- W2953574373 abstract "Amaç: Bu orijinal araştırmanın amacı, kök duvarlarında Er:YAG lazer kullanımının, oval kök kanallarında açılan post boşluklarına özel olarak Bilgisayar Yardımıyla Tasarım / Bilgisayar Yardımıyla Üretim ( CAD/CAM) teknolojisiyle hazırlanan zirkonyum postların push-out bağlanma dayanımına etkisini değerlendirmektir. Gereç ve Yöntemler: Çalışmaya yapılan radyolojik muayene sonucunda seçilen, oval kök kanal konfigürasyonuna sahip 40 diş dahil edildi. Kök kanal tedavisinin tamamlanmasının ardından ultrasonik uçlarla post boşluğu hazırlandı. Örnekler rastgele şekilde, post boşluğu duvarlarına Er:YAG uygulanıp uygulanmamasına göre iki gruba ayrıldı (n=20). Her bir örnek için post boşluğunun taranmasıyla freze cihazıyla eksiltme yöntemi ile yttria stabilize tetragonal zirkonyum polikristal (Y-TZP) bloklarından zirkonya postlar üretildi. Postlar sinterlendikten sonra simante edildi. Push-out bağlanma testi uygulandı ve elde edilen veriler t-testi ile chi-square testi kullanılarak istatistiksel olarak değerlendirildi. Bulgular: Kök kanal duvarlarına Er:YAG lazer uygulaması yapılmış olan grubun push-out bağlantı değerleri, lazer uygulamayan gruba göre anlamlı oranda yüksek bulunmuştur (p<0.05). Sonuç: Radiküler dentine Er:YAG lazer uygulaması push-out bağlanma değerlerini arttırmıştır. Anahtar kelimeler: Endodonti, diş restorasyonu, zirkonyum post, Er:YAG lazer The Effect of Er:YAG Laser Preatreatment of Radicular Dentin on the Push-out Bond Strength of CAD/CAM Fabricated Milled Zirconia Posts in Oval Root Canals Abstract Aim: This original research study aimed to evaluate the effect of Er:YAG laser irradiation of post spaces prepared in oval root canals on the push-out bond strenght of zirconia posts manufactured by Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) technology. Materials and methods: Forty teeth showing oval root canal configuration were included to the study following the radiological examination. Post spaces were prepared with ultrasonic tips after the completion of root canal treatment. Specimens were divided into two groups randomly either they were irradiated with Er:YAG lasers or not (n=20). For each specimen, zirconium posts were produced by milling from yttria-tetragonal zirconia polycrystal (Y-TZP) blocks. Posts were sintered and luted in the post spaces of specimens. Push-out bond strenght test was performed and data was statistically analyzed using t-test and chi-square test. Results: The push-out bond strenght values of the group, which specimens were irradiated with Er:YAG laser were significantly higher when compared to non-lased group (p<0.05). Conclusion: Er:YAG laser pretreatment of radicular dentin improved the push-out bond strenght values. Key Words: Endodontics, dental restoration, zirconium posts, Er:YAG laser" @default.
