Preliminary Microleakage Comparison of Bulk-Fill Restoratives and Preformed Metal Crowns in Pulpotomized Primary Molars.

The purpose of this in vitro study was to compare the microleakage of bulk-fill restoratives to the gold standard, preformed metal crowns (PMCs), in pulpotomized primary molars. Fifty-four extracted primary molars were selected, ensuring three intact walls and at least two-thirds root length. After caries removal and pulpotomy procedures, intermediate restorative material (IRM) was placed in the pulp chambers.
