Study Notes
Permanent Maxillary Central Incisor
- Maxillary central incisors are the widest anterior teeth mesio-distally (labial or lingual surface) and larger than maxillary lateral incisors and mandibular incisors.
Characteristics
- With age, maxillary central incisors wear off, revealing a straight incisal outline.
- The cervical outline of the crown follows a semi-circular direction, curving towards the root.
- A line drawn through the center of the root and crown tends to parallel the mesial outline of the crown and root.
Lingual Aspect
- The cervical outline on the lingual aspect curves incisally more than any surface on any tooth, by approximately 3-4 mm.
