Presentation Transcript

  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

  12. Thank you
