Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Inter
20、national 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 standardization.The procedures used to develop this document and those inte

26、al information by wire, printed documents and orally, has required that 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 Wor
27、ld Health Organization (WHO) and Technical committee ISO/TC 106, Dentistry, 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 ada
28、ptable to standard charts used in general dental practice.EN ISO 3950:2016 (E) DIN EN ISO 3950:2016-09 5 1 ScopeThis International Standard provides a system for designating teeth or areas of the oral cavity using two digits.2 PrinciplesThe anatomical arrangement of normal dental arches with respect
29、 to sagittal medial and occlusal planes allows for logical division of the oral cavity in quadrants and sextants.A quadrant, in this context, means one 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 sh
30、all be designated by a two digit code.Codes containing at least one zero (0) designate areas of the oral cavity.Replacement of a zero (0) by a nine (9) identifies the presence of an anomaly in that specific area of the oral cavity.Codes without a zero (0) identify individual teeth. The first digit o
31、f the code designates the quadrant and differentiates between deciduous and permanent teeth, and the second identifies the tooth itself.Numerals used for designation of areas of the oral cavity, teeth, sextants or quadrants shall be expressed in letters and the corresponding number given in parenthe
32、sis. For example: Zero (0) one (1) designates the maxillary area; Three (3) zero (0) designates the lower left quadrant; One (1) one (1) designates the central incisor of the maxillary right; Nine (9) four (4) designates any anomaly in the upper anterior sextant.3 Designation of areas of the oral ca
