Correct answer: A — 13
In the FDI (Fédération Dentaire Internationale) two-digit notation system used internationally and in Canada, the first digit indicates the quadrant (1 = upper right, 2 = upper left, 3 = lower left, 4 = lower right for permanent teeth; 5-8 for primary teeth) and the second digit indicates the tooth position from the midline (1 = central incisor through 8 = third molar). Therefore, the permanent maxillary right canine = quadrant 1 + tooth 3 = 13.
