title: Initial stages in the development of valid criteria for the replacement of amalgam restorations.
abstract: OBJECTIVE
  Replacement amalgam restorations account for the largest single cost in the General Dental Services in Scotland. There is little practical advice available to practitioners on the maintenance and replacement of amalgam restorations. A distance learning package is being prepared for distribution to general dental practitioners in Scotland and this paper describes the initial stages in the development of the policy statements for the proposed package.
  
  
  METHODS
  In the first stage proposals are being developed by a panel of dental academics using a modified Delphi technique. This technique is designed to produce a consensus view. Seventeen statements have been set out by the expert group.
  
  
  CONCLUSIONS
  While agreement was rapidly reached that 'ditching' of amalgam restoration margins did not justify their replacement and that repair was preferable to total replacement, some difficulty was experienced in arriving at a consensus view on the correct management of 'white spot' lesions at restoration margins and dentinal staining adjacent to amalgam restorations. The next stage in the development will be to present these statements to a selected panel of general dental practitioners and to develop their consensus view of the proposals, again using the Delphi technique.
