Özet:

 Background: The aim of this study was to compare the color stability of two different universal shade composite resins after coffee staining and bleaching with 40  H₂O₂. Methods: Restorations Depth: 2 mm and Diameter: 8 mm were performed using Omnichroma BO and Essentia Universal LE composite resins on the buccal and lingual surfaces of 10 removed caries-free molars, using selective etching and a universal adhesive. CIE L, a, b values were performed on the initial, 1st, 6th, and 12th days of immersion in coffee and after 40 H₂O₂ bleaching agent using a spectrophotometer. Values of ΔE00, ΔL, ΔC, and ΔH were calculated using the CIEDE2000 formula. Mann-Whitney U test was used to compare ΔE00, ΔL, ΔC and ΔH values according to the materials. General Linear Model Variance Components test was used to determine the effect of ΔL, ΔC and ΔH values on ΔE00 values p0.05. Results: The ΔE00 and ΔL values for BO and LE materials were not statistically significant p0.05. After bleaching, ΔL and ΔC were shown to be effective for both BO and LE in Ta measurements, whereas ΔH was ineffective. Conclusion: Within the limitations of this study, it was found that BO and LE materials stained to clinically unacceptable levels, while bleaching procedures showed good effectiveness results on both materials.

 Amaç: Bu çalışmanın amacı iki farklı universal renkli kompozit rezinin kahve solüsyonu ile renklenme miktarının belirlenmesi ve renklenmiş restorasyonlar üzerine  40lık H₂O₂ ağartma ajanı uygulanması sonrasındaki renk stabilitesinin belirlenerek bunların kompozit türlerine göre karşılaştırılmasıdır. Gereç ve Yöntemler: Çekilmiş 10 adet çürüksüz büyük azı dişlerinin bukkal ve lingual yüzeylerine 8 mm çapında 2 mm derinliğinde açılan kavitelere selektif asitleme ve universal adeziv kullanılarak Omnichroma BO ve Essentia Universal LE kompozit rezin materyalleriyle restorasyonları yapılmıştır. Başlangıç, kahve solüsyonunda 1., 6. ve 12. gün renk ölçümleri ve  40 H₂O₂ ağartma sonrasında CIE L, a, b değerleri spektrofotometre ile ölçülmüştür. CIEDE2000 formüllü kullanılarak ΔE00, ΔL, ΔC ve ΔH değerleri hesaplanmıştır. Materyallere göre ΔE00, ΔL, ΔC ve ΔH değerlerinin karşılaştırılmasında Mann-Whitney U testi, ΔE00 değerleri üzerinde ΔL, ΔC ve ΔH değerlerinin etkisinin belirlenmesinde General Linear Model Variance Components testi kullanılmıştır p0.05. Bulgular: BO ve LE materyalleri üzerinde ölçüm yapılan zaman dilimlerinin her birinden elde edilen ΔE00 ve ΔL değerleri istatistiksel olarak anlamlı değildir p0.05. Ağartma sonrası alınan Ta ölçümlerinde hem BO için hem de LE için ΔH etkisiz, ΔL ve ΔC etkili olmuştur. Sonuçlar: Bu çalışmanın limitasyonları dahilinde, BO ve LE materyallerinin klinik olarak kabul edilemez seviyelerde renklendiği ve ağartma prosedürlerinin her iki materyal üzerinde iyi etkinlik gösterdiği bulunmuştur. Anahtar Kelimeler: Ağartma ajanı, kompozit dental rezin, renk.
