Effect of Pulpotomy Procedures With Mineral Trioxide Aggregate and Dexamethasone on Post-endodontic Pain in Patients with Irreversible Pulpitis: A Randomized Clinical Trial.

Objective: Endodontic post-treatment pain continues to be one of the main problems encountered by dental professionals. Therefore, pain control during and after endodontic treatment is one of the most important issues in endodontics. The purpose of this clinical trial was to compare postoperative pain relief achieved with dexamethasone (DEX) and mineral trioxide aggregate (MTA) used as pulp coverage after pulpotomy in human molars with irreversible pulpitis.

Clinical, Radiographic, and Histologic Evaluation of Regional Odontodysplasia: a Case Report with 5-year Follow-up.

Regional odontodysplasia is a developmental anomaly that affects the primary and permanent dentitions. This disorder is generally localized in only one arch and its etiology is still unknown. Clinically, the affected teeth have an abnormal morphology and are typically discolored.

The effects of a dairy probiotic product, espar, on salivary calcium and mutans streptococci.

Background and aims. Espar is a dairy product of probiotic nature that contains useful bacteria and high calcium content. The aim of this study was to analyze effects of daily consumption of Espar on the number of salivary mutans streptococci and the level of calcium content in a population of 15 to 17 year-old female students.

Success of ultrasonic technique in removing fractured rotary nickel-titanium endodontic instruments from root canals and its effect on the required force for root fracture.

Introduction: Fracture of rotary nickel-titanium files is a real concern among endodontists; it affects the long-term prognosis of treatment. Ultrasound is a favorable technique for removing broken files, although it may result in some complications. The aim of this study was to determine the success rate of ultrasonic technique in removing file fragments and to evaluate its influence on the force required to fracture a tooth root.

Effect of MRI on the mechanical properties of stainless steel orthodontic wires.

Aim: To assess whether the forces created by the magnetic resonance imaging (MRI) field cause a deflection of orthodontic stainless steel archwires or a change of their mechanical properties.

Methods: Sixty stainless steel 0.016-inch archwires were divided into three groups of 20 wires each.
