NATIONAL FOREWORD

This Indian Standard ( Part 3 ) ( Second Revision ) which is identical with 1S0 1942-3:1989 ‘Dentalvocabulary - Part 3: Dental instruments’ issued by the International Organization40r Standardization( ISO ) was adopted by the Bureau of Indian Standards on the recommendations of the DentistrySectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.

This standard was first published in 1975 as Part 2 and revised in 1982 to align it with the correspondingISO 1942-1 : 1977-and ISO 1942-3:1977. Its second revision has been undertaken to adopt revisedISO 1942-3:1989 with a view to cover the latest terminology followed at the international level.

This standard under-the general title ‘Dental Vocabulary’ is being published in five parts. Other parts inthis series are as follows:

Part 1 General and clinical .terms

Part 2 Dental materials

Part 4 Dental equipment

Part 5 Terms associated with testing

The text of ISO Standard has been approved as suitable for publication as Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should beread as ‘Indian Standard’; and

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point ( . ) as the decimal marker.

Only the English Ianguagetext of the International Standard ( including alphabetical index ) has beenadopted in this Indian Standard.

Amendments 1 and 2 of 1992 have been issued to IS-O 1942-3:1989, adding in numerical sequencecertain terms, which have been included in continuation of the existing text of this standard( From 3.280 onwards).
