Abstract

Effect of
ultrasonic and sonic activation on the push-out bond strength of self-adhesive
resin cement

ABSTRACT

Background:
This study aims to evaluate the bond strength of SARC to the root canal dentin
through the use of ultrasonic and sonic activation. Methods: Thirty-six mandibular premolar teeth were used. After
preparation-irrigation-obturation procedures post space preparation was
completed with the drill incident to post system used. Specimens were divided
randomly into three groups according to resin cement activation (n=12): No
activation (Control), Ultrasonic activation (UA), Sonic activation (SA). Fiber
posts were seated and resin cement polymerized. Six slices, 1-mm thick, were
obtained from each specimen. A push-out test was performed to slices two, four,
and six. Data were analyzed statistically with Kruskal-Wallis and Mann-Whitney
U tests. Results: A significant
difference was found between activation methods (p<0.05). The control group
showed significantly better bond strength values than the ultrasonic and sonic activation
groups. Root regions had no significant effect on bond strength (p>0.05). Conclusion: Both ultrasonic and sonic
activation of SARC could have negative effects on the bond strength.

 Ultrasonik ve sonik aktivasyonun
self-adeziv rezin simanın itme bağlanma dayanımına etkisi

ÖZET

Amaç: Bu
çalışmanın amacı ultrasonik ve sonik aktivasyon kullanımının self adeziv rezin
simanın kök kanal dentinine olan bağlanma dayanımına etkisinin
değerlendirilmesidir. Gereç ve
Yöntemler: Bu çalışma için 36 adet mandibular küçük azı dişi kullanıldı.
Kök kanallarının şekillendirilmesi, irrigasyonu ve doldurulmasının ardından
post boşluğu preparasyonu yapıldı. Örnekler rezin siman aktivasyon yöntemine
göre 3 gruba ayrıldı (n:12): Aktivasyon yok(Kontrol), Ultrasonik
aktivasyon(UA), Sonik aktivasyon (SA). Ardından fiber postlar yerleştirildi ve
rezin siman polimerize edildi. Her bir örnekten yaklaşık 1 mm kalınlığında 6
yatay kesit alındı. Koronalden 2, 4 ve 6. kesitlere itme testi uygulandı.
Veriler Kruskal-Wallis ve Mann-Whitney U testleri ile istatistiksel olarak
analiz edildi. Bulgular:  Aktivasyon metotları arasında istatistiksel
olarak fark bulundu (p<0.05). Kontrol grubu, aktivasyon yapılan gruplara
göre istatistiksel olarak daha iyi bağlanma değerleri gösterdi. Kökün farklı
bölgelerinde bağlanma dayanımı benzerdi. (p>0.05) Sonuç: Ultrasonik ve sonik aktivasyon yöntemlerinin self-adeziv
rezin simanın bağlanma dayanımı üzerine olumsuz etkileri olabilir.

Anahtar kelimeler: bağlanma dayanımı; self-adeziv rezin siman; sonik aktivasyon; ultrasonik
