New technique for microscopical examination of the powdered dental materials with transmitted light microscope by using "Talia Indicator"

Abstract

The aim of this study is to examinethe physical from of the powder particles of the dental materials by microscopical examination.Dried powder can't beexamined microscopically with ordinary transmitted light microscope, but need special microscope like reflected light microscope or electron microscope.In this study a new technique for microscopical examination of the powder particles was performed with transmitted light microscope by using a special indicator named "Taha Indicator".The technique is easy,cheep and give clear and accurate image of the powder particles, so it can be used in studies and researches as a method for evaluation, comparison and differentiation between thedifferent types of thematerial, it has a great benefit for the industration and in discovering the industrial deceit of dental materials.
