Effectiveness of composite resin polymerization using light- emitting diodes (LEDs) or halogen-based light-curing units Efetividade de polimerização de uma resina composta fotopolimerizada por diodos emissores de luz (LEDs) ou luz halógena
The clinical performance of composite resins is greatly influenced by the quality of the light-curing unit used. The aim of this study was to compare the efficiency of a commercial light-emitting diode (LED) with that of a halogen-based light-curing unit by means of dye penetration of a micro hybrid composite resin. The composite resin evaluated was Filtek Z250 (3M Dental). The composite was fi...
متن کاملEffect of Three Light Curing Protocols and Load Cycling on Microleakage of Class V Composite Restorations
Objective: Different methods have been suggested to overcome the polymerization shrinkage of composite restorations. Changing the light curing protocol to improve polymerization by using new light curing units is among these methods. The new devices are more efficient, portable and durable and produce less heat. This study aimed to assess the marginal microleakage of class V composite restora...

متن کاملEffect of the number of thermocycles on microleakage of resin composite restorations Efeito do número de ciclos térmicos na microinfiltração de restaurações de resina composta
Thermocycling simulates, in vitro, thermal changes that occur in the oral cavity. The aim of this study was to evaluate the influence of the number of cycles on microleakage. Class V cavities (1.5 mm deep, 3 mm in height and 3 mm in width) were prepared in bovine teeth, restored with a Single Bond/Z250 restorative system (3M/ESPE) and then divided into five groups of ten teeth each: group 1 was...
متن کاملمقایسهی میزان ریزنشت حفرات کلاس II ترمیم شده با کامپوزیتهای سایلوران و متاکریلات بیس با استفاده از دوروش مختلف ترمیمی (روش ساندویچ باز، باندینگ)
Background and Objective: Polymerization shrinkage in composite resins is responsible for microleakage restoration. A recently introduced composite resin Filtek P90 is based on siloxanes and oxiranes which polymerize by cationic "ring opening" polymerization resulting in reduced polymerization shrinkage. The aim of this study was comparative evaluation of microleakage in class II cavities resto...
