Objectives: This study was examined thesurface microhardness of three kind of bulk fillcomposites Surefil SDR flow, Tetric, EvoCeram,X-tra base)Materials and Methods: Ten specimens of2mm, 4mm thickness and 4mm diameter of eachbulk fill composite were polymerized using ahalogen light and a blue light-emitted diode.Microhardness evaluation was performed at the topand bottom surfaces for each specimen using aVickers microhardness tester.Results: All of the materials were cured withthe light sources and the values obtained for thebottom surfaces were found to be lower than thevalues of top surfaces. Highest microhardness level(40.02±4.06)among all composite materialsbelonged to Xtra base composite group, whereaslowest microhardness level (5.80±0.83) was ofSDR composite specimens.Conclusions: Hardness ratio range was between0.19±0.3 and 0.72±0.06. Hardness ratio value wasfound to be lower than 0.80 for all compositegroups.

Özet
Amaç: bu çalışma üç farklı bulk fill kompozit (Surefil SDR flow, Dentsply, Caulk, USA and Tetric, EvoCeram, Ivoclar Vivadent, Schaan, Liechtenstein, X-tra base, Voco, Cuxhaven, Germany) mikrosertliklerinin araştırılmasıdır.
Gereç Yöntem: Çalışma için 4mm ve 2mm kalınlığında 4mm yarı çapında hazırlanan herbir bulk fill kompozit Plama ark ışık kayanağı kullanılarak polimerize edildi. Her bir örneğin alt ve üst mikrosertlik değerlendirmeleri Vickers mikrosertlik test cihazı kullanılarak yapıldı
Bulgular: çalışmada kullanılan tüm materyallerin polimerizasyonu ışık kaynağı ile yapıldıktan sonra alt yüzeylere ait sertlik değeri üst yüzeylerden daha düşük bulundu. Tüm komozitler arasında en yüksek Vickers sertlik değeri (40.02±4.06) olan grup üst Xtra base bulk fill kompozitine aitdir. En düşük Vickers sertlik değeri (5.80±0.83) alt ölçüm yapılan SDR bulk fill grubuna aittir.
Sonuç: Tüm örnek gruplarına ait sertlik oranı 0.80 den daha düşük bulundu.örnek gruplarına ait sertlik oranı 0,19±0,3 ile 0,72±0,06 arasındadır.
Anahtar kelimeler: mikrosertlik, akışkan kompositler, sertlik oranı
