Amaç: Bu in vitro çalışmada Mikrohibrid doldurucu içeriği ile yeni geliştirilen bir dental kompozitin mekanik özelliklerinden bükülme dayanımının iki farklı mikrohibrit dolduruculu kompozit materyal ile karşılaştırılmalı olarak değerlendirilmesi amaçlanmıştır.
Gereç ve Yöntem: Mevcut çalışmada, yeni üretilen bir Üniversal Kompozit (Dolgunn, Himg Seramik ve Medikal Kompozit San.Tic. Ltd.Sti, Türkiye) ile 2 farklı mikrohibrit kompozit (G- aenial Anterior, GC-Japonya ve Filtek Z250 3M, USA) kullanıldı. Her bir dolgu materyalinden 10 adet dikdörtgenler prizması şeklinde (2x2x25 mm boyutunda) örnekler hazırlanarak, instron test cihazında 1 mm/dk hızda bükülme dayanım değerleri ölçüldü. Verilerin istatistiksel analiz için Kruskal-Wallis testi kullanıldı. Tüm testler için istatistiksel anlamlılık düzeyi p=0.05 alındı.
Bulgular: Tüm test materyalleri arasında bükülme dayanımları açısından istatistiksel olarak anlamlı farklılıklar gözlendi (p<0.05). En yüksek bükülme dayanımı değerini Filtek Z250 gösterirken en düşük bükülme dayanım değerini G-aenial materyali göstermiştir. G-aenial ve Dolgunn materyalleri arasında istatistiksel olarak anlamlı farklıklar bulunmazken; her iki materyal ile Filtek Z250 arasında istatistiksel olarak anlamlı farklılık bulunmuştur.
Sonuç: Çalışma sonuçlarına göre yeni geliştirilmiş olan Dolgunn kompozit dolgu materyali değerlendirilen diğer mikrohibrit kompozitlerden birinden daha yüksek ancak yakın diğerinden daha düşük değerlerde bükülme dayanımı değerleri göstermiştir. Kullanılan tüm materyallerin öngörülen standartların üzerinde bükülme dayanım değerlerine sahip oldukları görülmüştür. Yeni geliştirilen formülasyona sahip kompozit materyalinin daha kapsamlı mekanik testler ile değerlendirilmesi yönünde öncü bir çalışma olacağı düşünülmektedir.

Aim: In this in vitro study, it was aimed to evaluate the mechanical properties of a newly developed dental composite material with microhybrid filler content and its flexural strength comparatively with two different microhybrid filler composite materials.
Material and Methods:
In the current study, the newly produced Universal Composite filling material (Dolgunn, Himg Seramik ve Medikal Kompozit San.Tic. Ltd.Sti, Turkey) and 2 different microhybrid composite materials (G-aenial Anterior, GC-Japan and Filtek Z250 3M, USA) were used. Ten rectangular prisms (2x2x25 mm in size) samples were prepared from each filling material, and the bending strength values were measured at a speed of 1 mm/min in an instron test device. Kruskal-Wallis test was used for statistical analysis of the data. Statistical significance level was taken as p=0.05 for all tests.
Results: Differences were observed between the materials in terms of flexural strengths (p<0.05). Filtek Z250 showed the highest flexural strength value, while G-aenial material showed the lowest value. While there was no statistically significant difference between G-aenial and Dolgunn materials, a difference was found between both materials and Filtek Z250.
Conclusion: According to the results of the study, the newly developed Dolgunn composite filling material showed higher flexural strength values than one of the other microhybrid composites evaluated but lower than the other close ones. It has been observed that all materials used have flexural strength values above the prescribed standards. It is thought that it will be a pioneering study in the evaluation of the newly developed composite material with more comprehensive mechanical tests.
