Abstract

<p>The purpose of this study was to investigate the effect of colloidal platinum nanoparticles on dentin bond strength. One bonding system was tested CLEARFIL Universal Bond (CUB) and tested following two kinds as a surface treatment agent: 1 K ETCHANT Syringe (Ech), 2 the thing which mixed with phosphoric acid by a colloidal platinum nanoparticles (CPN). Dentin surfaces were subjected to one of the following treatments: NE(only CUB), E(Ech and CUB), CPN-E(CPN and CUB). After resin composite build-up, each specimen was sectioned after water storage at 37°C for 24 hours to obtain beams with a bonded area of 1 mm2. µTBS test was performed using half of the beams from each group. Rest of the beams were tested after 6 months. The bond strength did not decrease only CPN-E in six months later. This study indicated that adhesion long-term durability is provided when use CUB and CPN together.</p>
