Evaluation by Scanning Electron Microscopy and Energy Dispersive X‐Ray Spectroscopy of the Effects of Root Canal Instrumentation on the Radicular Dentine

Microscopy Research and Technique, Volume 88, Issue 5, Page 1555-1565, May 2025.
Free dentinal tubules in the middle 1/3 of the root canal. ABSTRACT One area of technological advancement has been the shift from stainless steel hand tools to nickel‐titanium (Ni‐Ti) rotary tools. This paper aims to perform an in vitro comparative study to evaluate the efficacy of five endodontic manual and rotary instruments such as Kerr files ...

Plotino: Enéada III

, 2021
NonePlotino faz uma crítica aos que atribuem o destino ao acaso, aos astros, ou aos átomos. Para a criação, tudo que é e que vem a ser tem de depender de uma causa, mas essa causa não pode ser aleatória, nem direcionada por uma série de eventos que dão ...

Fifteen years of engine‐driven nickel–titanium reciprocating instruments, what do we know so far? An umbrella review

Australian Endodontic Journal, Volume 50, Issue 2, Page 409-463, August 2024.
Abstract Numerous systematic reviews (SRs) have produced conflicting findings on engine‐driven nickel–titanium reciprocating instruments (reciprocating instruments) since Yared's seminal study 15 years ago. This umbrella review analysed SRs examining the clinical and laboratory evidence regarding reciprocating instruments for root canal treatment.

Substance P/calcitonin gene‐related peptide and their receptors expression in human periodontal ligament after root canal preparation with five different systems

International Endodontic Journal, Volume 57, Issue 5, Page 576-585, May 2024.
Abstract Aim The purpose of this study was to quantify the effect of five different root canal preparation instruments on Substance P (SP), Calcitonin gene‐related peptide (CGRP) and their receptors expression in healthy human periodontal ligament. Methodology STROBE guidelines were used to design a study using 60 periodontal ligament samples obtained ...

Impact of pecking amplitude on cyclic fatigue of new nickel–titanium files

Clinical and Experimental Dental Research, Volume 10, Issue 1, February 2024.
Abstract Objectives The aim of this study is to determine the cyclic fatigue resistance of Mtwo Minimal in static and dynamic tests, with different amplitudes of pecking movements, at intracanal temperature. Materials and Methods Two hundred new 25‐mm Mtwo Minimal rotary files (#10/0.035, #17.5/0.045, #25/0.05, #40/0.03, #45/0.03) were tested in static
