Premolar with occlusal grove pattern of a Y is

Mandibular P1
Mandibular P2
Maxillary P1
Maxillary P2

The correct answer is: Mandibular P2

A premolar tooth with an occlusal groove pattern of a Y is indicative of a mandibular P2. This is because mandibular P1 teeth typically have a single-rooted structure and maxillary P1 teeth usually have a more complex occlusal pattern. Additionally, maxillary P2 teeth often have a larger occlusal surface compared to mandibular P2 teeth. Therefore, the answer B is the most suitable choice as it matches the characteristics of a premolar with a Y-shaped occlusal groove pattern.
