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
