Effect of Application Phase of Different Adhesive Systems on Coronal Discoloration Caused by Endoseal MTA: An In-vitro Study

Abstract

Objectives: This in-vitro study evaluated the effect of different application phases of dentin bonding agents (DBA) on preventing crown discoloration caused by a calcium silicate-based root canal sealer. Materials and Methods: Samples were divided into three main groups: Pre-preparation, Pre-obturation, and Pre-preparation/Pre-obturation, with each group further divided based on adhesive systems. DBA was applied before irrigation in the Pre-preparation, after irrigation in the Pre-obturation, and both before and after irrigation in the Pre-preparation/Pre-obturation groups. After applying the sealer, color measurements were recorded at baseline (T0), 1 month (T1), and 6 months (T2). Results: Findings showed that application phase, evaluation period and the interaction between these factors significantly affected discoloration. The lowest color change was observed between T1-T0, with significant differences between evaluation periods. The highest color change occurred in the Pre-preparation and control groups at T2-T0 compared to other groups. However, all groups showed color changes above the clinical acceptability (>1.8) and perceptibility thresholds (>0.8). Conclusion: The application phase of DBA and evaluation period significantly influenced crown discoloration, with the greatest changes observed during the pre-preparation phase, emphasizing the critical role of procedural timing in minimizing aesthetic impacts.

Farklı Adeziv Sistemlerin Uygulanma Aşamasının Endoseal MTA'nın Neden Olduğu Koronal Renk Değişikliğine Etkisi: Bir İn-vitro Çalışma

Öz

Amaç: Bu in vitro çalışmada, kalsiyum silikat esaslı kök kanal patının neden olduğu koronal renk değişikliğini önlemede dentin bonding ajanlarının (DBA) farklı uygulanma aşamalarının etkisi değerlendirilmiştir. Gereçler ve Yöntemler: Örnekler üç ana gruba ayrıldı: Preparasyon öncesi, Obturasyon öncesi ve Preparasyon öncesi /Obturasyon öncesi. Her grup daha sonra adeziv sistemlere göre subgruplara ayrıldı. DBA, Preparasyon öncesi grubunda irrigasyondan önce; Obturasyon öncesi grubunda irrigasyondan sonra ve Preparasyon öncesi /Obturasyon öncesi gruplarında irrigasyondan önce ve sonra uygulandı. Kanal patı uygulandıktan sonra, renk ölçümleri başlangıçta (T0), 1 ayda (T1) ve 6 ayda (T2) kaydedildi. Bulgular: Analiz sonuçları, uygulama aşamasının, değerlendirme zamanının ve bu faktörler arasındaki etkileşimin renk değişikliğini önemli ölçüde etkilediğini gösterdi. En düşük renk değişimi T1-T0 arasında gözlendi ve değerlendirme periyodları arasında önemli farklılıklar vardı. T2-T0 değerlendirme periyodunda, en fazla renk değişimi diğer gruplara kıyasla Preparasyon öncesi ve kontrol gruplarında meydana geldi. Ancak tüm gruplar klinik kabul edilebilirlik (>1.8) ve algılanabilirlik eşiklerinin (>0.8) üzerinde renk değişimleri gösterdi. Sonuçlar: DBA uygulanma aşaması ve değerlendirme zamanı krondaki renklenmeyi önemli ölçüde etkiledi, en fazla renk değişimi Preparasyon öncesi grubunda gözlendi ve bu da estetik etkileri en aza indirmede prosedür zamanlamasının kritik rolünü vurguladı.
