Which is the widest FL tooth in primary dentition?

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

The correct answer is: Primary maxillary second molar

The primary maxillary second molar is the widest tooth in the primary dentition. This tooth typically has a more significant mesiodistal width compared to other primary teeth, making it the widest tooth in the primary dentition. Option B, the primary mandibular second molar, typically has a narrower width compared to the primary maxillary second molar and is not the widest tooth in the primary dentition. Options C and D, the primary maxillary and mandibular first molars, respectively, are wider than anterior teeth but not as wide as the primary maxillary second molar in the primary dentition.
