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

Co 2 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
