Conclusion:
1. Dycal can be used to quickly seal a dam.
2. Dycal can be used as a matrix for simple cores(primarily composite)
3. Cu Bands provide rigidity and maintain contours
during compaction of Ag.

Conclusions4. Cu Bands can be used to enhance the isolation of
coronally compromised teeth during endo Tx.
5. A combination of Dycal , Cu Bands, Matrix
Bands and Wedges can be used to build up and
isolate virtually any tooth that is restorable.
