Which is the widest MD primary tooth?

Primary maxillary first molar
Primary mandibular first molar
Primary mandibular second molar
Primary maxillary second molar

The correct answer is: Primary mandibular second molar

The primary mandibular second molar is the widest MD (mesiodistal) primary tooth because it has a larger mesial and distal dimensions compared to the primary maxillary first molar (option A), primary mandibular first molar (option B) and primary maxillary second molar (option D). This means that the widest part of the primary mandibular second molar extends further towards the front and back of the mouth compared to the other three options. As a result, the primary mandibular second molar has a greater overall width than the other three options, making it the widest MD primary tooth.
