Amaç: Bu çalışmanın amacı yaşlandırılmış kompozit reçinelerin farklı adeziv ajanlar kullanılarak
yapılan onarımlarında ilgili materyallerin bağlanma dayanımlarında mikromakaslama kuvvetlerinin
etkisinin değerlendirilmesidir.
Gereç ve Yöntem: Kompozit reçine esaslı 8x5 mm boyutlarında 60 adet disk şeklinde örnek
hazırlandı. Örneklerin bağlanma dayanımları mikromakaslama test cihazında ölçüldü ve elde edilen
veriler istatistiksel olarak değerlendirildi (p < 0,05).
Bulgular: Adeziv ajanın ve yaşlandırma yönteminin sonuçlar üzerinde istatistiksel olarak etkinliği
saptandı (p < 0,001). Yaşlandırma işlemi uygulanmayan gruplardan 2 aşamalı self-etch adeziv ajan
grubuyla tek aşamalı total-etch adeziv ajan grubu arasında fark bulunamazken diğer gruplar arasında
istatistiksel fark bulunmaktadır (p < 0,05). Yaşlandırma yapılan gruplardan 2 aşamalı self-etch adeziv
ajan grubuyla tek aşamalı self-etch adeziv ajan grubu arasında farklılık bulunmaktayken (p < 0,05); diğer
gruplar arasında istatistiksel fark bulunmamaktadır.
Sonuç: Yaşlanmış kompozit reçinelerin onarımları mikromakaslama kuvvetlerine dayanım açısından
değerlendirildiğinde, iki aşamalı self-etch ve total-etch adeziv ajanlar, tek aşamalı self-etch adeziv
ajanlara göre daha yüksek bağlanma dayanım değerleri göstermiştir.
