[Atraumatic Restorative Treatment (ART). A special tissue preservative and patient-friendly approach].
ABSTRACT The number of studies investigating aspects of the ART-approach has increased in recent years. This tissue preservative treatment concept appears to be less painful and is, therefore, more patient-friendly than conventional treatments. The investigations so far have shown that the ART-approach is indicated for treating single-surface cavities in both primary 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 3 years. ART sealants using high-viscosity glass-ionomers seem to be retained longer than ART sealants using low-viscosity glass-ionomers after 3 years. The surface wear of ART restorations using high-viscosity glass-ionomers after two years is low. It can be concluded that the ART approach is beneficial in improving the oral health of many people, not only in developing but also in more advanced countries. The full benefit of the ART-approach is not yet known.
