The Filtek™ LS Low Shrink Posterior Restorative System from 3M ESPE combines the lowest-shrinking silorane-based composite with a dedicated, two-step, self-etching bonding system: 3M ESPE LS System Adhesive Self-Etch Primer and Bond. It offers excellent bond strength to enamel and dentin, and is the one and only adhesive formulated to provide optimal bonding with such an extraordinarily low-shrinking composite.
