Root Canal

This page explains root canal treatment from pulpal and periapical diagnosis through treatment planning, endodontic procedures, coronal restoration, follow-up, and long-term outcomes. It covers reversible and irreversible pulpitis, pulpal necrosis, apical periodontitis, root canal indications, case selection, treatment timing, prognosis, postoperative symptoms, endodontic complications, retreatment, and referral decisions.

The content outlines how clinicians assess endodontic disease, distinguish conditions that may be managed conservatively from those requiring root canal treatment, and determine when treatment, monitoring, retreatment, extraction, or referral is appropriate. It provides an overview of the complete endodontic pathway and links to detailed evidence-informed articles on diagnosis, treatment planning, procedural complications, restoration, and outcome assessment.

🦷 Clinical Reasoning Hub

Root canal treatment is indicated when pulpal or periapical disease is unlikely to recover predictably without endodontic intervention. In practice, the decision depends on the clinical diagnosis, tooth restorability, periodontal support, and the expected long-term prognosis.

Root canal treatment is a sequence of clinical decisions rather than a single procedure; long-term success depends on diagnosis, treatment planning, restoration, and structured follow-up.
Quick clinical questions and answers for root canal treatment

Does this tooth need RCT?

Diagnose biology, not pain.

Is the pulp recoverable?

Consider symptoms, vitality testing, and clinical context.

Is the tooth restorable?

Assess structure before treatment.

Should antibiotics be used?

Only when clinically indicated.

RCT or extraction?

Base the decision on biologic and restorative prognosis.

Is retreatment needed?

Identify the cause before intervening.

Root canal treatment follows a sequence of linked decisions. The pathway below reflects how a typical endodontic case moves from presentation to diagnosis, treatment, restoration, healing, and long-term review.
