23、to store information, together with the increasing necessity for the communication of dental 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 S
24、tandard was originally drawn up by the FDI World Dental Federation and approved by the World 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
25、communicable in print and by wire;d) easy to translate into computer “input”;e) easily adaptable to standard charts used in general dental practice. ISO 2016 All rights reserved vBS EN ISO 3950:2016BS EN ISO 3950:2016Dentistry Designation system for teeth and areas of the oral cavity1 ScopeThis Inte
26、rnational 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 to sagittal medial and occlusal planes allows for logical division of the oral cavity in quadrants and sextants.A quadra
27、nt, 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 shall be designated by a two digit code.Codes containing at least one zero (0) designate areas of the oral cavity.Replaceme
28、nt 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 of the code designates the quadrant and differentiates between deciduous and permanent teeth, and the second identifies th
29、e 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 parenthesis. For example: Zero (0) one (1) designates the maxillary area; Three (3) zero (0) designates the lower left quadrant;
30、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 cavity00 designates the entire oral cavity01 designates the maxillary area02 designates the mandibular area10 designates th
