Amaç: Bu araştırmanın amacı, sonik enerji ile aktive edilen nano hibrit bulk-fill kompozit rezinin (SonicFill) cam iyonomer esaslı materyallere makaslama bağlanma dayanımını değerlendirmektir. Yöntem: Araştırmamızda 4 mm çapında ve 2 mm derinlikte silindirik boşlukları bulunan 26 adet akrilik blok hazırlandı ve kullanılan cam iyonomer esaslı materyale göre rastgele iki gruba (n=13) ayrıldı geleneksel cam iyonomer siman ve rezin modifiye cam iyonomer siman. Üretici firmaların talimatlarına göre hazırlanan cam iyonomer simanlar akrilik bloklardaki boşluklara yerleştirildi. Adeziv işlemlerin ardından, cam iyonomer simanların üzerine 2.3 mm çapında ve 3 mm yüksekliğinde silindirik plastik kalıplar yardımıyla SonicFill uygulandı ve ardından ışıkla polimerize edildi. Tüm örnekler 24 saat nemli ortamda bekletildikten sonra makaslama bağlanma dayanım değerleri universal test cihazı kullanılarak ölçüldü. Elde edilen verilerin istatistiksel analizinde bağımsız iki örnek T testi kullanıldı. Bulgular: Ortalama makaslama bağlanma dayanımı ve standart sapma değerleri geleneksel cam iyonomer grubunda 10.52 ± 1.63, rezin modifiye cam iyonomer siman grubunda ise 14.85 ± 1.79 olarak tespit edildi. Gruplar arasında makaslama bağlanma dayanımı açısından istatistiksel olarak anlamlı bir fark olduğu saptandı (p<0.05). Sonuç: İn vitro olarak yapılan bu araştırmanın sınırlamaları dahilinde, sonik enerji ile aktive edilen nano hibrit bulk-fill kompozit rezinlerin altında cam iyonomer siman kullanılacağı zaman geleneksel cam iyonomer simandan daha yüksek makaslama bağlanma dayanımına sahip olan rezin modifiye cam iyonomer simanların kullanılması tercih edilebilir. Bununla birlikte, bu in vitro araştırmanın bulgularını destekleyecek gelecek klinik çalışmalara ihtiyaç vardır.
Objective: The aim of this study was to evaluate the shear bond strengths of sonic activated nano hybrid bulk-fill composite resin to glass ionomer-based materials. Materials and Methods: 26 cylindrical acrylic blocks with a hole in the middle measuring 4 mm diameter and 2 mm height were prepared and divided into two groups (n=13) according to the materials used; conventional glass ionomer cement and resin modified glass ionomer cement. The hole was filled with conventional glass ionomer cement and resin modified glass ionomer cement according to manufacturer's instructions. After adhesive procedures, SonicFill was applied upon glass ionomer cements with the help of cylindrical plastic mold (2.3 mm in diameter and 3 mm in height) then light cured. All specimens were stored for 24 h in a moist environment and then shear bond strength was measured by universal testing machine. Data were analyzed using Independent- Samples T-test. Results Means and standard deviations of shear bond strength values were recorded for conventional glass ionomer cement as 10.52 ± 1.63 and 14.85 ± 1.79 MPa for resin modified glass ionomer cement. Statistically significant differences in shear bond strength were observed among groups (p<0.05). Conclusion Within the limitations of the present study, a resin modified glass ionomer cementwhich exhibited significantly higher shear bond strength than conventional glass ionomer cement-could be preferred choice when placing glass ionomer materials under sonic activated nano hybrid bulk-fill composite resin. However, further clinical research is needed to confirm the findings of this in vitro study.
