OBJECTIVE: The aim of this study was to evaluate the effect of thermocycling on the color stability of three indirect composite resins.

MATERIALS AND METHOD: In this study, three indirect composite resins: Artglass, Solidex and Signum were tested. Ten specimens (10 mm diameter and 2 mm depth) were prepared from each composite material and were polymerized at both sides for 180 s at 320-500 nm using a xenon stroboscopic light curing unit. The specimens were then subjected to polishing procedures using medium, fine and super fine grit aluminum oxide discs. After initial measurements were made with a colorimeter according to CIELAB system, specimens were subjected to 5000 thermocycles between 5 oC and 55 oC with a dwell time of 25 s in each bath and with a transfer time of 10 s between baths. After the thermocycling procedure, colors of the specimens were re-measured and color changes (∆E) were determined.

RESULTS: The color change for all composite resin materials were above the clinically acceptable limit (∆E>3.3). The greatest color change was found for Solidex composite resin samples (∆E=6.87); this value was significantly different from those for Artglass (∆E=4.87) and Signum (∆E=5.27) samples (p<0.05). Color change values for the Artglass and Signum samples were not statistically different from each other (p>0.05).

CONCLUSION: After thermocycling, the color changes of all the tested indirect composites were above the clinically accepted values. In clinical application, these results should be considered during composite resin selection, and teeth restored with indirect resin should be controlled more frequently.

Termal siklusun indirekt kompozit rezin materyallerinin renk stabilitesi üzerine etkisi

Öz

AMAÇ: Termal siklus uygulamasının üç indirekt kompozit
rezin materyalinin renk stabilitesi üzerine etkisinin in vitro
olarak değerlendirilmesidir.
GEREÇ VE YÖNTEM: Çalışmada Artglass, Solidex ve Signum
olmak üzere üç farklı indirekt kompozit rezin materyali kullanıldı.
Her bir indirekt kompozit rezin materyalinden, 10
adet olmak üzere test örnekleri (10 mm çapında, 2 mm kalınlığında)
hazırlandı ve 320-500 nm dalga boyu xenon stroboskopik
ışık cihazıyla her iki yüzden 180 sn süreyle
polimerize edildi. Polimerizasyon sonrası örnekler, orta,
ince ve çok ince grit alüminyum oksit diskler ile cilalandı.
Daha sonra, kompozit rezin örneklerin kolorimetre cihazı
ile ilk renk ölçümleri CIELAB renk sistemine göre yapıldı.
Ardından örnekler sırası ile 5 °C ve 55 °C (±2 °C) su banyolarında
25’er sn bekleyecek ve banyolar arası geçiş 10 sn
olacak şekilde 5000 termal siklusa maruz bırakıldı. Termal
siklus sonrası, örneklerin renk ölçümleri tekrar yapıldı ve
renk değişim değerleri (∆E) tespit edildi.
BULGULAR: Elde edilen renk değişim değerleri tüm kompozit
rezinlerde klinik olarak kabul edilebilir değerlerin üzerinde
bulundu (∆E > 3.3). En fazla renk değişimi Solidex
kompozit rezin için görülürken (∆E=6,87), bu değer Artglass
(∆E=4,87) ve Signum (∆E=5,27) örneklerinden istatistiksel
olarak farklı bulundu (p < 0.05). Artglass ve Signum’da
renk değişim değerleri istatistiksel olarak birbirinden farklılık
göstermedi (p > 0.05).
SONUÇ: Termal siklus uygulamasından sonra, çalışmada
kullanılan bütün indirekt kompozit rezinler klinik olarak
kabul edilebilir değerlerin üzerinde renk değişimi göstermekle
birlikte, en yüksek renk değişim değerini Solidex
kompozit göstermiştir. Klinik uygulamalarda bu sonuçlar
göz önüne alınarak uygun kompozit seçimi yapılmalı ve indirekt
kompozit uygulanan dişlerin klinik kontrolleri daha
sık aralıklarla yapılmalıdır.
