Left Lower Lateral Secondary Incisor Tooth (Dens incisivus lateralis mandibularis sinister)
Educational content only — not medical advice.
Anatomy
The left lower lateral secondary incisor tooth (FDI #32, Universal #23) is slightly larger, wider, and longer than the mandibular central incisor. Positioned between the central incisor and canine in the mandible, its crown displays a slight distal tilt on its single root with distinct longitudinal root depressions, contributing to incision and anterior occlusion.
Clinical notes
Frequently involved in mandibular anterior crowding when arch length discrepancies exist; endodontic access requires careful search for a frequent second canal (lingual canal) in its narrow root.
