Best treatment sequence for tooth #19 with symptomatic irreversible pulpitis + symptomatic apical periodontitis:

  1. Extraction, follow-up as needed
  2. RCT, PFM crown, periodontal therapy
  3. Periodontal therapy, RCT, PFM crown
  4. RCT, provisional crown, periodontal therapy, PFM crown
Show answer and explanation

Correct answer: D. RCT, provisional crown, periodontal therapy, PFM crown

Correct sequence: RCT (urgent phase) u2192 provisional crown (immediate coronal bracing post-RCT) u2192 periodontal therapy (control phase) u2192 PFM crown (definitive restoration in healthy periodontium). Perio before RCT wastes effort; final crown before perio risks cement failure.
