Abstract

Light polymerized composite resins, for example minifil hybrid composites and condansable composites are commonly used in dentistry owing to their developed physical, mechanical and esthetical properties. LED Light Emitted diode light units are commonly used to polymerize the resin composites. Composite restorations may show color changes in several degrees in oral environment. These color changes of restorative materials occur in oral cavity caused by several physical and chemical factors; water, drinks etc. The aim of this study was to examinate the color changes of samples embedded in water and polymerized with a halogen and a LED light units. In the study, a posterior minifil hybrid composite material “Aélite Bisco, USA ” and a posterior condansable composite resin material “Solitaire 2 Heraeus Kulzer, Dormagen, Germany were used. They were polymerized with a conventional halogen and a LED light units. Color measurements of samples which were stored in deionised water were performed according to “CIE-L*a*b* color system” with a colorimeter device Minolta CR-321 at the times of “initial”, “after one week” and “after one month”. Data were determined with Three-Way-variance Analyse ANOVA and Duncan Multiple Comparison Test p

Abstract

Minifil hibrit kompozitler ve kondanse edilebilir kompozitler gibi ışıkla polimerize olan kompozit rezin materyaller, gelişmiş fiziksel, mekanik ve estetik özellikleri ve pratik kullanımları sebebiyle, diş hekimliğinde oldukça yaygın olarak kullanılmaktadırlar. Rezin kompozitlerin polimerizasyonlarında son zamanlarda, halojen ışık kaynaklarının yanı sıra, LED ışık saçan diyotlar olarak adlandırılan ışık kaynakları da sıklıkla kullanılmaya başlanmıştır. Kompozit restorasyonlar, ağız ortamında, çeşitli derecelerde renklenme gösterebilmektedirler. Bu renklenmeler; restoratif materyallerin ağız ortamında çeşitli fiziksel ve kimyasal etkenlere, su ve içecekler gibi çeşitli sıvılara maruz kalmaları sonucunda meydana gelebilmektedir. Bu çalışmada; halojen ve LED ışık cihazlarıyla polimerize edilen minifil hibrit ve kondanse edilebilir kompozit rezin materyalin suda bekletilmelerinin, kompozit rezinlerin renk stabiliteleri üzerine olan etkisinin incelenmesi amaçlanmıştır. Çalışmada, bir posterior minifil hibrid kompozit rezin “Aélite Bisco, USA ” ve bir posterior kondanse edilebilir kompozit rezin materyal “Solitaire 2 Heraeus Kulzer, Dormagen, Germany kullanılmış ve geleneksel halojen ve LED ışık kaynaklarıyla polimerize edilmişlerdir. Bir hafta ve bir ay deiyonize suda bekletilen örneklerin “başlangıç”, “1 hafta sonraki” ve “1 ay sonraki” renk ölçümleri, bir kolorimetre cihazıyla Minolta CR-321 , “CIE-L*a*b* renk sistemi” ’ne göre yapılmış ve verilerin istatistiksel olarak karşılaştırılmaları için 3-Yönlü-Varyans Analizi ANOVA ve Duncan Çoklu karşılaştırma Testleri kullanılmıştır p
