Question: 1 / 1180

Which is the most symmetrical premolar and posterior tooth?

Mandibular 1st premolar

Maxillary first premolar

Maxillary second premolar

The most symmetrical premolar and posterior tooth is the maxillary second premolar. This tooth has a rectangular shape, with a more evenly distributed mesial and distal surfaces compared to other premolars and posterior teeth. Furthermore, the maxillary second premolar typically has two buccal cusps that are of similar size and shape, further contributing to its symmetry. The other options, including the mandibular 1st premolar, maxillary 1st premolar, and mandibular 2nd premolar, all have varying degrees of asymmetry, whether in shape or size of cusps, making them less symmetrical compared to the maxillary 2nd premolar.
