Ağartılmış Diş Dokularına Rezin Bağlanma Dayanımında Yeşil Çay, Biberiye ve Bunların Kombinasyonunun Antioksidan Etkileri

Amaç: Bu çalışmanın amacı, ağartılmış mine ve dentine kompozit rezin bağlanma dayanımında dört farklı antioksidan tedavi protokolünün etkisini değerlendirmektir. Gereç ve Yöntemler: Çalışmada 280 adet çekilmiş sığır keser dişinden 140’ar adet mine ve dentin örneği elde edildi. Mine ve dentin örnekleri kendi aralarında yedişer gruba ayrıldı (n=20): ENC/DNC= negatif kontrol, EPC/DPC= pozitif kontrol, EDR/DDR= ertelenmiş restorasyon, ESA/DSA= sodyum askorbat, EGT/DGT= yeşil çay, ER/DR= biberiye, EGTR/DGTR= yeşil çay ve biberiye kombinasyonu. Sodyum askorbat, yeşil çay ekstraktı, biberiye ekstraktı ve yeşil çay ve biberiye ekstrakt kombinasyonundan %10 konsantrasyonda hazırlanan deneysel antioksidan solüsyonları ESA/DSA, EGT/DGT, ER/DR ve EGTR/DGTR gruplarında yer alan örneklerin ağartılmış mine/dentin yüzeylerine uygulandı. Makaslama bağlanma dayanımı (MBD) analizi, kafa hızı 0,5 mm/dakika olarak ayarlanan test cihazında gerçekleştirildi. Kırılma tipleri, stereomikroskop altında x40 büyütme ile değerlendirildi. Verilerin istatistiksel analizinde Welch ANOVA ve post-hoc Tamhane testleri kullanıldı. Bulgular: En düşük ve en yüksek MBD değerleri pozitif kontrol (EPC/DPC) ve negatif kontrol (ENC/DNC) gruplarında bulundu (p

The Antioxidant Effect of Green Tea, Rosemary, and Their Combination on Resin Bond Strength to Bleach Tooth Structures

Objective: This study aimed to evaluate the effect of four experimental antioxidantprotocols on the shear bond strength of a resin-based composite to bleach theenamel and dentin.Materials and Methods: Using extracted bovine incisors, 140 enamel/140 dentinspecimens were prepared. Both enamel and dentin samples were assigned intoseven groups, individually (n=20): ENC/DNC= negative control, EPC/DPC= positivecontrol, EDR/DDR= delayed restoration, ESA/DSA= sodium ascorbate, EGT/DGT=green tea, ER/DR= rosemary and EGTR/DGTR= green tea and rosemary combination.Experimental antioxidant solutions prepared from sodium ascorbate, green tea,or rosemary extracts were applied to the bleached enamel/dentin samples in theESA/DSA, EGT/DGT and ER/DR groups, respectively. The mixture of the green tea/rosemary extract solutions at a 1:1 ratio was applied to the EGTR/DGTR groups toinvestigate possible synergistic antioxidant interaction. The shear bond strength(SBS) test was conducted at a crosshead speed of 0.5 mm/minute. Failure modeswere assessed under a stereomicroscope at x40 magnification. Data were analysedstatistically using Welch-ANOVA and Tamhane post-hoc tests.Results: The lowest and highest mean SBS values were obtained in the positivecontrol groups (EPC/DPC) and negative control groups (ENC/DNC), respectively(p
