background: the aim of this study was to compare the accuracy of the apex-locating functions of dentaport zx, raypex 5 and endo master electronic apex locators (eals) in vitro. materials and methods: thirty extracted human single-rooted teeth with mature apices were used for the study. the real working length (rwl) was established by subtracting 0.5 mm from the actual root canal length. all tee...

Abstract Lubricants for stern tube systems are subject to increasingly stringent requirements in terms of environmental compatibility, as any lubricant leakage leads contamination the sea. As a result, interest environmentally acceptable lubricants (EALs) is increasing. Biodegradable ester represent possible alternative conventional, mineral oil-based lubricants. In addition compatibility requi...

AIM To compare in vivo the Apex Finder and Root ZX electronic apex locators (EALs) at five different stages during root canal instrumentation. METHODOLOGY The Apex Finder and Root ZX were used in 64 teeth with either vital or necrotic pulps. Informed consent was obtained by each patient under a study protocol approved by an ethical committee from the University of Trieste. Measurements were m...

BACKGROUND Correct working length determination is an important step for successful endodontic therapy. OBJECTIVE The objective was to compare in vitro the accuracy of three electronic apex locators (EALs) (DentaPort ZX [Morita Co., Tokyo, Japan], SIROEndo Pocket [Sirona Dental Systems, NY, USA], and Rootor [Meta Biomed, Cheongwon-gun, Korea]) in detecting the major foramen using the clearing...

OBJECTIVES The purpose of this in vitro study was to evaluate the accuracy of working length (WL) determination of four electronic apex locators (EALs), namely, Root ZX (RZX), Elements diagnostic unit and apex locator (ELE), SybronEndo Mini Apex locator (MINI) and Propex pixi (PIXI) using Stainless steel (SS) and nickel-titanium (NiTi) hand files. The null hypothesis was that there was no diffe...

Background: One of the significant stages during endodontic procedures is determining correct working length (WL). This study aimed to evaluate accuracy four electronic apex locators (EALs) (Root ZX mini, Raypex 6, Propex Pixi, and E-Pex Pro) cone-beam computed tomography (CBCT) radiographic measurement in actual WL (A-WL).

Today, farmers are multioptional entrepreneurs, demanding far more skills than only those of agricultural production. The awareness European landscape (EAL) values should enable to create new business strategies. Open education repositories (OERs) based on online vocational and training (VET) still not widespread. project FEAL (multifunctional farming for the sustainability EALs) has brought in...

INTRODUCTION The purpose of this study was to compare the accuracy of the Root ZX II Apex Locator (RZX), the Elements Apex Locator (ELE), and the Precision Apex Locator (PAL). METHODS Forty single-rooted extracted teeth were decoronated and the root canals coronally flared. Actual canal lengths were determined by inserting a #10 file until the tip was visualized (12.8x magnification) just wit...

PURPOSE: The purpose of this study is to provide a preliminary assessment of Environmentally Acceptable Lubricants (EALs) for application in dams that are managed by the U.S. Army Corps of Engineers (USACE). The assessment will explore the environmental aspects of these lubricants and will also discuss their operational characteristics. This assessment is primarily through the literature availa...
