Abstract

Objective: This study aimed to assess the effectiveness of shade selection and matching for esthetic region crown restorations using newly developed digital color selection techniques. Materials and Methods: Ten different crowns were fabricated with randomly selected colors and set as the target crowns. The test samples were randomly divided into four test groups: Group V, wherein the visual color selection was performed using the Vita 3D Master scala (control); Group OPT, wherein the color selection was performed by measuring the target tooth color using a novel clinical colorimeter device; Group SS, wherein the color selection was performed by measuring the target tooth color using a spectrophotometer; and Group IOS, wherein the color selection was performed by scanning the target crowns using intraoral scanning software. A total of 40 crowns were fabricated as test samples using the different shade selection techniques. The L, a*, and b* values of the samples and target crowns were measured using a spectrophotometer. The color difference(ΔE) values were calculated according to the CIEDE2000(2:1:1) formula. The collected data underwent appropriate statistical analysis (α=.05). Results: For Groups V, OPT, SS, and IOS, the average ΔE test values were 2.27, 1.11, 1.73, and 3.03, respectively. There was a statistically significant difference between these average ΔE values (P>.05).While there was no statistically significant difference between Groups S,V, and OPT there was a statistically significant difference between the three groups and Group IOS. Conclusion: Color selection techniques using visual methods, spectrophotometer, and Optishade were found to be more successful than color selections made with the intraoral scanner. Keywords: Colorimetry, Esthetics, Visual

Özet

Amaç: Çalışmanın amacı, yeni geliştirilen dijital renk seçim teknikleri kullanılarak üretilen estetik bölge kron restorasyonlarının renk seçimi başarısını değerlendirmektir. Gereç ve Yöntemler: Rastgele boyama yapılarak on farklı renkte kron üretildi ve hedef kron olarak belirlendi. Dört test grubu oluşturuldu: Grup V, görsel renk seçimi Vita 3D Master renk sistemi kullanılarak yapıldı (kontrol grubu); Grup OPT, yeni bir klinik kolorimetre cihazı kullanılarak hedef diş renginin ölçülmesiyle gerçekleştirildi; Grup SS, bir spektrofotometre kullanılarak hedef diş renginin ölçülmesiyle gerçekleştirildi; ve Grup IOS, renk seçimi intraoral tarama cihazı kullanılarak hedef kuronların taranmasıyla gerçekleştirildi. Farklı renk seçim teknikleri kullanılarak toplam 40 adet kron üretildi. Test örnekleri ve hedef kronların L, a* ve b* değerleri bir spektrofotometre kullanılarak ölçüldü. Renk farkı (ΔE) değerleri CIEDE2000 (2:1:1) formülüne göre hesaplandı. Toplanan veriler için uygun istatistiksel analiz yapıldı (α=0,05). Bulgular: Grup V, OPT, SS ve IOS için ortalama ΔE testi değerleri sırasıyla 2,27, 1,11, 1,73 ve 3,03. Ortalama ΔE değerleri arasında anlamlı fark vardı (P>.05). Grup SS, V ve OPT arasında istatistiksel olarak anlamlı fark bulunmazken, üç grup ile Grup IOS arasında istatistiksel olarak anlamlı fark vardı. Sonuç: Görsel,spektrofotometre ve Optishade ile yapılan renk seçimleri ağız içi tarayıcı ile yapılan renk seçiminden daha başarılı bulunmuştur. Anahtar Kelimeler: Estetik, Görsel, Kolorimetre
