Protez temizleyicilerinin protez astar materyallerinin yüzey özelliklerine etkisi

Amaç: Çalışmanın amacı, yumuşak ve sert protez astar materyallerinin yüzey pürüzlülüğü ve serbest yüzey enerjisi üzerinde, farklı protez temizleyicilerinin etkisini değerlendirmektir. Materyal ve Metod: Altı farklı protez astar materyali (akrilik ve silikon yumuşak astarlar ve sert astar materyalleri) seçildi. Disk şeklinde örnekler hazırlandı ve yüzey pürüzlülük değerleri için bir profilometre kullanıldı. Üç referans sıvının temas açıları örnek yüzeylerinde ölçüldü ve yüzey enerji parametreleri asitbaz teorisine göre hesaplandı. Örnekler distile suda ve çeşitli protez temizleyicilerinde (Corega, Fitty Dent, Klorheksidin), bir aylık test süresi boyunca günde 8 saat süreyle bekletildi. Bir aylık depolamadan sonra, yüzey pürüzlülüğü ve yüzey serbest enerjisi için son ölçümler yapıldı. Veriler, Bonferroni düzeltmeli Wilcoxon Signed Rank testleri, Kruskal-Wallis testi ve iki yönlü ANOVA kullanılarak istatistiksel olarak analiz edildi. Bulgular: Protez temizleyicilerinde bekletmeden önce ve sonra yüzey pürüzlülüğü değerleri arasında anlamlı fark yoktu (p> 0.05). Distile suyun yüzey pürüzlülüğüne etkisi diğer protez temizleyicilerine göre anlamlı olarak daha düşüktü (p

The effect of denture cleaners on the surface properties of denture lining materials

Aim: The aim of the study is to evaluate the effect of different denture cleaners on the surface roughness and surface free energy of soft and hard denture lining materials. Materials and Method: Six different denture lining materials (hard liners, acrylic and silicone soft liners,) were selected. Disc shaped specimens were prepared, a profilometer was used for surface roughness values. The contact angles of three reference fluids were measured at the surface of the specimens, the surface free energy was calculated according to the acid-base theory. The samples were kept in distilled water and various denture cleansers (Corega, Fitty Dent, Clorhexidine) for 8 hours a day. After one month of storage, final measurements were made. The data was analyzed by Wilcoxon Signed Rank tests with Bonferroni correction, Kruskal-Wallis test, two-way ANOVA. Results: There was no significant difference between baseline and after immersion in denture cleaners for surface roughness values (p> 0.05). The effect of distilled water on surface roughness was significantly lower than other denture cleaners (p
