Maxillary second premolars

• Maxillary second premolars usually have one root
• The height difference between the lingual and buccal cusps is much less significant
• Cusp tips are closely located, contributing to a narrow occlusal table
• Facially, the buccal ridge is less prominent in the maxillary second premolar compared to the first premolar
• The cervical region is wider and the root is longer compared to maxillary first premolars
• The root has a shallow developmental depression
• The marginal ridges are thicker compared to the first premolars
• Buccolingual convergence is not as obvious compared to the maxillary first premolar
• The central developmental groove is shorter in maxillary second premolars
