Traits for Mand. Central vs. Lateral Incisor

Which statement best describes the symmetry of mandibular central vs. lateral incisors? (facial view)

Centrals are symmetrical; laterals are asymmetrical

How do the proximal contact positions differ between mandibular central and lateral incisors? (facial view)

Centrals: mesial and distal contacts are at the same level (incisal 1/3); Laterals: distal contact more apical than mesial

How do the incisal angles differ between mandibular central and lateral incisors? (facial view)

Centrals: mesioincisal and distoincisal angles are nearly identical; Laterals: distoincisal angle is more rounded

What distinguishes the incisal edges of mandibular central vs. lateral incisors? (incisal and mesial views)

Centrals: incisal edges are straight at right angles; Laterals: incisal edges twist distolingually

Where is the cingulum positioned on mandibular central vs. lateral incisors? (incisal and lingual views)

Centrals: centered; Laterals: distal to center

On mandibular lateral incisors, which marginal ridge appears longer? (lingual view)

Mesial marginal ridge

How does the crown orientation differ between mandibular centrals and laterals? (facial view)

Centrals stand upright on their root; Laterals tip slightly to the distal

Which direction does the incisal edge slope on mandibular lateral incisors? (facial view)

Cervically toward the distal
