Left Lower Central Secondary Incisor Tooth (Dens incisivus centralis mandibularis sinister)
Educational content only — not medical advice.
Anatomy
The left lower central secondary incisor tooth (FDI #31, Universal #24) is the smallest and most symmetrical tooth in the human permanent dentition. Anchored in the anterior mandible, it presents a delicate chisel-shaped crown with a straight horizontal incisal edge and a single narrow mesiodistally compressed root, functioning to shear food during biting.
Clinical notes
Due to proximity to the submandibular and sublingual salivary duct orifices, the lingual surfaces of lower central incisors accumulate salivary calculus faster than any other teeth, necessitating regular periodontal scaling.
