Abstract

This study investigated the effectiveness ofnew development self-etching adhesive on the shearbond strength of one layer, two layer and threelayer applications to dentine. 45 extracted humanmolar teeth were subjected by wet grinding with360-grit silicon carbide paper and then exposeddentine surfaces were prepared with three differentapplication methods by Adper Prompt L-Pop APP . One layer application Control : APP wereapplied for 15 seconds on the specimens and gentlyair dried for 3 seconds and polymerized with halogen light for 10 seconds n=15 . Two layer application: The specimens were prepared as a duplicate ofthe one layer application n=15 . Three layer application: The specimens were prepared as triple ofthe one layer application n=15 . Composite Z250 cylinders 4 mm diameter, 2 mm high were polymerized with 40 seconds on the self-etching treatedall dentin surfaces. The specimens were stored at37°C for 24 h prior to testing. Cemented specimenswere subjected to shear loading 0.5 mm/min untilfracture using a universal testing machine Llyod .Statistical analysis was done with one-way analysisof variance ANOVA and Duncan test. Two layerapplication had significantly higher bond strengths 10.6 ± 2.1 MPa on dentine P

SELF-ETCH ADEZİVİN TEK KAT VEYA ÇOK KAT UYGULAMASININ MAKASLAMA DİRENCİ ÜZERİNE ETKİSİ

Abstract

Bu in-vitro çalışmanın amacı, yeni geliştirilenbir self-etch adezivin dentin yüzeylerine bir kat, ikikat ve üç kat uygulamasının makaslama direnciüzerine etkilerini incelemektir. 45 adet daimi molardişlerin mine dokuları 360-grit zımpara ilekaldırıldıktan sonra, ortaya çıkan dentin yüzeylerine Adper Prompt L-Pop APP üç farklı tabakaolarak uygulandı. Tek kat uygulaması Kontrol :Örneklere APP 15 saniye süre ile sürüldü 3 saniyehava sıkıldı ve 10 saniye halojen ışık ile polimerizeedildi n=15 . İki kat uygulaması: Örneklere ikidefa üst üste tek kat uygulaması yapıldı n=15 . Üçkat uygulaması: Örneklere üç defa üst üste tek katuygulaması yapıldı n=15 . Tüm self-etch adezivuygulanmış örneklere 2 mm uzunluğunda ve 4 mmgenişliğindeki silindir teflon kalıp içerisine kompozit rezin Z250 yerleştirildi ve 40 saniye polimerize edildi. Örnekler 24 saat 37 °C’ de distile suiçerisinde bekletildi. Örneklerin makaslama dirençlerini tespit etmek için her örnek instron universaltest makinesine Lloyd yerleştirildi ve dakikadakihızı 0.5 mm/dak olacak şekilde, örneklerekırılıncaya kadar yük uygulandı. İstatistiksel analiztek yönlü varyans analizi ANOVA ve Duncan testiile yapıldı. İki kat APP uygulaması ile en yüksekmakaslama direnci sonuçları 10.6 ± 2.1 MPa eldeedildi P0.05 . Bu in vitro çalışmasonuçlarına göre yeni geliştirilen APP’ un iki katuygulaması ile dentinde iyi bir bağlanmasağlanmıştır
