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.

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+

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

Dental pulp inflammation and repair are closely related. Osteocalcin (OCN), a glycoprotein present in dentin matrix, is expressed by odontoblasts. Although OCN is considered a reparative molecule inside the dental pulp, it is not clear if it is involved in pulpal inflammation. The objective of this study was to localize OCN in reversible and irreversible pulpitis and to describe its possible function in inflammation.
