Internal bleaching of endodontically treated teeth
Teeth discolorations can be extrinsic or intrinsic. The first type is usually caused by food, drinks, smoking and other substances that lead to the deposit of stains on the enamel. The second type are the discolorations that lie within the enamel and/or dentin. Correct diagnosis leads to correct management. Internal bleaching treats only intrinsic discolorations. […]
Three-Year Clinical Follow-Up of Quadrant Restoration After Removal of a Fractured Root Canal Instrument: A Case Report
A substantial portion of clinical dental practice comprises endodontic and restorative procedures. Among these, quadrant rehabilitation frequently presents as a common and complex clinical challenge. During quadrant rehabilitation, the replacement of extensive existing restorations often uncovers structural complications such as cracks and significant loss of tooth structure. In such cases, contemporary indirect restorative techniques offer […]
CBCT-guided management of external cervical resorption in a mandibular premolar
External cervical resorption is often silent, yet treatment planning becomes complex when a subgingival lesion is close to the root canal space. In such cases, the clinical view may underestimate the defect. CBCT provides the information required to define the portal of entry, height, circumferential spread and relationship with the canal.
This case report presents the management of an asymptomatic tooth 44 in a 62-year-old female patient, diagnosed with a Patel 2A external cervical resorption lesion. Treatment combined surgical exposure, removal of fibrovascular resorptive tissue, adhesive repair of the defect and single-visit root canal treatment after identification of a second lingual canal.
Clinical application of Heat-Activated Denco Chameleon Dual Shaper Files in the Endodontic Treatment of a Maxillary Premolar with Symptomatic Irreversible Pulpitis
Successful endodontic treatment relies on effective cleaning and shaping while preserving the original root canal anatomy. Heat-treated nickel-titanium (NiTi) instruments have enhanced the safety and predictability of root canal preparation, particularly in anatomically complex teeth. This clinical report describes the use of the Denco Chameleon Dual Shaper heat-activated rotary file system in the treatment of […]
Retreatment of upper central incisor with over extended GP, a clinical case report
Overextended root canal fillings beyond the apical foramen can lead to persistent symptoms and periapical inflammation. This article discusses a retreatment case involving a maxillary anterior tooth, where the previous gutta-percha obturation was extended beyond the apex. The case was managed using H-file mechanical removal and obturation with bioceramic putty. Radiographic images demonstrate pre- and post-treatment conditions with clear clinical resolution.

Regenerative Endodontic Treatment of an Open Apex with Pulp Necrosis
Single-stage crown lengthening and papilla reconstruction with a sub-epithelial connective tissue graft (SCTG) for subcrestal external cervical resorption (ECR) in the esthetic zone
The joint workshop of the AAP (American Academy of Periodontology) and the EFP (European Federation of Periodontology) reaffirmed that positioning the restorative margin within the fibers of the supracrestal connective tissue attachment represents a significant risk factor for the development of periodontal complications. It is essential to recall that the supracrestal attachment shows considerable dimensional […]
Premolar gemination: a case report
Gemination in lower premolars is a very rare condition. This aspect makes it difficult to treat and it should be approached by an endodontist using a microscope to ensure proper debridement, disinfection and obturation.
Endodontic Retreatment of a Molar with Complex Anatomy
How a good analysis and a efficient protocol can turn and complex case into success.
Conservative Shaping of a Maxillary First Molar with Chameleon Dual Shaper
Modern endodontics increasingly demands instruments that combine efficient cutting with respect for dentine and canal anatomy, especially in complex maxillary molars. Chameleon Dual Shaper files by DENCO were developed to meet this need, offering heat‑activated NiTi metallurgy, enhanced surface hardness, and a dual‑shaper design that supports controlled, conservative canal preparation.
Curvatures, calcifications, long roots: one solution many challenges.
Canal curvatures is a difficult anatomical variation. Calcifications as well. Long roots make treatment complicated. What if all these challenges coincide. We need a simple, feasible and effective protocol to manage such cases. In this article I will try to explain it step by step.
Fanta rising files: Mastering long, ultra-narrow canals with confidence
Introduction Management of long narrow canals remains one of the greatest challenges in modern endodontics. The combination of calcification, reduced canal diameter and limited visibility significantly increases the risk of: • Canal deviation• Ledge formation• Excessive dentine removal• Instrument separation• Failure to reach the original canal anatomy The introduction of CBCT imaging, operating microscopes and […]
