Which tooth is represented as tooth number 24 in the Universal Numbering System?

In the Universal Numbering System, tooth number 24 refers specifically to the primary mandibular left lateral incisor. This is part of a standardized system used to identify teeth within the dental field, where primary teeth are numbered from A to T, with numbers assigned to their permanent counterparts as well.

Tooth number 24, in terms of the primary dentition, corresponds to the second left incisor in the lower jaw. This can be visualized by understanding the layout of teeth: primary teeth are typically numbered in a systematic manner, with incisors and canines identified in a specific order.

Understanding its positioning as a left lateral incisor helps clarify its role in dental anatomy, being adjacent to the primary mandibular left central incisor and contributing to the overall function of the dental arch. This designation aligns tooth number 24 correctly within the context of both primary teeth and their relationship to permanent teeth, which aids clinical communication and treatment planning in dentistry.
