MİKROGERİLİM BAĞLANMA DAYANIM TESTİ VE SONUÇLARINI ETKİLEYEN ETKENLER

Abstract

One of the most important criteria for clinical success with composite restorative materials is the effectiveness and durability of the bonded interface. Development adhesive restorative materials provide an effective bond to dental tissue and, consequently, offering successful restorative treatment. The main challenge for dental adhesives is to provide an equally effective bond to two hard tissues of different nature. Bonding to enamel is now considered a durable, while bonding to dentin has been inconsistent. Originally, one of the key advantages of the microtensile bond strength test is the possibility to test different types of tooth tissue. Additionally, there are a lot of advantages of microtensile bond testing including, conservation of teeth, evaluation of regional bond strengths possible, more uniform loading, conductive to comprehensive examination of research question on same sample. However several factor effect of the finding of microtensile bond strength test like specimen fixation method to gripping device, mechanical properties of the adhesive and the adherents tested, or specimen shape. Different results could be obtained with any change in these testing variables. The aim of this rewiev was to evaluate the microtensile bond strength test method, different specimen geometries and the current studies that evaluate of the bond strength of dentin bonding agents using this method
