Here is your answer to the Monday #NBDE question: Which is the correct universal number for the permanent mandibular left canine? Answer: E. #22 Rationale: Universal Numbering System: •Permanent Teeth- the upper right 3rd molar is #1, the upper right 2nd molar #2, and so forth around the entire maxillary arch to the upper left 3rd molar, which is #16. The lower left 3rd molar is #17, and continues around the mandibular arch until the lower right 3rd molar is #32. •Primary Teeth- the twenty teeth of the primary dentition are numbered in the same manner as are the permanent teeth (1-20), except that a small -d- is added as a suffix to each number to designate primary. Thus, the primary upper right 2nd molar is #1 d, while the upper left 2nd molar is #10 d. The letters A through T can also be used for primary teeth.
