Study Notes
Maxillary Lateral Incisor
- Pulp chamber anatomy is similar to that of the central incisor
- In cross-section, the pulp chamber can be triangular, oval, or round in shape
Maxillary Canine
- Pulp cavity is narrower mesiodistally than labiolingually
- In cross-section, the pulp cavity has a wedge shape
Maxillary Second Molar
- Pulp chamber anatomy is similar to that of the maxillary first molar
- However, the pulp chamber is smaller in mesiodistal section
- In cross-section, the pulp chamber is oval in shape
Mandibular First Premolar
- Mostly has one canal, but two canals are possible
- The shape of the maxillary arch is larger than that of the mandibular arch when the teeth are in maximum intercuspation (maximum bite)
- During maximum intercuspation, the mesiolingual cusp of the maxillary molars occludes with the central fossae of the mandibular molars
This quiz covers the anatomy of the maxillary lateral incisor, including the shape of the pulp chamber and its cross-sectional features.
