Study Notes
Characteristics of Mandibular Premolars
- Mandibular second premolars typically have three well-formed cusps: one large buccal cusp and two smaller lingual cusps.
- The lingual surface of the mandibular first premolar is characterized by the presence of a mesiolingual developmental groove.
- The buccal surfaces of all mandibular posterior teeth have a convexity and a characteristic location of the crest of contour.
- The distal marginal ridge of the mandibular first premolar is higher than the mesial marginal ridge, with less inclination lingually, forming the mesial and distal fossae.
- The most common type of mandibular first premolar features a mesiolingual developmental depression and groove.
