Microleakage of castings cemented with glass-ionomer cements
Operative Dentistry
|January 1, 1990
Abstract:
When metal copings were luted to prepared, extracted teeth with KetacCem, ChemBond, TempBond, and zinc-oxide-eugenol (ZOE), only thermocycled ZOE exhibited severe leakage. It appears unlikely that postcementation microleakage is the cause of tooth sensitivity associated with the use of glass-ionomer cements.
