The microtensile strength of bonding resins

Abstract

Background: The purpose of this study was to determine the effect of water on the tensile strength of three bonding resins (All Bond 2, Scotchbond Multi-Purpose Adhesive, Clearfil LB Bond) and a low viscosity resin composite (Protect Liner F) after 1, 7, 28, 84 and 168 days of storage. Methods: Cylinders of bonding resin 2.4±0.2mm diameter and 9.5mm long were made and stored at 37°C for 24 hours. The specimens were milled into dumb-bell shapes and stored in either air or water at 370C. Five specimens of each material were stressed in tension after the specified storage times at a crosshead speed of 1mm/min in a testing jig attached to a universal testing machine. The mean tensile strengths o..
