Accelerated fatigue testing of dentin-composite bond with continuously increasing load

Resin composites are now widely used in direct dental restorations. However, as their use becomes more popular, the occurrence of restoration failure has also become more frequent [1,2]. Clinical studies have shown that, on average, composite restorations have a shorter lifetime than amalgam restorations, with one of the main causes of failure being recurrent caries at the tooth-restoration margin [3 –5]. Maintenance of interfacial integrity is therefore essential for a composite restoration to be durable, and all new composite systems should be assessed for their interfacial strength to ensure acceptable clinical performance.
