Gum chewing (sugar-free) vs Pooled controls: no gum, placebo/control gum, probiotic, or fluoride varnish

Streptococcus mutans load in the oral cavity (saliva and/or dental plaque) · Adults and children (general population)

In a sensitivity analysis assuming a 0.95 baseline-to-endpoint correlation for the sugar-free gum arm, the effect remained significant (SMD -0.55, 95% CI -0.80 to -0.30; 13 trials, I2 73%); certainty not formally graded.

Hall technique vs Non-restorative cavity control (NRCC)

Failure of therapy · Children and/or adults with permanent or primary teeth, vital (sensitive) pulps, and cavitated or dentine carious lesions conventionally…

It is very uncertain whether hall Technique (sealing with a preformed metal crown) changes failure of therapy compared with non-restorative cavity control (NRCC) (very low certainty).

Xylitol-only sugar-free chewing gum vs Pooled controls: no gum, placebo/control gum, probiotic, or fluoride varnish

Streptococcus mutans load in the oral cavity (saliva and/or dental plaque) · Adults and children (general population)

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.
