Background: In order to ensure sufficient resistance against functional forces for dentin, which is severely weakened by excessive material loss in single-root single-canal teeth with previous root canal treatment, maximum retention and resistance must be the target.

The main purpose of this study is to evaluate the shear rupture resistance of the chosen three kinds of posts placed in the teeth roots, against forces that could occur in the replicated mouth.

Methods: Freshly extracted 45 teeth -maxillary canin and maxillary central- have been used in our study. Crown portion of the tooth was removed by cutting away 1 mm over the enamel cement junction. Root canals were obturated with a lateral condensation technique using AH-26 and gutta percha sealer. In the study, 15 specimens each from Flexi-Post, Cosmopost, and FRC Postec post systems have been placed in sockets opened down through teeth by using specific burs for each system. A dual cured composite cement (Variolink II low viscosity) was used to bind posts. Prepared specimens were put in steel hose by using acrylic resin. Standardized core material (Coradent) was applied onto top side of posts, and steel hoses were connected to Lloyd test instrument with an angle of 45 degrees. A force with a speed of 1 mm/min was applied to the specimens. Compression shear rupture values were recorded and One Way ANOVA and Kruskall-Wallis variance analyses were conducted for statistical evaluation.
Results and Conclusion: Highest values were obtained in Flexi-Post group. FRC Postec was the second, and Cosmopost had the lowest strength values. However, all the systems provided adequate resistance against forces that could occur in the mouth, hence it was concluded that they can be utilized clinically.

Key words: posts and cores, post system, prefabricated post systems

Öz: Tek köklü, tek kanallı ve kanal tedavisi uygulanmış dişlerde aşırı madde kaybı nedeniyle yapısı zayıflayan dentinin fonksiyonel kuvvetlere karşı yeterli dayanıklılık gösterebilmesi için seçilecek uygun bir post sistemiyle en fazla retansiyon ve rezistans sağlamaya çalışılmalıdır.

Amaç: Bu çalışmada amaç diş köklerine yerleştirilen seçilmiş üç çeşit postun ağız içinde oluşabilecek makaslama kuvvetlerine karşı kırılma dayançlarının değerlendirilmesidir.

Gereç ve yöntemler: Çalışmamızda yeni çekilmiş 45 adet üst-kanin ve santral diş kullanılmıştır. Dişlerin kron bölümü mine-sement birleşiminin 1mm üzerinden kesilerek uzaklaştırılmıştır. Kök kanalları lateral kondensasyon tekniği ile guta perka ve AH-26 kanal dolgu maddeleri kullanılarak doldurulmuştur. Çalışmada Flexi-Post, Cosmopost ve FRC Postec post sistemlerinden 15 er adet örnek kendi drilleri kullanılarak dişlerde açılmış yuvalarına yerleştirmek suretiyle hazırlandı. Postların yapıştırılmasında dual cure kompozit bir siman olan Variolink II low viskozite kullanıldı. Hazırlanan örnekler akrilik rezin kullanılarak çelik manşet içine alındı. Postların üzerine standardize edilmiş Coradent core materyali uyglandıktan sonra manşetler 45 derece açıyla Lloyd test cihazına bağlandı. Örneklere test cihazında 1mm/dakika hızla kuvvet uygulandı. Uygulanan makaslamada kırılma testi sonucunda her örnek için kırılma kuvveti değerleri kaydedilerek istatistiksel değerlendirme yapıldı.

Sonuç: En fazla dayancı Flexi-Post gösterdi. İkinci derecede dayancı FRC Postec gösterirken en az dayancı da Cosmopost gösterdi. Ancak yapılan değerlendirmede her üç post sisteminin de ağızda oluşabilecek kuvvetlere karşı yeterli dayancı gösterebileceği ve klinik olarak da kullanılabileceği sonucuna varıldı.
