COMPARATIVE EVALUATION OF POSTOPERATIVE PAIN AFTER SINGLE VISIT ENDODONTIC TREATMENT USING PROTAPER UNIVERSAL AND PROTAPER NEXT ROTARY FILE SYSTEMS: A RANDOMIZED CLINICAL TRIAL

Introduction: Root canal preparation may cause inadvertent apical extrusion of debris causing postoperative pain.This debris varies with the instrumentation technique and design characteristics.One of the major revolutions in the design of the instruments is the introduction of files with an offset center of mass or/and rotation, which causes asymm

High-speed rotors on gas foil bearings (GFBs) are applications of increasing interest due to their potential to increase the power-toweight ratio in machines and also formulate oil-free design solutions.The gas lubrication principles render lower (compared to oil) power loss and increase the threshold speed of instability in rotating systems.Howeve

Abstract Background Repeated rehearsal is one method by which verbal material may be transferred from short- to long-term memory.We hypothesised that extended engagement of memory structures through prolonged rehearsal would result in enhanced efficacy of recall and also of brain structures implicated in new learning.Twenty-four normal participants

From the end of the 1990s, several studies based on imaging evidenced the participation of reward mechanisms in the hearing of tonal music.Tonal music is constructed from a set of discrete elements (musical notes) organized Magnets in time according to mathematical reasons and well-defined structural relationships, thus enabling, through the repeti

We compute the four-point amplitude with external adjoint particles in N=2 SCQCD at two loops using N=1 Cot Pocket superspace Feynman diagrams, extending the results of arXiv:1406.7283.We consider the diagrammatic difference with the corresponding process of N=4 SYM finding a non-vanishing result, which is a non-trivial function of the kinematic va
