Abstract:
Twelve prefabricated posts were cemented in extracted teeth with zinc phosphate cement, 14 with resin cement after the canals were acid etched and 14 with zinc phosphate cement after acid etching. After thermocycling, specimens were subjected to a straight-line tensile force. The posts cemented with resin cement had significantly higher tensile strength than those cemented with the two zinc phosphate cement treatments.
