Baseline Lesion Status Sets the Prognosis Floor
A pre-existing lesion lowers the starting odds of full healing.
- −15%: Lesion present (placeholder success delta)
- ~95%: No lesion (placeholder baseline success)
- Radiograph: Detection (placeholder method)
- Larger = slower: Size effect (placeholder healing note)
Why baseline pathology matters
Placeholder: lesion size and chronicity affect healing time.
Placeholder: larger lesions need longer recall intervals.
Mechanical and Chemical Canal Debridement
Thorough cleaning removes infected tissue and bacterial load.
- NaOCl: Irrigant (placeholder solution)
- ±0.5mm: Working length (placeholder accuracy target)
- .04–.06: File taper (placeholder system)
- Bacteria ↓: Goal (placeholder outcome)
Shaping quality drives disinfection
Placeholder: proper shaping enables full-length irrigation.
Placeholder: under-instrumentation leaves residual bacteria.
Filling the Canal System Without Voids
A dense, well-condensed fill prevents bacterial recolonization.
- Gutta-percha: Material (placeholder standard)
- Minimal: Void tolerance (placeholder target)
- Epoxy resin: Sealer (placeholder type)
- To terminus: Apical fill (placeholder target)
Density as a success predictor
Placeholder: voids correlate with higher failure risk.
Placeholder: dense fills show stronger long-term outcomes.
The Restoration Above the Filling Matters Too
A leaky crown or filling can reinfect an otherwise good canal.
- Prompt: Timing (placeholder recommendation)
- ↓ with seal: Leakage risk (placeholder effect)
- Crown/Composite: Common restore (placeholder options)
- Coronal leakage: Failure link (placeholder cause)
Coronal seal as the final barrier
Placeholder: seal quality protects the endodontic result.
Placeholder: delayed restoration raises reinfection odds.
Radiographic Healing Tracked Over Recall Visits
Success is confirmed by lesion resolution over months to years.
- 85–95%: Overall success (placeholder literature range)
- 6–12 mo: Recall interval (placeholder schedule)
- Bone infill: Healing marker (placeholder sign)
- Persistent lesion: Failure sign (placeholder sign)
Confirming long-term success
Placeholder: serial radiographs confirm apical bone healing.
Placeholder: combine lesion status and quality for prognosis.
