Answer: (B)

In the Universal Numbering System, each tooth is assigned a specific number for easy identification. The Mandibular left canine, which is located on the lower left side of the mouth, is designated as tooth number 22. This system assigns numbers to permanent teeth starting from the upper right third molar (tooth number 1) moving across the upper arch to the upper left third molar (tooth number 16), and then continues from the lower left third molar (tooth number 17) across to the lower right third molar (tooth number 32). The Mandibular canines are numbered consecutively, with the right canine being 27 and the left canine being 22. Understanding this sequence is crucial for dental professionals, as it facilitates accurate communication about a patient’s dental records and treatment plans. Thus, identifying tooth number 22 as the Mandibular left canine is essential for effective practice in dental assisting.
