16、al Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been e
17、stablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standard
18、ization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for vo
19、ting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all su
20、ch patent rights. ISO 3950 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 3, Terminology.

22、at new basic elements be taken into consideration for drawing up a designation system for teeth. The system described in this International Standard was originally drawn up by the FDI World Dental Federation and approved by the World Health Organization (WHO) and Technical committee ISO/TC 106, Dent
23、istry, to satisfy the following requirements: a) simple to understand and teach; b) easy to pronounce in conversation and dictation; c) readily communicable in print and by wire; d) easy to translate into computer “input”; e) easily adaptable to standard charts used in general dental practice.

25、stem for designating teeth or areas of the oral cavity using two digits. 2 Principles The anatomical arrangement of normal dental arches with respect to sagittal medial, and occlusal planes allows for logical division of the oral cavity in quadrants and sextants. A quadrant, in this context, means o
26、ne of the fourths of the dental arches. A sextant in this context means one of the sixths of the dental arches. The areas of the oral cavity and teeth shall be designated by a two-digit code. Codes containing at least one zero designate areas of the oral cavity. Replacement of a zero by a nine ident
27、ifies the presence of an anomaly in that specific area of the oral cavity. Codes without a zero identify individual teeth. The first digit of the code designates the quadrant and differentiates between deciduous and permanent teeth, and the second identifies the tooth itself. 3 Designation of areas
28、of the oral cavity 00 designates the entire oral cavity 01 designates the maxillary area 02 designates the mandibular area 10 designates the upper right quadrant 20 designates the upper left quadrant 30 designates the lower left quadrant 40 designates the lower right quadrant 03 designates the upper

30、signates the lower anterior sextant 08 designates the lower right sextant 4 Designation of teeth a) First digit Digits 1 to 4 are used for the permanent dentition and digits 5 to 8 for the deciduous dentition. This designation starts clockwise from the upper right side. 1 designates permanent teeth
31、in upper right quadrant 2 designates permanent teeth in upper left quadrant 3 designates permanent teeth in lower left quadrant 4 designates permanent teeth in lower right quadrant 5 designates deciduous teeth in upper right quadrant 6 designates deciduous teeth in upper left quadrant 7 designates d
32、eciduous teeth in lower left quadrant 8 designates deciduous teeth in lower right quadrant b) Second digit (tooth) Teeth in the same quadrant are designated by the second digit 1 to 8 (1 to 5 in the deciduous dentition). This designation starts from the sagittal medial plane in the distal direction.
33、 Permanent dentition: 1 designates the central incisor 2 designates the lateral incisor 3 designates the canine 4 designates the first premolar 5 designates the second premolar 6 designates the first molar 7 designates the second molar 8 designates the third molar Licensed Copy: Wang Bin, ISO/EXCHAN
