Can you advise me on a posterior composite that produces minimal marginal discoloration over time?

THE DENTALADVISOR has just completed a 3-year clinical study of 3M ESPE Filtek LS Low Shrink Posterior Restorative System (3M ESPE). 148 Class I (36%) and Class II (64%) were placed. The results show that after three years, all scores were at least 4.96 on a 0-5 point scale. Resistance to marginal discoloration was one of the categories, along with esthetics, resistance to fracture, wear resistance, and lack of post-operative sensitivity. It is an excellent composite, but you must be aware that because it is low shrink, it has a different chemical make-up and therefore has its own bonding agent that you must use according to their directions.
