Pre-molar Flashcards
Mesial cusp ridge of the buccal cusp is longer than the distal cusp ridge.
Maxillary first premolar
Has a nonfunctioning lingual cusp.
Mandibular first premolar
Two premolars that most frequently have a groove crossing the mesial marginal ridge or one groove just lingual to it.
Maxillary first premolar
Mandibular first premolar
Has a depression in the cervical one third of the mesial side of the crown and root.
Maxillary first premolar
Maxillary premolar that has the longer sharper buccal cusp.
Maxillary first premolar
Largest maxillary premolar.
Maxillary first premolar
Mandibular premolar with the longest and sharpest buccal cusp.
Mandibular first premolar
Maxillary premolar that is most symmetrical (occlusal view).
Maxillary second premolar
Two premolars without a central groove.
Mandibular first premolar
Crowns tipped lingually with respect to the root axis line (proximal view).
Mandibular first premolar
Mandibular second premolar (two-cusp type)
Mandibular second premolar (three-cusp type)
From buccal view, crown is tipped distally from the root axis.
Mandibular first premolar
Mandibular second premolar (two-cusp type)
Mandibular second premolar (three-cusp type)
Mesial marginal ridge is more cervically located than its distal marginal ridge.
Mandibular first premolar
Has no transverse ridge.
Mandibular second premolar (three-cusp type)
