Dört Farklı Monokromatik Üniversal Rezin Kompozitin Renk Eşleşme Yeteneğinin Spektrofotometrik Analizi

Öz

Giriş Bu çalışmanın amacı, dört farklı monokromatik üniversal rezin kompozitin renk uyum yeteneğini değerlendirmektir. Gereç ve Yöntem Çalışmada değerlendirilen kompozit rezinler şunlardır: G1: Omnichroma (Tokuyama Dental), G2: Vittra Unique (FGM), G3: Zenchroma (President Dental) ve G4: Essentia Universal (GC). Her bir kompozitin renk uyumunu değerlendirmek amacıyla beş farklı akrilik santral kesici diş rengi (B1, A2, C2, A3.5, D3) Vita Classical Renk Skalası’na göre seçilmiş ve doğrulanmıştır. Her grup, 25 örnekten oluşmuş (N=100) ve akrilik dişlerin orta bukkal yüzeylerine 1.5×1.5 mm boyutlarında yuvarlak kaviteler hazırlanmıştır. Kompozit rezinler kaviteler içine yerleştirilmiş ve LED ışık kaynağı ile 20 saniye polimerize edilmiştir. Renk ölçümleri, gri bir arka plan önünde gün ışığında spektrofotometre ile yapılmış; ortalama Lab* farkları ΔE değeri olarak ifade edilmiştir (eşik değer=3.3). Veriler ANOVA ve Tukey post-hoc testi ile analiz edilmiştir (p<0.05). Bulgular B1 renginde Omnichroma, Zenchroma ve Essentia Universal arasında anlamlı farklar saptanmıştır (p<0.05). A2 renginde en iyi uyum Omnichroma’da gözlenirken, C2’de Zenchroma üstün performans göstermiştir (ΔE=1.33, p<0.05). A3.5 renginde tüm materyallerde fark algılanabilir düzeyde olup en iyi sonuç Essentia Universal’de elde edilmiştir (ΔE=4.05). D3 renginde ise Zenchroma ve Essentia Universal istatistiksel olarak daha iyi renk uyumu sergilemiştir (p<0.05). Sonuç Tüm Vita renk skalasıyla uyum gösterecek şekilde üretilmiş olsalar da, monokromatik üniversal rezin kompozitlerin renk uyum yeteneği marka ve diş rengine göre farklılık göstermektedir.

Color Matching Ability of Four Different Monochromatic Universal Resin Composites: A Spectrophotometric Analysis

Öz

Introduction This study aimed to assess the color-matching ability of four different monochromatic universal resin composites. Materials and Methods The composite resins evaluated in the study were: G1: Omnichroma (Tokuyama Dental); G2: Vittra Unique (FGM); G3: Zenchroma (President Dental); and G4: Essentia Universal (GC). To assess the color-matching ability of each composite resin, five different shades of acrylic central incisor teeth (B1, A2, C2, A3.5, D3) were selected and verified according to the Vita Classical Shade Guide to ensure the accuracy of the acrylic tooth color. Each group consisted of twenty-five samples (N=100) prepared accordingly. Round cavities (1.5 mm × 1.5 mm) were prepared on the mid-buccal surfaces of the acrylic incisors. Composite resins were placed in the prepared cavities and polymerized with a LED light for 20 seconds. Color measurements were taken in daylight against a gray background using a spectrophotometer, and mean L*a*b* differences were expressed as ΔE values (threshold value=3.3). Data were analyzed with ANOVA and Tukey’s post-hoc test (p<0.05). Results In the B1 tooth shade, Omnichroma, Zenchroma, and Essentia Universal showed significant color differences (p<0.05). Omnichroma achieved the best match for A2, while Zenchroma showed superior performance for C2 (ΔE = 1.33, p<0.05). In A3.5, all materials displayed perceptible differences, with Essentia Universal performing best (ΔE=4.05). For D3, both Zenchroma and Essentia Universal exhibited superior color-matching abilities (p<0.05). Conclusion Although designed to match all Vita shades, the color compatibility of monochromatic universal composites varied by brand and tooth shade.
