Mandibular Incisors: The Most Underestimated Teeth in Endodontics
Mandibular incisors are often perceived as “simple single-canal teeth.”
Radiographically, they appear narrow, straight, and uncomplicated.
Clinically — they are not.
These teeth represent one of the most frequently underestimated anatomical challenges in endodontics.
📊 What Does the Evidence Say?
Large CBCT-based and systematic review studies consistently demonstrate:
• Single canal (Vertucci Type I) → ~55–70%
• Two canals merging into one (Type II) → ~20–35%
• 1–2–1 configuration (Type III) → ~5–10%
• Two completely separate canals to two foramina (Type IV) → ~1–3%
• Complex configurations (Type V, VI, VII) →
