A.B.C in clinical endodontics

it mainly concerned about systemic conditions (diseases) such as cardiovascular diseases, bleeding disorders, diabetes, cancer, AIDS, pregnancy, allergies, steroid therapy, infectious diseases etc.

A patient who shows no incentive (motivation)
to maintain good oral hygiene or one who
constantly misses appointments may not be a
good candidate for endodontic therapy

Morphology
• Unusual length
• Unusual shapes
• Unusual numbers (canal or roots)
• Resorptions
• Calcifications
 Previous treatment
• Canal blockage
• Ledge
• perforations
 Location of tooth
• Accessibility
• Proximity to other structures
• Restorability
• Periodontal status

Canal shape: an open apex requires apical losure techniques before obturation
Proximity to other structures ;
eg..mental foramen or Maxillary sinus
Restorability ;
decay into the furcation may render a tooth untreatable

general process and sequence:
• Management of acute pulp or periodontal pain.
• Oral surgery for extraction of unsalvageable teeth.
• Caries control of deep lesions that may threaten the pulp.
• Periodontal procedures to manage soft tissue.
• Endodontic procedures for asymptomatic teeth with necrotic pulps and surgical treatment or re-treatment of failing root canals.[/left
