Abstract

Aim: The aim of the present study was to assess the effect of the exposure to food-simulating liquids on the surface roughness (SR) of five restorative materials.

Materials and  Methods: Admira Fusion X-tra (AFX), Ceram X One (CRX), Gradia Indirect (GRA), Filtek P60 (P60) and Lava Ultimate (LAV) were used in the study. Thirty specimens of each material were prepared, stored for 24 h in distilled water. Then all specimens finished and polished with Sof-Lex discs. The initial SR of all samples was measured with a profilometer (Surftest SJ-201, Mitutoyo). All specimens of each composite were randomly allocated to 4 groups (n=6), according to the food-simulating liquid in which they were immersed for 30 days at room temperature and dark environment: distilled water, citric acid (0.02 N), ethanol (%75) and HCl (pH 1.2). Solutions were replaced weekly. Repeated SR measurements were performed at 30 day storage time. ΔRa values were obtained by subtracting the first measurement from the last measurement. Data were analysed by one-way ANOVA followed by Tukey’s HSD test (p=0.05).

Results: In ethanol-water immersion, the ΔRa value in the GRA was statistically different from the CRX and P60 (p<0.05). When the ΔRa values obtained in the stored of citric acid were examined, only AFX increased statistically compared to the other groups (p<0.05). There was no statistically significant difference in the ΔRa values between the materials that immersion in distilled water and HCL.

Conclusion: The SR of the evaluated composite resins was affected differently from their immersion in food-stimulating media.

Besinleri Ve Ağız Ortamını Taklit Eden Sıvıların Restoratif Materyallerin Yüzey Pürüzlülüğüne Etkisi

Abstract

Amaç: Bu çalışmanın amacı, 5 farklı restoratif materyalin ağız ortamını taklit eden sıvılarda bekletil¬mesinin yüzey pürüzlülüğü (SR) üzerine etkilerini değerlendirmektir.

Gereç ve Yöntemler: Çalışmada kullanılan materyaller Admira Fusion X-tra (AFX), Ceram X One (CRX), Gradia İndirekt (GRA), Filtek P60 (P60) ve Lava Ultimate’tir (LAV). Her materyalden 30 adet örnek hazırlandı ve örnekler 24 saat distile suda bekletildi. Tüm örneklere Sof-Lex seti kul¬lanılarak bitim ve cila işlemi uygulandı. Ardından tüm örneklerin başlangıç yüzey pürüzlülüğü bir profilometre cihazı (Surftest SJ-201, Mitutoyo) ile ölçüldü. Her materyal grubuna ait örnekler farklı solüsyonlarda bekletilmek üzere 4 alt gruba ayrıldı (n=6): Distile su, sitrik asit (0,02 N), etanol (%75) ve hidroklorik asit (HCl) (pH 1,2). Örnekler karanlık ortamda oda sıcaklığında 30 gün boyunca so¬lüsyonlarda bekletildi. Solüsyonlar haftalık olarak yenilendi. Otuz gün sonunda pürüzlülük ölçümleri tekrar yapıldı. Son ölçümden ilk ölçüm çıkarılarak ΔRa değerleri elde edildi. Veriler tek yönlü ANOVA ve ardından Tukey HSD testi ile analiz edildi (p=0,05).

Bulgular: Etanol-su çözeltisinde bekletilen materyaller arasında, GRA grubundaki ΔRa değerinin, CRX ve P60 grubuna kıyasla istatistiksel olarak anlamlı bir farklılık gösterdiği (p<0,05) bulundu. Sit¬rik asitte bekletilen örneklerin ΔRa değerleri incelendiğinde ise sadece AFX grubunda diğer grup¬lara göre istatistiksel olarak anlamlı artış gözlendi (p<0,05). Distile su ve hidroklorik asitte bekletilen bütün materyal grupları arasında ΔRa değerlerinde istatistiksel olarak anlamlı bir farklılık bulunmadı.

Sonuç: Değerlendirilen kompozit rezinlerin yüzey pürüzlülüğü, ağız ortamını taklit eden sıvılarda bekletilmelerinden farklı şekilde etkilendi.
