Abstract

Amaç: Bu çalışmanın amacı, iki farklı tabaka kalınlığında ve iki farklı ışık gücünde polimerize edilen üç farklı bulk fill kompozit rezinin basma dayanımının değerlendirilmesidir.
Gereç ve Yöntem: Bu çalışmada, üç farklı bulk fill kompozit rezin (SonicFill 2, Kerr Dental, Orange, CA, ABD- Filtek Bulkfill 3M, ESPE, St. Paul, MN, ABD- EverX Posterior, GC, Leuven, Belçika) kullanılmıştır. Her grupta 10 numune olacak şekilde 5 mm çapında, 4 ve 6 mm kalınlıklarında ve her bir kalınlık tek tabaka olarak iki farklı ışık güç modunda (1000 mW/cm2, 3 sn - 3200 mW/cm2, 20 sn) ayrı ayrı polimeriz edilerek 120 numune hazırlandı. Toplamda 12 grup oluşturuldu. Teflon kalıplardan çıkarılan örneklerin kalınlıklarının standardizasyonunu sağlamak için örnekler dijital kumpas (Mitutoyo Digimatic) kullanılarak ölçüldü. Hazırlanan örneklerin alt ve üst yüzeyleri birbirine paralel hale getirilmek için Sof-Lex (3M ESPE Dental Products, St Paul, MN, USA) cila diskleri kullanılarak kalından inceye doğru sırası ile her bir örnek kuru ve tek yönlü olarak mikromotor ile 15000 rpm düşük devirde cilalandı. Ardından örneklere Universal test cihazı (Zwick/Roell Z250, Almanya) kullanılarak, basma dayanımı testi 1 cm/dk çapraz kafa hızında yapıldı.
Bulgular: Sonic Fill ve Filtek Bulk Fill kompozit rezinlerde ışık şiddetinin basma dayanımına istatistiksel olarak anlamlı bir etkisi gözlenmemiştir (p>0,05). Sadece EverX Posterior kompozit rezinin 6 mm kalınlığındaki örneklerinde ışık şiddeti arttırıldığında basma dayanımı değerleri istatistiksel olarak anlamlı bir şekilde azalmıştır (p<0,05). Tabaka kalınlığının artması EverX Posterior kompozit rezin dışında basma dayanımını istatistiksel olarak anlamlı şekilde etkilememiştir (p<0,05). Tüm gruplar arasında en yüksek değeri ekstra güç modunda polimerize edilen 4 mm kalınlığında hazırlanan EverX Posterior kompozit rezin örnekleri, en düşük değeri ise ekstra güç modunda polimerize edilen 6 mm kalınlığında hazırlanan Sonic Fill kompozit rezin örnekleri göstermiştir.
Sonuç: Standart güç modunda polimerize edilen örneklerde tabaka kalınlığı basma dayanımını değerlerini etkilemezken, ekstra güç modunda tabaka kalınlığı basma dayanımı değerlerini etkilemektedir.

The Effect of Polymerizing Bulk Fill Composite Resins at Different Layer Thicknesses and Two Different Light Power on the Compressive Strength of the Composite

Abstract

Objective: The aim of this study is to determine the compressive strength values of three different bulk fill composite resins polymerized at two different layer thicknesses and two different light power.
Material and methods: In this study, three different bulk fill composite resins (SonicFill 2, Kerr Dental, Orange, CA, USA- Filtek Bulkfill 3M, ESPE, St. Paul, MN, USA- EverX Posterior, GC, Leuven, Belgium) were used. A total of 10 samples in each group, 5 mm in diameter, 4 and 6 mm thick, and each thickness was polymerized separately in two different light power (1000 mW/cm2, 3 sec - 3200 mW/cm2, 20 sec) modes as a single layer and 120 samples were prepared. A total of 12 groups were created.The samples were measured using digital calipers (Mitutoyo Digimatic) in order to standardize the thickness of the samples extracted from Teflon molds. Sof-Lex polishing discs (3M ESPE Dental Products, St Paul, MN, USA) were used to bring the bottom and top surfaces of the prepared samples to each other, and each sample was polished in a dry and unidirectional order with a micromotor at low speed of 15000 rpm. Subsequently, the compressive strength test was performed on the samples using a Universal test device (Zwick / Roell Z250, Germany) at 1 cm / min crosshead speed.
Results: There was no statistically significant effect of light intensity on compressive strength in Sonic Fill and Filtek Bulk Fill composite resins (p> 0.05). When the light intensity was increased only in 6 mm thick samples of EverX Posterior composite resin, the compressive strength values decreased statistically significantly (p> 0.05). The increase in layer thickness did not significantly affect the compression strength, except for EverX Posterior composite resin (p <0.05). Among all groups, the 4 mm-thick EverX Posterior composite resin samples polymerized in the extra power mode had the highest value, while the lowest value was the 6 mm-thick Sonic Fill composite resin samples polymerized in the extra power mode.
Conclusion: While the layer thickness does not affect the compressive strength values in the samples polymerized in the standard power mode, the layer thickness in the extra power mode affects the compressive strength values.
