ABSTRACT
Objective: The aim of this study was to evaluate the effect of an injectable pozzolan-based root canal sealer in combination with RetroMTA on fracture resistance of simulated immature teeth. Material and Methods: Fifty-five mandibular premolars were used. Roots were cut from the cemento-enamel junction and Access cavities were prepared. Working lengths were determined and the canals were instrumented using Reciproc system up to R40 instrument. Peeso reamers (No. 1-6) were used, and the Peeso reamer no. 6 was stepped out from the apex to simulate an incompletely formed root. Specimens were distributed into five groups according to the filling techniques (n=11): Group 1: Negative control, Group 2: EndoSeal MTA, Group 3: RetroMTA, Group 4: Apical plug with RetroMTA + backfill with EndoSeal MTA, Group 5: Apical plug with RetroMTA + backfill with thermoplasticized gutta-percha and EndoSeal MTA. All roots were embedded in the acrylic blocks. A vertical fracture compression test was applied with a universal testing machine at a crosshead speed of 1 mm/min. The fracture loads were recorded for each tooth, and statistical interpretations were made by using SPSS 20.0 (α=0.05). Results: There are statistically significant differences among the groups (p<0.05). The mean values of Group 2 showed the highest results (835±278.53 N). The lowest mean values were in Group 1 (507.663±151.732 N). Conclusions: Considering the results of our study, it can be said that filling the root canals with MTA products in immature teeth contributes positively to the fracture resistance of the roots.

ÖZET
Amaç: Bu çalışmanın amacı, enjekte edilebilir bir pozzolan bazlı kök kanal patının, RetroMTA ile kombinasyon halinde simüle edilmiş apeksi açık dişlerin kırılma direncine etkisini değerlendirmektir. Gereç ve Yöntemler: Çalışmamızda 55 alt küçük azı diş kullanıldı. Dişlerin kronları ve kökleri mine sement birleşiminden ayrıldı ve kök kanal boşlukları şekillendirildi. Çalışma uzunlukları belirlenmiş ve kanallar Reciproc sistemi kullanılarak R40 alete kadar genişletildi. Apeksi açık dişleri simüle edebilmek için, Peeso no.6 ile köklerin dışına çıkıldı. Örnekler, doldurma tekniklerine göre beş gruba dağıtıldı (n = 11): Grup 1: Negatif kontrol, Grup 2: EndoSeal MTA, Grup 3: RetroMTA, Grup 4: RetroMTA+Apikal dolgu, EndoSeal MTA, Grup 5: Termoplastik gutta-percha ve EndoSeal MTA ile RetroMTA + apikal dolgu. Tüm kökler akrilik bloklara gömüldü. Üniversal test cihazı ile 1 mm /dak hızında kompresyon kırma testi uygulandı. Her diş için kırılma yükleri kaydedildi ve SPSS 20,0 (α=0,05) kullanılarak istatistiksel analizler yapıldı. Bulgular: Gruplar arasında istatistiksel olarak anlamlı farklılık olduğu tespit edildi (p<0,05). Grup 2'nin ortalama değerleri en yüksek sonuçları gösterdi (835±278,53 N). En düşük ortalama değerler Grup 1'de tespit edildi (507,663±151,732 N). Sonuç: Çalışmamızın sonuçları göz önüne alındığında immatür dişlerde kök kanallarının MTA içerikli ürünlerle doldurulmasının köklerin kırılma direncine olumlu yönde katkı sağladığı söylenebilir.
