Two studies compared resin infiltration with microabrasion, but no pooled or comparative effect estimate was reported (ungraded).
Resin infiltration alone produced greater dentist-rated masking than in-office bleaching alone in one study (MD 3.97, 95% CI 3.33 to 4.61; ungraded).
Bleaching before resin infiltration did not improve masking of fluorosis compared with infiltration alone (MD -0.30, 95% CI -0.98 to 0.39; moderate certainty).
One study reported machine-learning accuracy for root caries detection (97.1%, support vector machine); not pooled and not graded.
Resin infiltration produced significantly greater optical improvement of white spot lesions than untreated (naturally remineralizing) controls (SMD 1.24, 95% CI 0.59 to 1.88; moderate certainty).
Patient/dentist satisfaction did not differ between bleaching-then-infiltration and infiltration alone (SMD -1.53, 95% CI -4.75 to 1.70; ungraded).
Resin infiltration produced significantly greater optical improvement than fluoride varnish (MD 4.76, 95% CI 0.74 to 8.78; moderate certainty).
