Gum chewing (sugar-free) vs No chewing gum: Plaque
- Population
- Adults and children (predominantly adults; one study in children), with natural dentition
- Intervention
- Gum chewing (sugar-free)
- Comparison
- No chewing gum
- Outcome
- Plaque
Sugar-free chewing gum significantly reduced plaque quantity versus no-gum/control (SMD -0.778, 95% CI -1.167 to -0.390), with high heterogeneity (I2 = 86.6%) and no GRADE rating (ungraded).

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.
