Abstract

Purpose: The aim of this in vitro study was to compare the microleakage of two fiber-reinforced post systems cemented with luting agents that utilize two currently available adhesive approaches in three segments of teeth. Materials and Methods: Forty two extracted human maxillary central incisor and canine teeth with straight root canals were prepared using a step-back technique and obturated with gutta-percha using lateral condensation. Following standardized post-space preparations, the roots were divided into 2 fiber-post groups (Carbopost, RelyX Fiber Post) and further divided into 3 subgroups of 7 specimens each for the adhesive approach (Panavia F, RelyX Unicem, Maxcem). All specimens were thermal cycled 2500 times between 5°C and 55°C and stored in methylene-blue solution for 24 hours. Bonded specimens were cut horizontally into three sections (Cervical, Medium, Apical) and each section was evaluated using a stereomicroscope at original magnification X12. For each image, dye penetration was estimated as the ratio of methylene-blue-infiltrated surface divided by total dentin surface. The data were statistically analyzed by using the Kruskal-Wallis test and Mann-Whithney U test (p

Özet

Amaç: Bu in vitro çalışmanın amacı güncel adeziv yaklaşımla simante edilen fiber post sistemlerin dişin üç ayrı bölgesindeki mikrosızıntılarının karşılaştırılmasıdır. Gereç ve yöntem: 42 adet düz kök yapısına sahip üst santral ve kanin dişler step-back tekniği ile genişletilip lateral kondensasyon ile güta-perka kullanılarak dolduruldu. Standard post preparasyonlarını takiben hazırlanan kökler iki farklı fiber post gruplarında kullanılmak üzere ayrıldı ve her bir adeziv siman grubu için (Panavia F 2.0, RelyX Unicem, Maxcem) 7 örnek olacak şekilde üç alt gruba ayrıldı. Örnekler 2500 kez (555 C) termal siklus işleminden geçirildi sonrasında 24 saat metilen mavisi solüsyonunda saklandı. Simante edilen örneklerden yatay olarak 3 er kesit elde edildi (Sevikal, Orta, Apikal) ve her bir kesit stereo mikroskop altında X12 büyütmede incelendi. Mikrosızıntı, boyanan dentin yüzeylerinin tüm dentin yüzeyine oranlanması ile elde edildi. Veriler Kruskal-Wallis ve Mann-Whitney U testleri kullanılarak istatistiksel olarak 0.05 anlamlılık düzeyinde değerlendirildi. Bulgular: Karbon fiber postlar, cam fiber postlara göre servikal kök kesitlerinde istatistiksel olarak anlamlı derecede daha yüksek mikrosızıntı göstermiştir (p
