Population
Adults and children (general population)
Intervention
Xylitol-only sugar-free chewing gum
Comparison
Pooled controls: no gum, placebo/control gum, probiotic, or fluoride varnish
Outcome
Streptococcus mutans load in the oral cavity (saliva and/or dental plaque)

Xylitol-only sugar-free gum significantly reduced Streptococcus mutans load versus pooled controls (SMD -0.46, 95% CI -0.64 to -0.28; 12 trials, I2 43%); certainty not formally graded.

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.
