Pulp capping materials

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

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.

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

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.

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

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

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

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

Ledermix Steroid+tetracyclin Anti-inflammatory +bacteriostatic

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
