the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...

Statement of Problem: The relatively poor wear resistance of dental composite in stress bearing posterior situations has restricted wider clinical application of this restorative material. Purpose: The aim of this study was to evaluate the three body abrasive wear of a dental composite based on a new filler (leucite: KAl Si2O6) and to compare it with the wear resistance of a composite based on ...

Introduction: One of the most important factors affecting the marginal seal of composite restorations is polymerization shrinkage. The aim of this study was to evaluate the micro leakage of two resin composites cured with two light directions. Methods: In this experimental study, forty similar class III preparations were prepared in 40 human anterior teeth. The teeth were randomly divided in t...
