Painting the future for ART

The objective of this paper is to review recent research and developments with respect to the atraumatic restorative treatment (ART) approach and to outline future areas of research and development. Areas identified as requiring further investigation include the evaluation of: ART restorations far longer than 3 years duration using recognised evaluation criteria, multi-surface ART restorations, ART restorations in primary teeth and ART sealants. Ln addition, the possibility and potential dangers of caries remaining after cavity cleaning with hand instruments must be investigated and the findings balanced against the known damage to sound tooth tissue caused by more routine cavity preparation techniques. New bioactive restorative materials which offer the possibility of healing dentinal caries lesions should be developed and evaluated. Finally, behavioural and educational aspects of the ART approach should be investigated.
