Erbium:YAG laser vs Untreated / high-speed-handpiece control enamel: Enamel resistance to demineralization (microhardness / lesion depth)
Er:YAG laser showed a mixed and limited effect on enamel resistance to demineralization: feasible for controlling progression around restorations but not preventing caries formation, and ineffective in pits and fissures (ungraded, 2 ex-vivo studies, no pooled estimate).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
