Creating sterile field

• avoid having gaps around tooth to create a seal
• always floss to ensure seal
• check for leakage before proceeding
• caulking agents last resort

Irrigation

• instrumentation produces a smear layer,
  • contains organic and inorganic components
  • dentine, pulp tissue, bacteria
  • 1-2microns thick
  • prevents access to bacteria in tubules
  • prevents sealer penetration
• 
• 

role of root filling

• stop PA tissue fluid from reaching surviving bacteria in root canal
• entombment of surviving bacteria
• barrier between oral cavity and periradicular tissue
