Most common anterior tooth to have multiple canals?

Maxillary central
Mandibular lateral
Mandibular central
Maxillary lateral

The correct answer is: Mandibular central

The most common anterior tooth to have multiple canals is the mandibular central incisor. This tooth typically has two canals, known as a "Vertucci Type I" configuration, where the root canal system is usually divided into a mesial and distal canal. This anatomical variation makes the mandibular central incisor more likely to have multiple canals compared to other anterior teeth. Maxillary central incisors usually have a single canal, while mandibular lateral incisors and maxillary lateral incisors can occasionally have two canals but it is less common than in mandibular central incisors.
