One-year clinical evaluation of bonded amalgam restorations
Article Abstract:
Bonded amalgam fillings do not appear to offer advantages over nonbonded amalgam fillings. Dentists thought that bonding would decrease the incidence of marginal fractures, which would extend the life of the filling, and reduce tooth sensitivity. Twenty-six patients requiring more than one filling had 100 fillings installed in pairs, one bonded and one unbonded. Similar percentages of patients reported sensitivity in the unbonded teeth as in the bonded teeth at the end of one to two weeks. Similar percentages had marginal fractures in the unbonded teeth as in the bonded teeth at the end of one year. A longer follow-up period might show differences so no conclusions can be reached as yet about marginal fractures. In addition, the bonding compound tended to cause technical problems with installing the filling. Because bonding appeared to offer no advantages and had some drawbacks, its use is not currently recommended.

One-visit composite and amalgam bonding for strong, aesthetic posterior restorations
Article Abstract:
A combination of composite resins and amalgam bonding to restore posterior teeth and the creation of temporary crowns with leftover impression material may save time for dentist and patient. Combining composite resin with amalgam strengthens resin while providing an aesthetic appearing restoration, and can be completed in one office visit. The composite and amalgam bonding restorations may be used on teeth that have had root canals, before crowns are placed. Temporary crowns may be created quickly by using leftover dental impression material. Temporary crowns may be acceptable replacements until the permanent crown can be created.

Microleakage of amalgam alloys: an update
Article Abstract:
The mix of metals in amalgams used for tooth fillings may determine the amount of microleakage, the flow of fluids and bacteria between filling and tooth. The examination of 33 manufactured amalgams yielded a variety of microleakages, dependent on the materials used. Spherical particle alloys leaked the most. Adding one percent more mercury to the alloys markedly decreased microleakage, potentially reducing post-operative sensitivity in patients.
