Sealing of amalgam margin defects

A.Sealing of amalgam margin defects: were acid etched with 35% phosphoric acid for 15 seconds. A resin-based sealant (Clinpro Sealant, 3MESPE) was applied over the defective area. The sealant was polymerized with a photocuring unit (Curing Light 2500, 3M ESPE) for 40 seconds. Rubber dam isolation was used for this procedure. All treatments were applied by the same clinician. B.Replacement Group: The clinician totally removed and replaces the defective restoration with a new amalgam (Tytin, Kerr Corporation, Orange, CA, USA). Rubber dam isolation was used for this procedure. All treatments were applied by the same clinician. C.Control Group: The defective restorations did not receive any treatment.
