Statement Of Problem:
Postoperative sensitivity is sometimes reported to be a clinical problem after placement of silver amalgam restorations.
Purpose:
This study compared postoperative sensitivity of Class 5 caries restored with amalgam restorations and Copalite or DentinBloc cavity liners.
Material And Methods:
At least 1 pair of amalgam restorations were placed in each of 16 patients and tested for sensitivity at 5 time periods.
Results:
Sensitivity was significantly less with DentinBloc cavity liner (P < .05) at 24 hours, and 2 and 4 weeks. There was a directional but nonsignificant effect (P > .05) in favor of DentinBloc cavity liner at 1 and 16 weeks.
Conclusion:
DentinBloc cavity liner was more effective than Copalite cavity liner in reducing sort term postoperative sensitivity for amalgam restorations.
