Amaç: Bu çalışmanın amacı üç farklı ışık cihazı ile
polimerize edilen bulk-fill kompozitlerde, kalınlığın artışının mikrosertlik
üzerine etkisinin incelenmesidir. 

Gereç ve Yöntemler:İki farklı bulk-fill kompozit (Tetric Evo Ceram Bulk
Fill, X-trafil) ve bir adet akışkan bulk-fill kompozit (SDR) kullanıldı.
Kompozitler 1mm derinliğinde 5 mm çapında, dört metal kalıba yerleştirilerek
iki farklı LED ışık cihazı (Blue Phase
and Valo) ve bir adet
halojen ışık cihazı (Hilux) ile polimerize
edildi. Örnekler 24 saat 37°C’de  %100 nemli ortamda bekletildi. Vickers sertlik
ölçümleri 5 saniye 100 gr kuvvet uygulanarak yapıldı. Her örneğin hem üst hem
de alt yüzeyinden 3 ölçüm yapıldı. Elde edilen veriler 0.05 istatistik seviyede
analiz edildi. 

Bulgular:Hem üst hemde alt yüzeylerde bütün ışık cihazları ile
polimerize edilen X-tra fill diğer gruplara göre belirgin düzeyde yüksek
sertlik değerleri göstermiştir (p<0.05). SDR dışında ışık cihazlarındaki
farklılık kompozit gruplarının sertliğini değiştirmemiştir (p>0.05). Sadece
SDR, Blue phase ile polimerize edildiğinde diğer ışık cihazlarına göre daha
düşük sertik değerleri göstermiştir (p<0.05). Kompozit tabakaları ile
sertlik arasındaki ilişki incelendiğinde, halojen ile polimerize edilen Tetric
Evo Ceram ve X-trafill kompozitlerin 1. ve 4. mm’de sertlikte belirgin düzeyde fark
gözlenmiştir (p<0.05). Halojen ile polimerize edilen SDR kompozit örneklerinde
fark tespit edilmemiştir (p>0.05).

Sonuçlar: Kompozitlerin sertlikleri materyal, ışık cihazı ve
derinliğe bağlı olarak değişmektedir
