and why it should be an integral part of every endodontic procedure.

Root perforation is a complication of Endodontic treatment characterized by the communication between the root canal space with the periodontal tissues. These accidents usually occur due to iatrogenic causes including lack of knowledge of dental anatomy, wrong endodontic access, calcification of the coronary and cervical thirds, failure in radiographic analysis. Among the factors that affect root perforation prognosis are the location (cervical, middle and apical thirds), the extent, presence or absence of periodontal pockets, the time between perforation and treatment, biological compatibility and sealing ability of the filling material.

We often need to retreat teeth where the initial treatment was short from the radiographic terminus of the root. Many times, when we remove the existing filling our files cannot […]

Unusual anatomy of a maxillary first molar with two palatal canals

The failure of root canal treatment is a problem encountered by every dentist. A large number of studies have shown that teeth may continue to have previous periapical lesions or even develop new periapical lesions after root canal treatment. The reasons for root canal treatment failure, the site to be debreached, the method to be repaired, and the communication with the patient are all very important factors in retreatment.

INSTRUMENT FRACTURE IS A COMMON COMPLICATION IN ENDODONTICS THAT WE MUST BE PREPARED TO SOLVE IN A PREDICTABLE WAY. IN THIS CASE WE SHOW HOW TO SUCCESSFULLY RESOLVE THIS COMPLEX SITUATION

Matching the color of dental crowns to discolored tooth abutment is a tough challenge in modern dentistry. When a tooth abutment is discolored—due to staining, injury, or previous treatments—it can be hard to make a crown that looks natural and blends well with the surrounding teeth.
The difficulty comes from several factors: the original color of the tooth, the type of discoloration, and the materials used for the crown. Although new materials and techniques have made it easier to match colors, getting a perfect match is still not always possible. This can affect the overall look of the dental work.
