Crown of Mandibular Second Molar Tooth

Description

The crown (anatomical crown) is the superior portion of the mandibular second molar tooth that is covered by enamel. It is separated from the root by the cervical line and consists of five surfaces (buccal, lingual, mesial, distal, and occlusal) and four cusps.

The clinical crown is a term used to describe the superior portion of a mandibular tooth that is not covered by gingiva when viewed in the oral cavity.
