Abstract
Objectives: The aim of this in vitro study wasto evaluate the affect of pre-heating on colorstability of a microhybrid composite resinMaterials and Methods: In this study an A1shade microhybrid resin composite (Filtek Z250,3M ESPE) was used after storage in 4 differenttemperatures (4ºC, 23 ºC, 37 ºC, 55 ºC). Forty discshaped specimens were prepared in a teflon moldwith a diameter of 10 mm and a depth of 2 mm(n=10). In the first group the specimens were storedin refrigerator at 4 ºC and the 2nd group were keptin room temprature at 23 ºC. In the 3rd and 4thgroups a composite warmer (Micerium, S.p.a.,Avegno GE, Italy) were used for heating the tubesup to 37 ºC and 55 ºC, respectively. The specimenswere light cured for 40 s with a quarts tungstenhalogen curing unit (Smart-Lite, Benlioğlu Dental,Ankara, Turkey). The baseline and after 48 hoursstorage in the coffee solution (Nescafe Classic) thecolor measurements of the specimens were detectedwith Vita Easy-Shade digital colorimeter deviceand ∆E were calculated. The data were analysedwith parametric one-way ANOVA and Tukey HSDtests.Results: The composite group pre-heated to 37ºC and 55 ºC showed significantly lower ∆E valuesthan the groups at 4 ºC ve 23 ºC (p<0.01).Conclusion: Pre-heating of the microhibritcomposite caused lower discoloration.

ÖZET
Amaç: Bu çalışmanın amacı farklı ön-ısıtma işlemlerinin mikrohibrit bir kompozit rezinin renk değişimine etkisini in vitro incelemektir.
Gereç ve Yöntem: Bu çalışmada 4 farklı ısıda bekletilen (4ºC, 23 ºC, 37 ºC, 55 ºC) A1 rengindeki mikrohibrit yapıda bir kompozit rezinden (Filtek Z250,3M ESPE) 10 mm çapında ve 2 mm derinliğinde 40 adet disk şeklinde örnek hazırlanmıştır (n=10). Bu amaçla örnekler; 1. grupta 4 ºC’de buzdolabında, 2. grupta 23 ºC’de oda sıcaklığında bekletildi. Diğer kompozit tüplerini 37 ºC (3. Grup) ve 55 ºC’ ye (4.Grup) getirmek amacıyla kompozit ısıtma cihazı (Micerium, S.p.a., Avegno GE, Italy) kullanıldı. Hazırlanan örnekler halojen ışık cihazı (Smart-Lite, Benlioğlu Dental, Ankara, Türkiye) ile 40 saniye polimerize edildi. Örneklerin başlangıç renk değerleri Vita Easy-Shade dijital kolorimetre cihazı ile tespit edilip kaydedildi. Daha sonra örnekler hazırlanan kahve solüsyonunda (Nescafe Classic) 48 saat bekletildi. Çıkarılan örnekler yıkanıp kurulandıktan sonra tekrar dijital kolorimetre cihazı ile renk değerleri tespit edilerek renk farklılıkları (∆E) hesaplandı. Renk farklılıkları verileri tek yönlü ANOVA ve Tukey testi kullanılarak değerlendirildi.
Bulgular: Polimerizasyon öncesinde 37 ºC ve 55 ºC’ye ısıtılan gruplar arasında anlamlı fark bulunmazken bu gruplarda 4ºC ve 23 ºC’deki gruplardan anlamlı bir şekilde daha düşük ∆E değerleri tespit edilmiştir (p<0.01).
Sonuç: Mikrohibrit yapıdaki bir kompozitte polimerizasyon öncesi ısıtma işlemi daha az renk değişimine neden olmuştur.
