Atraumatic Restorative Treatment: Restorative Component.

Atraumatic restorative treatment (ART) is a method of managing dental caries based on 2 pillars: sealants for preventing carious lesions in pits and fissures, and restorations for cavitated dentine carious lesions. ART uses only hand instruments for opening/enlarging the cavity and for removing carious tissue. The amount of carious tissue that should be removed depends mainly on the cavity depth. In cavities of shallow and medium depth, carious tissue is removed up to firm dentine. In deep/very deep cavities, in which there is no sign of pulp exposure, pulp inflammation and/or history of spontaneous pain, some soft dentine can be left in the pulpal floor/wall with the aim of avoiding pulp exposure. The ART restorative method is indicated for treating single-surface cavities in primary and permanent teeth, and in multiple-surface cavities in primary teeth. Insufficient information is available to conclude on its use for treating multiple-surface cavities in permanent teeth.
