AB  - Aims: This study aimed to compare the long-term color stability of two different 3D-printed resins, one CAD/CAM resin nanoceramic block, and one nanohybrid composite resin after immersion in a coffee solution.Methods: Specimens were prepared from four resin-based materials produced via different manufacturing techniques: subtractive manufacturing (Cerasmart-group CS), additive manufacturing (VarseoSmile Crown Plus-group VS, Crowntec-group CT), and conventional methods (Clearfil Majesty Esthetic-group CME). The samples were immersed in coffee for 45 minutes daily over 30 days and stored in distilled water for the rest of the day. Color measurements were taken using a spectrophotometer on days 1, 7, 14, and 30. Color changes (ΔE) were calculated using the CIEDE2000 formula. Data were analyzed using one-way ANOVA, and post hoc comparisons were performed using the Tukey test. A p-value 1.8). Further studies are needed to evaluate the color stability of 3D printing resins and additive manufacturing techniques.

N2  - Amaç:Bu çalışmanın amacı, kahve solüsyonuna daldırma sonrası iki farklı 3D baskı reçinesi, bir CAD/CAM reçine nano-seramik blok ve bir nanohibrit kompozit reçinenin uzun dönem renk stabilitelerini karşılaştırmaktı.Gereç ve Yöntem:Farklı üretim teknikleriyle üretilmiş dört farklı reçine esaslı materyalden örnekler hazırlandı: Eksiltmeli üretim (Cerasmart – Grup CS), Eklemeli üretim (VarseoSmile Crown Plus – Grup VS, Crowntec – Grup CT) ve geleneksel direkt kompozit yöntem (Clearfil Majesty Esthetic – Grup CME). Örnekler, 30 gün boyunca her gün 45 dakika kahve solüsyonuna daldırıldı ve günün kalan süresinde distile suda saklandı. Renk ölçümleri 1., 7., 14. ve 30. günlerde spektrofotometre ile yapıldı. Renk değişimleri (ΔE), CIEDE2000 formülü kullanılarak hesaplandı. Veriler tek yönlü ANOVA testi ile analiz edildi, anlamlı farklılıklar Tukey testi ile değerlendirildi. p 1.8) üzerinde renk değişimi gösterdi. 3D baskı reçineleri ve eklemeli üretim tekniklerinin renk stabilitesini değerlendirmek için daha fazla çalışmaya ihtiyaç vardır.
