Glass ionomer cement vs Resin composite restoration: Secondary caries
- Population
- Patients requiring dental restoration; permanent teeth
- Intervention
- Glass ionomer cement
- Comparison
- Resin composite restoration
- Outcome
- Secondary caries
Over 2 or more years in permanent teeth, GIC probably reduces secondary caries versus resin composite (RR 0.50, 95% CI 0.28-0.91; moderate certainty).

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.
