Abstract

Amaç: Bu çalışmanın amacı, polimerizasyon öncesi ön ısıtmanın kompozit rezinlerin renk stabilitesi ve yüzey parlaklığı üzerindeki etkilerini araştırmaktır.
Yöntemler : Farklı partikül boyutlarına sahip 3 farklı kompozit rezinden toplam 90 örnek (8mmx 2 mm) hazırlandı. Örneklerin yarısı oda sıcaklığındaki kompozit tüplerden, diğer yarısı ise Ease-ItTM ısıtma cihazı ile 60°C'ye ısıtılmış kompozit tüplerden hazırlandı (n:15). Polimerizasyon ve parlatma işlemlerinden sonra spektrofotometre ile renk ölçümleri ve Glossmetre ile yüzey parlaklığı ölçümleri yapılmıştır. Tüm numuneler 10.000 döngülük bir termal döngüye tabi tutulmuş ve ölçümler tekrarlanmıştır. Sayısal verilerin gruplar arasındaki normal dağılımını değerlendirmek için Kolmogorov-Smirnov testi kullanılırken, varyansın homojenliğini değerlendirmek için Levene testi kullanılmıştır (P<,05).
Bulgular : Önceden ısıtılmış ve ısıtılmamış kompozit rezinlerin parlaklık değerlerinde istatistiksel olarak anlamlı bir fark yoktu (P>,05). Isıl işlem kompozit tipleri arasında istatistiksel olarak anlamlı bir farka neden olmazken (P>,05), ortalama renk değişim değerlerinde istatistiksel olarak anlamlı bir farka neden olmuştur (P<,001). Isıtılan grupların ortalama renk değişim değerleri ısıtılmayan gruplardan anlamlı derecede düşüktü (P<,05).
Sonuç : Ön ısıtma işlemi kompozit rezinlerin parlaklık değerleri üzerinde anlamlı bir fark yaratmamıştır; ancak renk değişimini önemli ölçüde azaltmıştır.
Anahtar Kelimeler: Kompozit rezin, Isıtma, Polimerizasyon, Boyanma, Yüzey parlaklığı.

Investigation of the Effect of Preheating Before Polymerization on the Color and Gloss of Composites

Abstract

Objective: The aim of this study was to investigate the effects of preheating on the color stability and surface gloss of composite resins before polymerization.
Methods: A total of 90 samples (8 mmx 2 mm) of three composite resins with different particle sizes were prepared. Half of the samples were prepared from composite tubes at room temperature and the other half were prepared from composite tubes preheated to 60°C with the Ease-ItTM heating device (n=15). After polymerization and polishing, color measurements were performed using a spectrophotometer and surface gloss was measured with a glossmeter. All samples underwent 10,000 thermal cycles, after which measurements were repeated. The Kolmogorov-Smirnov test was used to assess the normality of data distribution, and Levene's test was applied to evaulate homogeneity of variance (P<.05).
Results: There was no statistically significant difference in the gloss values of preheated and unheated composite resins (P>.05). Heat treatment did not cause a statistically significant difference between the composite types (P>.05), but it caused a statistically significant difference in the mean color change values (P<.001). The average color change values of the preheated groups were significantly lower than the unheated groups (P<.05).
Conclusion: Preheating composite resins prior to polymerization did not significantly affect surface gloss but significantly reduced discoloration.
