Comparison of light transmittance in different thicknesses of zirconia under various light curing units

PURPOSE The objective of this study was to compare the light transmittance of zirconia in different thicknesses using various light curing units. MATERIALS AND METHODS A total of 21 disc-shaped zirconia specimens (5 mm in diameter) in different thicknesses (0.3, 0.5 and 0.8 mm) were prepared. The light transmittance of the specimens under three different light-curing units (quartz tungsten ha...

Light transmittance of zirconia as a function of thickness and microhardness of resin cements under different thicknesses of zirconia

OBJECTIVE The objective of this study was to compare microhardness of resin cements under different thicknesses of zirconia and the light transmittance of zirconia as a function of thickness. STUDY DESIGN A total of 126 disc-shaped specimens (2 mm in height and 5 mm in diameter) were prepared from dual-cured resin cements (RelyX Unicem, Panavia F and Clearfil SA cement). Photoactivation was p...

Hardness of composite resin polymerized with different light-curing units

Introduction: The degree of polymerization depends on the type of light-curing unit. The aim of this study was to compare the hardness of composite resin cured by LED and Halogen light curing units. Methods: In this experimental study, 20 cylindrical samples of Tetric Ceram composite were prepared. Half of them were cured with Ultralume 2 LED and the other half with Astralis 7 Halogen light ...

gradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism

ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
