BackgroundTo assess the changes of implant surfaces of different roughness after instrumentation with ultrasonic-driven scaler tips of different materials.MethodsExperiments were performed on two moderately rough surfaces (I—Inicell® and II—SLA®), one surface without pre-treatment (III) and one smooth machined surface (IV). Scaler tips made of stee...

Abstract: The present study investigated the intracanal decontamination and apical extrusion of bacteria and debris from root canals instrumented with rotary and reciprocating systems (ProDesign Logic or ProDesign R), with different file diameters and using conventional syringe irrigation (CSI) or passive ultrasonic irrigation (PUI). Eighty extract...

Low power ultrasonics are used for testing high density polyethylene pipe material. Attenuation and velocity give valuable information on the material in situ and without damages. In this paper we revisit recent data in the frequency band (4,10) megahertz. We prove that propagation is equivalent to random delays following stable probability laws. M...

Background: The effectiveness of screening for macrosomia is not well established. One of the critical elements of an effective screening programme is the diagnostic accuracy of a test at predicting the condition. The objective of this study is to investigate the diagnostic effectiveness of universal ultrasonic fetal biometry in predicting the deli...

Separation of root canal instruments is a common incident during root canal treatments' procedures. The complex configuration of root canal systems is one of the most influencing factors, not only during the occurrence of instrument separation but also during the management of such unpleasant incidents. There are few reports on the management of fr...

A novel ultrasonically driven bio-reduction method was adopted to reduce the palladium chloride into palladium nanoparticles ([email protected]) using coleus amboinicus extract as a green synthetic protocol. XRD confirms the formation of phase pure cubic Pd nanoparticles with the crystallite size range of 40-50 nm. The UV-vis spectrum reveals the formation ...

Sonic and ultrasonic instrumentations generate vibrations that may influence debonding characteristics. The objective of this in vitro study was to assess the direct and indirect effects of sonic and ultrasonic periodontal instrumentations on the shear bond strength (SBS) and the adhesive remnant index (ARI) scores of metallic orthodontic brackets....
