Comparison of Surface Hardness of Various Shades of Twinky Star Colored Compomer Light-cured with QTH and LED Units
INTRODUCTION Colored compomers are a group of restorative materials that were introduced in 2002 to repair primary teeth, and they provide attractive color and ease of use in pediatric dentistry. The aim of this study was to evaluate the effect of QTH and LED light-curing units on the surface hardness of different colors of Twinky Star compomers. METHODS In this experimental study, a composit...
متن کاملvickers hardness of composite resins cured with led and qth units
statement of problem: one of the factors affecting the degree of polymerization of light-cured composites is the type of light-curing unit used. in addition, physicomechanical properties of composite resins depend on the degree of conversion and polymerization. objectives(s): since the type of initiator in new composite resins is not explained by manufacturers, this study is an attempt to compa...
متن کاملPolymerization of a dual-cured cement through ceramic: LED curing light vs halogen lamp.
The aim of this study was to investigate the influence of light source, LED unit and halogen lamp (HL), on the effectiveness of Enforce dual-cured cement cured under a ceramic disc. Three exposure times (60, 80 and 120 s) were also evaluated. Two experimental groups, in which the polymerization of the dual-cured cement was performed through a ceramic disc, and two control groups, in which the p...
متن کاملCuring depth of composite resin light cured by LED and halogen light-curing units
The purpose of this study was to evaluate the polymerization effectiveness of a composite resin (Z-250) utilizing microhardness testing. In total, 80 samples with thicknesses of 2 and 4 mm were made, which were photoactivated by a conventional halogen light-curing unit, and light-curing units based on LED. The samples were stored in water distilled for 24 h at 37 ° C. The Vickers microhardness ...
متن کاملThe Effect of Irradiation Distance on Microhardness of Resin Composites Cured with Different Light Curing Units
OBJECTIVES The aim of this study was to compare the microhardness of five different resin composites at different irradiation distances (2 mm and 9 mm) by using three light curing units (quartz tungsten halogen, light emitting diodes and plasma arc). METHODS A total of 210 disc-shaped samples (2 mm height and 6 mm diameter) were prepared from different resin composites (Simile, Aelite Aesthet...
