Evaluation of Surface Characteristic Changes of WaveOne Gold and WaveOne Single Reciprocating Files Using Scanning Electron Microscopy: An in-vitro Study

Introduction: The purpose of this study was to evaluate surface topography of WaveOne Gold (WOG) and WaveOne (WO) files using SEM before and after use. Methods: Twelve primary files from each system were scanned for surface defects before instrumentation at 100x and 750x. Each file was planned ti be used to instrument six root canals and then examined under SEM after preparing one, three and six...

Effect of the Synthesis Parameters on the Properties of Biphasic Ca(OH) -HA Nanopowders for Tissue Engineering Applications

      Nanocrystalline hydroxyapatite was precipitated from calcium hydroxide and phosphoric acid. Effects of precipitation temperature and different calcium to phosphate ratios (Ca/P) on the obtained powders were investigated. Characteriza-tion of the powders was performed using XRD and FTIR spectra, scanning electron microscopy, and transmission electron microscopy. Increase in precipitation t...

Methodologies to Analyze the Micromorphological Alterations of Enamel Subjected to Abrasion/Erosion

The incidence of caries has declined; however, other dental lesions such as tooth wear are becoming increasingly important. Dental wear is a multifactorial process that may encompass erosion, abrasion, and combinations thereof. Therefore, various methodologies have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by abrasive and erosive cha...

Evaluation of Different Sterilization Methods on the Uniformity of Diamond Dental Burs and the Change in the Cutting Edge of Carbide Burs by Electron Microscopy

Introduction: Dental burs are one of the most commonly used materials in dental offices and have, therefore, the highest risk of cross-contamination. Accordingly, sterilization of dental burs is highly recommended. Using the electron microscopy, this study aimed to evaluate the results of different sterilization methods on the uniformity of diamond dental burs and the change in the cutting edge...

Scanning Electron Microscopy and Energy-Dispersive X-ray Analysis of Root Cementum in Patients with Rapidly Progressive Periodontitis

A comparison of the anatomical structure of odontoblasts and the connective tissue fibres in relation to the age of the patient.

The aim of this work was to study the structure of dental pulp (mainly the connective tissue fibre and odontoblasts) during the active production of dentine in relation to the age of the patient. The pulps of the teeth extracted for orthodontic reasons from a population of 10-50 year-olds were investigated with the help of a transmission electron microscope (TEM) and a scanning electron microsc...
