Abstract

Aim: The aim of this study was to evaluate the shear bond strength of pretreated dentin with various Erbium:yittrium-aluminum-garnet (Er:YAG) laser energy densities to core composite. Material and Methods: Fifty intact inferior permanent first molar teeth were ground to produce a flat dentin surface and randomly divided into 5 groups according to the surface treatments (n=10); control: no surface treatment, group L1: 100 mJ Er:YAG laser irradiation, group L2: 150 mJ Er:YAG laser irradiation, group L3: 200 mJ Er:YAG laser irradiation, group L4: 300 mJ Er:YAG laser irradiation. Following the surface treatments, one specimen of each group were examined by scanning electron microscopy (SEM). Then, universal bonding agent was applied to all treated dentin surface and core composite was built up by using a 2×3 mm cylindrical teflon mold. All specimens were subjected to thermal cycling before the shear bond strength test by universal testing machine. The data were analyzed by using one-way ANOVA and Tukey HSD tests for the comparison of mean shear bond strength values. Results were considered significant for α=0.05. Results: Group L1 (10.48 ± 1.58 MPa) and group L2 (9.76 ± 1.01 MPa) showed significantly higher shear bond strength values than the other groups (p

Özet

Amaç: Bu çalışmanın amacı, farklı enerji yoğunluğundakiErbium:yittrium-aluminum-garnet (Er:YAG) lazerile pürüzlendirilen dentin ile kor kompoziti arasındakimakaslama bağlanma dayanımını değerlendirmektir.Gereç ve Yöntem: 50 adet sağlam daimi alt 1. azıdişinin oklüzal yüzleri aşındırılarak düzgün bir dentinyüzeyi elde edildi ve uygulanacak yüzey işlemlerinegöre rastgele 5 gruba ayrıldı (n=10); kontrol: herhangibir yüzey işlemi uygulanmadı, Grup L1: 100 mJEr:YAG lazer uygulandı, Grup L2: 150 mJ Er:YAGuygulandı, Grup L3: 200 mJ Er:YAG uygulandı ve GrupL4: 300 mJ Er:YAG lazer uygulandı. Yüzey işlemlerinitakiben her gruptan birer örnek taramalı elektronmisroskobu (SEM) kullanılarak incelendi. Elde edilendentin yüzeylerine üniversal bağlayıcı ajan ve 2×3 mmsilindirik teflon kalıp yardımı ile kor kompoziti uygulandı.Kor kompoziti uygulanan örneklere ısısal döngüuygulandıktan sonra makaslama bağlanma dayanımıüniversal test cihazı kullanılarak ölçüldü. Sonuçlarınistatistiksel analizi tek yönlü ANOVA ile yapıldı vesonrasında Tukey HSD testi kullanılarak gruplara aitortalamalar karşılaştırıldı. Sonuçlar α=0.05 için anlamlıkabul edildi.Bulgular: Grup L1 (10.48 ± 1.58 MPa) ve Grup L2(9.76 ± 1.01 MPa), diğer tüm gruplara göre istatistikselolarak anlamlı şekilde daha yüksek makaslamabağlanma dayanımı değerleri gösterdi (p
