Placement and replacement of resin-based composite restorations in Italy

Abstract

The use of resin-based composite restorations, the reasons for failure, and the longevity of these restorations have been surveyed in 62 Italian private practices. Almost two-thirds of the 1025 restorations inserted were class 3 and 5 restorations, while 18% were class 1 and 2 restorations. Secondary caries was the most common reason reported for replacement of resin-based composite restorations (44%), followed by discoloration (21%), and bulk and margin fracture (14%). The age of restorations needing replacement was reported for 53% of the sample. The median longevity in this sample was calculated to be 3.3 years.
