Abstract

Aim: The aim of this study was to evaluate the flexural strength, microhardness, water sorption and solubility of different composite resins polymerized with direct and indirect polymerization techniques. Materials and Methods: Three composit resines, classified according to their resin matrix, were selected: U200 (3M ESPE), Grandio (VOCO), Xtrafil (VOCO). Composite resins were divided into three subgroups according to polymerization technique: LED (Eliapar, 3M ESPE), LED + indirect light (DI 500 Coltene), indirect light +heat + pressure (Tescera ATL, Bisco Dental). Seven rectangular specimens (25mmx2mmx2mm) of each subgroup were prepared and 3-point bending tests were performed for flexural strength values. To determine Vickers hardness, water sorption and solubility tests; seven cylindrical specimens (diameter: 8mm thickness: 2mm) were prepared. The cylindrical specimens were stored in distilled water for 24 hours at 37◦C, and the microhardness values were measured with a Vickers hardness tester. Then, specimens were stored in the same conditions for 24 hours and water sorption values were measured. The same specimens were kept in desiccators and dried for solubility measurements until constant mass was achieved. Data were analyzed by two-way ANOVA and Tukey's post-hoc test (α=0.05). Results: The interaction between polymerization techniques and composite resins was significant only in flexural strength values (p

Özet

Amaç: Bu çalışmanın amacı, direkt veya indirekt polimerizasyon teknikleri ile polimerize edilmiş farklı kompozit rezinlerinmikrosertlik, bükülme dayanımı, su emilimi ve çözünürlüklerini değerlendirmektir.Materyal ve Metot: Rezin matriksine göre sınıflandırılan 3 kompozit rezin seçildi: U200 (3M ESPE), Grandio (VOCO), Xtrafil(VOCO). Kompozit rezinler polimerizasyon tekniğine göre üç alt gruba ayrıldı: LED (Eliapar, 3M ESPE), LED+ indirekt ışık (DI 500Coltene) , indirekt ışık+ısı+basınç (Tescera ATL, Bisco Dental). Her bir alt grup için yedi dikdörtgen örnek (25mm x 2mm x2mm) yapıldı ve bükülme dayanım değerleri için üç nokta büküm testleri yapıldı. Vickers sertliğini, su emme derecesini veçözünürlüğünü belirlemek için yedi silindirik örnek (çap: 8mm, kalınlık: 2mm) yapıldı. Silindirik örnekler 37 ° C'de 24 saatboyunca distile suda saklandı ve mikrosertlik değerleri bir Vickers sertlik test cihazı ile ölçüldü. Su emilim testi için hazırlananörnekler 24 saat aynı koşullarda depolandı ve su emme değerleri ölçüldü. Aynı örnekler desikatörde sabit kütle elde edilinceyekadar kurutuldu ve çözünürlük ölçümleri yapıldı. Veriler iki yönlü ANOVA ve Tukey's post-hoc testi (α = 0.05) ile analiz edildi.Bulgular: Polimerizasyon teknikleri ile kompozit rezinler arasındaki etkileşim yalnızca bükülme dayanım değerlerinde anlamlı idi(p
