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
