Amaç: Bu çalışmada, retreatment sırasında GuttaSolv kullanımının, iki farklı fiber post sisteminin (D.T. Light-Post/ Duolink dual-cure rezin siman ve RelyX post/ RelyX Unicem self-adheziv rezin siman) bağlanma dayanımlarına etkisini pull-out testi ile analiz edilmesi amaçlanmıştır.Gereç ve Yöntemler: Çalışmaya 40 adet çekilmiş insan alt çene küçük azı dişi dahil edildi. Kök kanallarının şekillendirilmesi ve doldurulmasının ardından, örnekler retreatment protokolüne göre rastgele dört gruba (n=10) ayrıldı. 1. ve 3. gruplarda dolgu materyali sadece ProTaper Reteratment sistemi kullanılarak çıkarılırken, 2. ve 4. gruplarda çıkarma işlemi sırasında ek olarak GuttaSolv çözücüsü uygulandı. Daha sonra kanallar yeniden dolduruldu. 1. ve 2. gruplarda RelyX U200 Automix self-adeziv rezin siman sistemi kullanılarak RelyX fiber postlar yerleştirildi. 3. ve 4. gruplarda ise D.T. Light fiber postlar All-Bond Universal ve Duo-Link rezin siman ile simante edildi. Kökler, üniversal test makinesine bağlı bir çekme test cihazına monte edildi. Postun kökten ayrıldığı anda kaydedilen maksimum kuvvet, bağ kopma değeri olarak tanımlandı.Bulgular: Çekme testi, gruplar arasında istatistiksel olarak anlamlı farklılıklar olduğunu gösterdi (p=0.001, p

Objectives: This study evaluated whether the use of the gutta-percha solvent Guttasolv during retreatment procedures influences the retention of two fiber post systems: D.T. Light-Post used with Duolink dual-cured luting resin cement and RelyX posts used with RelyX Unicem self-adhesive resin cement.Materials and Methods: Forty extracted human mandibular premolars were included in the study. After the preparation and obturation of the root canals, the specimens were randomly assigned to four groups (n=10) according to the retreatment protocol. In Groups 1 and 3, the filling material was removed using only the ProTaper Retreatment system, whereas in Groups 2 and 4 the solvent GuttaSolv was additionally applied during the removal procedure. Afterward, the canals were re-obturated. RelyX fiber posts were placed in Groups 1 and 2 using the RelyX U200 Automix self-adhesive resin cement system. In Groups 3 and 4, D.T. Light fiber posts were cemented with All-Bond Universal and Duo-Link resin cement. The roots were mounted in a pull-out testing device connected to a universal testing machine. The maximum force recorded at the moment the post was dislodged from the root was defined as the bond failure value. Results: The pull-out test demonstrated statistically significant differences among the groups (p=0.001, p
