Özet
Amaç: Yüksek oranda doldurucu içeren üç farklı akışkan kompozit rezin yüzeyine uygulanan iki basitleştirilmiş çarklı cila sisteminin yüzey pürüzlülüğüne, parlaklığına ve renk stabilitesine etkilerini değerlendirmektedir. Gereç ve Yöntem: Çalışmamızda G-aenial Universal Injectable (GUI-GC, Japonya), Omnichroma Flow (OF-Tokuyama, Japonya), Clearfil Majesty Flow (CMF-Kuraray, Japonya) ve NeoSpectra ST HV (NS-Dentsply Sirona, Almanya) kompozit rezinlerinden 24 adet disk (8x2mm; n=96) hazırlandı. Örneklerin bir tarafı kontrol yüzeyi olarak bırakılırken diğer yüzeyleri 30'ar saniye süreyle Twist Dia (TWD-Noritake, Japonya) veya Nova Twist (NOV-President, Almanya) ile cilalandı. Bir profilometre cihazı (Mitutoyo Surftest/ SJ-301, Tokyo, Japonya) ile yüzey pürüzlülüğü ve Glossmetre cihazı (Glossmeter PCE-SGM60 Plus, ABD) ile parlaklık ölçümleri yapıldı. Bu ölçümlerden sonra örnekler 7 gün boyunca kahve çözeltisinde bekletildi. Renk ölçümleri (?E) CIEL*a*b* sistemine göre; başlangıçta, yedi gün sonra ve yeniden cilalamadan sonra bir spektrofotometre cihazı (Vita Easyshade, Vident, Brea, ABD) ile yapıldı. Her gruptan ikişer örnek kullanılarak tüm aşamalarda yüzeylerin taramalı elektron mikroskop (SEM) görüntüleri alındı. Yüzey pürüzlülük ve parlaklık değerleri tek yönlü ANOVA testi, post-hoc Tukey Testi ve Pearson Korelasyon testleri ile analiz edildi. Renk değişim değerleri Paired-T-test, Independent T-test, Multivariate ANOVA ve Dunnett-t post-hoc testleri ile değerlendirildi (p<0.05). Bulgular: TWD ve NOV ile cilalanmış olan gruplar yüzey pürüzlülüğü açısından karşılaştırıldığında, sadece NS grupları arasında fark olduğu saptandı (p<0.05). TWD ve NOV ile cilalanmış olan gruplar yüzey parlaklığı açısından karşılaştırıldığında, tüm gruplarda fark olduğu saptandı (p<0.05). Renklenme sonrasında, TWD gruplarından NS en çok renk değiştiren grup olurken (?E=4.90); CMF en az (?E=2.59) olandı (p=0.009). NOV gruplarında OF (?E=3.34) ve NS (?E=3.14) benzer şekilde en çok renk değiştiren gruplar olurken; GUF ve CMF daha az (sırasıyla 2.38 ve 2.82) renk değişimi gösterdi (p>0.05). Tekrar cilalama sonrasında TWD gruplarında tüm malzemelerin renkleri ?E<2 değerine döndü. NOV gruplarında sadece NS grubu ?E<2 düzeyine ulaşırken diğer gruplar bu sınırın üzerindeydi ve OF ile NS için fark anlamlıydı (p=0.011). SEM görüntülerine göre grupların yüzeyleri başlangıçta farklı olsa da; cilalama, renklendirme ve tekrar parlatma sonrasında çok az değişiklik gösterdi. Sonuç: Yüksek dolduruculu akışkan kompozit rezinlerde basitleştirilmiş çarklı sistemler ile cilalama pürüzsüz yüzeyler oluşturdu ancak parlaklık değerleri tüm gruplar için düşük bulundu. TWD ve NOV gruplarında NS en çok renk değişimi gösteren grup olurken; CMF daha az renklenendi. Tekrar cilalama sonrasında tüm TWD grupları ?E<2 değerine ulaşırken, NOV gruplarında sadece NS grubu bu değere ulaştı.
Aim To evaluate the effects of two simplified wheel polishing systems applied on three different highly filled flowable composite resin surfaces on surface roughness, gloss and color stability. Material and Methods Twenty-four-disc samples (8x2mm; n=96) were prepared with G-aenial Universal Injectable (GUI-GC, Japan), Omnichroma Flow (OF-Tokuyama, Japan), Clearfil Majesty Flow (CMF-Kuraray, Japan) and NeoSpectra ST HV (NS-Dentsply, Germany). One side of the samples was left as a control while the others were polished with Twist Dia (TWD-Noritake, Japan) or Nova Twist (NOV-President, Germany) for 30 sec. Surface roughness was measured with a profilometer (Mitutoyo Surftest/ SJ-301, Tokyo, Japan) and gloss measurements were performed with a Glossmeter (Glossmeter PCE-SGM60 Plus, USA). After these measurements specimens were immersed in coffee for 7 days. Color measurements (?E) according to CIEL*a*b* were performed with a spectrophotometer (Vita Easyshade, Vident, Brea, USA) at baseline, after 7 days of immersion and repolishing. Scanning electron microscope (SEM) images of the surfaces were taken at all stages using two samples from each group. Surface roughness and gloss values were analysed by one-way ANOVA test, post-hoc Tukey Test and Pearson Correlation tests. Color change values were evaluated with Paired-T-test, Independent T-test, Multivariate ANOVA and Dunnett-t post-hoc tests (p<0.05). Results The groups polished with TWD and NOV were similar on surface roughness values except for NS groups (p<0.05). They were significant differences in terms of gloss between all the groups polished with TWD and (p<0.05). In TWD groups, NS was the group that exhibiting the most color change (?E=4.90) while CMF was the least (?E=2.59) (p=0.009). In NOV groups, OF (?E=3.34) and NS (?E=3.14) were the groups having the most color change while GUF and CMF showed the less (2.38 and 2.82, respectively) (p>0.05). After re-polishing, the color of all materials in TWD groups changed to ?E<2. In NOV groups, only NS group reached ?E<2, while the other groups were above this limit, and the difference was significant for OF and NS (p=0.011). According to the SEM images, although the surfaces of the groups were different at the beginning; little change after polishing, coloration and re-polishing were observed. Conclusion Polishing with TWD and NOV in highly filled flowable composite resins produced smooth surfaces, but the gloss values were low for all groups. In TWD and NOV groups, NS was the group that showed the most color change and CMF was the least. After repolishing, all TWD groups reached ?E<2, while only the NS group reached this value in NOV groups. Keywords: Composite resin, highly filled flowable, surface roughness, color change, gloss
