Which premolar is most likely missing?

Mandibular 1st
Mandibular 2nd
Maxillary 1st
Maxillary 2nd

The correct answer is: Mandibular 2nd

The mandibular second premolar is the most likely missing in this scenario. One of the reasons for this is that the mandibular second premolar has a higher prevalence of being congenitally missing compared to the other premolars. Additionally, the mandibular second premolar is one of the most common teeth to be extracted due to various reasons such as dental caries, periodontal problems, or orthodontic treatment. Therefore, considering the usual patterns of tooth development and extraction, the mandibular second premolar is the most probable tooth to be missing out of the options provided. Maxillary first premolars are also commonly missing, but the mandibular second premolar has a higher likelihood of being missing.
