Another approach of treating dental caries in young children is Atraumatic Restorative Treatment (ART). The ART is a procedure based on removing carious tooth tissues using hand instruments alone and restoring the cavity with an adhesive restorative material. This is useful to prevent trauma and requires less chair time for the young patients. This is used in cases where the teeth are being maintained in the mouth to maintain space for the future teeth to come through. Low quality evidence indicates that ART may have a higher risk of filling failure when compared to usual care. Despite the potential for filling failure, ART is still recommended for children when access to electricity, drills, dentists, or other dental resources are limited.
