Introduction The reorganization of ISO 3630 is intended to present the requirements and test methods for root-canal instruments in an orderly manner. This part of

27、ISO 3630 defines general requirements and test methods. Subsequent parts provide the specific requirements and test methods, if applicable, for two areas of endodontic procedures. These parts are enlargers, condensers and auxiliary instruments. With current use of nickel-titanium (Ni-Ti) alloys for

28、manufacture of root canal instruments a need for adequate expertise in their safe use is recommended. Instruments made of Ni-Ti can be easily broken near the tip if manufacturers cautions are not understood and practiced. This part of ISO 3630 does not attempt to provide information for proper use o

29、f any instruments. The sizes of the root-canal obturating points (cones) specified in ISO 68774have to be aligned with the corresponding sizes for root-canal instruments specified in ISO 3630. 4 DIN EN ISO 3630-1:2008-04 EN ISO 3630-1:2008 (E) 1 Scope This part of ISO 3630 specifies general requirem

30、ents and test methods for root-canal instruments used for endodontic purposes, e.g. enlargers, shaping and cleaning instruments, condensers, and accessory instruments. In addition it covers general size designations, colour coding, packaging and identification symbols. 2 Normative references The fol

Type 1: standard-sized instruments (taper = 2 %); Typ

44、e 2: taper-sized instruments (taper other than 2 %); Type 3: shape-sized instruments (arc shape); Type 4: non-taper-sized instruments (zero taper); Type 5: non-uniform taper-sized instruments (more than one taper). 5 Requirements 5.1 General Specific root-canal instrument types, such as enlargers, h

45、ave unique shapes which are not included here. These cases are covered in ISO 3630-2 and ISO 3630-3. 5.2 Type 1: standard-sized instruments 5.2.1 Length The length of the working part, l3, shall be a minimum of 16 mm unless otherwise specified by the manufacturer. The lengths of the working part, wh
