ART: a minimal intervention approach to manage dental caries.

The number of studies investigating aspects of the Atraumatic Restorative Treatment (ART) approach has increased in recent years. This tissue preservative treatment approach appears to be less painful and is, therefore, more patient-friendly than conventional caries treatments. The investigations so far have shown that the ART approach is effective for the management of single-surface cavities in both deciduous and permanent dentitions. There appears to be no difference in survival results between single-surface ART restorations and comparable amalgam restorations in the permanent dentition after three years. The surface wear of ART restorations using high-viscosity glass-ionomers after two years is low. ART sealants using high-viscosity glass-ionomers are retained longer than ART sealants using low-viscosity glass-ionomers after three years. It is concluded that the ART approach is beneficial in improving the oral health of many, not only in developing but also in more advanced countries.
