Study Notes
Maxillary Lateral Incisor
- Resembles the maxillary central incisor in function, form, and anatomy, but is smaller in all dimensions except root length.
- Crown is more rounded, shorter, and narrower mesio-distally than the maxillary central incisor.
Principle Identifying Features
- Mesio-incisal angle is acute, and disto-incisal angle is more rounded.
- Single root with a tapered, distally curved, pointed apex.
- Lingual fossa is more concave than that of the maxillary central incisor.
Labial Aspect
- Crown is shorter and narrower than that of the maxillary central incisor, but the root is as long or longer.
- Labial surface of the crown is more convex than that of the maxillary central incisor.
- Mesial outline resembles that of the maxillary central incisor with a more rounded mesio-incisal angle.
- Crest of curvature (contact point) is located between the middle and incisal thirds mesially.
- Distal outline is more rounded, with the crest of curvature (contact point) at the center of the middle third.
- Root tapers evenly and curves distally at the apex.
