Abstract

Amaç: Restorasyonlarda kullanılan dental
materyallerin radyoopasitesi sekonder çürüklerin
teşhisi, çürüğün restoratif materyalden ve diş
dokusundan ayrılması, marjinal defektler,
taşkınlıklar, açık marjinlerin tespiti ve pulpaya
yakınlığın radyografik tanısında son derece önemli
bir unsurdur. İdeal klinik performans için ihtiyaç
duyulan radyoopasite derecesi materyalin türüne
göre değişiklik göstermektedir. Radyoopasite ile
ilgili çalışmalar genellikle mine, dentin ve
alüminyum ile kıyaslanarak yapılmaktadır. Bu
çalışmada cam iyonomer ve rezin esaslı farklı
kaide materyallerinin radyoopasiteleri incelenerek;
bunların mine, dentin ve alüminyum stepwedge’in
radyoopasiteleri ile karşılaştırılması amaçlandı.
Gereç ve Yöntemler: Sıklıkla kullanılan 5 kaide
materyalinden (Nova Glass-F, Equia Fil, Ionofil,
Vertise Flow, G-aenial Universal Flo) 10 mm
çapında, 1 mm kalınlığında plastik disk şekilli
örnekler hazırlandı. Yeni çekilmiş 3.molar
dişlerden 1mm kalınlığında kesit alındı. Bütün
örnekler fosfor plak üzerine yerleştirilerek fokal
spot mesafesi 30 cm olacak şekilde 70 kVp ve 7
mAs’e görüntü alındı. Alınan görüntü Image J
programına aktarılarak Mean Grey Value ölçüldü.
Ölçülen değerin mmAl karşılığı hesaplanarak
varyans analizi ve Tukey test ile analiz edildi.
Bulgular: Vertise Flow, Nova Glass-F ve Equia Fil
dentinden belirgin ölçüde yüksek radyoopasite
değeri gösterirken (p < 0,05 ), İonofil ve G-aenial
Universal Flo dentin ile benzer radyoopasite
değeri göstermiştir (p > 0,05). Cam iyonomer
içerikli kaide materyallerinin radyoopasite
değerleri istatistiksel olarak benzer görülürken
(p > 0,05), rezin esaslı kaide materyalleri
birbirlerinden belirgin ölçüde farklı değerler
göstermiştir (p < 0,05).
Sonuç: Restoratif materyalin ve kaide materyalinin
yeterli radyoopasiteye sahip olması önemli bir
ihtiyaçtır. Buna karşılık piyasada yetersiz
radoopasiteye sahip bazı kaide materyalleri de
mevcuttur. Kaide materyallerinin radyoopasitesini
değerlendiren çalışmalar periyodik olarak
yapılmalıdır.

Abstract

Background: The radiopacity of cavity base materials has been considered as an important requirement, improving the radiographic diagnosis. The advantages of radiopacity over radiolusent materials are the easy detection of recurrent dental caries and observation of the radiographic interface between the materials and tooth surfaces. This study aims to investigate the radiopacity of glass ionomer cements (GICs) and flowable resin composites (FRCs) using a digital phosphor plate, comparing them to the dental tissues (enamel-dentine), expressed as equivalent thickness of aluminum.Methods: Three disk-shaped specimens, 10 mm in diameter and 1 mm in thickness were prepared for each material. Specimens of enamel and dentine with the same thickness were obtained as a control. After setting of the base materials, specimens were placed on a phosphor plate together with aluminum step-wedge ( 1 to 16 mm in thickness ) and were exposed using a dental x-ray unit. Three measurements of radiographic density were obtained from each image of each item assessed ( base material, enamel, dentin, each step of the aluminum step-wedge) and the mean of these values was calculated. Radiopacity values were later calculated as equivalents of aluminum thickness. Data were analyzed by ANOVA and Tukey’s test.Results: As the Vertise Flow is the only material that showed higher radiopacity than enamel, other materials presented significantly lower radiopacity than it (p < 0.005). Vertise Flow, Nova Glass-F and Equa Fil showed significantly higher radiopacity than dentine (p < 0.005). However, no significant difference in radiopacity was observed between G-aenial Universal Flo, Ionoseal and dentine (p > 0.05).Conclusion: Equia Fil, Nova Glass-F, and Vertise Flow have higher radiopacity than dentin. However radiopacity value of base materials varies considerably. So this should be taken seriously when selecting materials.
