Farklı kök kanal patlarının apikal mikrosızıntılarının değerlendirmesi

Bu çalışmanın amacı farklı kök kanal patlarının apikal mikrosızıntılarını boya sızıntısı yöntemiyle karşılaştırmaktır. 47 adet tek köklü diş, kök boyları 14 mm olacak şekilde mine-sement sınırında kronlarından ayrıldı. Tüm kökler ProTaper döner eğe sistemiyle apikal boyut F3 #30 olacak şekilde enstrümante edildi. 39 adet kök kanalı soğuk lateral kompaksiyon tekniği ile dolduruldu: Grup 1 n=13 : AH26+kon gütaperka. Grup 2 n=13 : EndoREZ+kon güta-perka. Grup 3 n=13 : iRoot SP+kon güta perka. Kalan 8 kök pozitif ve negatif kontrol olarak kullanıldı. Kökler 72 saat boyunca metilen mavisi solüsyonunda bekletildi ve longitudinal olarak ikiye ayrıldı. Apikal bölgedeki boya penetrasyonu steromikroskopla ölçüldü. Veriler, tek yönlü ANOVA ve post-hoc Tukey testi kullanılarak istatistiksel olarak incelendi. EndoREZ grubu istatistiksel olarak anlamlı şekilde iRoot SP’den daha fazla sızıntı gösterdi p=0.001 .

The Evaluation of Apical Microleakage of Different Root Canal Sealers

The aim of this study was to compare the apical microleakage of different root canal sealers using dye leakage method. 47 single-rooted teeth were decoronated at the cemento-enamel junction leaving a standard root length of 14 mm. All the roots were instrumented with ProTaper rotary files to an apical size of F3 #30 . The 39 root canals were obturated using cold lateral compaction as follows: Group 1 n=13 : AH26+gutta-percha. Group 2 n=13 : EndoREZ+gutta-percha. Group 3 n=13 : iRoot SP+gutta-percha. The remaining eight teeth were used as positive and negative controls. The roots were embedded in methylene blue dye solution for 72 hours and split longitudinally. Dye penetration in the apical region was measured using a stereomicroscope. The data was statistically analysed with one-way ANOVA and post-hoc Tukey tests. EndoREZ group showed statistically significantly more leakage than the iRoot SP group p=0.001
