Study Notes
Permanent Maxillary Premolars
- There are four maxillary premolars, two in the right and two in the left, located posterior to the canines and anterior to the molars.
- Maxillary premolars have shorter crowns and shorter roots compared to maxillary canines.
- The maxillary first premolar is larger than the maxillary second premolar.
- Premolars succeed deciduous molars and are named so because they are anterior to molars in permanent dentition.
Characteristics
- Labial aspect of canine and buccal aspect of premolar are similar in form.
- Premolars and molars are used to grind food, while canines are used to tear food.
- Premolars are positioned in the center of the dental arch.
Common Features of Posterior Teeth
General Characteristics
- Greater relative facio-lingual measurement compared to mesio-distal measurement.
- Broader contact areas.
- Contact areas are nearly at the same level.
- Less curvature of the cervical line mesially and distally.
