introduction: the purpose of this study was to compare the subcutaneous tissue responses of freshly mixed or set endodontic root canal sealers ( i.e. roekoseal, ah26, ah plus) in wistar albino rats. materials and methods: seventy-two male albino rats weighing 200-250g were used. the animals were randomly divided into six groups of 12 rats each. root canal sealers were implanted in subcutaneous ...

New medical products, materials and surgical procedures keep improving current health-care practices. Many of these innovations involve polymeric devices that must meet certain clinical and cost requirements. Chief among these pressures is the need for biocompatibility between the physiological environment and the biomaterial surface. Plasma surface modification can improve biocompatibility and...

statement of problem: many attempts have been made in order to evaluate the amalgam corrosion behavior as an indicator of biocompatibility. purpose: the aim of this study was to evaluate and compare the initial corrosion of four different brands of dental amalgams. materials and methods: four different types of commercial high copper dental amalgam were studied. a special mold was used and twen...

abstract: background and aim: resin cements are used widely in restorative dentistry regardless of their biocompatibility. the aim of this study was to compare the cytotoxicity of two categories of dental cements consisting of three chemically set cements (fuji i, fuji plus and harvard) and two dual curing cements (biscem and duo-link) by use of mtt assay. materials and methods: in this experim...

The manner in which a mutually acceptable co-existence of biomaterials and tissues is developed and sustained has been the focus of attention in biomaterials science for many years, and forms the foundation of the subject of biocompatibility. There are many ways in which materials and tissues can be brought into contact such that this co-existence may be compromised, and the search for biomater...

INTRODUCTION Biocompatibility ranks as one of the most important properties of dental materials. One of the criteria for biocompatibility is the absence of material toxicity to cells, according to the ISO 7405 and 10993 recommendations. Among numerous available methods for toxicity assessment; 3-dimensional Confocal Laser Scanning Microscopy (3D CLSM) imaging was chosen because it provides an a...

Background: Improvements in the biocompatibility of dialysis membranes have reduced biological responses elicited by blood–membrane interactions. In this article, recent technological developments in dialysis membranes with regard to biocompatibility and recent progress in the evaluation of the biocompatibility of dialysis membranes are reviewed. Summary: The focus of investigation into dialysi...
