Nanosized iron oxide particles exhibit osteogenic and radiopaque properties. Thus, iron oxide (Fe3O4) nanoparticles were incorporated into a biodegradable polymer (poly-L-lactic acid, PLLA) to fabricate a composite bone screw. This multifunctional, 3D printable bone screw was detectable on X-ray examination. In this study, mechanical tests including three-point bending and ultimate tensile stre...

INTRODUCTION The aim of the study was to evaluate the radiopacity, solubility, flow, film thickness, setting time, and adaptation to the root canal walls of 3 epoxy resin-based sealers: AH Plus, Acroseal, and Adseal. METHODS Physical tests were performed following American National Standards Institute/American Dental Association's requirements. For interfacial adaptation analysis, 30 maxillar...

Calcium silicate-based materials (also called MTA) are increasingly being used in endodontic applications. However, the handling properties of MTA are not optimal when it comes to injectability and cohesion. Premixing the cements using glycerol avoids these issues. However, there is a lack of data on the effect of common cement variables on important properties of premixed cements for endodonti...

Introduction: The term of idiopatic osteosclerosis (I.O) have been used to describe a localised area of radiopacity of unknown origin. The condition is usually asymptomatic and discovered on a radiograph taken for other reason. The radiopacity is variable in size, shape, outline and density. The purpose of this investigation was to determine the frequncy, age and sex distribution and anatomic ...

The incorporation of metallic oxides in dental adhesives has been a strategy to confer improved radiopacity and physicochemical properties for polymers. Tailoring the structure these fillers could contribute their application therapeutic strategies restorations. aim this study was evaluate niobic acid into experimental adhesives, compare niobium pentoxide containing adhesives. A control group w...
