There was no difference between the vertical marginal gaps of the CAD/CAM and WAX/CAM. The WAX/CAST technique resulted in smaller vertical marginal gaps than either CAD/CAM or WAX/CAM.

Background: The most common adjunct to the visual and tactile clinical examination for dental caries is the bitewing radiograph. The aim of this study was to report on treatment planning decisions made by Victorian dentists when given a range of predetermined radiographic scenarios. Methods: A postal survey was conducted to obtain data from 550 dentists selected systematically (every fourth dentist) from the register of the Dental Board of Victoria (1996). Results: The survey response rate was 64 per cent. Fifty per cent of responding dentists selected an operative intervention for radiographic lesions confined to enamel. Conclusions: A review of current dental literature does not support this approach because a large proportion of proximal tooth surfaces that have associated radiolucencies confined to enamel are not cavitated. This study supports the need for continuing education programmes on the management of dental caries; such programmes should follow an evidence-based model.

This article describes a simplified technique for creating a soft tissue masque to aid in shaping the gingival contours of fixed restorations. The additional clinical visit that has been previously described is circumvented, and only one master cast is required.
