Özet:

 Background: The aim of this study is to investigate the surface roughness and colour changes of different types of acrylic resins after soaking in different liquids and after cleaning with denture cleaning tablet. Methods: Disc-shaped specimens were obtained from three different acrylic resins heat polymerised Meliodent, autopolymerised Meliodent, microwave polymerised Acron MC n20, each group. Each acrylic resin was divided into 4 subgroups distilled water, tea, coffee, cola according to the type of liquids n5 and kept in the respective solutions for 48 hours. Afterwards, the specimens in each subgroup were kept in denture cleaning tablet solution Corega for 64 hours. Surface roughness and colour values of the samples were measured at the beginning, 48 hours and 64 hours. Surface roughness and colour change values were examined by three-way analysis of variance ANOVA. The relationship between roughness and colour change values was examined by Pearsons correlation coefficient p0,05. Results: Surface roughness values were affected by liquid type p0,008, method p0,001, time p0,001 and methodtime interaction p0,001. Colour change values were affected by liquid type p0,012, method p0,001, time p0,001 and liquid typemethodtime interaction p0,001. There was no significant correlation between roughness and colour change values of all groups. Conclusion: Colouration of acrylic base materials after soaking in cola and tea was found to be higher than coffee. The colour change after soaking in the denture cleaning solution is especially high in coffee. The highest roughness values were observed in autopolymerised acrylic resins. Alkaline peroxide cleaning solution can be recommended for chemical cleaning of acrylic resins, but it should be taken into consideration that it may increase surface roughness in base materials. Keywords: Prosthesis base materials, Colour stability, Surface roughness.

 Amaç: Farklı tip akrilik rezinlerin farklı sıvılarda bekletme sonrası ve protez temizleme tableti ile temizleme sonrası yüzey pürüzlülük ve renk değişiminin incelenmesidir. Gereç ve Yöntemler: Üç farklı akrilik rezinden ısı ile polimerize Meliodent, otopolimerize Meliodent, mikrodalga ile polimerize Acron MC disk şeklinde örnekler elde edildi. n20, her bir grup Her bir akrilik rezin bekletileceği sıvı tipine göre kendi içinde 4 alt gruba distile su, çay, kahve, kola ayrıldı n5 ve ilgili sıvılarda 48 saat bekletildi. Sonrasında her bir alt grupta yer alan örnekler protez temizleme tablet solüsyonunda Corega 64 saat boyunca bekletildi. Örneklerin yüzey pürüzlülük ve renk değerleri başlangıçta, 48 saat ve 64 saat sonunda ölçüldü. Yüzey pürüzlülük ve renk değişim değerleri 3 yönlü varyans analizi ANOVA ile incelendi. Pürüzlülük ve renk değişim değerleri arasındaki ilişki Pearson kolerasyon katsayısı ile incelendi. p0.05 Bulgular: Yüzey pürüzlülük değerleri sıvı tipi p0.008, yöntem p0,001, zaman p0,001 ve yöntemzaman etkileşiminden p0.001 etkilenmiştir. Renk değişim değerleri sıvı tipi p0.012, yöntem p0.001, zaman p0.001 ve sıvı tipiyöntemzaman etkileşiminden p0.001 etkilenmiştir. Tüm grupların pürüzlülük ve renk değişim değerleri arasında anlamlı bir kolerasyon bulunamamıştır. Sonuç: Akrilik kaide materyallerinde kola ve çayda bekletme sonrası renklenme kahveden daha fazla bulunmuştur. Protez temizleme solüsyonunda bekletme sonrası renk değişimi özellikle kahvede daha yüksektir. Otopolimerize akrilik rezinlerde en yüksek pürüzlülük değerleri gözlenmiştir. Alkalen peroksit temizleme solüsyonu, akrilik rezinlerin kimyasal temizliği için önerilebilir ancak kaide materyallerinde yüzey pürüzlülüğünü arttırabileceği dikkate alınmalıdır.
