🛠 Root Canal Treatment Success Prediction Simulator

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.
