EN ISO 6360-5:2007 (E) DIN EN ISO 6360-5:2008-03 Introduction This part of ISO 6360 is one of a series of International Standards relating to dental rotary instruments
20、. A wide variety of dental rotary instruments, including root-canal instruments, is manufactured throughout the world for use by the dental profession. ISO 6360 provides a general number coding system for all types of dental rotary instruments, including accessories used in connection with these rot
21、ary instruments. The benefits of this system for dentistry in its entirety will only be derived if the system is widely adopted; manufacturers of dental instruments, as well as the dental trade, are therefore requested to refer to ISO 6360 in their catalogues. This part of ISO 6360 was prepared in r
22、esponse to a need by the dental trade and industry, and the dental profession, for a universal system of classification and designation for these instruments. It establishes a comprehensive number coding system suitable for all dental rotary instruments by use of a 15-digit code number identifying g
23、eneral and specific characteristics of instruments or groups of instruments. The first group of three digits identifies the materials used for the working part of instruments. The second group of three digits identifies the shanks and handles used for instruments and the overall lengths of instrumen
24、ts. The third group of three digits identifies the shapes of instruments. The fourth group of three digits identifies the specific characteristics for groups of instruments. The fifth group of three digits identifies the nominal diameter of the working part of the instruments. The code numbers are g
25、eneric code numbers. They do not provide exact product information. This information is given in the respective product standard for dental rotary instruments. For the application of the system and for the correct allocation of numbers or their identification, it is intended that the user consult IS
26、O 6360-1 and ISO 6360-2 for general information, and in addition one of the following subsequent parts (ISO 6360-3 to ISO 6360-7) for further information on specific characteristics of instruments or groups of instruments. For the allocation of new numbers complying with ISO 6360, an application sup
27、ported by a description and a drawing should be sent to the secretariat of ISO/TC 106/SC 4, Dental instruments, which keeps updated records of all numbers currently allocated. An international group of experts will then decide on an appropriate identification number for the instrument in question, i
28、ncluding its specific characteristics. The Secretary will inform the applicant, in due course, of the result and assist him in using the number correctly.

33、canal instruments consists of a 15-digit overall number. The general characteristics of the number coding system for rotary instruments including root-canal instruments are described in ISO 6360-1. The first and second groups of three digits are specified in ISO 6360-1. The shapes and designs of roo
34、t-canal instruments are described in ISO 6360-2:2004, Table 5, in the code number ranging from 880 to 999. The shapes and their respective numbers are specified in ISO 6360-2 as the third group. 4 EN ISO 6360-5:2007 (E) DIN EN ISO 6360-5:2008-03 The specific characteristics of root-canal instruments
35、 are described in this part of ISO 6360. The nominal sizes of the operative part are described in ISO 3630-1. 4.2 Groups The number coding system for root-canal instruments consists of 15 digits, separated into five groups: 000 000 000 000 000 First group: digits 1 and 2: material of operative part
36、(see ISO 6360-1:2004, Table 1). digit 3: coating of operative part (see ISO 6360-1:2004, Table 2). Second group: digits 4 and 5: type of shank or handle (see ISO 6360-1:2004, Table 4). digit 6: code for overall length (see ISO 6360-1:2004, 5.5 and Table 5). Third group: digit 7, digit 8 and digit 9:
37、 shape of operative part (see ISO 6360-2:2004, Table 5). Fourth group: digit 10 and digit 11: length of operative part (see ISO 3630-1). digit 12: taper of operative part.

41、l instruments. The length of the operative part of a root-canal instrument is identified by the tenth and eleventh digits and the taper of the working part is identified by the twelfth digit. 5.2 Length of operative part of root-canal instrument The operative part of root-canal instruments is consid
42、ered as the portion from the tip to the handle or shank of the root-canal instrument. The length of the operative part is given in the locations 10 and 11. The length of the operative part of root-canal instruments is identified in millimetres. 5.3 Taper of working part of root-canal instruments The
43、 taper of the working part of root-canal instruments is given in the location 12. The taper of the working part of root-canal instruments is identified, in percent, as the enlargement of the diameter of the working part, in millimetres per millimetre length of root-canal instrument. The taper is rou
44、nded to the nearest percent. The numbers for the taper range from zero to nine. The numbers 0 up to 8 indicate the taper in percent. The number 9 is used for tapers greater than 8 %. In this case, the taper is indicated by the shape number given in ISO 6360-2:2004, Table 5. EXAMPLE 1 If the taper al
45、ong the working part is 0,02:1, the taper, in percent, is 2 %. The code number for these root-canal instruments is 2. EXAMPLE 2 Taper sizes of 10 % and 12 % are identified in the digits for the shape and design (i.e. digits 7 to 9) by different shape numbers (see ISO 6360-2:2004, Table 5). The code
46、number for these root-canal instruments is 9. EXAMPLE 3 If a root-canal instrument has no taper (i.e. the taper is 0 %), the twelfth digit is 0. The code number for these root-canal instruments is 0. EXAMPLE 4 If a root-canal instrument has an irregular shape (e.g. arc shape), or has more than one t
47、aper, the twelfth digit is 0. The code number for these root-canal instruments is 0. 6 EN ISO 6360-5:2007 (E) DIN EN ISO 6360-5:2008-03 Bibliography 1 ISO 1797-1, Dental rotary instruments Shanks Part 1: Shanks made of metals 2 ISO 1797-2, Dental rotary instruments Shanks Part 2: Shanks made of plastics 7 EN ISO 6360-5:2007 (E) DIN EN ISO 6360-5:2008-03
