EVALUATION OF COLOR STABILITY AND COLOR ADAPTATION ABILITY OF A SINGLE SHADE UNIVERSAL RESIN COMPOSITE TO NATURAL TOOTH TISSUE

Abstract

with a singleshade universal composite resin, and the color change resulting from aging of the enamel and restoration in different beverages, and the correlation between them. Class V cavities were drilled into the labial surfaces of 50 maxillary anterior permanent human teeth and restored with Omnichroma (Tokuyama, Tokyo, Japan). The color of the restoration and enamel was measured with a spectrophotometer. To measure the color stability, teeth divided into 5 groups as red wine, cola, turnip, coffee, and distilled water (n=10). The color measurements were repeated at 1, 3, 7, and 14 days. The color change was calculated using CIEDE2000 formula. The blending effect of the restoration and surrounding enamel was above the aceptable thre shold regarding hue and chroma. Turnip caused the mostcolor change of the restoration for all measurement times (p<0.05). No correlation was found between the colorchange of the tooth and restoration at days 7 and 14 for all beverages. Universal composite resin showed an acceptable match with the color of the enamel. However, the color difference increases with the aging in different liquids.

TEK RENK UNIVERSAL BİR REZİN KOMPOZİTİN RENK KARARLILIĞININ VE DOĞAL DİŞ DOKUSUNA RENK UYUM YETENEĞİNİN DEĞERLENDİRİLMESİ

Abstract

başlangıç uyumunun ve mine ve restorasyonun farklı içeceklerde yaşlandırılması sonucunda oluşan renk değişiminin ve aralarındaki korelasyonun değerlendirilmesidir. 50 adet maksiler anterior daimi insan dişinin labial yüzeylerine Sınıf V kaviteler açıldı ve Omnichroma (Tokuyama, Tokyo, Japonya) ile restore edildi. Restorasyonun ve minenin rengi bir spektrofotometre ile ölçüldü. Renk stabilitesini ölçmek için dişler kırmızı şarap, kola, şalgam, kahve ve distile su olmak üzere 5 gruba ayrılmıştır (n=10). 1, 3, 7 ve 14 gün sonrasında renk ölçümleri tekrarlanmıştır. Renk değişimi CIEDE2000 formülü kullanılarak hesaplanmıştır. Restorasyonun ve çevresindeki minenin harmanlama etkisi renk tonu ve renk doygunluğu parametreleri açısından kabul edilebilirlik eşiğinin üzerindedir. Tüm ölçüm zamanları için restorasyonun en fazla renk değişimine şalgam sebep olmuştur (p<0.05). Diş ve kompozit restorasyonun tüm içecekler için 7 ve 14. günlerde renk değişim açısından korelasyon elde edilmemiştir. Tek renk universal rezin kompozit, minenin rengiyle kabul edilebilir bir uyum göstermekte, ancak farklı sıvılarda yaşlanmanın etkisi ile renk farkı artmaktadır.
