18、. 8BS EN ISO 29022:2013ISO 29022:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod
19、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote
20、chnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by t
21、he technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.ISO 29022 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 1, Filling and restorative mate

23、takes no position concerning the evidence, validity and scope of this patent right.The holder of this patent right has ensured ISO that he/she is willing to negotiate licenses under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the stat
24、ement of the holder of this patent right is registered with ISO. Information may be obtained from:Neil T. Jessop, Ultradent Products, Inc., 505 West 10200 South, South Jordan, Utah 84095-3942, USA.Attention is drawn to the possibility that some of the elements of this document may be the subject of
25、patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights.The purpose of this International Standard is to establish a simple and easy to use method for documenting a claim that a material adheres to tooth substance. While the me
26、thod described in this International Standard has been used for comparing dental adhesive materials, users of this International Standard should evaluate usefulness of this method for their particular application(s). There is a variety of other dental adhesion test methods that may also be suitable
27、or preferable, depending on the objective (e.g. academic research). ISO 2013 All rights reserved vBS EN ISO 29022:2013BS EN ISO 29022:2013Dentistry Adhesion Notched-edge shear bond strength test1 ScopeThis International Standard specifies a shear test method used to determine the adhesive bond stren
28、gth between direct dental restorative materials and tooth structure, e.g. dentine or enamel. The method as described is principally intended for dental adhesives. The method includes substrate selection, storage and handling of tooth structure, as well as the procedure for testing.NOTE 1 Testing adh
29、esion to tooth structure is technique sensitive and experience with the test method is required.NOTE 2 With modification, it may be possible to use this method for adhesive restorative materials (e.g. glass-ionomer materials).2 Normative referencesThe following documents, in whole or in part, are no

Record the type of substrate used.INTERNATIONAL STANDARD ISO 29022:2013(E) ISO 2013 All rights reserv
34、ed 1BS EN ISO 29022:2013ISO 29022:2013(E)For bovine teeth, use the labial surface. For human teeth, use the buccal, mesial, distal or lingual surface.NOTE The occlusal surface of human teeth should not be used due to difficulty in finding a suitable bonding area.Use superficial dentine, i.e. as clos
35、e to enamel as possible, in order to reduce variations. It is important that the planed dentine surface follow the anatomical plane of the dentine-enamel junction (interface) as closely as possible in order to produce a uniform dentine structure.4.2 Time after extractionUse teeth within 6 months aft
36、er extraction.NOTE Teeth extracted more than 6 months prior to use may undergo degenerative changes in dentinal proteins.4.3 Condition of teethUse caries-free teeth for bond strength measurement. Do not use human teeth which are restored or are root-filled teeth (endodontically treated).4.4 Initial
37、preparation and storage of teethFor bovine teeth, cut off the roots at the cemento-enamel junction (CEJ) and remove the pulp. For human teeth, wash thoroughly in running water and remove all blood and adherent tissue as soon as possible after extraction.Place the teeth in water (ISO 3696, grade 3) a
38、t (4 4)C. To minimize deterioration, replace the storage medium at least once every 2 months.Preservatives which do not react with dentine, e.g. 1 % aqueous solution of chloramine-T, may be used. Do not use preservatives which can react with dentine, e.g. aldehydes, or which can inhibit radical poly
39、merization, e.g. phenols. If storage in a preservative has taken place, thoroughly rinse the teeth in running water to remove any preservative solution prior to tooth surface preparation.5 Tooth surface preparation5.1 GeneralA standard, reproducible, flat surface is required. Keep tooth surfaces wet
40、 at all times.NOTE Exposure of a tooth surface to the air for several minutes may cause irreversible changes in bonding character. Dentine is especially sensitive to dehydration.5.2 Potting (mounting) of teethPrior to potting the teeth, block the opening to the pulp chamber with wax or dental cement
41、. Alternatively, use a high viscosity potting medium that does not penetrate the pulp chamber. This can be verified by preparing a set of potted teeth, sectioning them and examining the pulp chambers. Discard the sectioned specimens.Place the tooth bonding side down (labial side down for bovine teet
42、h; buccal, mesial, distal or lingual side down for human teeth) in a cylindrical mould on a level working surface. Plastics or metal rings of approximately 25 mm internal diameter may be used. The height of the mould may vary; 10 mm to 25 mm is suggested. If rings are used, a sheet of polyester or s
43、imilar film may be placed under the rings for easy removal and clean up. Pour a mixed slow-setting viscous self-curing resin or dental die stone into the mould. Remove the potted tooth from the mould as soon as possible after the potting medium has set. Store the potted tooth immediately in water (I
44、SO 3696, grade 3) at (4 4)C.NOTE 1 The heat of polymerization of self-curing resin may adversely affect the tooth. Samples may be cooled in an ice bath during polymerization of the resin.2 ISO 2013 All rights reservedBS EN ISO 29022:2013ISO 29022:2013(E)NOTE 2 It is preferable to pot teeth soon afte
45、r cutting off the roots and removing the pulp.NOTE 3 A small flat area which will be parallel to the final bonding surface may be ground in the enamel for easier placement and stabilization of the tooth during the potting process.5.3 Surface preparationFix silicon carbide abrasive paper, complying w
46、ith ISO 6344-1, to a hard, flat surface. No more than 4 h before the bonding procedure is planned, prepare a standard surface by a two-step sequential planing process under running water. First use P120 paper until a bonding area sufficient for placing a resin composite (composite) button with a dia
47、meter of 2,38 mm has been exposed, followed by P400 paper until the surface is even and smooth when visually inspected. For dentine, stop the grinding when superficial dentine is exposed. The median grit size for P120 abrasive paper is (125 1) m and for P400 abrasive paper is (35 1) m. If abrasive p
48、apers of grit size P120 or P400 are not available, use abrasive papers with grit size as close as possible to 125 m and 35 m.Grinding may be performed in an automatic grinding machine with rotating abrasive discs and running water. Use a mechanical fixture that orientates the abrasive paper perpendi
49、cular to the specimen. A suitable machine consists of a grinding mandrel with T-slot grinding plate. Alternatively, place the potted tooth into a fixture in a drill press (tooth orientated downwards), lower and press the rotating tooth against the abrasive paper on a motorized rotating lapidary wheel under running water.In order to ensure correct alignment in the bonding and test fixtures, ensure that the ground surface is perpendicular to the sides of the potted tooth cylinder and that the top and bottom surfaces of the spe
