Anatomy

The Mandibular Second Premolar typically has a more complex structure than the Mandibular first premolar. It usually has two cusps - one buccal and one lingual, with the buccal cusp being the larger. The occlusal table is generally broader than that of the first premolar.

Function

The primary function of the Mandibular Second Premolar, like other premolars, is to assist in the chewing and grinding of food. Its position in the mouth allows it to play a key role in the initial breakdown of food particles.

Development

The development of the Mandibular Second Premolar begins around the age of 10, with the tooth typically erupting into the mouth between the ages of 11 and 12. This tooth replaces the second deciduous molar, which is shed during childhood.

Clinical Significance

The Mandibular Second Premolar is often involved in dental procedures such as root canal therapy, dental extraction, and dental restoration. Its complex anatomy can make these procedures more challenging.
