Abstract (2. Language): 
The aim of this in vitro study was to evaluate effects of saliva contamination on microtensile bond strenght during cementation of glass fiber posts by using different adhesive materials. Thirty of one-rooted-teeth were used and divided into 6 groups (n=5). First group was cemented with using total etch adesive agent (3M Adper Single Bond), second group was cemented with using self etch adesive agent (3M Adper Prompt L-pop) and posts were cemented with dual cure resin cement. Third group was cemented by using self-etch self-adesive cement (Smart CEM Dentsply,). Forth group was cemented with using total etch adesive agent (3M Adper Single Bond), fifth group, self-etch system was contaminated with saliva and posts were cemented with dual cure resin cement. Sixth group, root canal was contaminated before self-adhesive cementation (Smart CEM Dentsply). Microtensile bond strenght tests were performed. Data were analized by Kruskall-Wallis variance analysis. Self-etch and total etch control groups (7.5 N/mm2) had showed the highest score (7.5 N/mm2) but self-adhesive control groups both contamination and control groups had showed the lowest rates (1.8 N/mm2).

Abstract (Original Language): 
Bu çalışma cam fiber post simantasyonunda farklı dental adesif ajanlarının uygulanmasının gerilme kuvvetine etkisini incelemek ve tükürük kontaminasyonunun başarı üzerine etkisini araştırmak amacıyla yapılmıştır. Çalışmada 30 adet tek köklü diş kullanılmıştır. Dişler rastgele seçilerek 6 gruba ayrılmıştır (n=5). 1.grupta total-etch, 2.grupta self-etch adesif ajanları ve her iki grupta dual cure kompozit reçine siman kullanılarak fiber postlar simante edilmiştir. 3.grupta self-etch adesif reçine siman kullanılarak fiber postlar simante edilmiştir. 4.grupta total-etch tekniği kullanılarak asit ve adesif ajan uygulamasından sonra kontaminasyon yapılıp fiber postlar kanala yerleştirilmiştir. 5.grupta self-etch tekniği kullanılarak primer ve bonding işlemlerinden sonra kontaminasyon yapılıp fiber postlar kanal yerleştirilmiştir, ö.grupta ise self adesif uygulamasından önce kontaminasyon yapılıp fiber post kanala yerleştirilip simante edilmiştir. Örneklere microtensile test cihazında gerilme kuvveti 0.5 mm/dk hızla uygulanmıştır. Verilerin istatiksel değerlendirilmesinde Kruskal Wallis analiz testi kullanılmıştır. Çıkan sonuçlarda en yüksek değeri kontaminasyon yapılmamış total-etch ve self-etch gruplarının gösterdiği (7.5 N/mm2), buna karşın self-adesif gruplarının hem kontaminasyon yapılmamış (1.8 N/mm2) hem de kontaminasyon yapılmış gruplarının (1.2 N/mm2) oldukça düşük değerler gösterdiği saptanmıştır.
