Abstract (2. Language): 
There has been a rapid increase in demand for esthetic restorative materials as well as light curing units since the introduction of single-paste light cured composites.İBecause of the polymerization of light -cured resins depends mainly on the characteristics and type of the radiation source used ,a way to achieve better properties of the final restoration cured is the improvement of the curing unit. Recently a new polymerization unit that has Light Emmitting Diod technology introduced to eliminate the disadvantages of convantional light curing units in polymerization. The objective of this is to determine the polymerization efficiency of three light curing units on two different thickness of different shades of composites. Freelight II that has the second generation Led technology shows significantly better depth of cure on both shades and thickness. Also we figure out that as the shades become more darker light intensity and the thickness of composite becomes more important because the light can not pass to deeper parts of composite.

Abstract (Original Language): 
Estetik restorasyonlara olan ihtiyacın artma¬sıyla birlikte uygun materyallerin geliştirilmesi için birçok araştırma yapılmaktadır. Bu çalışmalar son zamanlarda kompozit materyallerin polimerizasyo-nundaki dezavantajların ortadan kaldırılması amacıyla polimerizasyon sistemleri üzerinde yoğunlaşmıştır. Konvansiyonel halojen cihazlara alternatif olarak ortaya çıkarılan sistemlerden biri olan Light Emmiting Diod cihazları gerek ısı üretmemeleri gerekse dalga boyu uygunluğu avantajları nedeniyle son zamanlarda kompozit polimerizasyonunda kullanılmaya başlan¬mıştır. Çalışmamızda bu cihazların kompozit poli-merizasyonunda konvansiyonel halojen cihazlarına karşı olan avantajları değerlendirilmiştir. Kullanılan ışıklı cihazlardan 2. jenerasyon Led teknolojisini taşıyan FreeLight II ,diğer bütün cihazlara 40 sn ışınlama süresinde üstünlük sağlamıştır. 2 ve 3 mm kalınlığında A1 ve A3 renklerde hazırlanan kompozit blokların polimerizasyonu sonucunda kalınlık artışının ve koyu renkte kompozit polimerizasyonu-nun ışığın kompozitin derin noktalarına penetrasyo- nunu engellediği görülmüştür.
