Circa 7.3million amalgam restorations were included, of which 2.5million had a re-intervention at 15 years. Kaplan Meier Analysis revealed that, overall, 41% of amalgam restorations had not required a re-intervention at 15 years.
Larger restorations survived less well to re-intervention than small restorations, with similar findings for time to extraction of the restored tooth. The placement of a dentine pin in restorations resulted in poorer performance of restorations.
Amalgam restorations in younger patients performed better than those in older patients, both in terms of time to re-intervention and time to extraction of the restored tooth.
