Restoration failure · Permanent posterior teeth (molars/premolars) receiving direct restoration
There was no statistically significant difference in failure risk between composite resin and amalgam restorations in permanent posterior teeth (pooled RR 0.96, 95% CI 0.68 to 1.34; 13 studies; not GRADE-rated, with very high heterogeneity, I2 = 97%).
