Dental amalgam remains a widely used restorative material.
Dentists routinely face clinical situations requiring decisions whether to replace or repair an amalgam restoration. Multisurface amalgam restoration repair may be preferred when small cuspal or restoration fractures occur. This study's purpose was to compare five amalgam repair techniques. Six groups of fifteen 5 mm x 5 mm x 20 mm amalgam beams of Tytin amalgam were condensed in a prefabricated split mold. The control specimens consisted of intact 20 mm length beams.
