Maxillary second premolar

The Maxillary Second Premolar is one of the teeth located in the upper jaw, also known as the maxilla. It is the eighth tooth from the midline and is typically the sixth tooth to erupt in the oral cavity.

Anatomy

The maxillary second premolar typically has two cusps, one buccal and one palatal. The buccal cusp is usually larger than the palatal cusp. The tooth has a single root, but it may sometimes have two roots. The crown of the tooth is wider buccolingually than mesiodistally.

Function

The primary function of the maxillary second premolar is to assist in the mastication of food. It works in conjunction with the other premolars, molars, and canines to grind and crush food into smaller, more digestible pieces.

Clinical Significance

The maxillary second premolar is often involved in dental procedures such as root canal therapy, dental extraction, and dental restoration. It is also a common site for the development of dental caries and periodontal disease.
