This is a système à two-digit utilisé in the world. For the permanent or adult teeth, the mouth is divisée in the quadrants numérotés de 1 à 4 in the direction of the needles of a watch, commen&case;ant by the c&taxes;té supérieur right or the c&taxes;té law of mâjaw supéearlier, as seen by the dentist. It should be noted that the patient's right would be the c&taxes;té the left side of the dental card. Each tooth is numérotée on the basis of the quadrant and its position. Thus, in the first quadrant, that is to say, the c&taxes;té law of mâjaw supélimit à from the central incisor, the central incisor will be numérotée 11, the tooth next to the incisor latérale of the first quadrant will be numérotée 12. The numérotation of the teeth in the first quadrant will continue in this manière, jusqu'à la troisième molar that will be numérotée 18. M&stop, me, the teeth of the secondème quadrant (central incisor à la troisième molar) or of the c&taxes;té the left side of the mâjaw supéthan to be numérotées as follows: 21, 22, 23, 24, 25, 26, 27 and 28). The adult teeth of the troisième and fourème quadrants would be numérotées of 31 to 38 and 41 to 48 respectively.

In the case of the 20 milk teeth, the mouth is divisée into four quadrants numérotés 5 à 8 in the direction of the needles of a watch, commen&case;ant by the c&taxes;té supérieur right or the c&taxes;té law of mâjaw supéjaw (central incisor, jusqu'à the secondème primary molar). observé by the dentist. Once again, the child's right would correspond to the c&taxes;té the left side of the dental card. Each tooth is numérotée on the basis of the quadrant and its position. Therefore, in the quadrant supérieur right, that is to say, the c&taxes;té law of mâjaw supélimit à from the central incisor, the central incisor will be numérotée 51, the tooth next to the incisor latérale of the first quadrant will be numérotée 52. The numérotation of the teeth in this quadrant will continue in this manière, jusqu'à the secondème primary molar, which will be numérotée 55. M&stop, me, the teeth in the quadrant supérieur left one (central incisor à the secondème primary molar) or the c&taxes;té the left side of the mâjaw supéthan to be numéroté as (61, 62, 63, 64 and 65). The teeth of the quadrants inférieur left and inférieur right would be, respectively, the numérotées from 71 to 75 and 81 to 85 (Têyou spare a contra-angle).

Although it is easier to référer to names spéspecific donnés à each tooth, tables, dental or systèmes de numérotation of the teeth are tools utilisés by the dentists for se référer to adult teeth or primary. If you look at the charts dental to include the système numérotation of the teeth, you will realize that the système numérotation is not so difficult to understand (Dédetector dental caries).
