34、ical devices used in dentistry. It is to be used in conjunction with the ISO 10993 series of standards. This International Standard contains special tests, for which ample experience exists in dentistry and which acknowledge the special needs of dentistry. Only test methods for which the members of

35、the committee considered there was sufficient published data have been included. In recommending test methods, the need to minimize the use of animals was given a high priority. It is essential that the decision to undertake tests involving animals be reached only after a full and careful review of

36、the evidence indicating that a similar outcome cannot be achieved by other types of test. In order to keep the number of animals required for tests to an absolute minimum, consistent with achieving the objective indicated, it can be appropriate to conduct more than one type of test on the same anima

37、l at the same time, e.g. pulp and dentin usage test and pulp capping test. However, in accordance with ISO 10993-2 these tests are performed both in an efficient and humane way. On all occasions when animal testing is undertaken, such tests are conducted empathetically and according to standardized

38、procedures as described for each test. This International Standard does not explicitly describe test methods for occupationally related risks. Annexes B and C are included to encourage the development of in vitro and ex vivo test methods which will further reduce the use of animals in the evaluation

39、 of the biocompatibility of medical devices used in dentistry. DIN EN ISO 7405:2013-12 EN ISO 7405:2008 + A1:2013 (E) 4 1 Scope This International Standard specifies test methods for the evaluation of biological effects of medical devices used in dentistry. It includes testing of pharmacological age

40、nts that are an integral part of the device under test. This International Standard does not cover testing of materials and devices that do not come into direct or indirect contact with the patients body. 2 Normative references The following referenced documents are indispensable for the application
