A 5-year study comparing a posterior composite resin and an amalgam

J Prosthet Dent. 1990 Nov;64(5):523-9. doi: 10.1016/0022-3913(90)90121-r.

Abstract

Eighty class I and class II light-cured posterior composite resin restorations were compared with 43 class I and class II amalgam restorations during a 5-year period after placement. The results of this clinical study showed that both materials were satisfactory during the time period and that the only significant statistical differences are a poorer marginal integrity for the amalgam and a greater wear rate for the composite resin.
