INTRODUCTION The purpose of this study was to evaluate cyclic fatigue fracture resistance of engine-driven nickel-titanium (K3XF) instruments under reciprocating movement in various angles. METHODS Fifty K3XF size 40 taper 0.06 nickel-titanium instruments were divided randomly into 5 groups of 10 each. All instruments were subjected to cyclic fatigue(More)
INTRODUCTION The goal of the present study was to test the fatigue resistance of nickel-titanium rotary files in a double curvature (S-shaped) artificial root canal and to compare those results with single curvature artificial root canals. METHODS Two nickel-titanium endodontic instruments consisting of identical instrument sizes (constant .06 taper and(More)
AIM Arteriovenous malformations (AVMs) with a high flow of the head and neck are quite rare compared to their low-flow counterparts, but when they do occur they are often accompanied by massive bleeding or present with significant esthetic defects. The treatment of these high-flow vascular anomalies is often highly risky. The multidisciplinary approach(More)
BACKGROUND In recent years Europe has received an increasing influx of migrants, many of whom risked their lives crossing the Mediterranean Sea. In October 2013, Italy launched a search and rescue operation at sea in response to migrant deaths during the sea crossing. In August 2014, Médecins sans Frontières and the local Ministry of Health established an(More)
BACKGROUND, AIM, AND SCOPE Phenols are the most common pollutants in industrial wastewaters (particularly from oil refineries, resin manufacture, and coal processing). In the last two decades, it has become common knowledge that they can be effectively destroyed by nonconventional techniques such as power ultrasound (US) and/or microwave (MW) irradiation.(More)
A new manufacturing process involving twisting of a ground blank combined with heat treatment has been recently developed to produce nickel-titanium rotary files for root canal preparation. The aim of this study was to compare torsional resistance of prototype instruments produced using the new manufacturing method versus traditional nickel-titanium(More)
AIM This pilot study evaluated patients' experience of oral surgical and prosthetic procedures as well as their opinions regarding function, aesthetics, comfort, and satisfaction with treatment outcomes. MATERIALS AND METHODS Forty-nine subjects treated with oral implants completed questionnaires comprising 44 questions. Three questionnaires were used(More)
Hanau's laws and the so-called articulation quintet have contributed greatly to the evolution of the prosthetic dentistry and have been further elaborated by various authors. The main aim of this study was to establish the stability of prosthetic plates by attaining balanced occlusion. Several authors have addressed the problem of removable and fixed(More)
The effect on halogenated aromatics of solid, non-toxic oxidants such as sodium percarbonate and the urea/hydrogen peroxide complex (Fenton-like reagents) was investigated. A microwaves-assisted, solvent-free method for soil decontamination is presented. It marks a considerable advance in the search of more efficient, environment-friendly procedures for the(More)
