Abstract

Objective: The aim of this study was to evaluate change in radiopacity of two root canal sealers with the change in exposure parameters (kilovoltage, milliampere and exposure time) using conventional film radiography. Material and Method: The root canal sealers used were Diaket and MM Seal. Standard disks of 2 different sealers were exposed together with an aluminum (Al) step wedge by using a D-speed occlusal film. Each sample was radiographed using 60 and 70 kVp, 7 and 8 mA with three different exposure times (0.40, 0.50, 0.60 s). Optical density of the sealers and the Al step-wedge was evaluated by transmission densitometry, The radiographic density of each specimen was measured and correlated with the equivalent thickness of aluminum. Three-way analysis of variance was used to compare the differences between groups (p=0.05). Results: No significant differences were found in radiopacities of sealers with respect to different kVp, mA and exposures used in this study (p>0.05). At all radiologic parameters used in this study MM Seal was more radiopaque than Diaket (p

Özet

Amaç: Farklı kilovoltaj, miliamper ve ışınlama süresi parametrelerinin geleneksel radyografide kök kanal patının radyoopasitesi üzerine etkisini değerlendirmektir. Gereç ve Yöntem: Çalışmada Diaket ve MM Seal kullanıldı. Her iki cins kanal patından birer örnek ve alüminyum penetrometre, D-hızında okluzal bir film kullanılarak 60 ,70 kVp; 7,8 mA; 0.40, 0.50, 0.60 sn ışınlama parametreleri kullanılarak radyografları elde edildi. Kanal patlarının radyografik densitesi ve Al penetrometrenin tüm basamakları dijital transmisyon densitometrisi ile değerlendirildi. Kilovoltaj, miliamper ve ışınlama süresi göz önüne alındığında kanal patlarının radyodensiteleri arasındaki farklar ve her üç faktörün birbirleriyle olan ilişkisi üçlü varyans analizi kullanılarak karşılaştırıldı. Bulgular: Tüm ışınlama parametrelerindeMMSeal’in Diakete göre anlamlı olarak daha radyoopak olduğu saptandı (p0.05) Sonuç: Her iki kök kanal patı da ISO tarafından önerilen radyoopasite standartları içindedir. KvP, mA ve ışınlama süresi parametrelerindeki minör değişiklikler radyografik densite üzerinde anlamlı bir farklılık oluşturmamaktadır.
