Longitudinal Results of a 10-years Clinical Trial of Sealed Margin Failures of Amalgam Restorations
In Brief
An observational study evaluating Sealing of amalgam margin defects for Dental Caries Secondary to Acquired Defects of Tooth Structure. Completed, enrolled 32 participants across 1 site.
Detailed Summary
* Assess the effectiveness of sealing localized marginal defects of amalgam restorations that were initially scheduled for replacement of restorations. * The hypothesis was that sealed defective margins of the amalgam restorations shows similar performance than replacement amalgam restorations.

Comparison between sealing of amalgam margins defects, replacement and non treated groups.
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.
