AMAÇ: Restorasyonlarda kullanılan dental materyallerin radyoopasiteleri, radyografik tanıların konulmasında oldukça önemlidir. Bu sebeple çalışmamızda farklı akıcı kompozit rezinlerin dijital bir görüntü analizi kullanılarak radyoopasitelerinin değerlendirilmesi amaçlanmıştır.
YÖNTEM: 5 farklı akıcı kompozit rezin [ (Aeliteflo, BISCO), (Brillant Ever Glow, Coltène), (Dynamic Flow, President Dental), (G-ænial Universal Flo, GC Corp.), (Novo compo-HF, Imicryl)] her grup için üç adet disk şeklinde 1 mm kalınlığında 8 mm çapında örnek teflon kalıplar kullanılarak hazırlanmıştır. Kontrol grubu için yeni çekilmiş dişten mine ve dentini içerecek şekilde 1 mm kalınlığında kesit alınmıştır. Örnekler alüminyum step-kama ile birlikte okluzal film üzerine yerleştirilmiş ve 60 kV, 7mA ve 0.13sn değerlerinde dijital radyograf alınmıştır. VistaScan cihazıyla dijital ortama aktarıldıktan sonra alüminyum step-kamanın ve akıcı kompozit rezinlerin radyoopasiteleri Adobe Photoshop CS5 programıyla 10x10 piksellik farklı alanlardan hesaplamalarla ortalama grilik değerlerine (MGVs) çevrilmiştir. Akıcı kompozit rezinler için eşdeğer alüminyum kalınlığı CurveExpert Professional programı ile hesaplanmıştır.
BULGULAR: Kullanılan akıcı kompozit rezinlerin Al eşdeğer radyoopasitelerinin sıralaması; Novo compo-HF (2,81mm Al) > Brillant ever glow (2,15mm Al) > Aeliteflo (1,64mm Al) > Dynamic flow (1,61mm Al) > G-ænial Universal Flo (1,19 mm Al) (p<0,05) şeklindedir. G-ænial Universal Flo ve dentin 1mm Alüminyum radyoopasite değerine istatistiksel olarak en yakın sonucu vermiştir. Novo compo-HF mineden daha radyoopak olmakla beraber yakın MGV’ ye sahiptir.
SONUÇ: Akıcı kompozit rezinlerin radyoopasiteleri önemli ölçüde çeşitlilik göstermektedir. Akıcı kompozit rezinlerin, uygulanan kompozit rezin restorasyonların altında sekonder çürükle karıştırılmaması ve farklı materyal kullanıldığının belirlenebilmesi için farklı radyoopasite değerlerinde seçimler yapılabilir. Ayrıca radyografik analiz yapılırken bu farklı radyoopasite değerlerinin bilinmesi diagnostik değerlendirmede ve teşhiste yardımcı olacaktır.

COMPARATIVE RADIOPACITIES OF FIVE FLOWABLE RESIN COMPOSITES
AIM: The radiopacities of the dental materials in the restoration are very important in getting radiographic diagnosis. For this reason, we aimed to evaluate the radiopacity of different flowable composites using a digital image analysis.
METHODS: For the 5 different flowable resin composites [(Aeliteflo, BISCO), (Brillant Ever Glow, Coltène), ( Dynamic Flow, President Dental), ( G-ænial Universal Flo, GC Corp.), ( Novo compo-HF, Imicryl)]; 3 discs with a thickness of 1 mm and a diameter of 8 mm were prepared with using teflon mold. For the control group, a slice of 1 mm thickness was taken to contain enamel and dentin from the freshly extracted tooth. The samples were placed on an occlusal film with the aluminum step wedge and the film was exposed with a dental x-ray unit at 60 kV, 7 mA, and 0.13 second. After transferring to the digital image using VistaScan; the radiopacities of aluminum step-wedges and the flowable resin composites were converted to mean gray values (MGVs) from different areas which is 10x10 pixel by Adobe Photoshop CS5 program. Equivalent aluminum thickness for each flowable resin composite is calculated with the CurveExpert Professional Program.
RESULTS: The order of the Al equivalent radiopacities of the flowable resin composites used is as follows; Novo compo-HF (2,81mm Al) > Brillant ever glow (2,15mm Al) > Aeliteflo (1,64mm Al) > Dynamic flow (1,61mm Al) > G-ænial Universal Flo (1,19 mm Al) (p<0,05). G-ænial Universal Flo and dentin got the closest result to 1mm Aluminum radiopacity value statistically. The Novo compo-HF is more radiopaque than the enamel and has close MGV.
CONCLUSION: The radiopacity of flowable resin composites varies considerably, Selections can be made at different radiopacity values so that they do not be confused with secondary caries under the applied composite restorations and indicate that different materials are used. In addition, knowing these different radiopaque values while performing radiographic analysis will help diagnose.
Keywords: Flowable resin composites, radiopacity, mean gray value
