1. Pulp capping materials

2. Requirements for capping materials
Thermal isolator.
Non-changing in consistency and bulk.
Introduced into a deep cavity without pressure.
Not toxic to the pulp.

3. Calcium hydroxide (dycal)
Short comings
Ca(OH)2 will break down when acid etchant used,
Failed under amalgam condensation.
Dissolve after long term restoration.
There will be tunnel defects in reparative dentine.

4. Visible light activated dycal
20-40 sec. curing.
We have more time for proper adaptation,

5. Total etch procedure (bonding agent)
Short coming
Opening dentinal tubules
Many modern bonding are toxic.
May inhibit pulp T-lymphocyte.
Increasing pulp-temperature by the polymerizing light.

6. Zinc oxide eugenol
Pulp contact with ZOE can interfere with cellular proliferation ending in necrosis.
Interferes with composite polymerization.
Excellent thermal isolation.

7. Tricalicium phosphate and Hydroxyapatite.
Maintenance pulp vitality.
Osteodentin and tubular dentin formation.

8. MTA (mieral trioxide aggregate)
Surgical, root canal filing, direct pulp capping, root perforation and apexification.
Gray powder mixed with sterile water.
Ph= 12.5

9. Co2 laser Good success rate Sterilization and scar formation
Direct stimulation of dentin formation

10. Ledermix
Steroid+tetracyclin
Anti-inflammatory +bacteriostatic

11. Biodentin
BIOACTIVE DENTIN SUBSTITUTE: • For crown and root indications • Promotes remineralization of dentin • Preserves pulp vitality and promotes pulp healing • Replaces natural dentin with the same mechanical properties
