Abstract

The aim of this study was to compare the coronal leakage of different root canal obturation techniques. In this study, 70 mandibular premolar teethwere used. Sixty teeth were divided into 4 groupsconsisting of 15 teeth. After preparation, the rootcanals were obturated with lateral condensation,System-B, Thermafil and MicroSeal root canalobturation systems. After obturation of the rootcanals the teeth were incubated in 100% humidityat 37ºC for 10 days to allow the sealer to set completely. After preparation of the leakage model system, india ink was placed in the coronal chambersand incubated in 100% humidity at 37ºC for 30days. The teeth were sectioned longitudinally, andthe maximum extent of leakage was measuredusing a stereomicroscope at x10 magnification. Theresults were analysed statistically using one wayANOVA and Bonferroni test. According to the results of our study, SystemB showed less dye leakage than Thermafil and thedifference was statistically significant p0.01

Abstract

Bu çalışmanın amacı, çeşitli kök kanal dolgutekniklerinin boya penetrasyon yöntemi kullanılarak koronal sızıntılarının karşılaştırılmasıdır Çal›şmam›zda, 70 adet tek köklü alt premolar dişler kullan›ld›. Altm›ş adet diş 15’erli 4 gruba ayr›ld›. Kök kanallar›, lateral kondenzasyon, System-B, Thermafil ve MicroSeal kanal dolgu sistemleri ile dolduruldu. Kanallar doldurulduktan sonra patlar›n sertleşmesi için dişler 37ºC’de %100 nemli ortamda 10 gün süreyle etüvde bekletildi. Ependorf tüplerinin içine Çini mürekkebi konuldu ve örnekler 30 gün süre ile 37ºC’de etüvde bekletildi. 30 günün sonunda dişler düzenekten söküldü ve elmas diskler yard›m›yla uzunlamas›na ikiye ayr›ld›. Elde edilen kesitler x10 büyütmede stereomikroskop alt›nda incelendi ve lineer olarak boya penetrasyon miktar› ölçüldü. Elde edilen ölçümler, tek yönlü varyans analizi ANOVA ve Bonferroni testi ile istatistiksel olarak değerlendirildi. Çal›şmam›zdan elde edilen bulgular sonucunda koronal boya s›z›nt›s› yönünden System-B ile doldurulan kanallarda, Thermafil’e göre daha az boya s›z›nt›s› olduğu gözlenmiştir p0.01 .
