with the number "2", the lower left with "3", and the lower right with "4". For primary teeth, the sequence of numbers similarly is 5, 6, 7, and 8 for the teeth in the upper right, upper left, lower left, and lower right respectively. When speaking about a certain tooth such as the permanent maxillary central incisor, the notation is pronounced “one, one”.
230:
The FDI notation uses a two-digit numbering system in which the first digit represents a tooth's quadrant and the second digit represents the number of the tooth from the midline of the face. For permanent teeth, the patient's upper right teeth begin with the number "1", the upper left teeth begin
1046:
To prevent uncertainty or ambiguity, teeth may be indicated using more than one notation, particularly when referring for an extraction; this makes it less likely for the incorrect tooth to be needlessly extracted. For instance, a dentist may give an instruction to "extract the 24 (UL4)" for the
431:
The Palmer notation consists of a symbol (┘└ ┐┌) designating the quadrant of the tooth and a number indicating the position from the midline. Adult teeth are numbered 1 to 8, with primary teeth indicated by a letter A to E. Hence the left and right maxillary central incisor would have the same
427:
Permanent teeth (adult) were numbered 1 to 8, and the child primary dentition (also called deciduous, milk or baby teeth) were depicted with a quadrant grid using Roman numerals I, II, III, IV, V to number the teeth from the midline distally. Palmer changed this to A, B, C, D, E.

Within each quadrant, the teeth are numbered as in the Palmer notation: 1–8 for permanent and A-E for deciduous, both starting at the midline. For example, the permanent left maxillary first molar is designated
