“…[35] An another study reveals that sandblasting and Er:YAG laser irradiation of the surface of the quartz fiber post before cementation provided a significant increase in bond strength between quartz fiber posts and resin cement. [36] Arslan et al [16] investigated the effects of Er:YAG laser irradiation at different parameters and the sandblasting method on the push-out bond strength of FRC posts to composite resin cores. For artificial aging, the specimens were subjected to thermal cycling.…”

“…Akin et al evaluated the bond strength of quartz fiber posts after different surface treatment methods and reported the highest bond strength in the sandblasted followed by the Er:YAG laser irradiated groups; these two methods significantly increased the bond strength of quartz fiber posts to resin cement. 35 Moreover, Kriznar et al evaluated the micro-push-out bond strength of Multicore Flow resin material to 2 types of fiber posts following Er:YAG laser irradiation, and showed that Er:YAG laser irradiation negatively affected the bond strength of resin material to fiber posts. 16 Controversial results of different studies may be attributed to factors such as type of fiber post and differences in laser parameters.…”

Introduction: This study aimed to determine the bond strength of fiber post to composite core following surface treatment with Er,Cr:YSGG laser at different powers and sandblasting with and without thermocycling. Methods: In this experimental study, 30 fiber posts (Glassix, Nordin, Switzerland) were randomly divided into 5 groups of sandblasting, no treatment and laser irradiation at 1, 1.5 and 2 W powers. Following composite filling and mounting, 1-mm thick sections were made for pushout bond strength testing. Half of the samples in each group were subjected to thermocycling (n=15). Two-way analysis of variance (ANOVA) was used to analyze the bond strength values. Pairwise comparisons were made using Tukey test (P < 0.05). Results: Effect of treatment method on push-out bond strength of fiber post to composite core was significant (P = 0.017), while thermocycling had no significant effect on bond strength (P = 0.964). Pairwise comparison of surface treatment methods revealed no significant difference in groups with and without thermocycling (P > 0.05), but Er,Cr:YSGG laser irradiation with 1 W power yielded significantly higher bond strength than the control group (P =0.01). Conclusion: Irradiation of Er,Cr:YSGG laser at 1 W power increased the bond strength of fiber post to composite core. Thermocycling slightly decreased the bond strength at the fiber postcore interface.

Bu çalışmanın amacı, farklı parametrelerdeki fiber lazer ile yüzey pürüzlendirme işlemlerinin, titanyum ve rezin siman arasındaki bağlanma dayanımı üzerindeki etkisini araştırmaktır. Gereç ve Yöntem: Döküm, CAD/CAM ve lazer sinterleme yöntemleriyle 3 farklı şekilde üretilmiş, 90 adet titanyum örneği hazırlandı (n=30). Tüm bağlanma yüzeyleri standardizasyonu sağlamak amacıyla, sırasıyla 600-1000-1200 partiküllü silikon karbid kağıtlarla cilalama yapıldı ve her örneğin yüzey pürüzlülüğü ölçüldü. Her grup 3 alt gruba ayrıldı (n=10): grup (1) 110 mµ Al 2 O 3 partikülleri ile kumlama, grup (2) fiber lazer 10 W, grup (3) fiber lazer 20 W. Yüzey işlemleri tamamlanan örneklerin bağlanma yüzeylerine metal primer ve dual-cure self adeziv rezin siman uygulandı. Polimerizasyonu tamamlanan örnekler kalıptan çıkartıldı ve tesviyesi yapıldı. Örneklerin kırılma işlemi üniversal test cihazında 1 mm kalınlığındaki kesme bıçağı ile yapıldı. Verilerin istatistiksel analizinde titanyum tipi ve pürüzlendirme şeklinin bağlanma dayanımı üzerindeki ortak etkisinin değerlendirilmesinde Two way Anova testi kullanıldı. Devam testi olarak One way Anova Test kullanıldı. Anlamlılık p<0,05 düzeyinde değerlendirildi. Bulgular: Tüm titanyum tiplerinde kumlama işleminin, 20 W gücündeki fiber lazer uygulamasına kıyasla daha yüksek bağlanma dayanımı oluşturduğu görüldü (p<0,05). 10 W gücündeki fiber lazer uygulaması ile kumlamaya yakın bağlanma dayanımı değerleri elde edildi. Kumlama işlemi uygulanan gruplarda, CAD/CAM grubunun ortalama bağlanma dayanımı (6,42 MPa), Döküm (12,61 MPa) ve Lazer Sinter (11,27 MPa) gruplarından anlamlı derecede düşük bulundu (p<0,05). Sonuç(lar): Titanyum-rezin siman bağlanmasında en etkili yüzey pürüzlendirme yönteminin kumlama olduğu, düşük güçte (10W) fiber lazer uygulaması ile yüksek güce kıyasla (20W) daha başarılı bir bağlanma elde edildiği sonucuna varıldı.
