Journal: Journal of endodontics


The aim of this work was to characterize the by-products formed in the associations between the most commonly used irrigants in endodontic practice through electrospray ionization quadrupole time-of-flight mass spectrometry analyses.

Concepts: Mass spectrometry


Profound pulpal anesthesia in posterior mandibular teeth with irreversible pulpitis usually requires administering an inferior alveolar nerve block (IANB) plus other supplemental injections. The purpose of this prospective, randomized, double-blind study was to compare the anesthetic success rate of buccal infiltration injections of articaine and lidocaine when supplemented with an IANB.

Concepts: Cranial nerves, Mandibular nerve, Local anesthetic, Inferior alveolar nerve, Mandibular canal


The purpose of this study was to examine the effect of mineral trioxide aggregate (MTA) on pluripotent-mesenchymal cell differentiation.

Concepts: DNA, Magnesium


The combined influence of cyclic fatigue and torsional stress on rotary nickel-titanium instruments has been little investigated. The aim of this study was to determine possible differences in the fracture point of rotary nickel-titanium instruments depending on the application of cyclic fatigue only (CO) or in combination with torsional stress (CT).

Concepts: Fracture mechanics, Elasticity, Mechanics, Polar moment of inertia


An immature mandibular right first molar (#30) with apical periodontitis of a 9-year-old boy was treated with a revascularization/revitalization procedure using either a mixture of platelet-rich plasma (PRP) and a blood clot or a blood clot alone on the same tooth.

Concepts: Protein, Myocardial infarction, Thrombosis, Coagulation, Shock, Hematology, Thrombus, Teeth


The purpose of this study was to describe a series of unicystic ameloblastomas (UAs) that presented clinical and radiographic similarities to apical periodontitis in order to call the attention of clinicians to the fact that several different diseases are able to mimic endodontic periapical lesions.

Concepts: Disease, Evaluation methods, Difference


The purpose of this study was to determine the shaping ability of 3 nickel-titanium (NiTi) endodontic file systems by measuring canal transportation.

Concepts: River, Transport, Canal, File system, Canal+


The purpose of this study was to determine and compare the times needed to dislodge prefabricated titanium posts of different luting lengths with various cements.

Concepts: International System of Units, Height, Newspaper, SI base unit, Broadsheet, Times Roman, News Corporation, Rupert Murdoch


Autotransplantation of immature teeth can be an option for premature tooth loss in young patients as an alternative to immediately replacing teeth with fixed or implant-supported prostheses. The present case series reports 4 successful autotransplantation cases using computer-aided rapid prototyping (CARP) models with immature third molars.

Concepts: Teeth


In this report, we discuss the case of a 39-year-old woman presenting with a case of chronic maxillary sinusitis.

Concepts: Sinusitis, Maxillary sinus
