ÖZET
 Amaç: Çalışmamızın amacı, son yıllarda kullanımı yaygınlaşan, bulk fill kompozit rezinlerin, farklı ışık cihazları ile polimerizasyonunun, su emilimi ve çözünürlük değerleri üzerine olan etkisini incelemektir. Gereç ve Yöntemler: Çalışmamızda 8 farklı bulk fill kompozit rezin; SDR (Dentsply), Sonicfill (Kerr), x-traFil (Voco), Beautifil Bulk Restorative (Shofu), Beautifil Bulk Flowable (Shofu), Filtek Bulk Fill Flowable (3M ESPE), Admira Fusion X-tra (Voco), Estelite Bulk Fill Flow (Tokuyama) ve mikrohibrit tipte Filtek Z250 Universal (3M ESPE) kullanılarak 6 mm çapında, 4 mm kalınlığında örnekler hazırlanmış, LED ve QTH ışık kaynakları ile polimerize edilmiştir. Örneklerin su emilim ve suda çözünürlük düzeylerini saptamak için, ISO 4049:2009 spesifikasyonu esas alınarak, standartta bildirilen formüllerden yararlanılmıştır. Kompozit ve ışığa göre çözünürlük ve su emilimi karşılaştırmalarında, Kruskal-Wallis, bağımsız örneklem t-testi ve Mann-Whitney U testleri uygulanmıştır. Farkın belirlenmesinde, ''post hoc'' Bonferroni testi kullanılmıştır. Önem düzeyi p<0,05 olarak alınmıştır. Bulgular: Işık cihazlarının hem su emilimi hem de çözünürlük üzerinde etkisi anlamlı bulunmuştur (p<0,05). Beautifil-Bulk Restorative kompozit grubunda çözünürlük değeri, Admira Fusion X-tra ve Estelite Bulk Fill Flow grupları ile karşılaştırıldığında anlamlı derecede yüksektir (p=0,001 ve p=0,041). En yüksek su emilimi ortalama değeri, Beautifil-Bulk Restorative ve QTH etkileşimi ile elde edilmiştir ve 20,37'dir. En düşük su emilimi ortalama değeri, x-traFil kompozitinde hem LED hem QTH ile 8,8'dir. Sonuç: Kompozit rezinlerin yapısı ve polimerizasyonda kullanılan ışık cihazları, su emilimi ve çözünürlük düzeylerini etkilemektedir.

ABSTRACT
 Objective: The aim of our study is to examine the effects of polymerization of bulk fill composite resins, which have become widely used in recent years, with different light devices on water absorption and solubility levels. Material and Methods: Samples with a diameter of 6 mm and a thickness of 4 mm were prepared by using 8 different bulk fill composite resins SDR (Dentsply), Sonicfill (Kerr),x-traFil (Voco), Beautifil Bulk Restorative (Shofu), Beautifil Bulk Flowable (Shofu), Filtek Bulk Fill Flowable (3M ESPE), Admira Fusion X-tra (Voco),Estelite Bulk Fill Flow (Tokuyama) and microhybrid Filtek Z250 Universal (3M ESPE) and they were polymerized with LED and QTH light sources.In order to determine the water absorption and water solubility levels of the samples,the formulas reported in the standard were used,based on ISO 4049:2009 specification. Kruskal-Wallis, Independent Sample T and Mann-Whitney U tests were applied for solubility and water absorption comparisons according to composite and light. ''Post hoc'' Bonferroni test was used to determine the difference. Significance level was taken as p<0.05. Results: The effect of light devices on both water absorption and solubility was significant (p<0.05). The solubility value was significantly higher in the Beautifil Bulk Restorative composite group compared to the Admira Fusion X-tra and Estelite Bulk Fill Flowable groups (p=0.001 and p=0.041).The highest mean value of water absorption was obtained with the interaction of Beautifil Bulk Restorative and QTH and was 20.37. The lowest mean value of water absorption was 8.8 in x-traFil composite with both LED and QTH. Conclusion: The structure of composite resins and light devices used in polymerization affect water absorption and solubility levels.
