Fig. 1From: Impact of non-restorative cavity control on proximal carious lesions of anterior primary teeth on the tooth survival and patient-centered outcomes (CEPECO 2): study protocol for a non-inferiority randomized clinical trialIllustration of NRCC treatment. Dashed lines represent the cavity’s size limit to be included in the study (up to one-third of the buccal and/or lingual surfaces involved in the proximal carious lesion). In the first image, we can observe a proximal carious lesion in the upper incisor. This cavity will be enlarged with metallic sandpaper in the buccal and lingual direction, exposing the cavity, as demonstrated in the second imageBack to article page
