The management of separated endodontic instruments using a customized syringe and loop technique: A case series

Endodontology, 2023
The separation of the nickel-titanium (NiTi) rotary files is seen occasionally due to improper use and lack of technique, which results in improper cleaning and shaping of the root canals, compromising the treatment outcome.

Dental Operating Microscope in Endodontics-A Review

IOSR Journal of Dental and Medical Sciences, 2013
Traditional endodontics has been based on feel not sight. Together with radiographs and electronic apex locators this blind approach has produced surprising success. There is, however, a significant failure rate, especially in long -term. Magnification helps the user not only to see more, but to see wel l.

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

Advanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Accuracy of Dental Operating Microscope versus CBCT in Detecting number of Root Canals for Maxillary Second Molars indicated for Retreatment

Journal of Fundamental and Clinical Research
Introduction: A key failure of root canal treatment is the practitioner's inability to detect all the canals during treatment. Root canal detection aids like Cone Beam Computer Tomography (CBCT) scans and Dental Operating Microscopes (DOM) are valuable ...

Clinical diagnostic approach in the treatment of chronic periodontitis in mandibular molars: Clinical cases

Кубанский научный медицинский вестник, 2023
Background. Inflammatory process in periapical tissues causes tooth extraction in more than 50% of cases. The development of chronic apical periodontitis can be triggered by an intracanal infection in undetected/missed root canal of the mandibular molars.

Accuracy of Dental Operating Microscope in Detecting Number of Root Canals in Human Mandibular First Molars Obturated and Indicated for Retreatment: Diagnostic Accuracy Experimental Study

, 2023
Background: Failure to disinfect and to locate all canals is a major reason for root canal primary and secondary failures, which may lead to periapical periodontitis. Cone beam computed tomography (CBCT) is considered the gold standard in canal detection
