Abstract

Amaç: Bu çalışmada, farklı hızlandırıcı ilave edilen Mineral Trioksit Agregat’ın (MTA) kompozite farklı sertleşme sürelerinde makaslama bağlanma dayanımının (MBD) değerlendirilmesi amaçlanmıştır.
Gereç ve Yöntemler: Merkezi boşluklara sahip 120 adet akrilik blok 4 ana gruba ayrıldı. 1. grup (kontrol); sadece MTA, 2, 3 ve 4. grup ise sırasıyla %10 kalsiyum klorür (CaCl2), %23,1 kalsiyum laktat glokonat (CLG) ve %15 disodyum hidrojen fosfat (Na2HPO4) ile karıştırılmış MTA içermektedir. Her grup 2 saat 45 dakika , 24 saat ve 96 saat sertleşme süresine göre 3 alt gruba ayrıldı. Bekleme süreleri tamamlandıktan sonra adeziv sistem (Clearfil SE Bond, Kuraray) ve kompozit rezin (Clearfil Majesty, Kuraray) işlemleri tamamlanan örneklere evrensel test cihazında MBD testi uygulandı. Elde edilen verilerinin karşılaştırmasında, tek yönlü varyans analizi (ANOVA) ve Tukey HSD testleri kullanıldı.
Bulgular: Hızlandırıcısız MTA en yüksek ortalama MBD değeri sergiledi. Hızlandırıcısız MTA, hızlandırıcı olarak CLG ve Na2HPO4 eklenen MTA ile kıyaslandığında aralarındaki fark anlamlı bulundu (p<0.0001). Başlangıç sertleşme süresinde alt gruplar arasında istatistiksel olarak anlamlı farklılık gözlenmedi (p>0,05), diğer sertleşme sürelerinde fark anlamlı bulundu (p<0,05). MTA’ya hızlandırıcı olarak CLG ve Na2HPO4 ilavesinin tüm sürelerde MBD değerlerini azalttığı, CaCl2 ilavesinin ise 96 saatin ardından MBD değerini anlamlı olarak yükselttiği gözlendi.
Sonuç: MTA içerisine hızlandırıcı eklemek MBD değerini düşürmektedir. Ancak MTA’ya hızlandırıcı olarak %10 CaCl2 eklemek 96 saatin ardından yapılacak restoratif işlemlerde pozitif bağlantı sonuçları ortaya çıkarabilir.

Does adding accelerators to Mineral Trioxide Aggregate affect the shear bond strength?

Abstract

Background: It was aimed to evaluate the shear bond strength (SBS) of Mineral Trioxide Aggregate (MTA) with different accelerators to the composite resin at different setting times.
Methods: One hundred-twenty acrylic blocks with central cavities were divided into 4 groups. Group 1 (control); only MTA, groups 2, 3 and 4 contain MTA mixed with 10% calcium chloride (CaCl2), 23.1% calcium lactate gluconate (CLG) and 15% disodium hydrogen phosphate (Na2HPO4), respectively. Each group was divided into 3 subgroups according to the setting time of 2 hours 45 minutes, 24 hours and 96 hours. After the adhesive system (Clearfil SE Bond, Kuraray) and composite resin (Clearfil Majesty, Kuraray) processes were completed, SBS test was applied on a universal testing machine. Data were analyzed using one-way ANOVA and Post Hoc Tukey tests (p<0.05).
Results: MTA group (without accelerator) had the highest SBS values. When MTA (without accelerator) group was compared with groups of CLG and Na2HPO4 added to MTA as accelerators, the differences between them were significant (p<0.0001). There were no statistically significant differences between the subgroups in the initial setting time (p>0.05), the differences were significant in the other setting times (p<0.05). The addition of CLG and Na2HPO4 as accelerators to MTA decreased the SBS values at all setting times, while the addition of CaCl2 significantly increased the SBS value after 96 hours.
Conclusion: Adding accelerators to MTA reduces the SBS values. However, adding 10% CaCl2 to MTA as an accelerator may reveal positive bonding results in restorative procedures after 96 hours.
