Amaç: Bu çalışmada, farklı kalınlıklarda hazırlanan kompozit rezinlerin ön ısıtma sonrası renk stabilitesi ve polimerizasyon derinliğinin karşılaştırılması amaçlandı. Gereç ve Yöntemler: İkisi anterior (Clearfil Majesty Anterior, Geanial Anterior) ikisi posterior (Clearfil Majesty Posterior, Gaenial Posterior) dişlerde kullanılmak üzere üretilmiş toplam 4 kompozitin her birinden oda sıcaklığında (25°C) ve ön ısıtma işlemine tabi tutularak (60°C), 2 mm ve 3 mm olacak şekilde iki farklı kalınlıkta toplam 32 örnek (n=8) hazırlandı. 24 saat distile suda bekletilen örnekler başlangıç sertlik ve renk ölçümlerinin ardından kahve solüsyonu ile renklendirme prosedürüne maruz bırakıldı. Renklendirme prosedürü sonrası renk ölçümleri tekrarlandı. Elde edilen verilerin analizi Bağımsız örneklerde t-testi, üç yönlü varyans analizi ve Tukey ''post hoc'' testleri kullanılarak yapıldı. İstatistiksel anlamlılık düzeyi p<0,05 olarak alındı. Bulgular: Polimerizasyon derinliği bulguları incelendiğinde, en yüksek değer 2 mm kalınlıkta hazırlanan Clearfil Majesty Posterior grubunda (0,92±0,35) elde edilirken, kalınlık artışı tüm gruplarda polimerizasyon derinliğinde azalmaya sebep olmuştur (p<0,05). Oda sıcaklığında hazırlanan G-aenial Posterior ve her iki sıcaklıkta hazırlanan Clearfil Majesty Esthetic gruplarında bu azalma istatistiksel olarak anlamlı bulunmuştur. Ön ısıtma işlemi Gaenial Posterior ve Clearfil Majesty Esthetic kompozitlerle hazırlanan 3 mm'lik örneklerin polimerizasyon derinliğini istatistiksel olarak anlamlı derecede artırmıştır (p<0,05). Renklenme bulgularına bakıldığında ise ön ısıtma işleminin G-aenial Anterior 2 mm-3 mm kompozit grupları ve Clearfil Majesty Esthetic 2 mm grubu haricî diğer gruplarda ΔE00 değerlerinde azalma sağlamadığı görülmüştür. Sonuç: Bu çalışmanın sınırları içerisinde ön ısıtma işleminin kullanılan anterior ve posterior kompozitlerde çoğunlukla polimerizasyon derinliğini artırdığı ancak örneklerin ΔE00 değerlerinde çoğunlukla anlamlı bir farklılığa sebep olmadığı gözlemlenmiştir.

Objective: In this study, it was aimed to compare the color stability and polymerization depth of composite resins prepared in different thicknesses after preheating. Material and Methods: In this study, a total of four composites were used, two designed for anterior teeth (Clearfill Majesty Anterior, Gaenial Anterior) and two for posterior teeth (Clearfill Majesty Posterior, Gaenial Posterior). From each composite, 32 samples were prepared in two different thicknesses (2 mm and 3 mm), under two conditions: at room temperature (25°C) and after preheating (60°C). After being stored in distilled water for 24 hours, the samples underwent initial hardness and color measurements, followed by a staining procedure with coffee solution. After the staining procedure, color measurements were repeated. The data were analyzed using independent samples t-test, three-way ANOVA, and Tukey post-hoc tests. The level of statistical significance was set at p<0.05. Results: When the polymerization depth findings were examined, the highest value was obtained in the Clearfil Majesty Posterior group (0.92±0.35), which was prepared with a thickness of 2 mm, and the increase in thickness caused a decrease in the polymerization depth in all groups (p<0.05). This decrease was statistically significant in the G-aenial Posterior group prepared at room temperature and the Clearfil Majesty Esthetic group prepared at both temperatures. The preheating process statistically significantly increased the polymerization depth of 3 mm samples prepared with G-aenial Posterior and Clearfil Majesty Esthetic composites (p<0.05). Considering the coloration findings, it was seen that the preheating process did not reduce the ΔE00 values in the groups except the G-aenial Anterior 2 mm-3 mm composite groups and the Clearfil Majesty Esthetic 2 mm group. Conclusion: Within the limits of this study, it was observed that the preheating process increased the polymerization depth in the anterior and posterior composites used but did not cause a significant difference in the ΔE00 values of the specimens.
