The premolar teeth or bicuspids are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant, making eight premolars total in the mouth. They have at least two cusps. Latin is an ancient Indo-European language originally spoken in the region around Rome called Latium. ...

In oral anatomy, the canine teeth, also called cuspids, dogteeth, fangs, or (in the case of those of the upper jaw) eye teeth, are relatively long, pointed teeth, evolved (and used, in most species where they remain prominent) primarily for firmly holding food in order to tear it apart, and...

The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. The maxillary first premolar is the tooth located laterally (away from the midline of the face) from both the maxillary canines of the mouth but mesial (toward the midline of the face) from both maxillary second premolars. ... The maxillary second premolar is the tooth located laterally (away from the midline of the face) from both the maxillary first premolars of the mouth but mesial (toward the midline of the face) from both maxillary first molars. ... The mandibular first premolar is the tooth located laterally (away from the midline of the face) from both the mandibular canines of the mouth but mesial (toward the midline of the face) from both mandibular second premolars. ... The mandibular second premolar is the tooth located distally (away from the midline of the face) from both the mandibular first premolars of the mouth but mesial (toward the midline of the face) from both mandibular first molars. ...

There is always one large buccal cusp, especially so in the mandibular first premolar. The lower second premolar may, at times present with two lingual cusps.

Premolar teeth by definition are permanent teeth distal to the canines preceded by deciduous molars. In primitive mammals there are four premolars per quadrant. The most mesial two have been lost in New World monkeys, apes, and humans. Paleontologists refer to human premolars as Pm3 and Pm4. In zootomy, several terms are used to describe the location of organs and other structures in the body of bilateral animals. ...
