3. Types of numbering system’s. There are several systems in world, 3 main systems are : Universal Notation System. Zsigmondy/Palmer Notation System. Federation Dentaire Internationale (FDI).

4. PRIMARY DENTITION Dental formula for the deciduous teeth

5. PERMANENT DENTITION Dental formula for the permanent human dentition is as follows

6. Universal Notation System The universal system of notation for the primary dentition uses ‘uppercase letters’ for each of the primary teeth. For the maxillary teeth, beginning with the right second molar, letters A through J, and for the mandibular teeth, letters K through T, beginning with the left mandibular second molar. The ADA in 1968 officially recommended the “universal” numbering system. 2) For the permanent teeth ; 1)For the primary teeth ;

7. Universal Notation System The universal system of notation for the permanent dentition uses ‘numbers’ for each of the permanent teeth. The maxillary teeth are numbered from 1 through 16, beginning with the right third molar. Beginning with the mandibular left third molar, the teeth are numbered 17 through 32.

8. Zsigmondy/Palmer Notation System. Symbolic system In this system the arches are divided into quadrants. - upper right - upper left - lower right - lower left The Palmer notation for the entire deciduous dentition is as follows:

9. Zsigmondy/Palmer Notation System. For the permanent dentition is a four-quadrant symbolic system. Beginning with the central incisors, the teeth are numbered 1 through 8 (or more) in each arch. - upper right - upper left - lower right - lower left

10. Federation Dentaire Internationale (FDI). Two-digit system. Proposed by FDI has been Adopted by the WHO and by other organizations such as the International Association for Dental Research. The first digit indicates the quadrant: 5 to 8 for the primary dentition. The second digit indicates the tooth within a quadrant 1 to 5 for the primary teeth.

11. Federation Dentaire Internationale (FDI). The first digit indicates the quadrant: 1 to 4 for the permanent dentition. The second digit indicates the tooth within a quadrant:1 to 8 for the permanent teeth. For example, the permanent upper right central incisor is 11 (pronounced “one one,” not “eleven”).
