Farklı Beyazlatıcı Ağız Gargaralarına Maruz Bırakılan Bir Nano-Hibrit Kompozitin Renk Değişikliğinin İncelenmesi

Bu çalışmanın amacı farklı beyazlatıcı ağız gargaralarının bir nano-hibrid kompozitin renk parametreleri üzerine olan etkilerinideğerlendirmektir. Bir nano- hybrid kompozitten 3M ESPE Z550 yetmiş adet kompozit rezin disk 8 mm x 1 mm hazırlandı.Başlangıçta, örnekler 37 ºC deki distile suda 24 saat süresince bekletildi. Kompozit örneklerin ilk renk parametreleri klinik tipi birspektrofotometre ile, CIE L*a*b*renk skalası esas alınarak ölçüldü ve kompozit örnekler rastgele yedi gruba ayrıldı n=10 . Üç hidrojenperoksit içeren Listerine Whitening Vibrant, Scope White, Crest 3D White ve üç hidrojen peroksit içermeyen olmak üzere toplam altıbeyazlatıcı gargara test edildi. Distile su ise kontrol olarak kullanıldı. 1 saat ve 24 saat sonunda renk ölçümleri tekrarlandı renk değişimlerianaliz edildi. İstatistiksel analizler ANOVA ve Tukey's çoklu karşılaştırma testi kullanılarak yapıldı. Grupların hiçbirinde kabul edilemezbir renk değişimi oluşmadı. Solüsyonda bir saat bekletilen örneklerde 0.97 Listerine Whitening Vibrant ile 2.32 Oral-B 3D White arasında renk değişimi oluştu ki kontrol grubu için ΔE* değeri 0.67 idi. 24 saat sonra ise ΔE*değerleri 0.65 Listerine Whitening Vibrant ile 2.73 Oral-B 3D White arasında değişti. Bu çalışmanın sınırları dahilinde test edilen beyazlatıcı ağız gargaralarının, seçilen güncel birkompozit rezinde, belirgin renk değişimine sebep olacak seviyede renk değişimine neden olmadığını belirtebiliriz

Color Change of a Nano-hybrid Composite Exposed to Different Whitening Mouth Rinses

The aim of this study was to evaluate the effect of whitening mouth rinses on the color parameters of a nano-hybrid composite. Seventycomposite resin disks 8 mm x 1 mm were fabricated from a nano-hybrid composite resin. 3M ESPE Z550 At the beginning, sampleswere stored in distilled water at 37ºC for 24 hours. The initial color parameters of composite samples were measured with a clinicalspectrophotometer according to the CIE L*a*b*color scale and then composite samples were randomly divided into seven groups n=10 . Atotal of six whitening mouth rinses; three hydrogen peroxide including Listerine Whitening Vibrant, Scope White, Crest 3D White andthree non hydrogen peroxide including Oral-B 3D White, Signal White Now, Colgate Optic white were tested. Distilled water was usedas a control. After 1 hour and 24 hours exposure periods color measurements were repeated and color changes were analyzed. Statisticaldifferences were analyzed using ANOVA and Tukey ’s HSD post hoc tests. None of the groups had an unacceptable color change. Onehour exposure to solutions caused color changes between 0.97 Listerine Whitening Vibrant , and 2.32 Oral-B 3D White where ΔE*forcontrol group was 0.67. Also after 24 hours, ΔE*values were in range of 0.65 Listerine Whitening Vibrant and 2.73 Oral-B 3D White .Within the limitations of this study, we can conclude that tested whitening mouth rinses are not capable to cause perceptible color changeson selected novel composite resin
