Bicuspid

Definition

noun, plural: bicuspids

A tooth having two cusps or projection points; a premolar tooth.


adjective

Having two points, such as bicuspid tooth or bicuspid aortic valve.


Supplement

Bicuspid is located between the canine and molar teeth, and is considered as a transitional tooth. Because it has the properties of both the anterior canines and posterior molars, food can be transferred from canines to bicuspids and finally to molars for grinding, instead of directly from canines to molars.

Adult humans have a total of eight bicuspids: maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar.


Word origin: New Latin bicuspis, bicuspid- : Latin bi-, two + Latin cuspis, sharp point.
