“…In terms of caries risk levels, 2 studies reported high risk [21,46,47], 4 studies reported moderate to high risk [33,34,37,39,40], 1 study reported low to moderate risk [38], 2 studies reported low to high risk [36,42], 3 studies reported mixed risk levels [23,41,[43][44][45] and 4 studies did not report caries risk in the articles [19,20,22,35,48]. Four caries risk statuses were included in the subgroup analysis: low [42], low to moderate [38], moderate to high [33,34,37,39,40] and high [21,42,46,47]. All trials used radiographic lesion progression as the primary outcome.…”
