Initiation of white spot lesions (WSL), visual-tactile assessment · Patients of any age (11-40 years) receiving comprehensive/fixed orthodontic treatment with fixed appliances
Among fluoride-releasing sealants, the reduction in WSL initiation versus no sealant was not statistically significant (RR 0.69); subgroup not separately GRADE-rated.

Optical/esthetic improvement (visual-tactile assessment) · Patients with post-orthodontic white spot lesions (WSL)
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).
