Nd:YAG laser vs No anticaries intervention (untreated enamel): Enamel acid resistance (cross-sectional microhardness)
Nd:YAG laser increased enamel acid resistance versus untreated enamel in pits and fissures (ungraded, 1 ex-vivo study, no pooled estimate).

Nd:YAG laser irradiation vs Untreated control enamel Enamel acid resistance (cross-sectional microhardness) · Human enamel in pits and fissures (in situ / ex vivo) · Ex-vivo/in situ (laboratory) Nd:YAG laser increased enamel acid resistance versus untreated enamel in pits and fissures (ungraded, 1 ex-vivo study, no pooled estimate). Clinical and ex-vivo effect of LASERs on prevention of early-enamel caries: systematic review & meta-analyses. (2024) All outcomes | Narrative only (not meta-analyzed). Correa-Afonso: Nd:YAG (and CO2) laser increased enamel acid resistance in pits and fissures; microhardness of the Nd:YAG group was higher than the control group. | 1 study | GRADE not reported |
Findings are shown side by side, never pooled across reviews.

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
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.
