Abstract :ABSTRACT   Objectives: The purpose of this in-vitro study was to evaluate the effect of 3-different post-space on the bond strength of fiber post. Study design: Fifty-four extracted human maxillary incisors were selected and their roots were treated endodontically. The roots were prepared according to different post spaces insert ignore into journalissuearticles values(Torpan Drill ISO 100insert ignore into journalissuearticles values(D100);, 120insert ignore into journalissuearticles values(D120); and Enapost Drill ISO 140insert ignore into journalissuearticles values(D140);, and divided into three groups. Snowposts were used, and the posts were cemented with three different dual polymerized resin luting agents: Panavia F, NX3 and Rely X. The specimens were subjected to a pullout test using a universal testing machine at a cross-head speed of 0.5 mm/min. The maximum force required to dislodge each post was recorded. Data were analyzed using the two way ANOVA and Tukey multiple comparisons tests. Results: According to the results of Tukey test, the bond strength values of the Panavia F luting cements was significantly higher in D120 post space; otherwise, there were no significant differences between Rely X and NX 3. Conclusions: It had been seen that cement thickness affects the pullout strengths of fiber-reinforced posts. Key Words: bond strength, cement thickness,  post FİBER POSTLARIN BAĞLANMA DAYANIMI ÜZERİNDE SİMAN KALINLIĞININ ETKİSİ ÖZET   Amaç: Bu çalışmanın amacı fiber postların bağlanma dayanımına 3 farklı post aralığının etkisini değerlendirmektir. Materyal ve Metod: Çekilmiş 54 adet üst kesici diş kullanıldı ve bu dişlere kök- kanal tedavisi uygulandı. Kök kanalları değişik boyutlarda post boşluklarına göre hazırlandı insert ignore into journalissuearticles values(Torpan Drill ISO 100insert ignore into journalissuearticles values(D100);, 120insert ignore into journalissuearticles values(D120); ve Enapost Drill ISO 140insert ignore into journalissuearticles values(D140);,Drill); ve 3 alt gruba ayrıldı. Fiberpostlar insert ignore into journalissuearticles values(Snowpost); 3 farklı kimyasal ve ışıkla insert ignore into journalissuearticles values(dual);sertleşen rezin simanla insert ignore into journalissuearticles values(Panavia F, NX3 and Rely X); simante edildi. Örneklere başlık hızı 0,5 mm/dk olan universal test cihazıyla çekme testi uygulandı. Postları yerinden uzaklaştıran maksimum kuvvetler kayıt edildi. Veriler Two-way ANOVA ve Tukey testleri kullanılarak analiz edildi. Bulgular: Tukey testi sonuçlarına göre Tropan D120 drill ile açılan post boşluklarında Panavia F ile simante edilen dişlerin değerlerinin en yüksek olduğu, buna rağmen Rely X ve NX3 değerleri arasında istatistiksel olarak önemli bir farklılık olmadığı görülmüştür. Sonuç: Siman kalınlığının fiberle güçlendirilmiş postların çekme kuvvetini etkilediği görülmüştür. Anahtar Kelimeler: Bağlanma Dayanımı, Siman Kalınlığı, Post
