Dycal Isolation

Armamentarium:

1. Dycal

2. Needle Tip Centrix syringe and tip

3. Mixing pad and spatula



7/39

Dycal Technique

Stuff Dycal into the needle tip cap, place

plunger, load into the syringe

Squirt around the clamp to seal gaps and

leaks

Case Pearl of Wisdom

Maintain enamel walls if possible

throughout endo treatment

Place the Dycal Barrier then remove

unsupported enamel.

When to use Dycal?

To plug simple gaps in the dam.

To form a matrix, with or without a band

and wedges when no extensive

condensation force is required (composite)



17/39

Copper Band Matrix Technique

Used for more severely broken down crowns and

when heavy condensation force is required

(amalgam)



18/39

Materials

Dead Soft Copper Bands (available in any

major supply catalogue)

C & B scissors

Dycal/Centrix Syringe (as mentioned

before)

Choose a band that is slightly larger

than the cervical circumference ofthe tooth

Once Endo finished:

1. Replace fresh dam2. Fit Cu Band

3. Secure with Dycal

4. Place Core

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.



38/39

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.
