Which tooth has the most consistent number of canals?

Maxillary first molar
Mandibular second molar
Maxillary canine
Mandibular canine

The correct answer is: Maxillary canine

Maxillary canine has the most consistent number of canals among the four options. This is because it typically has only one root and one canal, while the other options can vary in the number of roots and canals present. For instance, the mandibular second molar can have anywhere from two to four canals, making it less consistent than the maxillary canine. The mandibular canine can also have one or two canals, making it less consistent as well. Additionally, the maxillary first molar can have three, four, or even five canals, depending on the individual tooth. Therefore, the maxillary canine is the most consistent in terms of the number of canals.
